liquid.exts.filter_colon

module

liquid.exts.filter_colon

</>

Provides an extension to use colon to separate filter and its arguments

Jinja uses {{a | filter(arg)}}, but liquid uses {{a | filter: arg}}

Classes
  • FilterColonExtension — This extension allows colon to be used to separatethe filter and arguments, so that we can write django/liquid-style filters </>

Methods
  • __init_subclass__() — This method is called when a class is subclassed.</>
  • attr(name, lineno) (ExtensionAttribute) — Return an attribute node for the current extension. This is usefulto pass constants on extensions to generated template code. </>
  • bind(environment) (Extension) — Create a copy of this extension bound to another environment.</>
  • call_method(name, args, kwargs, dyn_args, dyn_kwargs, lineno) (Call) — Call a method of the extension. This is a shortcut for:meth:attr + :class:jinja2.nodes.Call. </>
  • filter_stream(stream) (Token) — Modify the colon to lparen and rparen tokens</>
  • parse(parser) (Union(node, list of node)) — If any of the :attr:tags matched this method is called with theparser as first argument. The token the parser stream is pointing at is the name token that matched. This method has to return one or a list of multiple nodes. </>
  • preprocess(source, name, filename) (str) — This method is called before the actual lexing and can be used topreprocess the source. The filename is optional. The return value must be the preprocessed source. </>
classmethod

__init_subclass__()

</>

This method is called when a class is subclassed.

The default implementation does nothing. It may be overridden to extend subclasses.

method

bind(environment) → Extension

</>

Create a copy of this extension bound to another environment.

method

preprocess(source, name, filename=None) → str

</>

This method is called before the actual lexing and can be used topreprocess the source. The filename is optional. The return value must be the preprocessed source.

method

parse(parser) → Union(node, list of node)

</>

If any of the :attr:tags matched this method is called with theparser as first argument. The token the parser stream is pointing at is the name token that matched. This method has to return one or a list of multiple nodes.

method

attr(name, lineno=None) → ExtensionAttribute

</>

Return an attribute node for the current extension. This is usefulto pass constants on extensions to generated template code.

::

self.attr('_my_attribute', lineno=lineno)
method

call_method(name, args=None, kwargs=None, dyn_args=None, dyn_kwargs=None, lineno=None) → Call

</>

Call a method of the extension. This is a shortcut for:meth:attr + :class:jinja2.nodes.Call.

generator

filter_stream(stream) → Token

</>

Modify the colon to lparen and rparen tokens
