committed to tl, r42672.

yes, regression testing is desperately needed.

I've found some issues when I tried to compile my older document which uses minted for syntax highlighting - calc package failed to load correctly. It uses \@for\sometempvar:=...\do{} command, and as I've found, the : had wrong catcode, so it was seen as part of the command name, instead of delimiter.

After some research I've found that tex4ht saves catcodes before the usepackage.4ht is included, and restores them afterwards. Expl3 is used in fontspec patch and it somewhat messed this catcode business.

It should be fixed by newest commit.

Regarding upgrading, I think it would be great to have some regression testing. To test if testing documents compile without compilation errors and that the resulting files contain correct XML. Both could be done with Lua, in order to be portable.

it was my mistake. you did mention it in the first changelog entry, but i failed to check that. sorry. committed to tl, along with the new html4.4ht (42665, 42666)

another excellent medium-term project would be to go through the diffs between tl and current tex4ht and ensure it is ok (or make it ok) to update. i think most are due to generic changes long ago (perhaps made by eitan).

Karl, I just updated TL and figured out that I didn't mention usepackage.4ht as a modified file in the changelog, so it wasn't updated - it patches Fontspec upon loading, it doesn't work without it. That was my mistake, sorry.

that's what i thought too, but doing a grep, i see that info4ht.4ht (tex4ht-info.tex) shows \input mktex4ht.4ht being used in an example template (nowhere else). should actually read that file sometime :).

Thanks Karl. mktex4ht.4ht is used for generating seeding .4ht files from the literate sources, so it probably doesn't need to be in TL. On the other hand, it already is in TL, some prehistoric version obviously, so it is probably good to make an update.

make clean got me going again. whew.

committed fontspec files
fontspec-4ht.lua fontspec-luatex.4ht fontspec-xetex.4ht fontspec.4ht
to tl, r42654. also committed mktex4ht.4ht, which i never had before. maybe that was a mistake? or maybe it doesn't matter?

It compiles without problems on my machine, maybe a issue with some temp files? I will try it tomorrow on a different computer.

sorry about the double inclusion. i didn't think i had changed anything but the word transposition in the filename. oh well.

anyway, with current repo (rev 210), i get:

! Undefined control sequence.
\at:startdoc ...f }\HtmlEnv \a:Preamble \a:PROLOG
(followed by many more errors)

when processing tex4ht-4ht.tex. help?

It was included twice after the change. I fixed that, also I've found that configuration hooks were included only for xetex. it should be fixed as well now. Finally, I moved luatex definitions to fontspec-luatex.4ht.

i felt the need to rename xetex-fontspec.4ht to fontspec-xetex.4ht (committed in r209 along with administrivia). michal, can you check that all is still working as intended before i commit to tl, please?

I've just pushed code to the repo. It works for both LuaTeX and XeTeX now. I've tried it with Latin, Greek, Cyrilics and Devanagari scripts, sample file is attached.

I have an issue with the change to tex4ht-html4.tex, the configurations aren't saved to html4.4ht. I guess that it is related to removal of mktex4ht.4ht generation from tex4ht-4ht.tex. When I add command \lit{fontspec} to mktex4ht.4ht manually, then the configurations are saved. But they aren't executed anyway.

No, this is just a proof of concept at the moment. I was busy last week, I will try to make some more testing in the near future and then update the sources if everything works nicely.

Thanks to Deimi I was able to pass "new-accents" option directly from Fontspec configuration, modified usepackage.4ht is attached.

As we recently found the way how to alter the package loading (using usepackage.4ht), I've created small configuration for the Fontspec package. Basically, what is needed is to prevent Fontspec from loading the EU1 or EU2 font encodings and to prevent loading of OpenType fonts. It works only with LuaLaTeX at the moment, XeLaTeX still tries to load the fonts.

The example file can be called using

make4ht -ulm draft luaotfloadpok.tex new-accents

The `new-accents` option is important, you would get bunch of errors otherwise. It should be possible to put

\edef\Preamble{\Preamble,new-accents}

somewhere, but when I do that in usepackage.4ht, then compilation fails with stack overflow, and in fontspec.4ht it doesn't have any effect.

One thing that doesn't work are font styles from the .htf files, resp. it doesn't work when you load a font with \setmainfont. So I put basic configuration for \textit and similar commands to fontspec.4ht, which isn't really clean, but this is just sample, so I hope it is OK.

Any comments are highly welcome.

We need to write fontspec.4ht for use with xelatex. This is a big job!
