While the conditional commands in the html.perl package are great when
choosing which code to process depending on latex2html or LaTeX2e are
being used, I sometimes need conditional processing when processing
with LaTeX2e. I assume html.perl can't do general purpose conditional
processing with LaTeX2e?
I have a partially complete implementation of ifthen.perl to support
\ifthenelse{condition}{cond true commands}{cond false commands}
One thing that stymies me is that the parameter sent to
do_cmd_ifthenelse is delimited by the next \section/\subsection
command. This produces problems if you want to conditionally process a
section, i.e.
\ifthenelse{\boolean{dothissection}}
{
\section{This is a section that will be processed if dothissection is
true}
And it's contents.
}
{
\section{This is a section that will be processed if dothissection is
false}
And it's contents.
}
I assume that ifthenelse needs to be processed via
&substitute_meta_cmds since according to the documentation, these are
processed prior to splitting the input text into chunks at section
boundaries?
The other issue raised in a previous mail list posting by Ross is it
seems booleans are not guaranteed to expand in the same way in
latex2html than in LaTeX, I can live with/work around that, although
fairly simple set of commands like
\newboolean{condition}
\setboolean{condition}{true}
\boolean{condition}
in 1.70 of latex2html.pin always produce 0. I've sent the changes to
Ross to fix those bugs in \boolean processing. However, am I correct in
assuming latex2html-2002-2-1.tar.gz is still the latest release?
The link http://saftsack.fs.uni-bayreuth.de/~latex2ht/current/ from
www.latex2html.org lists all files as written on the 29th of November
2002, I assume the other ones cover releases in 1999 (i.e
latex2html-99.2beta8.tar.gz) and 2000 (latex2html-2K.1beta.tar.gz)?
Do I understand that to mean latex2html-2002-2-1.tar.gz does not change
it's name when updates have been made, or that no changes have been
made since the 2002-2-1 release?
I'm sorry for all the questions, but the version numbering in the name
of the tarball seems non-standard. Also, am I correct in assuming that
the CVS repository itself is not accessible but only a checked out
distribution accessible at
http://saftsack.fs.uni-bayreuth.de/~latex2ht/user/?
In any case, the changes I made to 1.70 of latex2html.pin are:
14415c14415,14417
< if (defined $global{$bool}) { $val= $global{$bool} }
---
> if (defined $global{"if$bool"}) {
> $val= $global{"if$bool"}
> }
14528c14530
< $global{"if$bool"} = (($val = ~/true/) ? 1 : 0);
---
> $global{"if$bool"} = (($val =~ /true/) ? 1 : 0);
Once ifthen.perl is a bit more functional, I'd like to contribute it to
the distribution.
Happy Holidays
