First we have the \type{\startbnfgrammar} and \type{\stopbnfgrammar} -%D pairs, which are of course used to delimit \BNF\ grammars. We would like to -%D define \type{\startbnfgrammar} as \type{\def\startbnfgrammar[#1]}, but a bug -%D in \CONTEXT\ prevents us from doing this, as the first character in the -%D grammar may be active, for example \type{<}, but while checking for the -%D presence of \type{[}, it gets ruined. A way around it is of course to -%D require that the user pass an empty \type{[]} pair, and we will use this -%D method at the moment. - -\def\complexstartbnfgrammar[#1]% - {\endgraf\nobreak\medskip - \begingroup - \setupbnfgrammar[#1]% - \chardef\bnfsinglequote=`' - \defineactivecharacter : {\@@bnfis} - \defineactivecharacter | {\@@bnfoption} - \defineactivecharacter " % - {\thinspace\bgroup\@@bnfterminalstart\setupinlineverbatim% - \defineactivecharacter " {\@@bnfterminalstop\egroup\thinspace}} - \defineactivecharacter ' % - {\thinspace\bgroup\@@bnfterminalstart\setupinlineverbatim% - \defineactivecharacter ' {\@@bnfterminalstop\egroup\thinspace}} - \catcode`<=13 - \let\par=\bnfgrammarline - \obeylines} - -\def\stopbnfgrammar{\medbreak\checknextindentation[\@@bnfindentnext]} - -\definecomplexorsimpleempty\startbnfgrammar - -%D \macros -%D {<>,bnfgrammarrule} -%D -%D We need a couple more macros to deal with the interior of a \BNF\ grammar. -%D \type{\<>} is used for non||terminals, and \type{\bnfgrammarrule} is used -%D later on in \type{\bnfgrammarswitch} for continuing a line. - -\def\<#1>{\leavevmode\hbox{\@@bnfnonterminalstart#1\/\@@bnfnonterminalstop}} - -\bgroup - \catcode`<=13 - \global\let<=\< - \gdef\bnfgrammarrule<#1>{\endgraf\indent\<#1>} -\egroup - -%D \macros -%D {bnfgrammarline, bnfgrammarswitch, bnfgrammarcont} -%D -%D These macros deal with the ending of a line in a grammar. -%D \type{\bnfgrammarline} is called whenever a new line begins, and invokes -%D \type{\bnfgrammarswitch} to determine what to do next. If the next token is -%D \type{\<}, we will call upon \type{\bnfgrammarrule} to deal with the new -%D rule. If it is \type{\stopbnfgrammar}, we end the top||level group, and let -%D it process \type{\stopbnfgrammar} afterwards.
