class PegLexer(RegexLexer): (source)

View In Hierarchy

This lexer is for Parsing Expression Grammars (PEG). Various implementations of PEG have made different decisions regarding the syntax, so let's try to be accommodating: * `<-`, `←`, `:`, and `=` are all accepted as rule operators. * Both `|` and `/` are choice operators. * `^`, `↑`, and `~` are cut operators. * A single `a-z` character immediately before a string, or multiple `a-z` characters following a string, are part of the string (e.g., `r"..."` or `"..."ilmsuxa`). .. versionadded:: 2.6

Inherited from RegexLexer:

Method get_tokens_unprocessed Split ``text`` into (tokentype, text) pairs.

Inherited from Lexer (via RegexLexer):

Method __init__ Undocumented
Method __repr__ Undocumented
Method add_filter Add a new stream filter to this lexer.
Method analyse_text Has to return a float between ``0`` and ``1`` that indicates if a lexer wants to highlight this text. Used by ``guess_lexer``. If this method returns ``0`` it won't highlight it in any case, if it returns ``1`` highlighting with this lexer is guaranteed.
Method get_tokens Return an iterable of (tokentype, value) pairs generated from `text`. If `unfiltered` is set to `True`, the filtering mechanism is bypassed even if filters are defined.
