The idea was to distill +the useful parts of other languages and combine them into a scripting +language, with type checking, classes (not full-blown OO but useful none +the less), and direct access to a cross-platform graphical toolkit. + +L provides a set of built-in functions, drawn from Perl and the +standard C library. + +L is built on top of the Tcl/TK system. The L compiler generates Tcl +byte codes and uses the Tcl calling convention. This means that L and +Tcl code may be intermixed. More importantly, it means that +L may use all of the TK widgets. The net result is a type-checked +scripting language which may be used for cross-platform GUIs. + +L is open source under the same license as Tcl/TK (BSD like). + +=head1 RUNNING L PROGRAMS + +You can run an L program from the command line. + + L [options] progname.l [args] + +Alternatively, put this as the first line of your script, but make +sure your script is executable (C<chmod 755 script.l> under Unix). + + #!/path/to/L [options] + +Options: + +=over 4 + +=item B<--fnhook=myhook> + +When function tracing is enabled, use C<myhook> as the trace hook. + +=item B<--fntrace=on | entry | exit | off> + +Enable function tracing on both function entry and exit, entry only, +exit only, or disable tracing altogether. + +=item B<--norun> + +Compile only (do not run). This is useful to check for compilation +errors. + +=item B<--nowarn> + +Disable compiler warnings. This is useful when you know you have +unused variables or other warnings that you don't want to be +bothered with. + +=item B<--poly> + +Treat all types as C<poly>. This effectively disables type checking. + +=item B<--trace-depth=n> + +When function tracing is enabled, trace only to a maximum call depth of n. + +=item B<--trace-file=colon-separated list of glob | /regexpr/> + +Enable tracing of all functions in the given files, specified either +as globs or regular expressions. A leading + before a glob or regexp +means to add to what is otherwise being traced and a leading - means +to remove. +No leading + or - means to trace exactly what is specified. + +=item B<--trace-funcs=colon-separated list of glob | /regexpr/> + +Like --trace-file but specifies functions. + +=item B<--trace-out=filename | host:port> + +Send default trace output to a file or a TCP socket. + +=item B<--warn-undefined-fns> + +Just before main() is called, warn if any functions referenced by +L code are undefined. +You can combine this with --norun to do this check even when no +code is run. + +=item B<--version> + +Print the L build version and immediately exit. + +=back + +Any of the command-line options also can be specified in a #pragma +inside the program. + +The optional [args] is a white-space separated list of arguments that +are passed to the script's main() function as an argument count (argc) +and an array of strings (argv). + +=head1 SYNTAX + +An L script or program consists of one or more statements. These may +be executable statements, variable or type declarations, or function +or class declarations. Statements outside of functions are said +to be at the C<top level> and are executed in the order they appear, +although you can use a C<return> statement to bail out. +There is no need to have a C<main()> function, but if one is +present, it is executed after all of the top-level statements +(even if you did a C<return> from the top level). + + puts("This is printed first."); + void main() + { + puts("This is printed last."); + } + puts("This is printed second."); + +L statements end in a semi-colon. + + printf("Hello, world\n"); + +Both C style and hash style comments are allowed, but the hash-style +comments are only for the first line and must start on column 1. + + # This is a comment + // So is this + /* And this too */ + # But this is an error (does not start on column 1) + +Whitespace usually is irrelevant. + + printf( + "Hello, world\n") + ; + +... except inside quoted strings: + + # this would print with a linebreak in the middle + print "Hello\ + world"; + +and around the string-concatenation operator " . " so it can +be distinguished from the struct-member selection operator ".". + +Double quotes or single quotes may be used around literal strings: + + puts("Hello, world"); + puts('Hello, world'); + +However, only double quotes "interpolate" variables and handle +character escapes such as for newlines (C<\n>): + + printf("Hello, ${name}\n"); // works fine + printf('Hello, ${name}\n'); // prints ${name}\n literally + +Inside single quotes, you can still escape a line break, the +single quote character (C<\'>), and the escape character (C<\\>). + +If you put a line break in the middle of a string but forget to escape +it, L will complain. + +Adjacent string constants are automatically concatenated, like in C. + + printf("This " "prints " + "the concatenation " + "of ""all"" strings\n"); + +prints "This prints the concatenation of all strings". + +L requires that they be the same "type", all interpolated ("") or +all not interpolated ('') but the dot operator comes the rescue +in this contrived example: + + 'Hi there. ${USER} is ' . "${USER} today"; + +=head1 HTML WITH EMBEDDED L + +For building web-based applications, L has a mode where the input +can be HTML with embedded L code (which we call C<Lhtml>). +This works in a way similar to PHP. +To invoke this mode, the input file must end in .lhtml: + + L [options] home.lhtml + +All text in home.lhtml is passed through to stdout except +that anything between <? and ?> is taken to be one or more +L statements that are replaced by whatever that L code outputs, +and anything between <?= and ?> is taken to be a single L +expression that is replaced by its value. +All L code is compiled at the global scope, so you can include L +variable declarations early in the Lhtml document and reference them +later. + +Here's an example that iterates over an array of key/value pairs +and formats them into a rudimentary table: + + <? key_value_pair row, rows[]; ?> + <html> + <body> + <p>This is a table of data</p> + + <table> + <? rows = get_data(); + foreach (row in rows) { ?> + <tr> + <td><?= row.key ?></td> + <td><?= row.value ?></td> + </tr> + <? } ?> + </table> + + </body> + </html> + +=head1 NAME SCOPING + +Variables must be declared before use, or a compile-time error +will result. However, functions need not be declared before use +although it is good practice to do so. + +Declarations at the top-level code exist at the C<global> scope and +are visible across all scripts executed by a single run of L. You can +qualify a global declaration with C<private> to restrict it to the +current file only; this is similar to a C<static> in C, except that +private globals are not allowed to shadow public globals. Names +declared in a function, or in a block within a function, are C<local> +and are scoped to the block in which they are declared. + +Functions and global variables share the same namespace, so a +variable and function cannot have identical names. Struct tags +have their own namespace, and type names have theirs. + +Inside a function, two locals cannot share the same name, even if they +are in parallel scopes. This is different than C where this is +allowed. But a local can share the same name as a global, in which +case the local is said to C<shadow> the global. + +Names declared inside of a class can be either local or global +depending on how they are qualified. Classes are discussed later. + +=head1 VARIABLES AND TYPES + +L is a strongly typed language with both scalar and complex types. +All variables are typed and must be declared before use. + +The scalar types are int, float, and string. The complex types are +array, hash, struct, and list. L also supports function pointers, +classes, and a special type called C<poly> which matches any type and +normally is used to disable type checking. Finally, L has the concept +of an C<undefined> value which a variable of any type can possess. +These all are discussed next. + +Strong typing means that you can assign something of one type only to +something else of a compatible type. Normally, to be compatible the +types must be structurally the same, but there are exceptions such as +an int being compatible with float and a list sometimes being +compatible with an array or struct. These special cases are discussed +further below. + +An L variable is written as an identifier without any special prefix +characters like in Perl. Variables begin with a letter and can +contains letters, numerals, and underscores, but they B<cannot> begin +with an underscore (_). This is because the L compiler reserves names +starting with _ for internal use. + +A variable declaration includes the +type, the variable name, and optionally an initial value which can +be any L expression: + + int i = 3*2; + + printf("i = %d\n", i); // prints i = 6 + +If an initial value is omitted, the variable starts out with the +undefined value C<undef>, discussed more below. + +=over 4 + +=item Scalars + +A scalar represents a single value that is a string, integer, or +floating-point number. +Strings are wide char (unicode), +integers are arbitrarily large, +and floats are like C's double. + +Examples: + + string animal = "camel"; + int answer = 42; + float pi = 3.14159; + +When one of these types is expected, supplying another one usually is +an error, except that an int always can be used as a float. You can +override this behavior with a type cast, discussed below. + +Hex and octal integer constants are specified like this: + + int space = 0x20; + int escape = 0o33; + +Integer constants can be arbitrarily large; they are not limited +by the machine's word size. + +Strings have a special feature where they can be indexed like arrays, +to get a character or range of characters, or to change a character +(but you cannot change a range of characters): + + string s1, s2; + + s1 = "hello"; + s2 = s1[1]; // s2 gets "e" + s2 = s1[1..3]; // s2 gets "ell" + s1[1] = "x"; // changes s1 to "hxllo" + s1[END+1] = "there"; // changes s1 to "hxllothere" + +The pre-defined identifier C<END> is the index of the last character, +or is -1 if the string is empty. You always can write to one past the end +of a string to append to it, but writing beyond END+1 is an error. + +You delete a character within a string by indexing the string and +setting it to "" (the empty string), or by using the C<undef()> built-in: + + s[3] = ""; // deletes fourth character of s + undef(s[3]); // also deletes fourth character + +=item Undef + +Sometimes you want to signify that a variable has no legal value, such +as when returning an error from a function. L has a read-only pre-defined +constant called C<undef> which you can assign to anything. + + int_var = undef; + array_var = undef; + +This is different than the C<undef()> built-in I<function> which +deletes array, hash, or string elements and which is described +later. + +When used in comparisons, a variable that is undefined is never seen +as true, or as equal to anything defined, so you can easily check for +error conditions: + + unless (f = fopen("file", "r")) { + die("fopen"); + } + while (s = <f>) { + printf("%s\n", s); + } + +And for the cases where it matters, you can test whether something is +undefined with the built-in function C<defined()>: + + ret = myfunc(); + unless (defined(ret)) die("error"); + if (ret != 0) { + printf("myfunc returned %d\n", ret); + } else { + printf("no data from myfunc\n"); + } + +L itself sometimes uses undef to tell you that no value is available. +One case is when you assign to an array element that is more than one +past the end of an array. L auto-extends the array and sets the +unassigned elements to undef. + +Undefinedness is an attribute of a +variable; undefined does not have a value. It may be anything since +the underlying Tcl system "shimmers" variables. If a variable can be +undefined, don't rely on its value until you've checked it first with +C<defined(var)>. + +=item Arrays + +An array holds a list of values, all of the same type: + + string animals[] = { "camel", "llama", "owl" }; + int numbers[] = { 23, 42, 69 }; + +You do not specify a size when declaring an array, because +arrays grow dynamically. + +Arrays are zero-indexed. Here's how you get at elements in an array: + + puts(animals[0]); // prints "camel" + puts(animals[1]); // prints "llama" + +The pre-defined identifier C<END> is the index of the last element +of an array, or is -1 if the array is empty. + + puts(animals[END]); // last element, prints "owl" + +END is valid only inside of an array subscript. + +If you need the length of an array, use a built-in function: + + num_elems = length(animals); // will get 3 + +If the array is empty, length() returns 0. + +To get multiple values from an array, you use what's called an array +C<slice> which is a sub-array of the array being sliced. +Slices are for reading values only, you cannot write to a slice. + + animals[0..1]; // gives { "camel", "llama" } + animals[1..END]; // gives all except the first element + +In this last example where END is used, you must be careful, because if +the array is empty, END will be -1, and an array slice where the +second index is less than the first causes a run-time error. + +You can add and remove from an array with C<push> and C<pop>, +C<unshift> and C<shift>, and C<insert>. +The C<push> and C<pop> functions add and remove from the end: + + string birds[], next; + + push(&birds, "robin"); + push(&birds, "dove", "cardinal", "bluejay"); + next = pop(&birds); // next gets "bluejay" + // birds is now { "robin", "dove", "cardinal" } + +The & means that birds is passed by reference, because it will +be changed. This is discussed more later. + +Another way to append: + + birds[END+1] = "towhee"; + +The C<unshift> and C<shift> functions are similar but they add +and remove from the beginning of the array. + +You can insert anywhere in an array with C<insert>: + + insert(&birds, 2, "crow"); // insert crow before birds[2] + insert(&birds, 3, "hawk", "eagle"); + +In these examples we inserted one or more single elements but +whereever you can put an element you also can splice in a list: + + string new_birds[] = { "chickadee", "turkey" }; + push(&birds, new_birds); // appends chickadee and turkey + +The variable is not required; the constant could have been passed instead. +There is an ambiguity, resolved by the type of the first argument, as to +whether it is two strings being pushed as two new entries in the array, or if +it is a single item being pushed. You have to know the type of the +first argument to know which is which. + +You can remove from anywhere in an array with C<undef>: + + string dev_team[] = { "larry", "curly", "mo" }; + undef(dev_team[0]); // delete "larry" from dev_team + +When you delete an element, all subsequent elements slide down +by one index. Note that undef() works only on a variable; it +cannot remove an element from a function return value, for example. + +You also can directly assign to any array index even if the array +hasn't yet grown up to that index. If you assign more than one past +the current end, the unassigned elements are assigned undef: + + string colors[] = { "blue, "red" }; + colors[3] = "green"; // colors[2] gets undef and colors[3] gets "green" + +You can read from any non-negative array index as well. You will simply +get undef if the element doesn't exist. Reading from a negative index +causes a run-time error. + +An array can hold elements of any type, including other arrays. +Although L does not have true multi-dimensional arrays, arrays of +arrays give you basically the same thing: + + int matrix[][] = { + { 1, 2, 3 }, + { 4, 5, 6 }, + { 7, 8, 9 } + }; + +When declaring an array, it is legal to put the brackets after the +type instead of the name. This is useful in function prototypes that +omit the parameter name, and is required if a function returns an +array. This example illustrates both cases: + + int[] mysort(int[]); + +=item Hashes + +A hash holds a set of key/value pairs: + + int grades{string} = { "Tom"=>85, "Rose"=>90 }; + +When you declare a hash, you specify both the key type (within the {}) +and the value type. The keys must be of scalar type but the values can +be of any type, allowing you to create hashes of arrays or other hashes. + +To get at a hash element, you index the hash with the key: + + grades{"Rose"}; // gives 90 + +If the given key does not exist in the hash, you get back undef. +Using undef as a key causes a run-time error. + +You get a list of all the keys in a hash with the C<keys()> built-in, +which returns an array: + + string students[] = keys(grades); + +Because hashes have no particular internal order, the order in which +the keys ("Tom" and "Rose") appear is undefined. However, you can +obtain a sorted array of keys like this: + + string students[] = sort(keys(grades)); + +The C<length> built-in works on hashes too and returns the number of +key/value pairs. + +You remove an element from a hash with C<undef>: + + undef(grades{"Tom"}); // removes "Tom" from the hash + +It is not an error to remove something that's not in the hash. Note +that undef() works only on a variable; it cannot remove an element +from a function return value, for example. + +When declaring a hash, it is legal to put the braces after the base +type instead of the name. This is useful in function prototypes that +omit the parameter name, and is required is a function returns a +hash. This example illustrates both cases: + + int{string} adjust_grades(int{string}); + +=item Structs + +L structs are much like structs in C. They contain a fixed number +of named things of various types: + + struct my_struct { + int i; + int j; + string s; + }; + struct my_struct st = { 1, 2, "hello" }; + +You index a struct with the "." operator except when it is a +call-by-reference parameter and then you use "->": + + void foo(struct my_struct &byref) { + puts(byref->s); // prints hello + } + puts(st.i); // prints 1 + puts(st.j); // prints 2 + puts(st.s); // prints hello + foo(&st); // pass st by reference + +It is an error to use "." when "->" is required and vice-versa. Be +careful to not put any whitespace around the "." or else you will get +the string concatenation operator and not struct-member selection. + +Structs can be named like C<my_struct> above or they can be anonymous: + + struct { + int i; + int j; + } var1; + +Struct names have their own namespace, so they will never clash with +function, variable, or type names. + +=item Lists + +In the examples above, we have been initializing arrays, hashes, and +structs by putting values inside of {}: + + string nums[] = { "one", "two", "three" }; + +In L, the C<{}> is an operator that creates a C<list> and can be used +anywhere an expression is valid. The array could instead be +initialized like this: + + string nums[]; + nums = { "one", "two", "three" }; + +We said before that you can assign a value to something only if it has +a compatible type. Lists are special in that they can be compatible +with arrays, hashes, and structs. A list where all the elements are +of the same type, say T, is compatible with an array of things of +type T. The example above illustrates this. + +A list also is compatible with a struct if the list elements agree +in type and number with the struct. The assignment of the variable +C<st> above illustrates this. + +A list is compatible with a hash if it has a sequence of key/value +pairs and they are all compatible with the key/value types of +the hash: + + int myhash{string} = { "one"=>1, "two"=>2, "three"=>3 }; + +Lists are very useful at times because you can use them to build up +larger complex structures. To concatenate two arrays, you could do +this: + + { (expand)array1, (expand)array2 }; + +The (expand) operator takes an array (or struct or list) and moves its +elements out a level as if they were between the { and } separated by +commas. This is discussed more later. + +=item Poly + +Sometimes you don't want L to do type checking. +In this case, you use the C<poly> type, which is compatible with +any type. Poly effectively disables type checking, allowing you +to use or assign values without regard to their types. Obviously, +care must be taken when using poly. + +The B<-poly> option to L causes all variables to be treated as if they +were of type poly, regardless of how they are declared. + +=item Type Casts + +Something of one type can be converted into something of another +type with a type cast like in C: + + string_var = (string)13; + +If the thing being cast cannot be converted to the requested type, the +result of the cast is C<undef>. + +=item Typedefs + +You can declare a type name to be a short hand for another type, as +you would in C: + + typedef int index_t; + typedef string table_t{index_t}; + +And then use the short-hand as you would any other type name: + + table_t my_table; + my_table{3} = "value"; + +You can typedef a function pointer too. This declares compar_t +as type function that takes two ints and returns an int: + + typedef int compar_t(int a, int b); + +Type names belong to their own namespace, so you can define a typedef +with the same name as a variable, function, or struct name without +ambiguity. + +=back + +=head1 INTERPOLATION + +Expressions can be interpolated into double-quoted strings, which +means that within a string you can write an expression and at run-time +its value will be inserted. For example, this interpolates two +variables: + + int a = 12; + string b = "hello"; + + /* This will print "A is 12 and b is hello". */ + + printf("A is ${a} and b is ${b}\n"); + +Everything inside the ${} is evaluated like any other L expression, so +it is not limited to just variables: + + printf("The time is ${`date`}\n"); + +=head1 FUNCTIONS + +L's functions are much like functions in C. Like variable names, +function names B<cannot> begin with an underscore (_). + +Each function must be declared with a return type and a +formal-parameter list: + + int sum(int a, int b) + { + return (a + b); + } + +C<void> is a legal return type for a function that returns no value. +Functions cannot be nested. + +Function prototypes are allowed, where all but the function body is +declared. In a prototype, you can omit any parameter names or use +C<void> for an empty parameter list: + + void no_op1(void); + void no_op2(); + int sum(int, int); + +Unlike Perl, when calling a function you must use parentheses around +the arguments: + + sum(a, b); + +L does a special kind of call called a C<pattern function> call +when the function name is capitalized and contains an underscore; +these are useful for calling Tcl commands and are described later. +Normal function names should avoid being both capitalized and +with an underscore. + +Parameters are passed by value by default. To pass by reference, +you use a C<&> in the declaration and in the function call: + + void inc(int &arg) + { + ++arg; + } + + inc(&x); // inc() can change x + +The C<&> only tells L to pass by reference. It is not a pointer. +You use a reference to give the called function the ability to change +the caller's variable. + +Only variables can be passed by reference, not elements of arrays, +hashes, or structs. This is one significant difference from C. +Passing an array, hash, or struct element with C<&> uses C<copy in/out>, +not a true reference. The element value is copied +into a temp variable and the temp is passed by reference. Then when +the function returns, any changes to the temp are copied back into the +array, hash, or struct element. In most cases this behaves like +call-by-reference and you don't need to worry about it. +But if you access the passed element during the function call, +by referencing it directly instead of through the formal parameter, +then you must be careful: + + string array[] = { "one", "two" }; + void fn(string &var, string val) + { + var = val; + array[0] = "this gets overwritten by the copy-out"; + } + void main() + { + fn(&array[0], "new"); + puts(array[0]); // will print "new" + } + +Instead of passing a reference, you can pass C<undef> like you would a +NULL pointer in C. +You test for this with the C<defined()> operator: + + void inc(int &arg) + { + if (defined(&arg)) ++arg; + } + + inc(undef); // does nothing + inc(&x); // increments x + +If you pass C<undef> as a reference and then attempt to access +the parameter, a run-time error results similar to derefencing +a NULL pointer in C. + +When accessing a struct argument inside a function, if the struct was +passed by reference, the "->" operator must be used instead of ".". +This makes it clear to the reader that the struct variable is passed +by reference; it is intended to allude to a C pointer even though L +does not have pointers. + +Functions can take a variable number of arguments, like printf does. +In the function declaration, you use the qualifier "..." in front +of the last formal parameter name and omit its type: + + void dump(...args) + { + string s; + foreach(s in args) puts(s); + } + dump("just one"); + dump("but two", "or three", "or more is OK"); + +Inside the function, C<args> has type array of poly, allowing any +number of parameters of any type to be passed. + +=head2 The main() Function + +If main() is present, it is called after all of the top-level statements +have executed. The main() function may defined in any of the following +ways: + + void|int main() {} + void|int main(string argv[]) {} + void|int main(int argc, string argv[]) {} + void|int main(int argc, string argv[], string env{string}) {} + +The C<argv> array is populated from the script name and any arguments +that appear after the name on the L command line. +In this example, argc is 4 and argv[] contains "script.l", "arg1", +"arg2", and "arg3": + + L script.l arg1 arg2 arg3 + +The C<env> hash is populated with the environment variables present +when L is invoked. Although you can change this hash, writes to it +are not reflected back into the environment. To do that use the +C<putenv> library function. + +Only a C<main> written in L is automatically called. +You can write a C<main> in Tcl but L will not call it automatically. + +If C<main> is declared to have return type C<int> and it returns +a non-zero value, L will exit with an exit status equal to +the return value. + +=head2 Function Pointers + +Function pointers are supported, but only as arguments -- you cannot +otherwise assign a function pointer to a variable. It is common to +first typedef the function-pointer type; here is one for a function +that compares two strings: + + typedef int str_compar_t(string a, string b); + +You can then pass such a compare function as follows: + + string a[]; + + bubble_sort(a, &unary_compar); + +Where the sort function looks like this: + + string[] bubble_sort(string a[], str_compar_t &compar) + { + do { + ... + if (compar(a[i], a[i+1] > 0) { ... } + ... + } ... + } + +And the compare function looks like this: + + int unary_compar(string a, string b) + { + int al = length(a); + int bl = length(b); + + if (al < bl) { + return -1; + } else if (al > bl) { + return 1; + } else { + return 0; + } + } + +=head1 CONTROL TRANSFER STATEMENTS + +L has most of the usual conditional and looping constructs. + +A variable of any type will evaluate to false if it is undefined. +An int or a float with a value of 0 is also false. +All other values are true. + + int undefined = undef; + int zero = 0; + int one = 1; + + if (undefined) // false + if (zero) // false + if (one) // true + if (defined(zero)) // true + +See the list of operators in the next section for information on +comparison and logic operators, which are commonly used in conditional +statements. + +=over 2 + +=item if + +The C<if> statement comes in the traditional form: + + if ( condition ) { + ... + } else if ( other condition ) { + ... + } else { + ... + } + +And there's a negated version of it provided as a more readable +version of C<if (!I<condition>)>. + + unless ( condition ) { + ... + } + +=item while + + while ( condition ) { + ... + } + + do { + ... + } while ( condition ) + +=item for + + for (i = 0; i < max; ++i) { + ... + } + +=item foreach + +The C<foreach> statement lets you iterate through the elements of an +array: + + string element; + string myarray[]; + + foreach (element in myarray) { + printf("This element is %s\n", element); + } + +... of a hash: + + string key; + int value; + int myhash{string}; + + foreach (key=>value in myhash) { + printf("Key %s has value %d\n", key, value); + } + +... or of a string: + + string char; + + foreach (char in mystring) { + printf("This char is %s\n", char); + } + +... or through the lines in a string: + + int i = 0; + string s, lines; + + foreach (s in <lines>) { + puts("line #${++i}: ${s}"); + } + +Inside the loop, the index variable(s) (C<element>, C<key>, C<val>, and +C<char> above) get I<copies> of the iterated elements, so +if you assign to them, the thing you're iterating over does not change. + +If you want to stride through more than one array element, character, +or line in each iteration, just use a list of value variables instead of one: + + foreach (e1,e2,e3 in myarray) { + printf("Next three are %s:%s:%s\n", e1, e2, e3); + } + +If there isn't a multiple of three things to iterate through, the +stragglers get undef on the last iteration. Strides +work only for arrays and strings, not hashes. + +After completing the loop and falling through, all loop counters +become undefined (they get the C<undef> value). If the loop +is prematurely ended with a C<break> or by jumping out of the +loop with a C<goto>, the loop counters keep their values. + +=item switch + +The C<switch> statement is like C's except that regular expressions +can be used as case expressions: + + switch (string_var) { + case /[0-9]+/: + puts("numeric"); + break; + case /[a-zA-Z][0-9a-zA-Z]*/: + puts("alphanumeric"); + break; + default: + puts("neither"); + break; + } + +The default case is optional. The expression being switched on +must be of type integer, string or poly. + +In addition to checking the value of the switch expression, +you can test whether it is undefined. +This is useful when switching on a function return value +which could be C<undef> to signal an error condition. + + switch (myfunc(arg)) { + case /OK/: + puts("all is A-OK"); + break; + case undef: + puts("error"); + break; + default: + puts("unknown return value"); + break; + } + +To avoid confusion, the alternate regular-expression-delimiter syntax +is restricted: + + switch (str) { + case m|x*y|: // "|" and most other punctuation as the delim -- ok + // except ( and : -- error + // and any alphabetic character -- error + break; + case m: // is the variable m (not a regexp) -- ok + break; + case mvar: // and variables starting with "m" -- ok + break; + } + +=item break and continue + +L has C<break> and C<continue> statements that behave like C's. +They work in all L loops including C<foreach> loops, and C<break> works +in C<switch> case bodies. + +=item goto + +The C<goto> statement unconditionally transfers control to a label in +the same function, or to a label at the global scope if the goto is at +the global scope.

You +can use any identifier you want as the delimiter, it doesn't have +to be END. +A semicolon after the END is optional. + +The text inside the here document undergoes interpolation and escape +processing. +If you don't want that, put the initial delimiter inside of single +quotes: + + string s = <<'END' + None of this text is interpolated. + So this ${xyz} appears literally as '${xyz}'. + And so does \ and ' and " and anything else. + END; + +To help readability, you can indent your here document but have +the indenting white space ignored. +Put the initial delimiter on the next line and then +whatever whitespace you put before it gets ignored: + + string s = + <<END + This is the first line in s and gets no leading white space. + This line ends up with a single leading space. + And this ends up with two. + END; + +Exceptions to the indentation rule: +a blank line is processed as if it is indented, +and the end delimiter can have any amount of leading white space +so that you can indent it differently. + +=head1 WORKING WITH TCL/TK + +L is built on top of Tcl: L functions are compiled down to Tcl procs, +L local variables are just Tcl variables local to the proc, and L global +variables are Tcl globals. +Although L is designed to hide its Tcl underpinnings, sometimes it is +useful for L and Tcl to cooperate. + +=head2 Mixing L and Tcl Code + +When you invoke L with a script whose name ends in C<.l>, the script +must contain only L code. +If you run a C<.tcl> script, you can mix L and Tcl: + + puts "This is Tcl code" + #lang L + printf("This is L code\n"); + #lang tcl + puts "Back to Tcl code" + +You also can run L code from within Tcl by passing the L code to the +Tcl command named C<L>: + + puts "Tcl code again" + L { printf("Called from the L Tcl command.\n"); } + +=head2 Calling Tcl from L + +You call a Tcl proc from L like you would an L function: + + string s = "hello world"; + puts(s); + +In this example, C<puts> is the Tcl command that outputs its argument +to the C<stdout> channel. + +If you want argument type checking, you can provide a prototype for the Tcl +functions you call. Otherwise, no type checking is performed. + +In Tcl, options usually are passed as strings like "-option1" or "-option2". +L has a feature to pass these options more pleasantly: + + func(option1:); // passes "-option1" + func(option2: value, arg); // passes "-option2", value, arg + +Without this, you would have to say: + + func("-option1"); + func("-option2", value, arg); + +A similar feature is for passing sub-commands to Tcl commands: + + String_length("xyzzy"); // like Tcl's [string length xyzzy] + String_isSpace(s); // like Tcl's [string is space $s] + +Whenever the function name is capitalized and contains an underscore, +the sequence of capitalized names after the underscore are converted +to (lower case) arguments (although capitalizing the +first name after the underscore is optional). +This is called a C<pattern function> call. + +A pattern-function call often is used to call a Tcl proc, but you +can call an L function just as easily, and L has a special case +when the function is named like C<Myfunc_*>: + + void Myfunc_*(...args) + { + poly p; + + printf("Myfunc_%s called with:\n", $1); + foreach (p in args) printf("%s\n", p); + } + void main() + { + Myfunc_cmd1(1); + Myfunc_cmd2(3,4,5); + } + +If C<Myfunc_*> is declared, then any call like C<Myfunc_x> becomes a +call to C<Myfunc_*> where the string C<x> is put into the local +variable C<$1> inside C<Myfunc_*>. The remaining parameters are +handled normally. +This gives you a way to handle a collection of sub-commands without +having to declare each as a separate L function. +Note that this use of C<$1> clashes with regular expression captures +(described later), so if you use both, you should save off C<$1> +before using any such regular expressions. + +If you need to execute arbitrary Tcl code rather than just call a proc, +you pass it to Tcl's C<eval> command: + + eval("puts {you guessed it, Tcl code again}"); + +=head2 Calling L from Tcl + +L functions are easily called from Tcl, because an L function +C<foo> compiles down to a Tcl proc named C<foo> in the global +namespace. +Let's say this is run from a script named C<script.tcl>: + + #lang L + int avg(...args) + { + int i, sum=0; + unless (length(args)) return (0); + foreach (i in args) sum += i; + return (sum/length(args)); + } + #lang tcl + set x [avg 4 5 6] + puts "The average is $x" + +The L code defines a proc named C<avg> which the Tcl code then calls. + +An exception is that C<private> L functions are not callable from Tcl. + +=head2 Variables + +Because L variables are just Tcl variables, you can access L variables +from Tcl code. Here is an example from the L library: + + int size(string path) + { + int sz; + + if (catch("set sz [file size $path]")) { + return (-1); + } else { + return (sz); + } + } + +In this Tcl code, C<$path> refers to the L formal parameter C<path>, +and the L local C<sz> is set to the file size. This example also +illustrates how you can use Tcl's exception-handling facility +to catch an exception raised within some Tcl code. + +An exception is that private L global names are mangled (to +make them unique per-file). +You can pass the mangled name to Tcl code with the C<&> operator. +Here we are passing the name of the private function C<mycallback> to +register a Tcl fileevent "readable" handler: + + private void mycallback(FILE f) { ... } + + fileevent(f, "readable", {&mycallback, f}); + +=head2 Complex variables + +Passing scalar variables works because they have the same representation +in L and in Tcl. + +Passing complex variables is trickier and is not supported, but if you +want to try here is what you need to know. This is subject to change. +An L array is a Tcl list. +An L struct is a Tcl list with the first struct member as the first +list element and so on. +An L hash table is a Tcl dict. +If an L variable is deeply nested, so is the Tcl variable. + +So long as you understand that and do the appropriate thing in both +languages, passing complex variables usually is possible. + +=head2 Namespaces + +You can access Tcl procs and variables in namespaces other than +the global namespace by qualifying the name: + + extern string ::mynamespace::myvar; + + /* Print a bytecode disassembly of the proc "foo". */ + puts(::tcl::unsupported::disassemble("proc", "foo")); + + /* Print a variable in another namespace. */ + puts(::mynamespace::myvar); + +=head2 Calling Tk + +To help call Tk widgets, L has a C<widget> type that is used with the +pattern function calls described above. A widget value behaves like +a string except in a pattern function call where it is the name +of the widget to call: + + widget w = Text_new(); + Text_insert(w, "end", "hi!"); // like Tcl's $w insert end hi! + +Another feature is useful for calling Tk widgets that take the I<name> +of a variable whose value is updated when the user changes a widget +field. You can use an L variable like this: + + string msg; + ttk::label(".foo", textvariable: &msg); + +The ampersand (&) in front of C<msg> alludes to a C pointer but it +really passes just the name of the variable. L does this when the +option name ends in "variable", as "textvariable" does in the example +above (yes, this is a hack). + +You can do this with globals, class variables, or class instance +variables, and only with a variable and not an array, structure, or +hash element. + +=head1 OPERATORS + +=over 4 + +=item Arithmetic + + + addition + - subtraction + * multiplication + / division + % remainder + +=item Numeric and String comparison + + == equality + != inequality + < less than + > greater than + <= less than or equal + >= greater than or equal + +=item String comparison + + =~ regexp match or substitute + !~ negated regexp match + +=item Comparison of composite types (array, hash, struct) + + eq(a,b) + +=item Bit operations + + & bit and + | bit or + ^ bit exclusive or + ~ bit complement + << left shift + >> right shift + +=item Boolean logic + + && and + || or + ! not + +=item Conditional + + ?: ternary conditional (as in C) + +=item Indexing + + [] array index + {} hash index + . struct index (no whitespace around the dot) + -> struct index (call-by-reference parameters dereference) + -> class and instance variable access (object dereference) + +=item Miscellaneous + + = assignment + , statement sequence + . string concatenation (must have whitespace around the dot) + `` command expansion + +=item Assignment + + +=, -=, *=, /=, %=, &=, |=, ^=, <<=, >>=, .= + +=item Operator precedence (highest to lowest) and associativity + + `` (non assoc) + [] {} .

Class variables are associated with the class +and not the individual objects that you allocate, so there is only one +copy of each. Instance variables get attached to each object. + + class myclass + { + /* Class variables. */ + public string pub_var; + private int num = 0; + + /* Instance variables. */ + instance { + public string inst_var; + private int n; + } + ... + } + +All declarations (except the constructors and destructors) must be +qualified with either C<public> or C<private> to say whether the name +is visible at the global scope or only inside the class. + +A class can have one or more constructors and destructors but they are optional. +Inside a constructor, the variable C<self> is automatically declared +as the object being constructed. A constructor should return +C<self>, although it also could return C<undef> to signal an error. +A destructor must be declared with C<self> as the first parameter. + + constructor myclass_new() + { + n = num++; + return (self); + } + destructor myclass_delete(myclass self) {} + +If omitted, L creates a default constructor or destructor named +C<classname_new> and C<classname_delete>. Although not shown in this +example, you can declare them with any number of parameters, just like +regular functions. + +A C<public> class member function is visible at the global scope, so +its name must not clash with any other global function or variable. A +private member function is local to the class. + +The first parameter to each public function must be C<self>, the +object being operated on. Private functions do not explicitly include +C<self> in the parameter list because it is implicitly passed by the +compiler. + + private void bump_num() + { + ++n; + } + public int myclass_getnum(myclass self) + { + bump_num(); + return (n); + } + +To create an object, you must call a constructor, because just +declaring the variable does not allocate anything: + + myclass obj; + + obj = myclass_new(); + +To operate on an object, you call one of its public member functions, +passing the object as the first argument: + + int n = myclass_getnum(obj); + +L allows you to directly access public class and instance variables +from outside the class. To get a class variable, you dereference the +class name (you must use ->): + + string s = myclass->pub_var; + +To get a public instance variable, you dereference the object whose +data you want to access: + + string s = obj->inst_var; + +Once you free an object + + myclass_delete(obj); + +you must be careful to not use C<obj> again unless you assign a +new object to it, or else a run-time error will result. + +=head1 DEBUGGING + +=head2 Function Tracing + +L function tracing is controlled with #pragma statements, _attribute +clauses in function declarations, command-line options, +environment variables, and a run-time API. +When a function is marked for tracing, +by default its entry and exit are traced to stderr, +but you can use your own custom hooks +to do anything you want. + +A #pragma takes a comma-separated list of attribute assignments: + + #pragma fntrace=on + string myfunc(int arg) + { + return("return value"); + } + void main() + { + myfunc(123); + } + +When this program runs, traces go to stderr with a millisecond +timestamp, the function name, parameter values, and return value: + + 1: enter main + 1: enter myfunc: '123' + 2: exit myfunc: '123' ret 'return value' + 3: exit main + +The allowable tracing attributes are as follows. + +=over 4 + +=item B<fntrace=on | entry | exit | off> + +Enable tracing on both function entry and exit, entry only, exit only, +or disable tracing altogether. + +=item B<trace_depth=n> + +Trace only to a maximum call depth of n. + +=item B<fnhook=myhook> + +Use myhook as the trace hook (see below). + +=back + +A #pragma stays in effect until overridden by another #pragma or by +an _attribute clause in a function declaration which provides +per-function tracing control: + + void myfunc2(int arg) _attribute (fntrace=off) // don't trace this one + { + } + +Tracing also can be controlled with command-line options: + +=over 4 + +=item B<--fntrace = <on | entry | exit | off>> + +Enable tracing of all functions on both function entry and exit, entry +only, exit only, or disable all tracing. +This overrides any #pragma or _attribute clauses in the program. + +=item B<--trace-out=stdin | stderr | filename | host:port> + +Send default trace output to stdin, stderr, a file, or a TCP socket. + +=item B<--trace-files=colon-separated list of glob | /regexp/> + +Enable tracing of all functions in the given files, specified +either as globs or regular expressions. +A + before a glob or regexp enables tracing, a - disables, and no ++ or - is like having a +, except that +the leading one is special: if omitted, +it means trace exactly what is specified, +overriding any #pragmas or _attribute clauses in the code, +by first removing all traces and then processing the file list. + +=item B<--trace-funcs=colon-separated list of glob | /regexp/> + +Like trace-files but specifies functions. + +=item B<--fnhook=myhook> + +Use C<myhook> as the trace hook, overriding any #pragmas in the program. + +=item B<--trace-script=script.l | <L code>> + +Get the trace hook from a file, or use the given L code (see below). + +=back + +Some examples: + + # Trace all functions + $ L --fntrace=on myscript.l + + # Trace only foo + $ L --trace-funcs=foo myscript.l + + # Trace foo in addition to what the source marks for tracing + $ L --trace-funcs=+foo myscript.l + + # Trace all functions except foo + $ L --trace-funcs=*:-foo myscript.l + # This does it too + $ L --fntrace=on --trace-funcs=-foo myscript.l + +Environment variables also can control tracing and take precedence +over the other ways above: + + L_TRACE_ALL=on | entry | exit | off + L_TRACE_OUT=stdin | stderr | filename | host:port + L_TRACE_FILES=colon-separated list of glob | /regexp/ + L_TRACE_FUNCS=colon-separated list of glob | /regexp/ + L_TRACE_DEPTH=n + L_TRACE_HOOK=myhook + L_TRACE_SCRIPT=script.l | <L code> + +Things in L_TRACE_FUNCS are applied after things in L_TRACE_FILES. +As with the command-line options, they also can begin with + or - to +add or subtract from what is specified elsewhere. + +As a short-cut, + + L_TRACE=stdin | stderr | filename | host:port + +traces all functions and sets the trace output location. + +More examples: + + # Trace all files except foo.l + L_TRACE_FILE=*:-foo.l L myscript.l + + # Trace main() and buggy() in addition to whatever is marked + # for tracing with #pragmas or _attribute clauses in the code. + L_TRACE_FUNCS=+main:buggy L myscript.l + + # Trace *only* main() and buggy(). + L_TRACE_FUNCS=main:buggy L myscript.l + +There also is a run-time API that takes a hash of named arguments +analogous to those above: + + Ltrace({ "fntrace" => "on", + "fnhook_out" => "myhook", + "trace_depth" => 3, + "trace_out" => "tracing.out", + "trace_files" => "foo.l", + "trace_funcs" => "+main:buggy" }); + +To use your own tracing function, specify C<fnhook> in any of the +above ways. +Your hook is called on function entry and exit instead of +the default hook. +Its prototype must look like this: + + void myhook(int pre, poly argv[], poly ret); + +where pre is 1 when your hook is called upon function entry and 0 when +called upon exit, argv contains the function's arguments +(argv[0] is the function name; argv[1] is the first +parameter), and ret is the return value (exit hook only; it is undef +for entry). + +If you use your own hook and then want to go back to the default, +set C<fnhook=def>. + +To avoid infinite recursion, during the call of a hook, further calls +into the hook are disabled. Also, functions defined as hooks, and the +L library functions, are not traced. + +The trace-script attribute is a useful way to provide your own hook: + + L_TRACE_SCRIPT=my-trace-hook.l // filename must end in .l + L_TRACE_SCRIPT=<L code> + +In the latter case, the L code gets wrapped in a function like this: + + void L_fn_hook(int pre, poly av[], poly ret) + { + ...code from L_TRACE_SCRIPT... + } + +and C<L_fn_hook> is used as the default trace hook. + +As one example of where this is useful: say you are trying to find +whether the function C<foo> is ever called with the first argument of 123, +and if so, to print all the arguments: + + L_TRACE_FUNCS=foo L_TRACE_SCRIPT='if (av[0]==123) puts(av)' L myscript.l + +=head1 EXAMPLE CODE + +=head2 shapes.l + +This is something we hand to our customers to see what "shape" +their source trees have. + + #!/usr/bin/bk tclsh + /* + * Determine the files/size of each directory under a bk repository. + * Optionally transform the directory names to obscure their structure. + * + * The idea is that you can run this script like this: + * + * bk tclsh shapes.l <path_to_root_of_repo> + * + * and get a list of directories with their sizes and number of files in + * each of them.

The resulting *roff code is suitable for display on a +terminal using nroff(1), normally via man(1), or printing using troff(1). + +I<input> is the file to read for POD source (the POD can be embedded in +code). If I<input> isn't given, it defaults to STDIN. I<output>, if given, +is the file to which to write the formatted output. If I<output> isn't +given, the formatted output is written to STDOUT. Several POD files can be +processed in the same B<pod2man> invocation (saving module load and compile +times) by providing multiple pairs of I<input> and I<output> files on the +command line. + +B<--section>, B<--release>, B<--center>, B<--date>, and B<--official> can be +used to set the headers and footers to use; if not given, Pod::Man will +assume various defaults. See below or L<Pod::Man> for details. + +B<pod2man> assumes that your *roff formatters have a fixed-width font named +CW. If yours is called something else (like CR), use B<--fixed> to specify +it. This generally only matters for troff output for printing. Similarly, +you can set the fonts used for bold, italic, and bold italic fixed-width +output. + +Besides the obvious pod conversions, Pod::Man, and therefore pod2man also +takes care of formatting func(), func(n), and simple variable references +like $foo or @bar so you don't have to use code escapes for them; complex +expressions like C<$fred{'stuff'}> will still need to be escaped, though. +It also translates dashes that aren't used as hyphens into en dashes, makes +long dashes--like this--into proper em dashes, fixes "paired quotes," and +takes care of several other troff-specific tweaks. See L<Pod::Man> for +complete information. + +=head1 OPTIONS + +=over 4 + +=item B<-c> I<string>, B<--center>=I<string> + +Sets the centered page header to I<string>. The default is "User +Contributed Perl Documentation", but also see B<--official> below. + +=item B<-d> I<string>, B<--date>=I<string> + +Set the left-hand footer string to this value. By default, the modification +date of the input file will be used, or the current date if input comes from +STDIN. + +=item B<--fixed>=I<font> + +The fixed-width font to use for vertabim text and code. Defaults to CW. +Some systems may want CR instead. Only matters for troff(1) output. + +=item B<--fixedbold>=I<font> + +Bold version of the fixed-width font. Defaults to CB. Only matters for +troff(1) output. + +=item B<--fixeditalic>=I<font> + +Italic version of the fixed-width font (actually, something of a misnomer, +since most fixed-width fonts only have an oblique version, not an italic +version). Defaults to CI. Only matters for troff(1) output. + +=item B<--fixedbolditalic>=I<font> + +Bold italic (probably actually oblique) version of the fixed-width font. +Pod::Man doesn't assume you have this, and defaults to CB.

Without this option, the manual +name is set to the uppercased base name of the file being converted unless +the manual section is 3, in which case the path is parsed to see if it is a +Perl module path. If it is, a path like C<.../lib/Pod/Man.pm> is converted +into a name like C<Pod::Man>. This option, if given, overrides any +automatic determination of the name. + +Note that this option is probably not useful when converting multiple POD +files at once. The convention for Unix man pages for commands is for the +man page title to be in all-uppercase even if the command isn't. + +=item B<-o>, B<--official> + +Set the default header to indicate that this page is part of the standard +Perl release, if B<--center> is not also given. + +=item B<-q> I<quotes>, B<--quotes>=I<quotes> + +Sets the quote marks used to surround CE<lt>> text to I<quotes>. If +I<quotes> is a single character, it is used as both the left and right +quote; if I<quotes> is two characters, the first character is used as the +left quote and the second as the right quoted; and if I<quotes> is four +characters, the first two are used as the left quote and the second two as +the right quote. + +I<quotes> may also be set to the special value C<none>, in which case no +quote marks are added around CE<lt>> text (but the font is still changed for +troff output). + +=item B<-r>, B<--release> + +Set the centered footer. By default, this is the version of Perl you run +B<pod2man> under. Note that some system an macro sets assume that the +centered footer will be a modification date and will prepend something like +"Last modified: "; if this is the case, you may want to set B<--release> to +the last modified date and B<--date> to the version number. + +=item B<-s>, B<--section> + +Set the section for the C<.TH> macro. The standard section numbering +convention is to use 1 for user commands, 2 for system calls, 3 for +functions, 4 for devices, 5 for file formats, 6 for games, 7 for +miscellaneous information, and 8 for administrator commands. There is a lot +of variation here, however; some systems (like Solaris) use 4 for file +formats, 5 for miscellaneous information, and 7 for devices. Still others +use 1m instead of 8, or some mix of both. About the only section numbers +that are reliably consistent are 1, 2, and 3. + +By default, section 1 will be used unless the file ends in .pm in which case +section 3 will be selected. + +=item B<-v>, B<--verbose> + +Print out the name of each output file as it is being generated. + +=back + +=head1 DIAGNOSTICS + +If B<pod2man> fails with errors, see L<Pod::Man> and L<Pod::Parser> for +information about what those errors might mean. + +=head1 EXAMPLES + + pod2man program > program.1 + pod2man SomeModule.pm /usr/perl/man/man3/SomeModule.3 + pod2man --section=7 note.pod > note.7 + +If you would like to print out a lot of man page continuously, you probably +want to set the C and D registers to set contiguous page numbering and +even/odd paging, at least on some versions of man(7). + + troff -man -rC1 -rD1 perl.1 perldata.1 perlsyn.1 ... + +To get index entries on stderr, turn on the F register, as in: + + troff -man -rF1 perl.1 + +The indexing merely outputs messages via C<.tm> for each major page, +section, subsection, item, and any C<XE<lt>E<gt>> directives. See +L<Pod::Man> for more details. + +=head1 BUGS + +Lots of this documentation is duplicated from L<Pod::Man>. + +=head1 NOTES + +For those not sure of the proper layout of a man page, here are some notes +on writing a proper man page. + +The name of the program being documented is conventionally written in bold +(using BE<lt>E<gt>) wherever it occurs, as are all program options. +Arguments should be written in italics (IE<lt>E<gt>). Functions are +traditionally written in italics; if you write a function as function(), +Pod::Man will take care of this for you. Literal code or commands should +be in CE<lt>E<gt>. References to other man pages should be in the form +C<manpage(section)>, and Pod::Man will automatically format those +appropriately. As an exception, it's traditional not to use this form when +referring to module documentation; use C<LE<lt>Module::NameE<gt>> instead. + +References to other programs or functions are normally in the form of man +page references so that cross-referencing tools can provide the user with +links and the like. It's possible to overdo this, though, so be careful not +to clutter your documentation with too much markup. + +The major headers should be set out using a C<=head1> directive, and are +historically written in the rather startling ALL UPPER CASE format, although +this is not mandatory. Minor headers may be included using C<=head2>, and +are typically in mixed case. + +The standard sections of a manual page are: + +=over 4 + +=item NAME + +Mandatory section; should be a comma-separated list of programs or functions +documented by this podpage, such as: + + foo, bar - programs to do something + +Manual page indexers are often extremely picky about the format of this +section, so don't put anything in it except this line. A single dash, and +only a single dash, should separate the list of programs or functions from +the description. Functions should not be qualified with C<()> or the like. +The description should ideally fit on a single line, even if a man program +replaces the dash with a few tabs. + +=item SYNOPSIS + +A short usage summary for programs and functions. This section is mandatory +for section 3 pages. + +=item DESCRIPTION + +Extended description and discussion of the program or functions, or the body +of the documentation for man pages that document something else. If +particularly long, it's a good idea to break this up into subsections +C<=head2> directives like: + + =head2 Normal Usage + + =head2 Advanced Features + + =head2 Writing Configuration Files + +or whatever is appropriate for your documentation. + +=item OPTIONS + +Detailed description of each of the command-line options taken by the +program. This should be separate from the description for the use of things +like L<Pod::Usage|Pod::Usage>. This is normally presented as a list, with +each option as a separate C<=item>. The specific option string should be +enclosed in BE<lt>E<gt>. Any values that the option takes should be +enclosed in IE<lt>E<gt>. For example, the section for the option +B<--section>=I<manext> would be introduced with: + + =item B<--section>=I<manext> + +Synonymous options (like both the short and long forms) are separated by a +comma and a space on the same C<=item> line, or optionally listed as their +own item with a reference to the canonical name. For example, since +B<--section> can also be written as B<-s>, the above would be: + + =item B<-s> I<manext>, B<--section>=I<manext> + +(Writing the short option first is arguably easier to read, since the long +option is long enough to draw the eye to it anyway and the short option can +otherwise get lost in visual noise.) + +=item RETURN VALUE + +What the program or function returns, if successful. This section can be +omitted for programs whose precise exit codes aren't important, provided +they return 0 on success as is standard. It should always be present for +functions. + +=item ERRORS + +Exceptions, error return codes, exit statuses, and errno settings. +Typically used for function documentation; program documentation uses +DIAGNOSTICS instead. The general rule of thumb is that errors printed to +STDOUT or STDERR and intended for the end user are documented in DIAGNOSTICS +while errors passed internal to the calling program and intended for other +programmers are documented in ERRORS. When documenting a function that sets +errno, a full list of the possible errno values should be given here. + +=item DIAGNOSTICS + +All possible messages the program can print out--and what they mean. You +may wish to follow the same documentation style as the Perl documentation; +see perldiag(1) for more details (and look at the POD source as well). + +If applicable, please include details on what the user should do to correct +the error; documenting an error as indicating "the input buffer is too +small" without telling the user how to increase the size of the input buffer +(or at least telling them that it isn't possible) aren't very useful. + +=item EXAMPLES + +Give some example uses of the program or function. Don't skimp; users often +find this the most useful part of the documentation. The examples are +generally given as verbatim paragraphs. + +Don't just present an example without explaining what it does. Adding a +short paragraph saying what the example will do can increase the value of +the example immensely. + +=item ENVIRONMENT + +Environment variables that the program cares about, normally presented as a +list using C<=over>, C<=item>, and C<=back>. For example: + + =over 6 + + =item HOME + + Used to determine the user's home directory. F<.foorc> in this + directory is read for configuration details, if it exists. + + =back + +Since environment variables are normally in all uppercase, no additional +special formatting is generally needed; they're glaring enough as it is. + +=item FILES + +All files used by the program or function, normally presented as a list, and +what it uses them for. File names should be enclosed in FE<lt>E<gt>. It's +particularly important to document files that will be potentially modified. + +=item CAVEATS + +Things to take special care with, sometimes called WARNINGS. + +=item BUGS + +Things that are broken or just don't work quite right. + +=item RESTRICTIONS + +Bugs you don't plan to fix. :-) + +=item NOTES + +Miscellaneous commentary. + +=item SEE ALSO + +Other man pages to check out, like man(1), man(7), makewhatis(8), or +catman(8). Normally a simple list of man pages separated by commas, or a +paragraph giving the name of a reference work. Man page references, if they +use the standard C<name(section)> form, don't have to be enclosed in +LE<lt>E<gt> (although it's recommended), but other things in this section +probably should be when appropriate. + +If the package has a mailing list, include a URL or subscription +instructions here. + +If the package has a web site, include a URL here. + +=item AUTHOR + +Who wrote it (use AUTHORS for multiple people). Including your current +e-mail address (or some e-mail address to which bug reports should be sent) +so that users have a way of contacting you is a good idea. Remember that +program documentation tends to roam the wild for far longer than you expect +and pick an e-mail address that's likely to last if possible. + +=item COPYRIGHT AND LICENSE + +For copyright + + Copyright YEAR(s) by YOUR NAME(s) + +(No, (C) is not needed. No, "all rights reserved" is not needed.) + +For licensing the easiest way is to use the same licensing as Perl itself: + + This library is free software; you may redistribute it and/or modify + it under the same terms as Perl itself. + +This makes it easy for people to use your module with Perl. Note that +this licensing is neither an endorsement or a requirement, you are of +course free to choose any licensing. + +=item HISTORY + +Programs derived from other sources sometimes have this, or you might keep +a modification log here. If the log gets overly long or detailed, +consider maintaining it in a separate file, though. + +=back + +In addition, some systems use CONFORMING TO to note conformance to relevant +standards and MT-LEVEL to note safeness for use in threaded programs or +signal handlers. These headings are primarily useful when documenting parts +of a C library. Documentation of object-oriented libraries or modules may +use CONSTRUCTORS and METHODS sections for detailed documentation of the +parts of the library and save the DESCRIPTION section for an overview; other +large modules may use FUNCTIONS for similar reasons. Some people use +OVERVIEW to summarize the description if it's quite long. + +Section ordering varies, although NAME should I<always> be the first section +(you'll break some man page systems otherwise), and NAME, SYNOPSIS, +DESCRIPTION, and OPTIONS generally always occur first and in that order if +present. In general, SEE ALSO, AUTHOR, and similar material should be left +for last. Some systems also move WARNINGS and NOTES to last. The order +given above should be reasonable for most purposes. + +Finally, as a general note, try not to use an excessive amount of markup. +As documented here and in L<Pod::Man>, you can safely leave Perl variables, +function names, man page references, and the like unadorned by markup and +the POD translators will figure it out for you. This makes it much easier +to later edit the documentation. Note that many existing translators +(including this one currently) will do the wrong thing with e-mail addresses +or URLs when wrapped in LE<lt>E<gt>, so don't do that. + +For additional information that may be more accurate for your specific +system, see either L<man(5)> or L<man(7)> depending on your system manual +section numbering conventions. + +=head1 SEE ALSO + +L<Pod::Man>, L<Pod::Parser>, L<man(1)>, L<nroff(1)>, L<podchecker(1)>, +L<troff(1)>, L<man(7)> + +The man page documenting the an macro set may be L<man(5)> instead of +L<man(7)> on your system. + +The current version of this script is always available from its web site at +L<http://www.eyrie.org/~eagle/software/podlators/>.

And the answer is: depends on what you +want. All the leading ampersand does is to push the name of the +variable on the stack instead of the value of the variable (w/ all +the COW semantics). So consider this + +void +stomp(string &buf) +{ + buf = "stomped"; +} + +void +L_caller() +{ + string foo = "bar"; + string fooname = "foo"; + + if (what_I_would_expect) { + stomp(&foo); // foo will get "stomped" + } else { + stomp(fooname); // foo will get "stomped" this way too + } +} + +The stomp(fooname) could work but we should disallow it in L 1.0 - we +can allow it in the future. Tim points out that we can throw a syntax +error for L calling L and the type mismatch but not for L calling tcl, +i.e., calling gets, unless we have some sort of extern int gets(FILE fd, +string &buf) that we use to load the function signature table (what is +that called?) + +Tcl calling L + +Suppose we had an L procedure that implemented puts, maybe it's written +in C, but it would be declared like + +void +L_puts(string stuff_to_print[]) +{ + print it +} + +If we are in tcl and we do + + set stuff [list a b c] + +and we want to print it it would look like + + puts $stuff + +but if we're calling L that won't work, it should be an arg miss match because + + L_puts $stuff + +is like calling + + L_puts("a", "b", "c") + +and L_puts wants a single arg. + +We get around this by noting that L implements pass by reference by passing +by name and doing an upvar so the calling syntax is: + + L_puts stuff + +Kind of annoying but that's a ramification of the impedance mismatch between +L and tcl.

L is a new +programming language that shares most of its syntax and semantics with +C, including pointers and a weak static type system.

We spend much more +time reading our source code than writing it. Most of our source base +is written in C, but our GUI is written in Tcl. It would greatly +simplify things for us if everything was in a common language. +However, using Tk from C would be difficult and error-prone. +.pp +For that reason, we've decided to implement a new language that shares +the Tcl runtime. By keeping the language similar to C we can use the +same idioms as we would in C, avoiding confusion. To make access to Tk +and other Tcl libraries seamless, the language runs right in the Tcl +runtime. Its functions are Tcl functions, and its types are Tcl types. +.pp +In keeping with the grand tradition of one letter language names, this +new language is called L. In the next section, we will go into more +detail about some interesting aspects of the language. After that we +discuss its implementation as a front-end for Tcl. Finally we touch +on our plans for the future of L, and tell you where you can get a +copy. +.sh 1 "The L Language" +.lp +Say that we're mostly like C and then go on to describe where we're +different. Explain how L types correspond to Tcl types, and give an +example of the interaction between the two languages. +.\" This is an example reference so that I don't forget how to make one +.[ +kernighan cherry eqn +.] +.sh 1 "The Implementation" +.lp +The first step in processing an L program is to read in the source +code. L source code can be in its own file, or it can be in a mixed +file together with Tcl source code. +.sh 2 "Parsing Mixed Languages" +.lp +The most obvious approach to embedding L code within a Tcl program +would be to pass the L code as an argument to a new Tcl command which +implements L. However, the Tcl syntax rule that "braces nest within a +word" [cite endekalogue/tcl book?] means that we would still be +required to match (or escape) braces within the L code. This would be +an unpleasant wrinkle for the L programmer to deal with. +.pp +In order to free the brace characters from the reign of Tcl, it was +necessary to modify the Tcl parser. We added support for special +comments that start with the word "pragma". The parser consumes the +input from an opening pragma to a closing pragma, and packages it as a +pair of Tcl words -- the name of the command that implements L, +followed by the source code between the pragmas. In this way, the +result of parsing embedded L code is the same as if the L code had +been properly escaped. +.sh 1 "..." +.lp +Mention using Tcl to generate C code, and explain how L pointers work. +Take opportunity to release bile about Tcl being a bizarre backend for +a C compiler. +.sh 1 "Current Status, Availability" +.lp +L is completely finished and golden, and has a magic shield of +2 +anti-bitrot.

H'm. Work that into the talk? +.LP +For years we have used the Tcl/Tk system for our graphical user interfaces. +We periodically consider the alternatives and have consistently found that +short of doing native implementations, the +Tcl/Tk system is still the best choice from a development cost point of +view. +Our estimate is that it would cost roughly six times as much to develop +and maintain native GUIs instead of using a single Tcl source base for all +platforms. +However, the maintenance of our Tcl source base has recently become +problematic because two things happened: +.BU +Our Tcl source base grew past a manageable size (for us). +.BU +Our peer review system could not handle Tcl code. +.LP +We have about 25,000 lines lines of Tcl, implementing about a dozen +graphical interfaces for browsing code, checking in code, viewing changes, +etc.\** +.FS +This number is artificially low because we have been holding off on a number +of GUIs until we had a better answer. Had we not been holding back, 100,000 +lines is more likely where we would be. +.FE +Maintaining and extending the Tcl source base has become unmanageable, and +when the review process was added to the mix, the costs became +too high. +.LP +This has been a problem for us for years and we were forced to come up with +a better answer. +We investigated the alternatives but in the end the Tcl runtime +and the Tk widgets were too compelling. +We solved our problems by marrying a language syntax we felt +was well suited for fast reviewing and understanding with what +we feel is the best GUI toolkit and runtime available today. +.LP +The rest of the paper is divided into sections that discuss the following +topics: +an overview of L, +why the L approach is interesting, +why other runtimes were not chosen, +why not pure Tcl, +why not native GUIs, +L language details such as types, calling/return conventions, +current status, +features we have not yet done but want to do, +licensing and availability, +and a summary. +There is an appendix with some small working program examples. +.NH 1 +L overview +.LP +L is actually a very small addition to the Tcl system. +If we divide the Tcl system into logical parts this becomes obvious: +.TS +expand box; +l l +l c. +Subsection Percentage of Tcl/Tk 8.5 += +Tcl parser/compiler <= 1% +L parser/compiler <= 1% +Tcl runtime 48% +Tk 51% +.TE +.LP +The parser and compiler are quite small when compared to the +code that implements the runtime and the libraries (in both Tcl and L it +is less than 10K lines of code). +Because the parser/compiler is such a small part of the system, it is +reasonable to add an alternative parser/compiler to the +system and let them both run side by side. +That is L in a nutshell. +It is the small amount of effort required to leverage a large amount of +value embodied in the runtime and libraries. +.LP +The L compiler creates an abstract syntax tree from L +source and compiles that to byte codes. +The byte codes generated are standard Tcl byte codes, following Tcl +call/return conventions and using Tcl variables. +Because we are careful not to break any Tcl rules, +L functions may call Tcl procs and vice versa. +This allows L to use the extensive, mature Tcl/Tk runtime +and libraries unmodified. +.NH 1 +Unique design +.LP +As we dive deeper into the L syntax and semantics it would be +easy to be drawn into a discussion of why L is better or why Tcl +is better. +To do so would be to miss an important point. +Regardless of the merits of each language, the value of L +is that it demonstrates a new way to leverage and reuse existing code. +With a relatively small amount of effort, we have leveraged over +1.4 million lines of source making up the Tcl/Tk system plus some +extensions. +.LP +The existence of L opens the door to any number of domain-specific +languages being added to the Tcl runtime system. +.ig +If some group prefers Python syntax we see no reason they could +not take the L scanner and parser, change the syntax to Python, +and add another syntax to Tcl. +A reasonable question is \(lqwhy bother?\(rq because Python has a +runtime. +The answer isn't Python, it is domain specific languages. +Any effort that needs a specific syntax to be interpreted could +take our approach and get the job done for far less effort than +starting from scratch. +.. +.LP +For example, consider the GDB debugger. +GDB lets users type C, C++, etc., at it and run the code. +Doing so means GDB has to provide an interpreter and a runtime. +Rather than building one, GDB could reuse the ideas and code +pioneered by the L effort. +Having a well maintained runtime with the option of creating an +arbitrary syntax to use that runtime is useful for any sort of +debugger or runtime inspector. +L is just one example of a different syntax leveraging the Tcl/Tk system; +we are confident there will be others. +.NH 1 +Alternative runtimes +.LP +Once the idea of adding a different parser/compiler to a scripting +language is understood, the question becomes: why Tcl rather than some +other runtime such as Perl, Python, Ruby, Java, or others? +We looked briefly at that question. +Our need was for a well supported, mature runtime that supported +scripting GUI interfaces and was extensible from C. +.LP +We dismissed Java because the runtime is too large and the GUI toolkits +are weak, both in features and in performance. +The other runtimes addressed the GUI issues mostly by providing Tk +bindings (and in some cases Qt or Gtk bindings). +Any system that is using Tk bindings is already dragging along a Tcl +interpreter to run the Tk code. +It seemed like a waste to have a different interpreter just for the GUIs. +It has also been our experience that the only way to build robust +software systems is to have the minimum number of ``moving parts.'' +Having two interpreters is an unnecessary complication. +.LP +But even if there were a good runtime with a good GUI interface, there was +another requirement we felt was only well addressed by Tcl. +Tcl has been designed from the onset to be an extendable language. +The original vision was that Tcl was glue and all the heavy lifting would +be done by C extensions to the language. +The internal Tcl code is fairly small and quite pleasant to use; adding +extensions is straightforward and natural. +We needed to take advantage of this feature of the Tcl system and other +runtimes made this difficult. +.NH 1 +L vs pure Tcl +.\" Brian went on and on about syntax / lint checker. +.\" Coverity example. +.LP +Many in the Tcl community may question whether there is any value in an +alternate syntax for the Tcl runtime. +After all, Tcl is a powerful, dynamic language and many significant +applications are based on Tcl. +.LP +We agree that Tcl is powerful, but that power comes at a cost. +Tcl's dynamic nature makes it impossible to detect even simple parse +errors, such as typos, without running the program. +.LP +Although there are advantages to the dynamic approach in language +design, there are also drawbacks: +.LI Data structures. +Probably the single largest problem we found with Tcl was the lack of a +C-style struct, i.e., a centralized collection of variables with +annotations indicating why they are there. +These are commonly emulated in Tcl with associative arrays. +That isn't good enough because the ``struct fields'' are +scattered all over the source base rather than being in one place, +laid out with types and comments. +To paraphrase Fred Brooks: +.ft I +\(lqShow me your code and conceal your data structures, and I shall +continue to be mystified. Show me your data structures, and I won't +usually need your code; it'll be obvious.\(rq +.[ +mythical man month +.] +.LI Lint. +It is impossible to write a syntax checker or a lint-like tool for Tcl that +works 100% of the time unless that tool is actually running the program it +is checking. +Even an interpreter-based tool would have the problem that it is not +practical to force the application through all possible code paths. +It is worth noting that this problem is present in all dynamic languages +and object-oriented languages have the same problem; you can't +just look at the code and know what it is doing. +.LI Reviewing. +As mentioned previously, at BitMover we do a lot of peer review as well as +other forms of code reading. +For the same reasons that it is difficult to write a lint-like tool +for Tcl, it is difficult for a human to look at Tcl and understand what +it is doing. +The verbose style of basic operations in Tcl, e.g., +.CS +lset fib $i \\ + [expr \\ + {[lindex $fib [expr {$i-1}]] + + [lindex $fib [expr {$i-2}]]}] +.CE +vs +.CS +fib[i] = fib[i-1] + fib[i-2]; +.CE +tend to obscure what is actually being said in the code. +.LI Optimization. +Optimizing Tcl is more challenging than optimizing a ``weaker'' language +such as L. +Many well understood optimization techniques could be applied to the +compilation of L, resulting in a significant performance increase for +some programs. +As an example, due to the static type system of L, we believe it's +possible to make L immune to ``shimmering.'' +.[ +shimmering +.] +.LP +We tend to view Tcl more like assembly language on steroids. +It is a powerful tool and when that power is needed it is +appreciated. +But most of the time we are doing fairly simplistic programming +deliberately so it is easy to read, and we find that a static language +with a static type system is much easier for us to read and easier +for a compiler to optimize and check. +.NH 1 +L vs native GUIs +.LP +This question gets raised at least once a year here: why not do native +GUIs? +It is certainly possible to do so. +We have done implementations of several of our GUIs in other +toolkits. +The arguments for doing so are compelling: better look and feel, native +behavior, etc. +.LP +The reasons for staying with Tcl/Tk are simple: +.LI Cost. +The cost of creating 2-4 different implementations of each GUI interface is +probably 3 times what it took us to get where we are today. +But the cost does not end there. +The cost extends to testing the GUIs on each platform as well as putting +processes in place to make sure that the GUIs march forward in sync, +i.e., if the Java revtool gets a new feature, that same feature needs to +be added to the Linux, Windows, and Aqua GUIs. +When we add up all the costs, it looks more like 6 times the effort. +.LI Functionality. +Every time we go look at the other toolkits we find that they are not as +powerful as the Tk toolkit. +In particular, the canvas and text widgets are more useful than any others +we have found. +.sp .5 +That said, a large drawback of the Tk approach is the lack of a complete +widget set in the core. +In order to get the functionality needed, a ragtag group of extensions, +with partially overlapping features, need to be combined into a Tcl/Tk +``distribution.'' +We look forward to the day that this issue is resolved. +.NH 1 +L language details +.LP +In this section we cover some of the differences from C, differences +from Tcl, types, call/return conventions, expressions, and control flow. +.NH 2 +Extensions to C +.LI Regex. +L uses Perl's syntax for regular expressions in statements, but it uses +Tcl's regular expression engine. +So you may say: +.CS +if (a =~ /${r}/) {... +.CE +to get the same results as Tcl's +.CS +if {[regexp $r $a]} {... +.CE +.LI Associative arrays. +We call these hashes in L to distinguish them from traditional C-style arrays. +The keys and values are strings. +.LI Arrays grow. +If you assign into an array past the last element the array grows as needed. +Many constructs that would normally use C pointers, such as linked lists +or trees, can be constructed with an array of structures linked via indices +rather than pointers. +.LI defined(). +A built-in that indicates if the variable passed is defined. +The following tests for the existence of the +field in the hash, and the existence of the array element, respectively. +.CS +defined(foo{"bar"}) +defined(stuff[3]) +.CE +.LI Strings. +Strings are first-class objects like any other base type. +One implication of this is that unlike C strings, which are pointers, +if you want to pass a reference to the string you must do so +explicitly. +.NH 2 +Unimplemented C features +.LP +L does not have bit fields, enums, unions, or C-style pointers. +L currently does not have a C-like preprocessor, though one is planned. +.NH 2 +Extensions to Tcl +.LI Type checking. +L has a weak static type system, which makes it possible to do type +checking at compile time. +Note that L's type system is independent of Tcl's runtime type system, +although the two can interoperate. +Variables in L may not change types, unlike Tcl variables, which are +strings except when they're not (as with floats, ints, lists, etc.) +.LI Structs. +C-style structs are part of L. +A Tcl API is provided that supports getting and setting fields as well as +introspection. +.LI References. +Pass by reference in Tcl is possible but awkward. +Attempts have been made to improve it in Tcl +.[ +pass by reference +.] +but they are unsatisfying. +We think our syntax is cleaner and easier to read. +.LI Function prototypes. +Currently these are used to get type checking when calling Tcl built-ins. +For example, we can prototype gets() as +.CS +extern int gets(FILE, string &); +.CE +to always require gets to be called with two arguments. +We could also prototype gets() as +.CS +extern string gets(FILE); +.CE +to make it return a string. +If prototypes are missing, L treats undefined functions as external Tcl +functions that return poly and take a variable number of arguments of +type poly. +.br +.ne 20 +.NH 2 +Types +.NH 3 +Simple types +.LI int. +Integer types in L are like C integers: they are sized to the +machine's word size (at least 32 bits and possibly 64). +Integers in L are initialized to 0, even for local variables. +.CS +int a = 5; +int b; // defaults to 0 +.CE +.LP +Any constant that looks like an int is typed as an int. +.LI float. +Floating-point numbers in L are at least double-precision IEEE 754. +Floats are initialized to 0.0, even for local variables. +.LP +Any constant that looks like a float is typed as a float. +Note that this means that assigning an integer to a float is only +legal because of automatic type conversion. +.CS +float f = 1; // converts to 1.0 +float g; // defaults to 0.0 +float pi = 3.14159265; +.CE +.LI string. +The string type is the same as a Tcl string but different from a C string. +Strings are not null-terminated as they are in C, nor are they arrays +of bytes. +L strings are Tcl strings, which are UTF-8 encoded and have a known +length. +L strings are initialized to the empty string. +.LP +To iterate over each character in a string, use the defined() operator: +.CS +int i; +string s = "a string"; +.sp .5 +for (i = 0; defined(s[i]); i++) { + printf("s[%d]=%s\\n", i, s[i]); +} +.CE +Note that there is no separate character type in L. +When indexing into a string, each character is merely a string of length 1. +This also means that there is no need to use special single-quoted +syntax for character literals: +.CS +str[i] = "c"; +.CE +L provides a special escape sequence, ${, which allows embedding code in +strings. +All the text from ${ to the matching } is collected and evaluated. +Its value is then substituted into the string: +.CS +int i = 41; +.sp .5 +printf("41 + 1 is ${i + 1}\\n"); +.CE +prints: +.CS +41 + 1 is 42 +.CE +.NH 3 +Tclish types +.LI poly. +This is a generic type that is like a Tcl variable on which no type checking +is done. +Normal variables cause compile-time errors if they attempt to +change types; a poly variable suppresses the static type checking so +that a variable can switch from one type to another, e.g. float to +array or to int, etc. +The following is legal code: +.CS +poly unchecked; +string s; +.sp .5 +unchecked = 1; +unchecked = "Hey there"; +unchecked = 3.14; +// cast is required +s = (string)unchecked; +.CE +.LI var. +This is a compromise variable type. +It is type-checked but the type is not +set until the first assignment. +The type is determined from the assignment and may not change. +The following throws an error: +.CS +var late_binding; +.sp .5 +late_binding = 1; +late_binding = "Hey there"; +.CE +As we noted above, constant types are intuited. +This might cause problems with @var@ variables. +For example, this throws an error: +.CS +var f = 1; // f is now an int +.sp .5 +f = "pi"; // int/string error +.CE +but this works fine: +.CS +var f = 1.0; +.sp .5 +f += 3.14; +.CE +.NH 3 +Magic +.LI :constant. +Many Tcl/Tk interfaces take key/value pairs that look like +.CS +text .t -bg white -fg black +.CE +which in L might look like +.CS +text(".t", + "-bg", "white", "-fg", "black"); +.CE +We wanted a way to make the @-whatever@ stand out from the values being passed +as an argument to @-whatever@. +We decide to do that like this: +.CS +text(".t", + :bg, "white", :fg, "black"); +.CE +When the parser sees an identifier in a function call that has a leading +colon, L treats it as if it were a quoted string with the colon replaced +by a dash. +.NH 3 +Compound types +.LI array. +Arrays are like C arrays in syntax but are implemented as Tcl lists under +the covers. +Array elements are homogeneous; all elements must share the same type. +Array assignments in declarations are supported for globals and locals: +.CS +string foo[] = { "Hi", "there" }; +int bar[] = { 1, 2, 3, 4 }; +int i; +int total = 0; +.sp .5 +for (i = 0; defined(bar[i]); i++) { + total += bar[i]; +} +.CE +Arrays are dynamically grown and cannot be sparse. +.CS +int a[2]; +.sp .5 +a[0] = 10; +a[100] = 20; // allowed +.CE +After the previous code has been executed, @a@ has 101 elements. +@a[1]@ to @a[99]@ have the value 0, which is the default initial +value for integers. +.LP +The defined operator is an easy way to check if an index is outside +the array bounds: +.CS +// prints 'no' +if (defined(a[101])) { + printf("yes\\n"); +} else { + printf("no\\n"); +} +.CE +.LI hash. +Hashes are associative arrays, indexed by strings and returning string +values. +They are implemented by Tcl dictionaries under the covers. +Hash assignments in declarations are supported for globals and locals +and follow the Perl syntax: +.CS +hash h = { "key" => "val", + "key2" => "val2" }; +.sp .5 +h{"foo"} = "bar"; +if (defined(h{"blech"})) { + printf("blech is not a key!\\n"); +} +.CE +.LP +The defined operator can also be used to check if a key is present in a +hash: +.CS +// prints no +if (defined(foo{"k"})) { + printf("yes\\n"); +} else { + printf("no\\n"); +} +.CE +.br +.ne 10 +.LP +It is possible to iterate over each value in a hash using a foreach +loop: +.CS +foreach (h as k => v) { + printf("%s => %s\\n", k, v); +} +.CE +.LI struct. +Structs are collections of typed variables, as in C. +Declarations are the same as C declarations. +Struct assignments in declarations are supported for globals and locals: +.CS +typedef struct { + int a; + float b; + string c; +} eg; +.sp .5 +eg s = { 1, 3.14, "hi there" }; +.CE +.LP +Structures are implemented as Tcl lists just like L arrays. +The names are translated into integer indices by the L compiler. +Since it is just a Tcl list, an L structure can be passed to any Tcl proc +that expects a list. +.LP +It is likely that we will extend the struct construct to have initializers, +e.g., +.CS +typedef struct { + int a = 1; + float b = 3.14; + string c = "hi there"; +} eg; +.sp .5 +eg foo; +puts(foo.a); // prints 1 +.CE +.NH 2 +Passing semantics +.LP +A C programmer, looking at Tcl, would think that the Tcl model is pass by +value. +While Tcl has no way to pass a C-style pointer to an object, it does have +a way to fake it with something called @upvar@. +L wants pass by value but it also wants to provide pass by reference. +This section describes how we used the Tcl system to provide the L passing +semantics. +It amounts to a little syntactic sugar on top of @upvar@. +.NH 3 +By value +.LP +L obeys Tcl's semantics for pass by value. +Parameter passing looks like it does in C: +.CS +int i = 1234; +.sp .5 +foo(i, 0xdeadbeef, "string"); +.CE +L programs typically do not pass compound types by value to other +L functions (but see the @(tcl)@ cast below for how to pass them to +Tcl procs). +.br +.ne 8 +.NH 3 +By reference +.LP +The Tcl system has a way of passing by reference that might appear strange +to C programmers. +.CS +proc foo {ref} { + upvar $ref pointer + + set pointer 1 +} +.CE +The @upvar@ command creates a reference to the variable in the caller's +context and places it in @pointer@. +Assignments to @pointer@ are the same as if the assignment were done in +the caller's context (after evaluating the right-hand side). +.LP +We used this mechanism to emulate pass by reference in L. +We call it ``pass by name'' because the caller is putting the name +of the variable on the stack and the callee is doing an automatic +@upvar@ to create the reference. +The syntax looks like: +.CS +void foo(int &ref) +{ + ref = 1234; +} + +int a = 19; +.sp .5 +foo(&a); +puts(a); +.CE +and that prints +.CS +1234 +.CE +Arrays and hashes do not take the ampersand because they are trying to +behave like C arrays, i.e., they are already references. +.CS +void clear(int v[]) +{ + int i; +.sp .5 + for (i = 0; defined(v[i]); i++) { + v[i] = 0; + } +} +.sp .5 +int junk[] = { 1, 2, 3 }; +.sp .5 +clear(junk); // junk = { 0, 0, 0 } +.CE +Note that strings, unlike in C, are first-class objects and are +.B not +references. +If you want to modify a string, you must pass it by reference. +For example, to use the Tcl built-in for reading a line of input +you have to do this: +.CS +string buf; +.sp .5 +// buf is an out parameter +gets(stdin, &buf); +.CE +.NH 3 +L pointers +.LP +While the @upvar@ trick works nicely for many cases, there is still a need +for real pointers. +When creating a widget, such as an entry box, it would be natural to +have a struct that contained all the things related to that widget +such as its path, the variable that the entry box sets, etc., like so: +.CS +widgets(entry &e) +{ + e.frame = frame(".f"); + e.entry = entry("${top}.entry"); + e.entry("configure", + :textvariable, &e.textvar); +} +.CE +Our trick of making an ampersand mean ``push the variable name on the +stack'' does not work here for multiple reasons. +First, the variable in this case is a structure field, which is an element +of a Tcl list. +There is currently no way to pass a list element as a @-variable@ argument; +Tcl does not support that. +Second, @-variable@ arguments must be accessible at the global scope. +There is no guarantee that the name passed in makes sense at the global scope. +.LP +What is needed is a way to take an L variable and turn it into something +that Tcl can find out of the event loop. +The natural answer is some kind of pointer. +.LP +We created a new Tcl object type to hold all the information related to a +pointer. +The information looks like: +.CS +struct pointer { + int depth; // upvar #depth + string name; // var pointed to + string index; // optional index +}; +.CE +The depth field is used to get to the call frame where the variable being +pointed at was declared. +For GUI code like the example above, the depth is almost always 0, +indicating a global. +The string is the name of the variable to which the pointer refers. +If the underlying type of the variable is a list (remember that structs +are implemented as lists) then the index is the index into that list. +The index is a string because in the future we intend to make pointers +into hashes work. +.br +.ne 20 +.LP +There is a new Tcl command, @pointer@, which may be used to manipulate +pointers from Tcl directly. +The following code creates a pointer, +points it at the last element of the list @l@, +uses the pointer to get the value of the variable pointed at, +and uses the pointer to set the value of the variable pointed at to @foo@. +When we are done, @$l@ contains \fIa\ b\ foo\fP. +.CS +set l [list a b c] +set p [pointer create l] +pointer index $p 2 +pointer get $p # prints c +pointer set $p foo +.CE +Let's now consider the widget example above, remembering that it had a +variable reference @&e.textvar@. +The compiler provides some magic to treat that construct as +an L pointer. +When the compiler sees a string constant of the form @-.*variable@\** and +the next token is an L variable with a leading ampersand, +the compiler automatically wraps the variable in an L pointer. +.FS +Remember that @:foo@ token is just syntactic sugar for ``@-foo@.'' +.FE +.NH 3 +Return values +.LP +Because returns are by value in L, and Tcl also returns by value, +no changes were required to make returns work in L. +.LP +It is worth noting, especially for C programmers, that there is a sneaky +way to do an allocation. +When a local variable is returned, the return bumps the reference count. +Without that bump, the local variable in question would have been freed +along with any other locals that were on the callee's stack. +Tcl objects are reference counted so the variable will get freed when +the caller is finished with it. +.CS +string[] +vector(int n) +{ + string v[]; +.sp .5 + // Allocate 0..n-1 + v[n - 1] = ""; + return (v); +} + +string foo[] = v(100); +.CE +.NH 2 +Casts +.LI (tcl). +There are times when we need to pass a compound object (array, +hash) as a string. +Any Tcl proc that expects to see a string on the stack will want this. +The @(tcl)@ cast is used to do this. +.CS +string v[] = { "hi", "good day" }; +.sp .5 +puts((tcl)v); +.CE +prints +.CS +hi {good day} +.CE +.LI (L). +There may be times when a Tcl proc is returning a complex structure to us +and we want to cast it from the Tcl list to our structure: +.CS +#lang(tcl) +proc demo {} { + return [list {good day} sir] +} +.sp .5 +#lang(L) +v = (L)demo(); +printf("%s %s\\n", v[0], v[1]); +.CE +prints +.CS +good day sir +.CE +Note: doing this sort of thing puts you at the mercy of the Tcl code +which knows nothing about the L type system. +.NH 2 +Operators +.LP +L supports most of the operators in the C programming language, as well +as several of the most useful operators from Perl. +In this section we do a quick run through all of the operators in L +and discuss some of their more subtle aspects in depth. +.LP +Much of this section is cribbed from the C reference manual. +.[ +C +.] +.NH 3 +Arithmetic operators +.LP +The binary arithmetic operators in L are +, -, *, /, and % (modulus). +They work as in C with the C precedence rules. +.NH 3 +True vs. false +.LP +All of the relational and logical operators are part of an expression and +that expression evaluates to either true or false. +.LP +In L, there is only one false value. +This is different from Tcl, which allows many false values, such as the +strings ``false'' and ``off.'' +The false value in L is 0, or, equivalently, ``0''. +Any value other than 0 is considered true. +.CS +if (0) { + printf("consequent\\n");

Whenever the parser sees @#lang(L)@ it +stops normal parsing and inserts two tokens into the token stream. The +first token is a call to the @LCompileCommand@ function and the second +is the text after the @#lang(L)@ comment up to the next @#lang(tcl)@ +comment or end-of-file. +.EQ +delim || +.EN +.NH 1 +Status +.LP +The L language is under active development and the speed of development +is increasing. +Our expectation is that we will have a usable system in 1-2 months. +Our goal is to be rewriting our GUI tools in L early in 2007. +There is a mailing list, \f(CWl@bitmover.com\fP, and an IRC channel, +\f(CW##l\fP on \f(CWFreenode\fP. +People are welcome to join either. +.NH 1 +Future work +.NH 2 +Scoping +.LP +Like a C source file, a scope provides a container for private and/or +public variables and/or functions. +This could be used to provide a self-contained ``class.'' +.NH 2 +Pre-compiled modules +.LP +Imagine that each scope is a module and each module can be pre-compiled. +The on-disk format is in sections: there is a byte-code section and a +sort of table of contents which can be thought of as a header file containing +function prototypes. +.NH 2 +Optimizations +.LP +The dynamic nature of Tcl means that many traditional compiler optimization +techniques cannot be used. +L compiles the source to an abstract syntax tree and could take advantage +of a number of well known optimizations. +These include: constant subexpression elimination, +dead code removal, strength reduction, loop invariant code +motion, tail-call optimization, code hoisting, and others. +.[ +optimization +.] +.LP +The lack of general C-like pointers in L greatly simplifies alias analysis +and makes it possible to be more aggressive when applying optimizations. +.[ +aliasing1 +.] +.[ +aliasing2 +.] +.NH 2 +Debugging +.LP +The static nature of L code would make it possible to create a +mapping between L source code and Tcl byte codes such that traditional +debugging techniques could be used.
