\section{\module{compileall} ---
Byte-compile Python libraries}
\declaremodule{standard}{compileall}
\modulesynopsis{Tools for byte-compiling all Python source files in a
directory tree.}
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
\code{sys.path}.
\begin{funcdesc}{compile_dir}{dir\optional{, maxlevels\optional{,
ddir\optional{, force\optional{,
rx\optional{, quiet}}}}}}
Recursively descend the directory tree named by \var{dir}, compiling
all \file{.py} files along the way. The \var{maxlevels} parameter
is used to limit the depth of the recursion; it defaults to
\code{10}. If \var{ddir} is given, it is used as the base path from
which the filenames used in error messages will be generated. If
\var{force} is true, modules are re-compiled even if the timestamps
are up to date.
If \var{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 \var{quiet} is true, nothing is printed to the standard output
in normal operation.
\end{funcdesc}
\begin{funcdesc}{compile_path}{\optional{skip_curdir\optional{,
maxlevels\optional{, force}}}}
Byte-compile all the \file{.py} files found along \code{sys.path}.
If \var{skip_curdir} is true (the default), the current directory is
not included in the search. The \var{maxlevels} and
\var{force} parameters default to \code{0} and are passed to the
\function{compile_dir()} function.
\end{funcdesc}
