jinja2.sandbox.ImmutableSandboxedEnvironment.lex¶

ImmutableSandboxedEnvironment.lex(source, name=None, filename=None)¶

Lex the given sourcecode and return a generator that yields tokens as tuples in the form (lineno, token_type, value). This can be useful for extension development and debugging templates.

This does not perform preprocessing. If you want the preprocessing of the extensions to be applied you have to filter source through the preprocess() method.
