Converting Latex style files for use in Context

Converting Latex style files for use in Context

[Adam Tee]

Hi all,

I have an ebnf grammar which I need to put in a context doc and have a 
specific style file (ebnf.sty).  Is there an easy way to convert it for 
use in context.



Thanks

Adam

How should we know? I don't have ebnf.sty on my system so this is
probably not a well known package. If you provide some more
information (where the sty can be found, how an input looks like or
so) we might be able to help better.

Like all TeX related things you can find it in CTAN, exactly in

http://www.ctan.org/tex-archive/macros/latex209/contrib/misc/ebnf.sty

The file is old (1991) so i don't know if it would run with latex2e.
The code is very sort, mainly it redefineas a description enviromment.
I Think it wouldn't be very dificult define a new definition enviroment
for ENNF

well, not *all* TeX relatet stuff is on CTAN...

and incorrect (the last Cat is missing its backslash). And even with
this backslash, the formatting is strange. I'd suggest something like
this (warning: ugly(!!) LaTeX code ahead):

\begingroup 
   \catcode`\|=13
   \catcode`\<=13
    \gdef\EBNF
    {\list{???}%
      {%
        \def|{$\mid$}%
        \def\makelabel##1{<##1> ::=}%
        \def\Cat##1{$\langle${\it ##1\/}$\rangle$}
        \def<##1>{\Cat{##1}}
        \parsep=0pt \itemsep=\smallskipamount
        \leftmargin=\parindent \advance\leftmargin+2em
        \labelsep=0.5em \labelwidth=1.5em
        \raggedright
        \catcode`\|=13 
        \catcode`\<=13 
      }%
    }
\endgroup
 
\let\endEBNF\endlist

\documentclass{article}
\usepackage{calc}
\begin{document}

\begin{EBNF}
    \item[glue]       <dimen> [~`plus' <stretch>~] [~`minus' <stretch>~].
    \item[stretch]    <dimen> | <fil dimen>.
    \item[fil dimen]  <factor> (~`fil' | `fill' | `filll'~).
\end{EBNF}

\end{document}


which looks like this:

<glue>::= <dimen> [ ‘plus’ <stretch> ] [ ‘minus’ <stretch> ].
<stretch>::= <dimen>| <fil dimen>.
<fil dimen>::= <factor >( ‘fil’ | ‘fill’ | ‘filll’ ).

All right, you will agree that you can find *all*most all TeX relatet
stuff :-)
