This module provides some utility functions to support installing Python libraries. These functions compile Python source files in a directory tree, allowing users without permission to write to the libraries to take advantage of cached byte-code files.
The source file for this module may also be used as a script to
compile Python sources in directories named on the command line or in
|dir[, maxlevels[, ddir[, force[, rx[, quiet]]]]])|
10. If ddir is given, it is used as the base path from which the filenames used in error messages will be generated. If force is true, modules are re-compiled even if the timestamps are up to date.
If rx is given, it specifies a regular expression of file names to exclude from the search; that expression is searched for in the full path.
If quiet is true, nothing is printed to the standard output in normal operation.
|[skip_curdir[, maxlevels[, force]]])|
sys.path. If skip_curdir is true (the default), the current directory is not included in the search. The maxlevels and force parameters default to
0and are passed to the compile_dir() function.
To force a recompile of all the .py files in the Lib/ subdirectory and all its subdirectories:
import compileall compileall.compile_dir('Lib/', force=True) # Perform same compilation, excluding files in .svn directories. import re compileall.compile_dir('Lib/', rx=re.compile('/[.]svn'), force=True)
