-[description]
-[para]
-TkCon is a replacement for the standard console that comes with Tk
-(on Windows/Mac, but also works on Unix).
-The console itself provides many more features than the standard
-console.
-TkCon works on all platforms where Tcl/Tk is available.
-It is meant primarily to aid one when working with the little
-details inside Tcl and Tk, giving Unix users the GUI console
-provided by default in the Mac and Windows Tk.
-
-[list_begin definitions]
-[call [cmd tkcon] [lb]\{[arg option] [arg value] | [arg tcl_script]\} ...[rb]]
-[list_end]
-
-[section OPTIONS]
-[para]
-Except for [cmd -rcfile], command line arguments are handled after
-the TkCon resource file is sourced, but before the slave
-interpreter or the TkCon user interface is initialized.
-
-[para]
-[cmd -rcfile] is handled right before it would be sourced,
-allowing you to specify any alternate file.
-Command line arguments are passed to each new console and
-will be evaluated by each.
-To prevent this from happening, you have to say
-
-[example_begin]
-tkcon main set argv {}; tkcon main set argc 0
-[example_end]
-
-[para]
-For these options, any unique substring is allowed.
-
-[list_begin definitions]
-[def "[cmd -argv] (also [cmd --])"]
-Causes TkCon to stop evaluating arguments and set the remaining
-args to be argv/argc (with [cmd --] prepended).
-This carries over for any further consoles.
-This is meant only for wrapping TkCon
-around programs that require their own arguments.
-
-[def "[cmd -color-<color>] [arg color]"]
-Sets the requested color type to the specified color for tkcon.
-See [cmd tkconrc](5) for the recognized [cmd <color>] names.
-
-[def "[cmd -eval] [arg tcl_script] (also [cmd -main] or [cmd -e])"]
-A Tcl script to eval in each main interpreter.
-This is evaluated after the resource file is loaded and the
-slave interpreter is created.
-Multiple [cmd -eval] switches will be recognized (in order).
-
-[def "[cmd -exec] [arg slavename]"]
-Sets the named slave that tkcon operates in.
-In general, this is only useful to set to [arg {""}] (empty),
-indicating to tkcon to avoid the multi-interpreter model and
-operate in the main environment.
-When this is empty, any further arguments will be only used
-in the first tkcon console and not passed onto further new consoles.
-This is useful when using tkcon as a console for extended wish
-executables that don't load there commands into slave interpreters.
-
-[def "[cmd -font] [arg font]"]
-Sets the font that tkcon uses for its text windows.
-If this isn't a fixed width font, tkcon will override it.
-
-[def "[cmd -nontcl] [arg TCL_BOOLEAN]"]
-Sets [cmd ::tkcon::OPT(nontcl)] to [arg TCL_BOOLEAN] (see
-[cmd tkconrc](5)).
-Needed when attaching to non-Tcl interpreters.
-
-[def "[cmd -package] [arg package_name] (also [cmd -load])"]
-Packages to automatically load into the slave interpreters (i.e. "Tk").
-
-[def "[cmd -rcfile] [arg filename]"]
-Specify an alternate tkcon resource file name.
-
-[def "[cmd -root] [arg widgetname]"]
-Makes the named widget the root name of all consoles (i.e. .tkcon).
-
-[def "[cmd -slave] [arg tcl_script]"]
-A Tcl script to eval in each slave interpreter.
-This will append the one specified in the tkcon resource file, if any.
-
-[list_end]
-
-[section {KEY BINDINGS}]
-[para]
-Most of the bindings are the same as for the [cmd text] widget.
-Some have been modified to make sure that the integrity of the
-console is maintained.
-Others have been added to enhance the usefulness of the console.
-Only the modified or new bindings are listed here.
-
-[list_begin definitions]
-
-[def "[cmd Control-x] or [cmd Cut] (on Sparc5 keyboards)"]
-Cut.
-
-[def "[cmd Control-c] or [cmd Copy] (on Sparc5 keyboards)"]
-Copy.
-
-[def "[cmd Control-v] or [cmd Paste] (on Sparc5 keyboards)"]
-Paste.
-
-[def [cmd Insert]]
-Insert (duh).
-
-[def [cmd Up]]
-Goes up one level in the commands line history when cursor is on
-the prompt line, otherwise it moves through the buffer.
-
-[def [cmd Down]]
-Goes down one level in the commands line history when cursor
-is on the last line of the buffer, otherwise it moves through the buffer.
-
-[def [cmd Control-p]]
-Goes up one level in the commands line history.
-
-[def [cmd Control-n]]
-Goes down one level in the commands line history.
-
-[def [cmd Tab]]
-Tries to expand file path names, then variable names, then proc names.
-
-[def [cmd Escape]]
-Tries to expand file path names.
-
-[def [cmd Control-P]]
-Tries to expand procedure names.
-The procedure names will be those that are actually in the attached
-interpreter (unless nontcl is specified, in which case it always
-does the lookup in the default slave interpreter).
-
-[def [cmd Control-V]]
-Tries to expand variable names (those returned by [lb]info vars[rb]).
-It's search behavior is like that for procedure names.
-
-[def "[cmd Return] or [cmd Enter]"]
-Evaluates the current command line if it is a complete command,
-otherwise it just goes to a new line.
-
-[def [cmd Control-a]]
-Go to the beginning of the current command line.
-
-[def [cmd Control-l]]
-Clear the entire console buffer.
-
-[def [cmd Control-r]]
-Searches backwards in the history for any command that contains
-the string in the current command line.
-Repeatable to search farther back.
-The matching substring off the found command will blink.
-
-[def [cmd Control-s]]
-As above, but searches forward (only useful if you searched too far back).
-
-[def [cmd Control-t]]
-Transposes characters.
-
-[def [cmd Control-u]]
-Clears the current command line.
-
-[def [cmd Control-z]]
-Saves current command line in a buffer that can be retrieved
-with another [cmd Control-z].
-If the current command line is empty, then any saved command
-is retrieved without being overwritten, otherwise the current
-contents get swapped with what's in the saved command buffer.
-
-[def [cmd Control-Key-1]]
-Attaches console to the console's slave interpreter.
-
-[def [cmd Control-Key-2]]
-Attaches console to the console's master interpreter.
-
-[def [cmd Control-Key-3]]
-Attaches console to main TkCon interpreter.
-
-[def [cmd Control-A]]
-Pops up the "About" dialog.
-
-[def [cmd Control-N]]
-Creates a new console. Each console has separate state, including
-it's own widget hierarchy (it's a slave interpreter).
-
-[def [cmd Control-q]]
-Close the current console OR Quit the program (depends on the
-value of [cmd ::tkcon::TKCON(slaveexit)]).
-
-[def [cmd Control-w]]
-Closes the current console.
-Closing the main console will exit the program (something has
-to control all the slaves...).
-
-[list_end]
-
-[para]
-TkCon also has electric bracing (similar to that in emacs).
-It will highlight matching pairs of {}'s, [lb][rb]'s, ()'s and ""'s.
-For the first three, if there is no matching left element for the right,
-then it blinks the entire current command line.
-For the double quote, if there is no proper match then it just blinks
-the current double quote character.
-It does properly recognize most escaping (except escaped escapes),
-but does not look for commenting (why would you interactively
-put comments in?).
-
-[section COMMANDS]
-[para]
-There are several new procedures introduced in TkCon to improve
-productivity and/or account for lost functionality in the Tcl
-environment that users are used to in native environments.
-There are also some redefined procedures.
-Here is a non-comprehensive list:
-
-[list_begin definitions]
-
-[def "[cmd alias] ?[arg sourceCmd] [arg targetCmd] ?[arg arg] [arg arg] ...??"]
-Simple alias mechanism.
-It will overwrite existing commands.
-When called without args, it returns current aliases.
-Note that TkCon makes some aliases for you (in slaves).
-Don't delete those.
-
-[def "[cmd clear] ?[arg percentage]?"]
-Clears the text widget.
-Same as the <[cmd Control-l]> binding, except this will accept a
-percentage of the buffer to clear (1-100, 100 default).
-
-[def "[cmd dir] ?[arg -all]? ?[arg -full]? ?[arg -long]?\
- ?[arg pattern] [arg pattern] ...?"]
-Cheap way to get directory listings.
-Uses glob style pattern matching.
-
-[def "[cmd dump] [arg type] ?[arg -nocomplain]? ?[arg {-filter pattern}]?\
- ?[cmd --]? [arg pattern] ?[arg pattern] ...?"]
-The dump command provides a way for the user to spit out state
-information about the interpreter in a Tcl readable (and
-human readable) form.
-See [cmd dump](n) for details.
-
-[def "[cmd echo] ?[arg arg] [arg arg] ...?"]
-Concatenates the args and spits the result to the console (stdout).
-
-[def "[cmd edit] ?[arg {-type type}]? ?[arg {-find str}]?\
- ?[arg {-attach interp}]? [arg arg]"]
-Opens an editor with the data from arg.
-The optional type argument can be one of: [arg proc], [arg var] or [arg file].
-For proc or var, the arg may be a pattern.
-
-[def "[cmd idebug] [arg command] ?[arg args]?"]
-Interactive debugging command.
-See [cmd idebug](n) for details.
-
-[def "[cmd lremove] ?[arg -all]? ?[arg -regexp] [arg -glob]?\
- [arg list] [arg items]"]
-Removes one or more items from a list and returns the new list.
-If [arg -all] is specified, it removes all instances of each item
-in the list.
-If [arg -regexp] or [arg -glob] is specified, it interprets each item in
-the items list as a regexp or glob pattern to match against.
-
-[def [cmd less]]
-Aliased to [cmd edit].
-
-[def [cmd ls]]
-Aliased to [cmd dir] [arg -full].
-
-[def [cmd more]]
-Aliased to [cmd edit].
-
-[def "[cmd observe] [arg type] ?[arg args]?"]
-This command provides passive runtime debugging output for
-variables and commands.
-See [cmd observe](n) for details.
-
-[def "[cmd puts] (same options as always)"]
-Redefined to put the output into TkCon.
-
-[def "[cmd tkcon] [arg method] ?[arg args]?"]
-Multi-purpose command.
-See [cmd tkcon](n) for details.
-
-[def "[cmd tclindex] [arg {?-extensions patternlist? ?-index TCL_BOOLEAN?\
- ?-package TCL_BOOLEAN? ?dir1 dir2 ...?}]"]
-Convenience proc to update the [file tclIndex] (controlled by [arg -index] switch)
-and/or [file pkgIndex.tcl] (controlled by [arg -package] switch) file in the named
-directories based on the given pattern for files.
-It defaults to creating the [file tclIndex] but not the [file pkgIndex.tcl] file,
-with the directory defaulting to [lb]pwd[rb].
-The extension defaults to *.tcl, with *.[lb]info sharelibextension[rb]
-added when [arg -package] is true.
-
-[def "[cmd unalias] [arg cmd]"]
-unaliases command.
-
-[def "[cmd what] [arg string]"]
-The what command will identify the word given in string in
-the Tcl environment and return a list of types that it was recognized as.
-Possible types are: alias, procedure, command, array variable,
-scalar variable, directory, file, widget, and executable.
-Used by procedures dump and which.
-
-[def "[cmd which] [arg command]"]
-Like the [syscmd which] command of Unix shells, this will tell you if a
-particular command is known, and if so, whether it is internal or
-external to the interpreter.
-If it is an internal command and there is a slot in [cmd auto_index] for it,
-it tells you the file that [cmd auto_index] would load.
-This does not necessarily mean that that is where the file came from,
-but if it were not in the interpreter previously, then that
-is where the command was found.
-
-[list_end]
-
-[para]
-There are several procedures that I use as helpers that some may find
-helpful in there coding (i.e. expanding pathnames). Feel free to lift
-them from the code (but do assign proper attribution).
-
-[section EXAMLPES]
-[para]
-Some examples of tkcon command line startup situations:
-
-[example_begin]
-[cmd megawish] /usr/bin/tkcon [cmd -exec] "" [cmd -root] .tkcon [arg mainfile.tcl]
-[example_end]
-
-Use tkcon as a console for your [cmd megawish] application.
-You can avoid starting the line with megawish if that is the
-default [cmd wish] that TkCon would use.
-The [cmd -root] ensures that tkcon will not conflict with the
-application root window.
-
-[example_begin]
-[cmd tkcon] [cmd -font] "Courier 12" [cmd -load] Tk
-[example_end]
-
-Use the courier font for TkCon and always load Tk in slave
-interpreters at startup.
-
-[example_begin]
-[cmd tkcon] [cmd -rcfile] ~/.wishrc [cmd -color-bg] white
-[example_end]
-
-Use the ~/.wishrc file as the resource file, and a white
-background for TkCon's text widgets.
-
-[section FILES]
-TkCon will search for a resource file in [file ~/.tkconrc].
-TkCon never sources the [file ~/.wishrc] file.
-The resource file is sourced by each new instance of the console.
-An example resource file is provided in [cmd tkconrc](5).
