In the past it has also been compiled -with earlier versions of Think, but no guarantees are made that the -source is still compatible with those versions. (Think C 5.0 appears -to be OK.) Likewise, new compiler versions may effectively change the -language accepted (or the library provided!) and thus cause problems. - -MPW is a special case -- it used to be possible to build Python as -an MPW tool using MPW 3.2, and this may still work, but I haven't -tried this lately. What I have tried, however, is building Python -as a shared library for CFM-68K, using the Symantec C compiler for MPW. -See subdirectory MPW and the README file there for more info. - - -1. Using Think C 6.0 (or 7.0) -============================= - -1.1 The directory structure ---------------------------- - -I duplicate the UNIX directory structure from the distribution. The -subdirectories needed to compile are: Mac, Include, Parser, Python, -Objects, Modules. (Don't bother with Grammar and the parser -generator, nor with the Doc subdirectory.) - -For running and testing, you also need Lib and its subdirectories test -and stdwin. You could also copy some things from the Demo/stdwin -directory (unfortunately most other demos are UNIX specific and even -many stdwin demos are). - -Make sure there is no config.c file in the Modules subdirectory (if -you copy from a directory where you have done a UNIX build this might -occur). Also don't use the config.h generated on UNIX. - -1.2 The project file --------------------- - -I put all source files in one project, which I place in the parent -directory of the source directories. - -1.2.1 Project type - -(This is the Set Project Type... dialog in the Project menu.) - -Set the creator to PYTH; turn on "far data"; leave "far code" and -"separate strs" unchecked (they just serve to bloat the application). -A partition size of 1000K should be enough to run the standard test -suite (which requires a lot of memory because it stress tests the -parser quite a bit) and most demos or medium-size applications. The -interpreter will do basic things in as little at 500K but this may -prevent parsing larger modules. - -1.2.2 Compiler options - -(This is the Options -> THINK C ... dialog in the Edit menu.) - - - Start with Factory Settings. - - - In the Prefix, remove #include <MacHeaders> and add - #define HAVE_CONFIG_H - - - Choose any optimizer and debugger settings you like. - You - can choose 4-byte ints if you want. This requires that you - rebuild the ANSI and unix libraries with 4-bytes ints as well - (better make copies with names like ANSI 32 bit). With 4-byte - ints the interpreter is marginally bigger and somewhat (~10%) - slower, but Python programs can use strings and lists with - more than 32000 items (with 2-byte ints these can cause - crashes). The range of Python integers is not affected (these - are always represented as longs). In fact, nowadays I always - use 4-byte integers, since it is actually rather annoying that - strings >= 64K cause crashes. - -1.2.3 Files to add - -(This is the Add Files... dialog in the Source menu.) - -The following source files must be added to the project. I use a -separate segment for each begin letter -- this avoids segment -overflow, except for 'c', where you have to put either ceval.c or -compile.c in a separate segment. You could also group them by -subdirectory or function, but you may still have to split segments -arbitrarily because of the 32000 bytes restriction. - - - From Mac: all .c files. - - - From Parser: acceler.c, grammar1.c, - myreadline.c, node.c, parser.c, parsetok.c, tokenizer.c. - - - From Python: bltinmodule.c, ceval.c, cgensupport.c, - compile.c, errors.c, getargs.c getopt.c, graminit.c, import.c, - importdl.c, marshal.c, modsupport.c, mystrtoul.c, - pythonmain.c, pythonrun.c, sigcheck.c, structmember.c, - sysmodule.c, traceback.c (i.e. all .c files except dup2.c, - fmod.c, frozenmain.c, getcwd.c, getmtime.c, memmove.c, - sigcheck.c, strerror.c, strtod.c, thread.c) - - - From Objects: all .c files except xxobject.c. - - - From Modules: all the modules listed in config.c (in the Mac - subdirectory) in the initializer for inittab[], before - "ADDMODULE MARKER 2". Also add md5c.c if you add md5module.c, - and regexpr.c if you add regexmodule.c. (You'll find - macmodule.c in the Mac subdirectory, so it should already have - been added in a previous step.) Note that for most modules, - the source file is called <name>module.c, but for a few long - module names it is just <module>.c. Don't add stdwinmodule.c - yet, - -The following THINK C libraries must be added: from Standard -Libraries, ANSI and unix; from Mac Libraries, MacTraps. I put each -library in a separate segment. Also see my earlier remark on 4-byte -ints. - -1.4 Adding STDWIN ------------------ - -STDWIN is built in two separate projects: stdwin.pi contains the core -STDWIN implementation from Ports/mac, textedit.pi contains the files -from Packs/textedit. Use the same compiler options as for Python and -the same general source setup (in a sister directory of the toplevel -Python directory). Put all sources in the same segment. To -stdwin.pi, also add Tools/strdup.c and Gen/wtextbreak.c. - -The two projects can now be added as libraries to the Python project. -You must also add stdwinmodule.c and add "#define USE_STDWIN" to the -Prefix in the compiler options dialog (this only affects macmain.c and -config.c). - -Note that stdwinmodule.c contains an #include statement that -references "stdwin.h" by relative path name -- if the stdwin toplevel -directory is not a sibling of the python toplevel directory, you may -have to adjust the number of colons in the pathname. - -1.5 Resources -------------- - -Since I created them with ResEdit I have no text source of the -resources needed to give the application an icon etc... You can copy -the size, bundle, file reference and icon resources from the -distributed Python application with ResEdit. THINK C automatically -copies resources into the application file from a file -<projectname>.rsrc. - -1.6 Think C 5.0 ---------------- - -Tim Gilbert adds one note that will be helpful to future Think C 5.0 -users: When you have a really big project like python, and you want to -compile and run it, if you just hit Command-R, often Think C will -compile the remaining files, think for a moment, and then give you a -warning "internal error(ZREF)--please remove objects." Don't listen -to it. It is lying. What you should do instead is "Check Link..." -and _then_ hit Run. Why? Ask Symantec. - - -2. Using MicroWerks CodeWarrior 5.0 -=================================== - -Essentially, follow the instructions for Think C. - -XXX Should at least list the project options. - - ---Guido van Rossum, CWI, Amsterdam <Guido.van.Rossum@cwi.nl> -<URL:http://www.cwi.nl/cwi/people/Guido.van.Rossum.html> diff --git a/Mac/USING b/Mac/USING deleted file mode 100644 index 364c3ec..0000000 --- a/Mac/USING +++ /dev/null @@ -1,131 +0,0 @@ -PYTHON RELEASE NOTES FOR THE MACINTOSH - -VERSION 1.1 - -For the most part, Python on the Mac works just like Python under UNIX. -The most important differences are: - -- Since there is no shell environment on the Mac, the start-up file - has a fixed name: PythonStartup. If a file by this name exists - (either in the current folder or in the system folder) it is executed - when an interactive interpreter is started. - -- The default search path for modules is different: first the current - directory is searched, then the subdirectories 'lib', 'lib:stdwin' and - 'demo'. As always, you can change this (e.g. in your PythonStartup - file) by assigning or appending to sys.path -- use Macintosh pathnames! - (The default contains no absolute paths because these are unlikely - to make sense on other people's hard disks.) - -- The user interface for typing interactive commands is different. - This is actually the THINK C console I/O module, which is based on - the Mac toolbox TextEdit. A standard Edit menu provides Cut, Copy, - Paste and Clear (Undo is only there for Desk Accessories). A minimal - File menu provides Quit, which immediately exits the application, - without the usual cleanup. You can Copy from previous output, - but you can't scroll back beyond the 24x80 screen. The TAB key - always brings you to the end of the current input line; indentation - must be entered with spaces (a single space is enough). - End-of-file is generated by Command-D; Command-Period interrupts. - There is an annoying limit in the length of an input line to a single - screen line (less the prompt). Use \ to input long statements. - Change your program if it requires long lines typed on input. - Even though there is no resize box, the window can be resized by - dragging its bottom right corner, but the maximum size is 24x80. - -- Tabs in module files are interpreted as 4 (four!) spaces. This is - consistent with most Mac editors that I know. For individual files - you can change the tab size with a comment like - - # vi:set tabsize=8: - - (exactly as shown here, including the colons!). If you are consistent - in always using tabs for indentation on UNIX, your files will be - parsed correctly on the Mac, although they may look funny if you - have nicely lined-up comments or tables using tabs. Never using tabs - also works. Mixing tabs and spaces to simulate 4-character indentation - levels is likely to fail. - -- You can start a script from the Finder by selecting the script and - the Python interpreter together and then double clicking. If you - make the owner of the script PYTH (the type should always be TEXT) - Python will be launched if you double click it! - There is no way to pass command line arguments to Python scripts. - -- The set of built-in modules is different: - - = Operating system functions for the 'os' module is provided by the - built-in module 'mac', not 'posix'. This doesn't have all the - functions from posix, for obvious reasons (if you know the Mac - O/S a little bit). The functions in os.path are provided by - macpath, they know about Mac pathnames etc. - - = None of the UNIX specific modules ('socket', 'pwd', 'grp' etc.) - exists. - - = Module 'stdwin' is always available. It uses the Mac version of - STDWIN, which interfaces directly with the Mac toolbox. The most - important difference is in the font names; setfont() has a second - argument specifying the point size and an optional third one - specifying the variation: a single letter character string, - 'i' for italics, 'b' for bold. Note that when STDWIN is waiting - for events, the standard File and Edit menus are inactive but - still visible, and (most annoyingly) the Apple menu is also inactive; - conversely, menus put up by STDWIN are not active when the Python is - reading from the keyboard. If you open Python together with a text - file containing a Python script, the script will be executed and - a console window is only generated when the script uses standard - input or output. A script that uses STDWIN exclusively for its I/O - will have a working Apple menu and no extraneous File/Edit menus. - (This is because both stdwin and stdio try to initialize the - windowing environment; whoever gets there first owns the Apple menu.) - LIMITATIONS: a few recent additions to STDWIN for X11 have not yet - been added to the Mac version. There are no bitmap objects, and - the setwinpos() and setwinsize() methods are non--functional. - -- Because launching an application on the Mac is so tedious, you will - want to edit your program with a desk accessory editor (e.g., Sigma - edit) and test the changed version without leaving Python. This is - possible but requires some care. Make sure the program is a module - file (filename must be a Python identifier followed by '.py'). You - can then import it when you test it for the first time. There are - now three possibilities: it contains a syntax error; it gets a runtime - error (unhandled exception); or it runs OK but gives wrong results. - (If it gives correct results, you are done testing and don't need - to read the rest of this paragraph. :-) Note that the following - is not Mac-specific -- it's just that on UNIX it's easier to restart - the entire script so it's rarely useful. - - Recovery from a syntax error is easy: edit the file and import it - again. - - Recovery from wrong output is almost as easy: edit the file and, - instead of importing it, call the function reload() with the module - name as argument (e.g., if your module is called foo, type - "reload(foo)"). - - Recovery from an exception is trickier. Once the syntax is correct, - a 'module' entry is placed in an internal table, and following import - statements will not re-read the file, even if the module's initialization - terminated with an error (one reason why this is done is so that - mutually recursive modules are initialized only once). You must - therefore force re-reading the module with reload(), however, if this - happens the first time you try to import the module, the import statement - itself has not completed, and your workspace does not know the module - name (even though the internal table of moduesl does!). The trick is - to first import the module again, then reload it. For instance, - "import foo; reload(foo)". Because the module object already exists - internally, the import statement does not attempt to execute the - module again -- it just places it in your workspace. - - When you edit a module you don't have to worry about the corresponding - '.pyc' file (a "compiled" version of the module, which loads much faster - than the textual version): the interpreter notices that the '.py' file - has changed (because its modification time has changed) and ignores the - '.pyc' file. When parsing is successful, a new '.pyc' file is written; - if this fails (no write permission, disk full or whatever) it is - silently skipped but attempted again the next time the same module - is loaded. (Thus, if you plan to place a Python library on a read-only - disk, it is advisable to "warm the cache" by making the disk writable - and importing all modules once. The standard module 'importall' helps - in doing this.) |
