Liquid::LocalFileSystem

This implements an abstract file system which retrieves template files named in a manner similar to Rails partials, ie. with the template name prefixed with an underscore. The extension “.liquid” is also added.

For security reasons, template paths are only allowed to contain letters, numbers, and underscore.

Example:

file_system = Liquid::LocalFileSystem.new(“/some/path”)

file_system.full_path(“mypartial”) # => “/some/path/_mypartial.liquid” file_system.full_path(“dir/mypartial”) # => “/some/path/dir/_mypartial.liquid”
