Hello,
I have already sent this mail one week ago, but I retry as I didn't find it in the archive. Sorry for duplicates.
The latex2html mailing list gets a lot of spam emails, and I don't have
a lot of spare time to sift them for the legitimate mails from people
who haven't subscribed.
So it's better to subscribe first, then send messages.
I try to use latex2html to convert a document with custom environments.
For example, here is a customized \input:
\RequirePackage{stack} \NewStack{reldir}{.} \newcommand\relinput[2]{% \Push{reldir}{\Stack{reldir}/#1}% \input{\Stack{reldir}/#2}% \Pop{reldir}}
No, customising \input in this way cannot not work with LaTeX2HTML.
This is because LaTeX2HTML builds a single large job from the main document, and its \input and \include'd files *before* starting to process macros and environments.
Since \relinput is seen as an ordinary macro, it will not be expanded to reveal the \input that it contains, until after the job files have been amalgamated. At that time, it is *too late* to add new material to be interpreted within the job.
However, if you just want to make an image of the file's (La)TeX contents...
First, I tried to let tex handle this command with:
&process_commands_in_tex (<<_RAW_ARG_CMDS_); relinput # {} # {} _RAW_ARG_CMDS_
... then this approach can be made to work, ...
But the file in question is said not to be found even if it exists (I don't know exactly why -- I guess it's because the generated files are in a different directory).
... but note that TeX processing takes place in a different directory to where your document sources are located.
Usually this is just one level deeper, so an extra '../' in the directory path should be sufficient.
Then, I tried to adapt the subroutine do_cmd_input in the following way,
but I have got the same problem.
$relinput_rep = ".";
First try testing using $relinput_rep = "..";
sub do_cmd_relinput {
local($_) = @_;
local($rep,$file,$output,$oldrep);
(s/\s*(.*)\s*\n/$rep =$1;''/s) unless (
(s/$next_pair_pr_rx/$rep=$2;''/eo)
||(s/$next_pair_rx/$rep=$2;''/eo));
(s/\s*(.*)\s*\n/$file =$1;''/s) unless (
(s/$next_pair_pr_rx/$file=$2;''/eo)
||(s/$next_pair_rx/$file=$2;''/eo));
local($after) = $_;
$oldrep = $relinput_rep;
$relinput_rep = "$relinput_rep$dd$rep";
$file = &revert_to_raw_tex("\\input{$relinput_rep$dd$file}\n") if $file;
if ($PREAMBLE) { &add_to_preamble('include',$file)}
elsif (!($file=~/^\s*$/)) {
$output = &process_undefined_environment('center'
, ++$global{'max_id'},"\\vbox{$file}");
}
$relinput_rep = $oldrep;
$output.$after;
}
Any idea?
If no other errors were reported, then I think you just need to sort out the path to the files to be read within this context.
Hard-coding $relinput_rep = ".."; is not the most robust solution, since it'll be incompatible with general settings for $DESTDIR .
More robust would be something like:
$relinput_rep = $RELINPUT_DIR||'..';
where, if necessary, you can set $RELINPUT_DIR as a Perl variable in an initialization file.
I've also got other questions: Can I add a custom directory with my own
perl subroutines? Where can I find a documentation on how to add personal
subroutines to latex2html (I tried to read the code, but a clear
documentation would be better)?
Initialization files are implemented for precisely this purpose. See the -init_file <filename> switch. You can use as many of these as you like; they'll be read, and their Perl coding interpreted, in the order in which they occur on the command-line.
There is a lot of documentation on this in the LaTeX2HTML chapter of the book: The LaTeX Web Companion (Addison-Wesley).
Thanks for your help,
Prakash
Hopefully you'll be able to get your jobs working correctly now.
It's great to see someone willing to tackle the Perl coding to get the job done.
Best regards,
Ross
