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
sys.path.
compile_dir(
dir[, maxlevels[,
ddir[, force[,
rx[, quiet]]]]])
Recursively descend the directory tree named by dir, compiling
all .py files along the way. The maxlevels parameter
is used to limit the depth of the recursion; it defaults to
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.
compile_path(
[skip_curdir[,
maxlevels[, force]]])
Byte-compile all the .py files found along 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 0 and 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)
