jinja2.bccache.FileSystemBytecodeCache¶

class jinja2.bccache.FileSystemBytecodeCache(directory=None, pattern='__jinja2_%s.cache')[source]¶

A bytecode cache that stores bytecode on the filesystem. It accepts two arguments: The directory where the cache items are stored and a pattern string that is used to build the filename.

If no directory is specified a default cache directory is selected. On Windows the user’s temp directory is used, on UNIX systems a directory is created for the user in the system temp directory.

The pattern can be used to have multiple separate caches operate on the same directory. The default pattern is '__jinja2_%s.cache'. %s is replaced with the cache key.

>>> bcc = FileSystemBytecodeCache('/tmp/jinja_cache', '%s.cache')

This bytecode cache supports clearing of the cache using the clear method.
