This is used mainly to distinguish platform-specific build directories and platform-specific built distributions. Typically includes the OS name and version and the architecture (as supplied by 'os.uname()'), although the exact information included depends on the OS; eg. for IRIX the architecture isn't particularly important (IRIX only runs on SGI hardware), but for Linux the kernel version isn't particularly important. Examples of returned values: linux-i586 linux-alpha (?) solaris-2.6-sun4u irix-5.3 irix64-6.2 For non-POSIX platforms, currently just returns 'sys.platform'. t posixt unamet /t t t _i t linuxs %s-%st sunosi t 5t solariss %d.%si i i t irixt aixs %s-%s.%si t cygwins [\d.]+s %s-%s-%sN( t ost namet hasattrt syst platformR t osnamet hostt releaset versiont machinet stringt lowert replacet intt ret compilet rel_ret matcht mt group( R R R R R R R ( ( t$ /usr/lib/python2.4/distutils/util.pyt get_platform s0 ! *c C s t i d j o | Sn | p | Sn | d d j o t d | n | d d j o t d | n t i | d } x d | j o | i d q W| p t i Sn t t i i | S( s Return 'pathname' as a name that will work on the native filesystem, i.e. split it on '/' and put it back together again using the current directory separator. Needed because filenames in the setup script are always supplied in Unix style, and have to be converted to the local convention before we can actually use them in the filesystem.

In short: words are delimited by spaces, as long as those spaces are not escaped by a backslash, or inside a quoted string. Single and double quotes are equivalent, and the quote characters can be backslash-escaped. The backslash is stripped from any two-character escape sequence, leaving only the escaped character. The quote characters are stripped from any quoted string.

Such actions are special because they are disabled by the 'dry_run' flag.

'py_files' is a list of files to compile; any files that don't end in ".py" are silently skipped. 'optimize' must be one of the following: 0 - don't optimize (generate .pyc) 1 - normal optimization (like "python -O") 2 - extra optimization (like "python -OO") If 'force' is true, all files are recompiled regardless of timestamps. The source filename encoded in each bytecode file defaults to the filenames listed in 'py_files'; you can modify these with 'prefix' and 'basedir'. 'prefix' is a string that will be stripped off of each source filename, and 'base_dir' is a directory name that will be prepended (after 'prefix' is stripped). You can supply either or both (or neither) of 'prefix' and 'base_dir', as you wish. If 'dry_run' is true, doesn't actually do anything that would affect the filesystem. Byte-compilation is either done directly in this interpreter process with the standard py_compile module, or indirectly by writing a temporary script and executing it. Normally, you should let 'byte_compile()' figure out to use direct compilation or not (see the source for details). The 'direct' flag is used by the script generated in indirect mode; unless you know what you're doing, leave it set to None. i ( s mkstemps .py( s mktemps$ writing byte-compilation script '%s't ws2 from distutils.util import byte_compile files = [ s , s ] s byte_compile(files, optimize=%r, force=%r, prefix=%r, base_dir=%r, verbose=%r, dry_run=0, direct=1) i s -Oi s -OORl s removing %s( s compileit ct os1 invalid prefix: filename %r doesn't start with %rs byte-compiling %s to %ss% skipping byte-compilation of %s to %sN(/ t directRY t __debug__t optimizet tempfilet mkstempt script_fdt script_namet ImportErrort mktempRj Rk Rl R t fdopent scriptt opent writeR R- t mapt reprt py_filest forceRO t base_dirRm t closeR t executablet cmdt insertt spawnRn R) t py_compileR t filet cfilet dfileR^ R& R, t basenamet cfile_baset newert debug( R R R RO R Rm Rl R R R R R R R R R R R R ( ( R! t byte_compile= s` & c C sB t i | d } t t i | } t i | d d d } | S( s Return a version of the string escaped for inclusion in an RFC-822 header, by ensuring there are 8 spaces space after each newline. s i R N( R R' t headert linesR RZ R- ( R R ( ( R! t rfc822_escape s ( t __doc__t __revision__R R R R t distutils.errorsR8 t distutils.dep_utilR t distutils.spawnR t distutilsRj R" R.
