In order to maximize a number of targets of this lexer, let's decide some designs: * We don't distinguish `Terminal Symbol`. * We do assume that `NonTerminal Symbol` are always enclosed with arrow brackets. * We do assume that `NonTerminal Symbol` may include any printable characters except arrow brackets and ASCII 0x20. This assumption is for `RBNF `_. * We do assume that target notation doesn't support comment. * We don't distinguish any operators and punctuation except `::=`. Though these decision making might cause too minimal highlighting and you might be disappointed, but it is reasonable for us. .. versionadded:: 2.1 ZBNFZbnfz*.bnfz text/x-bnfrootz(<)([ -;=?-~]+)(>)z::=z[^<>:]+.N)__name__ __module__ __qualname____doc__namealiases filenames mimetypesrrr Classr rtokensr"r"D/tmp/pip-unpacked-wheel-7eq1ciah/pygments/lexers/grammar_notation.pyrs c@seZdZdZdZdZdgZdgZdgZdZ dd e j fd e fd e fd e fd e fde fde fde fde fde fde fde fee ddefdejfde fdefdefdefgiZdS)rz Lexer for IETF 7405 ABNF.
