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 Windows will return one of: win-amd64 (64bit Windows on AMD64 (aka x86_64, Intel64, EM64T, etc) win-ia64 (64bit Windows on Itanium) win32 (all others - specifically, sys.platform is returned) For other non-POSIX platforms, currently just returns 'sys.platform'. �ntz bit (� �)�amd64z win-amd64�itaniumzwin-ia64�_PYTHON_HOST_PLATFORM�posix�uname�/� � �_�-N� �linuxz%s-%s�sunosr �5�solarisz%d.%s� � i����32bitl ���� �64bitz.%s� �irix�aixz%s-%s.%s� �cygwinz[\d.]+�darwinz%s-%s-%s���)�os�name�sys�version�find�platform�len�lower�environ�hasattrr �replace�int�maxsize�re�compile�ASCII�match�group� _osx_supportZdistutils.sysconfig�get_platform_osx� sysconfig�get_config_vars)�prefix�i�j�look�osname�host�releaser' �machine�bitness�rel_re�mr6 � distutils� rF �3/opt/alt/python35/lib64/python3.5/distutils/util.py� get_platform sX # ( rH c C s� t j d k r | S| s | S| d d k r= t d | � � | d d k r] t d | � � | j d � } x d | k r� | j d � qo W| s� t j St j j | � S)a� 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.

W| S) a Split a string up according to Unix shell-like rules for quotes and backslashes. 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. Returns a list of words.

Such actions are special because they are disabled by the 'dry_run' flag. This method takes care of all that bureaucracy for you; all you have to do is supply the function to call and an argument tuple for it (to embody the "external action" being performed), and an optional message to print.

'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 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. zbyte-compiling is disabled.Nr )�mkstempz.py)�mktempz$writing byte-compilation script '%s'�wz2from distutils.util import byte_compile files = [ z, z] z� byte_compile(files, optimize=%r, force=%r, prefix=%r, base_dir=%r, verbose=%r, dry_run=0, direct=1) r z-Or z-OOr z removing %s)r2 r r � optimizationz1invalid prefix: filename %r doesn't start with %rzbyte-compiling %s to %sz%skipping byte-compilation of %s to %s���)"r& �dont_write_bytecoder � __debug__Ztempfiler� � ImportErrorr� r rz r$ �fdopen�open�writerP �map�repr�close� executable�insertr r� rM � py_compiler2 � importlib�util�cache_from_sourcer* rK rO �basenamer �debug)Zpy_files�optimizeZforcer: Zbase_dirr~ r Zdirectr� Z script_fdZ script_namer� Zscript�cmdr2 �fileZopt�cfile�dfileZ cfile_baserF rF rG � byte_compile@ sn " # r� c C s" | j d � } d } | j | � S)z�Return a version of the string escaped for inclusion in an RFC-822 header, by ensuring there are 8 spaces space after each newline. � � r z z )rL rP )�header�linesrJ rF rF rG � rfc822_escape� s r� c C sw | s d Sd d l m } m } Gd d � d | � } | d k rN | d � } | | d | �} | j | d d �d S) a Invoke 2to3 on a list of Python files.
