|
+"""Append module search paths for third-party packages to sys.path.
|
|
|
+
|
|
|
+****************************************************************
|
|
|
+* This module is automatically imported during initialization. *
|
|
|
+****************************************************************
|
|
|
+
|
|
|
+In earlier versions of Python (up to 1.5a3), scripts or modules that
|
|
|
+needed to use site-specific modules would place ``import site''
|
|
|
+somewhere near the top of their code. Because of the automatic
|
|
|
+import, this is no longer necessary (but code that does it still
|
|
|
+works).
|
|
|
+
|
|
|
+This will append site-specific paths to the module search path. On
|
|
|
+Unix, it starts with sys.prefix and sys.exec_prefix (if different) and
|
|
|
+appends lib/python<version>/site-packages as well as lib/site-python.
|
|
|
+It also supports the Debian convention of
|
|
|
+lib/python<version>/dist-packages. On other platforms (mainly Mac and
|
|
|
+Windows), it uses just sys.prefix (and sys.exec_prefix, if different,
|
|
|
+but this is unlikely). The resulting directories, if they exist, are
|
|
|
+appended to sys.path, and also inspected for path configuration files.
|
|
|
+
|
|
|
+FOR DEBIAN, this sys.path is augmented with directories in /usr/local.
|
|
|
+Local addons go into /usr/local/lib/python<version>/site-packages
|
|
|
+(resp. /usr/local/lib/site-python), Debian addons install into
|
|
|
+/usr/{lib,share}/python<version>/dist-packages.
|
|
|
+
|
|
|
+A path configuration file is a file whose name has the form
|
|
|
+<package>.pth; its contents are additional directories (one per line)
|
|
|
+to be added to sys.path. Non-existing directories (or
|
|
|
+non-directories) are never added to sys.path; no directory is added to
|
|
|
+sys.path more than once. Blank lines and lines beginning with
|
|
|
+'#' are skipped. Lines starting with 'import' are executed.
|
|
|
+
|
|
|
+For example, suppose sys.prefix and sys.exec_prefix are set to
|
|
|
+/usr/local and there is a directory /usr/local/lib/python2.X/site-packages
|
|
|
+with three subdirectories, foo, bar and spam, and two path
|
|
|
+configuration files, foo.pth and bar.pth. Assume foo.pth contains the
|
|
|
+following:
|
|
|
+
|
|
|
+ # foo package configuration
|
|
|
+ foo
|
|
|
+ bar
|
|
|
+ bletch
|
|
|
+
|
|
|
+and bar.pth contains:
|
|
|
+
|
|
|
+ # bar package configuration
|
|
|
+ bar
|
|
|
+
|
|
|
+Then the following directories are added to sys.path, in this order:
|
|
|
+
|
|
|
+ /usr/local/lib/python2.X/site-packages/bar
|
|
|
+ /usr/local/lib/python2.X/site-packages/foo
|
|
|
+
|
|
|
+Note that bletch is omitted because it doesn't exist; bar precedes foo
|
|
|
+because bar.pth comes alphabetically before foo.pth; and spam is
|
|
|
+omitted because it is not mentioned in either path configuration file.
|
|
|
+
|
|
|
+After these path manipulations, an attempt is made to import a module
|
|
|
+named sitecustomize, which can perform arbitrary additional
|
|
|
+site-specific customizations. If this import fails with an
|
|
|
+ImportError exception, it is silently ignored.
