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 BNFbnfz*.bnfz text/x-bnfrootz(<)([ -;=?-~]+)(>)z::=z[^<>:]+.N)__name__ __module__ __qualname____firstlineno____doc__namealiases filenames mimetypesrrr Classrrtokens__static_attributes__r3lib/third_party/pygments/lexers/grammar_notation.pyrrsg6 DgG II  " k4::{ ; =X   4L   Fr*rc\rSrSrSrSrSrS/rS/rS/r Sr S S \ R4S \ 4S \ 4S \ 4S\ 4S\ 4S\ 4S\ 4S\4S\4S\4S\4\"\ SS9\4S\R$4S\4S\4S\4S\4/0rSrg)rBzu Lexer for IETF 7405 ABNF.
