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 desision 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!B/usr/lib/python3/dist-packages/pygments/lexers/grammar_notation.pyrs rc@seZdZdZdZdgZdgZdgZdZdde j fd e fd e fd e fd e fd e fde fde fde fde fde fde fe eddefdejfde fdefdefdefgiZdS)rz Lexer for `IETF 7405 ABNF `_ (Updates `5234 `_) grammars. .. versionadded:: 2.1 ZABNFZabnfz*.abnfz text/x-abnf)ZALPHAZBITZCHARZCRZCRLFZCTLZDIGITZDQUOTEZHEXDIGZHTABZLFZLWSPZOCTETZSPZVCHARZWSPrz;.*$z(%[si])?"[^"]*"z%b[01]+\-[01]+\bz%b[01]+(\.[01]+)*\bz%d[0-9]+\-[0-9]+\bz%d[0-9]+(\.[0-9]+)*\bz%x[0-9a-fA-F]+\-[0-9a-fA-F]+\bz!%x[0-9a-fA-F]+(\.[0-9a-fA-F]+)*\bz\b[0-9]+\*[0-9]+z \b[0-9]+\*z\b[0-9]+\*\bsuffixz[a-zA-Z][a-zA-Z0-9-]+\bz(=/|=|/)z[\[\]()]\s+rN)rrrrrrrrZ _core_rulesrSingler r rr r rrrr r!r!r!r"rEs6 rc@seZdZdZdZdgZdgZgdZej ej BZ e de dgde jd fd e jfd e jfgd e jfd efdefdefdejfdejdfdejdfedddejfdejdfdeeejefdedfdefg dejdfdejfd ejfgd!ejdfdejfd"ejfgdedfd efd#efd$ej fgd%edfd&efd efd'eej eefd(ej!fgd)e jdfd*ee je j"e#e$d+d,fd-ee je j"fd.e jfgd/e jfe dd0e jfgd1 Z%d2S)3rzn For `JSpeech Grammar Format `_ grammars. .. versionadded:: 2.2 ZJSGFZjsgfz*.jsgf)zapplication/jsgfzapplication/x-jsgfz text/jsgfcomments non-commentsz /\*\*(?!/)documentation commentz/\*[\w\W]*?\*/z//.*z \A#JSGF[^;]*r';z [=|()\[\]*+]z/[^/]+/"stringz\{tag)importZpublicr$r%z grammar\b grammar namez(<)(NULL|VOID)(>)<rulenamez\w+|[^\s;=|()\[\]*+/"{<\w]+z#popz\\.z[^\\"]+z\}z[^\\}]+\.z[^;\s.]+>r#z([^.>]+)(\s*)(\.)z[^.>]+z\*/zB(^\s*\*?\s*)(@(?:example|see)\s+)([\w\W]*?(?=(?:^\s*\*?\s*@|\*/)))example)statez(^\s*\*?\s*)(@\S*)z[^*\n@]+|\w|\Wz\n\s*\*r) rr)r*r.r/r1r3r+r6N)&rrrrrrrrre MULTILINEUNICODEflagsrrZ Multiliner(ZPreprocrrr r ZFloatrDoubleZOtherrr ZReservedrr ZBuiltinZEscapeZ NamespaceZConstantSpecialrrr r!r!r!r"rs~             rc @steZdZdZdZdgZdgZdgZddej fde fd e fd e fd e e ee fd ejfd ej fdejfdefg iZdS)ruZ This lexer is for `Parsing Expression Grammars `_ (PEG).
