Not possible to use mylatex.ltx with xelatex #15
Comments
|
It probably works to set to OT1 in the format and back to TU in everyjob, combined with not preloading fonts: could you test
|
|
The patched latex.ltx appears to work: generation of format defining macro |
|
The original had not issue with lualatex. The patch seems to treat xelatex and lualatex engine alike. Is anything lost on lualatex side by so-doing? |
|
luatex may not give an error but I don't think it can work, to load an opentype font it would go through luaotfload and that lua state is not saved in the format so even if you don't get an error it's probably in an unstable state when it restarts. No time to test now, If you do any tests feel free to comment here. I'll look later. |

I was going to test luatex with OpenType fonts, but already xetex fails, even with patch from your comment \documentclass{article}
\def\abc{abc}
\usepackage{fontspec}
\setmainfont{Hoefler Text}% I am on a Mac
\begin{document}
\end{document}produces (with patched mylatex.ltx) $ xetex -ini \&xelatex mylatex.ltx abc

For info, minimal testing of lualatex with non-patched mylatex.ltx works. File abc.tex: \documentclass{article}
\def\abc{abc}
\usepackage{fontspec}
\setmainfont{Hoefler Text}
\begin{document}

yes I was going to say the patch only makes the bare minimum fonts that
latex itself loads "safe" for initex.
If you have packages loading opentype (or in luatex loading luacode) they
simply can't be loaded in to a format so you need to use the
%mylatex
comment to stop the format preload mid-preamble and then put any such lua
and font code after the comment

does work).

How do I trigger luacode with luatex? simply loading |
|
I actually meant any lua code, if you have
\directlua{require('my-lu-file'}}
in the preamble then the lua code will be loaded but not saved in the
format and not-reloladed when the document using teh format is used, so you
need
%mylatex
\directlua{require('my-lu-file'}}
so it happens later. or
\AtBeginDocument{ \directlua{require('my-lu-file'}}
so the lua call is saved in macro token memory in the format or .....

I see, thanks for explaining, not being a practitioner of lua, the obvious escaped me... |
|
Hey, came here trying to make a precompiled preamble with XeLaTeX. The above patch worked for me. Is there a reason for not making it the default? |
|
@Guekka mostly just that I haven't really updated mylatex.ltx ever. I'm not sure the patch really is useful in many contexts, most xelatex files will load some opentype fonts in the preamble, so it is rather limited what you can really save in a custom format without danger of changing the formatting somewhere. But I left this issue open, perhaps I could be persuaded... xetex is a bit easier to make work than luatex, as it is "just" the fonts you can not dump. in luatex you can not dump lua state either and that is much harder to avoid. |
|
Well, this patch allowed me to precompile my preamble. It is 500 lines long, and I only had to move two lines to another file. So I cannot speak for luatex, but it would be a welcome addition for xetex. |
|
@Guekka I suppose so, I'll see what I can do. I had thought that mylatex wasn't that useful in modern times (I wrote it for friends using old MSDOS implementations (when I had a Sun 3) and this saved about 5 minutes per run at the time:-) But I agree in today's less patient world, saving a couple of seconds is still worth it... (it is likely to be more than that if you use tikz) |
|
@davidcarlisle Hi David, only to mention that mylatex is used in preview.sty and the Emacs/AUCTeX system so changes to it should preferably be tested against these contexts and signaled to their maintainers before roll-out in case something is not backwards compatible. By the way Emacs/AUCTeX goes to certain lengths to make sure mylatex can be used with filenames having spaces or non-ascii characters so in particular if |
|
@davidcarlisle my wording is a bit confused (as a rule in this whole thread, again) and I meant to say that Emacs/AUCTeX uses the preview.sty + mylatex.ltx combination, not that preview.sty relied on mylatex, sorry. edit : damn'it, again I am not precise : Emacs/AUCTeX does that only optionally. |
|
@jfbu noted. The only change (should) be to make cases that don't work at all currently with xetex work, so compatibility shouldn't be an issue but tex being tex it is never that simple:-) |

Hi, Consider the following examples: --- abc.tex --- --- abc.ini --- Make a subdirectory named "build" by Then the following command leads to error: However, any of the following variants runs without error: Is there any fix or workaround for this error? (Whom (where) should I ask about this issue? Here? Lualatex developers? Luatex developers?) |
|
@ikumikeita this is the right repository, but the wrong issue thread as the issues with luatex and xetex are very different, please keep this one to xetex. With luatex, it is very hard (with or without So feel free to open issues here for LuaTeX if only as a place of recording issues, but the issues may remain unresolved. That is just the way it is.
