No, no.. It's really just that i don't have this in roff.
And no, i was impressed from Eckel's ?Thinking in Java? style,
which was so different to all the rest. (Unfortunately that made
me buy his ?Thinking in C++? one or two years later and that
wasn't really it.) Everybody goes the spiral staircase, so to
say. But on Tucholsky's "talking writing silence" i'm on two at
most. ^.^
Whereas the styles are pretty basic, the really great thing on my
TeX package was that almost everything was hookable; builtin:
% 5 (default) styles. The numbered (inside) ones are ok for up to 9999 lines
\def\@verbatim@I{\hbox{}}% I = EMPTY
\def\@verbatim@II{% II = Numbered; number inside document;
{\smallest\it\hbox to 3em{\hfill\number\@count@verbatimno}\hbox to.84em{}}%
}
\def\@verbatim@III{% III = Numbered; number shifted to the left margin
\llap{{\smallest\it\number\@count@verbatimno}\hbox to.84em{}}%
}
\def\@verbatim@IV{% IV = black border left; border inside document
\vbox{\kern-3pt\vstrutbox{3}}\hbox to.84em{}%
}
\def\@verbatim@V{% V = black border left; border shifted to the left margin.
\llap{\vbox{\kern-3pt\vstrutbox{3}}\hbox to.84em{}}%
}
A default to be chosen from by simple command
\def\setVerbatimStyle#1{%
\def\@@value{#1}\def\@@value@{I}%
\ifx\@@value\@@value@%
\setHookVerbatimStyle{\@verbatim@I}%
..
}
\setVerbatimStyle{III}% Default is III
But you could adjust a lot of even those by doing some hooks
% Hooks
\def\setHookVerbatimPre#1{\gdef\@hook@verbatim@pre{#1}}%
\setHookVerbatimPre{\tt}%
\def\setHookVerbatimAfter#1{\gdef\@hook@verbatim@after{#1}}%
\setHookVerbatimAfter{}%
\def\setHookVerbatimStyle#1{% set in the style-section below
\gdef\@verbatim@baseStyle{%
\global\advance\@count@verbatimno by\TRUE\relax%
\hSkip{\@verbatim@leftindent}{#1}%
}%
% one can choose "local" styles. this is used to restore the global
\global\let\@hook@verbatim@style\@verbatim@baseStyle%
}%
% Dimen
\def\setVerbatimLeftIndent#1{\gdef\@verbatim@leftindent{#1}}%
\setVerbatimLeftIndent{0pt}%
(I was sooo proud of that stuff and even wanted to write a book.
Maybe good that the c't magazine distributed a virus on CD in
a program called Street Graphics or so and that i forgot my PGP
password to restore from backup.)
