c óf — t | j « }|j | « |j S )a Returns a set of all variables in the AST that will be looked up from
|
|||
|
|
the context at runtime. Because at compile time it's not known which
|
|||
|
|
variables will be used depending on the path the execution takes at
|
|||
|
|
runtime, all variables are returned.

.. admonition:: Implementation
|
|||
|
|
|
|||
|
|
Internally the code generator is used for finding undeclared variables.
|
|||
|
|
This is good to know because the code generator might raise a
|
|||
|
|
:exc:`TemplateAssertionError` during compilation and as a matter of
|
|||
|
|
fact this function can currently raise that exception as well.

|
|||
|
|
iterator over all the hardcoded template extensions, inclusions and
|
|||
|
|
imports. If dynamic inheritance or inclusion is used, `None` will be
|
|||
|
|
yielded.

>>> list(meta.find_referenced_templates(ast))
|
|||
|
|
['layout.html', None]
|
|||
|
|
|
|||
|
|
This function is useful for dependency tracking. For example if you want
|
|||
|
|
to rebuild parts of the website after a layout template has changed.
