Class Parser

Declaration

Methods

• ▷ def __init__(self, tokens, libraries=None, builtins=None, origin=None)

  source link
• ▷ def add_library(self, lib)

  source link
• ▷ def compile_filter(self, token)

  Convenient wrapper for FilterExpression

  source link
• ▷ def delete_first_token(self)

  source link
• ▶ def error(self, token, e)

  Return an exception annotated with the originating token. Since the

  source link

  parser can be called recursively, check if a token is already set. This
  ensures the innermost token is highlighted if an exception occurs,
  e.g. a compile error within the body of an if statement.

• ▷ def extend_nodelist(self, nodelist, node, token)

  source link
• ▷ def find_filter(self, filter_name)

  source link
• ▷ def invalid_block_tag(self, token, command, parse_until=None)

  source link
• ▷ def next_token(self)

  source link
• ▶ def parse(self, parse_until=None)

  Iterate through the parser tokens and compiles each one into a node.

  source link

  If parse_until is provided, parsing will stop once one of the
  specified tokens has been reached. This is formatted as a list of
  tokens, e.g. ['elif', 'else', 'endif']. If no matching token is
  reached, raise an exception with the unclosed block tag details.

• ▷ def prepend_token(self, token)

  source link
• ▷ def skip_past(self, endtag)

  source link
• ▷ def unclosed_block_tag(self, parse_until)
