Bug#929128: fonts-noto-cjk: not recognized by lualatex until mktexlsr

2019-06-09 Thread Ryutaroh Matsumoto
Hi Hilmar,

Thank you for your suggestion.
I filed "6GB real memory is used by lualatex even with small input"
issue at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=930292

It is independent of Japanese localization of lualatex.

Best regards,
Ryutaroh

Bug#929128: fonts-noto-cjk: not recognized by lualatex until mktexlsr

2019-06-09 Thread Norbert Preining
Hi

> (2) Run lualatex with the below LaTeX source and have error
> "Package fontspec Error: The font "NotoSerifCJKJPLight" cannot be found."

Yes, because luatexja preloads all the fonts defined in the noto-otf
preset:
\ltjpreset_declare_preset:nx{noto-otf}{
mc-m =  Noto~Serif~CJK~JP~Regular,
mc-bx = Noto~Serif~CJK~JP~Bold,
gt-d =  Noto~Sans~CJK~JP~Regular,
gt-bx = Noto~Sans~CJK~JP~Bold,
gt-u =  Noto~Sans~CJK~JP~Medium,
gt-eb = Noto~Sans~CJK~JP~Black,
mg-m =  Noto~Sans~CJK~JP~Black,
mc-l =  Noto~Serif~CJK~JP~Light,
__custom = false, __office = false, __noembed = false,
}

Thus it fails if the font is not installed.

I haven't seen the uplatex version of your document, but I guess you
load the fonts with the otf package. There the fonts are only necessary
when calling dvipdfmx, and thus only the actually needed fonts are
loaded.

I think this is neither a feature nor a bug, it is just that the two
systems work differently.

You can ask the luatexja maintainers to implement on-demand loading of
fonts, but I am not sure how feasible this is.


All the best

Yes, luatexja needs lualatex, you cannot use anything else.

You are right. The way to reproduce this issue (not related to mktexlsr)
is
(1) Install texlive-full and fonts-noto-cjk from experimental.
(2) Run lualatex with the below LaTeX source and have error
"Package fontspec Error: The font "NotoSerifCJKJPLight" cannot be found."
(3) Installation of fonts-noto-cjk-extra fixes the issue even though
no font from
fonts-noto-cjk-extra is used. XeLaTeX (with \usepackage[noto]{zxjafont}) and
uplatex (with \usepackage[unicode,noto-otc]{pxchfon}) produce the desired

I'm able to process your file using lualatex right now. Then I tried to
process it using uplatex and xelatex and both did not work. I always get
messages like

I guess the document class needs luatex. ;-)

thanks for your interest and comment. It is (in my opinion) a
well-known issue among Japanese LuaLaTeX users, and I can show a
even worse example (for your fun), which needs 6 GB of real RAM and
10 minutes to compile three lines, in the first time you process a

OK, after re-configuring my VM (put more RAM into it) and stopping a RAM
eating process I was able to compile your document. I guess your comment in

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=929128#40

is completely valid. The font needed by the document is
"NotoSerifCJKJPLight" and this font is provided by fonts-noto-cjk-extra,
not by fonts-noto-cjk. I just checked the package from experimental.

Bug#929128: fonts-noto-cjk: not recognized by lualatex until mktexlsr

2019-05-26 Thread Ryutaroh Matsumoto
Hi Hideki,
thanks for your kind comment.

My understanding is that it is related to luatexja-preset.sty
(or Japanese localization of LuaLaTeX).
When we run the "report-bug" against a tex package, it tells us that

> -- Package-specific info:
> IMPORTANT INFORMATION: We will only consider bug reports concerning

>*** The Debian TeX Team is *not* a LaTeX Help Desk ***

So, provided that the issue is in luatexja-preset.sty,
the Debian TeX team may unwelcome it...
Is it OK to reopen it (and maybe reassign it to texlive-lang-japanese)?

If I understand the issue correctly,
the problem is that

* lualatex + luatexja-preset.sty requires "NotoSerifCJKJPLight"
  even when "NotoSerifCJKJPLight" font is not used in a document,
  while uplatex or xelatex (with their localizations files) does
  not require "NotoSerifCJKJPLight" unless it is used.
 
But the above behavior seems a kind of "design"...
And a solution can be inclusion of all CJK font files into
"fonts-noto-cjk", which suggests that this issue should be filed
against "fonts-noto-cjk".

Your feedbacks are welcome.

Ryutaroh

Sorry for brevity, traveling with daughter intercontinental.

It is a dpkg trigger on /u/s/fonts as far as I remember. That is, if files are 
installed there the postins if tex-common should be called and the necessary

I will look into it and see what is the reason, my guess is that it is not

For the case of "fonts-ipaex-mincho",
"apt-get install texlive-full" installs "fonts-ipaex-mincho"
and "texlive-fonts-recommended" by the dependency.
Then the "postinst" in "texlive-fonts-recommended"
runs "update-texmf-config map", which in turn runs
"mktexlsr".

That's my understanding.

Hi Hideki,

mktexlsr in installation of a font package is executed
as a trigger to tex-common as we often see
"Processing triggers for tex-common", if I understand it
correctly.

fonts-ipaexfont-mincho package installs its fonts to
/usr/share/fonts/opentype, and the font file is recognized
by uplatex and lualatex after its installation.

"postinst" scripts are very different between
fonts-ipaexfont-mincho and fonts-noto-cjk.

My guess is that mimicing fonts-ipaexfont-mincho
in the postinst of fonts-noto-cjk addresses this issue.
If my guess is correct, fonts-noto-cjk-extra should also
have the same issue.

Dear Maintainer,

Font Noto CJK can be used by lualatex (in texlive-latex-base).
But lualatex does not recognize the Noto fonts until one executes
mktexlsr.

I suggest to execute mktexlsr in the installation of fonts-noto-cjk
if mktexlsr is installed.
