[luatex] Core dump error
I'm having some problems using `\localleftbox` and `\localrightbox` in
LuaTeX 1.10 (the TeX Live 2019 Pretest) and GregorioTeX. In trying to
diagnose this problem, I stripped things down to this simple test document:
```
\documentclass{article}
\begin{document}
Something
\localleftbox{Hello}
%\localrightbox{Goodbye} % This one will trigger the error too.
Something
\end{document}
```
This document complies just fine with 1.07 (which shipped with TeX Live
2018). With 1.10, however, I get a core dump:
```
This is LuaTeX, Version 1.10.0 (TeX Live 2019)
restricted system commands enabled.

Did something change in `\localleftbox` and `\localrightbox` which I
should be aware of?

I almost always use synctex, so that's a personal possibility, but I'm also programming for others who might not. What about the `stop_run` callback?

Re: [luatex] First question: Retrieve *family* name of a font / the three main families
On 1/20/18 11:36 AM, Ulrike Fischer wrote: Well as I already wrote on tex.SX it is rather unclear what you mean by family and how you want to use it. The goal is to be able to pass the information to another program, LilyPond, and use it to set the fonts there so that there is some consistency in the look of documents which mix results from LuaTeX and LilyPond (and it happens automatically). Unlike LuaTex (and other TeX flavors) which permit mixing fonts as you've indicated, LilyPond doesn't. Instead it defines three font groups: roman, sans, and typewriter. Within those groups changes in weight, shape, etc. are automatically done within the same font family. I.e. if I define the roman font to be Century Schoolbook, then the bold text will always be the Century Schoolbook-Bold. If I define it to be Arial then bold will be Arial Bold. So far as I know, there is no way to do something like what you indicate is possible in LuaTeX within LilyPond. In this respect, selecting the font in LilyPond is like selecting a font in a "dumb" program like Word or OpenOffice. When Urs says he wants the font family, then, he's looking for that primary name which would allow a "dumb" program to select the normal, bold, italic, etc. font varieties from that same family. -- ✝ Br.

IIRC, otfinfo is also made available by TeXLive. In 2016 the Gregorio project started adding version information to our fonts and I modified our system-setup.bat (a script we provide to help diagnose installation problems) to make use of otfinfo in order to check that version information. I only would have done that if I felt it was reasonable to expect otfinfo to be available on Windows, i.e. TeXLive and/or MiKTeX installed it. -- ✝ Br.

[luatex] Strange behavior for io.popen
In working with the TeXLive 2017 pretest, we (the Gregorio developers)
came across what appears to be a bug in io.popen: it's passing the
statement `all commands are permitted` to the sh instance that it was
creating, resulting in an `all: command not found` error. After some
considerable testing (see conversation here:
https://github.com/gregorio-project/gregorio/issues/1362), we isolated
the problem to the `--shell-escape` switch. If the simple document
below is compiled *without* the switch, it is behaves as expected and is
able to retrieve the gregorio version number (gregorio is on the list of
commands permitted without shell-escape in texmf.cnf for TeXLive 2017).
When compiled with the switch, however, the error crops up and the
document reads `l is nil`.
```
\documentclass{article}
\begin{document}
\directlua{
f = io.popen('gregorio --version', 'r')
if f then
l = f:read('*l')
if l then
tex.print('got '..l)
else
tex.print('l is nil')
end
else
tex.print('f is nil')
end
}
\end{document}
```
Besides the original Ubuntu 16.04 system this was seen on, we've also
been able to confirm it on Gentoo, Mac 10.10 (Yosemite), and Windows 10
and so believe the problem to be platform independent.

[luatex] Lua interpreter difference between Windows and Mac
I'm writing a lua script which has the following code block: font_target = "greciliae.ttf" font_directory = kpse.find_file(font_target) print(font_directory) Given that greciliae.ttf is installed in $TEXMFLOCAL/fonts/truetype/public/gregoriotex, the code block works fine on my Mac (10.11.6) when executed by texlua (and I assume on other Unix flavors, though I haven't tested that yet). However, when I test the same code on a Windows (10) machine, font_directory ends up being nil. When I type `kpsewhich greciliae.ttf` at the command prompt on the Windows machine, I get the proper path returned, so I know that kpsewhich can find the file. If I switch font_target to a "gregoriotex.sty" (which is installed in $TEXMFLOCAL/tex/lualatex/gregoriotex/) font_directory returns the proper value on both machines. Thus I know that kpse.find_file does actually work, at least some of the time, on Windows. Why isn't kpse.find_file finding fonts that kpsewhich can find on Windows? Am I doing something wrong? Both machines are running version 0.95.0 (TeXLive 2016) of texlua. -- ✝ Br. Samuel, OSB St. Anselm’s Abbey Washington, DC (R. Padraic Springuel) PAX ☧ ΧΡΙΣΤΟΣ
[luatex] Change in behavior
As part of the GregorioTeX package, we have a Lua function which
rescales a particular distance register by multiplying it by an
arbitrary factor (the factor can be non-integer, so we cannot do this
math in TeX itself). Originally we wrote the function as this:
local function scale_space(factor)
local skip = tex.getskip('gre@skip@temp@four')
skip.width = skip.width * factor
-- should skip.stretch and skip.shink also be scaled?
end
However, we found that after updating our testing process to use TL2016
(and thus LuaTeX 0.95 instead of 0.80) the rescaling was no longer
happening. After some experimentation, we found that the following worked:
local function scale_space(factor)
local skip = tex.getskip('gre@skip@temp@four')
skip.width = skip.width * factor
tex.setskip('gre@skip@temp@four',skip)
-- should skip.stretch and skip.shink also be scaled?
end
This implies to me that the behavior of the function interface for token
registers changed at some point between these two versions. In 0.80 a
variable filled with a token register was linked to that register and
changes to the variable were reflected in the token register itself. In
0.95 the variable is not linked to the register and thus changes to the
variable are not communicated to the register unless and until that is
done so explicitly. Is my interpretation of the situation correct? If
so, when did this change occur and what is the best way for me to stay
abreast of these sort of changes.

[luatex] LuaLaTeX 0.95 and xcolor
The attached document compiles fine using LuaLaTeX 0.80 (TeXLive 2015), but under LuaLaTeX 0.95 (TeXLive 2016) an error is raised by the xcolor package stating that `gregoriocolor` is not defined. Both pdfLaTeX 3.14159265-2.6-1.40.16 (TeX Live 2015) and 3.14159265-2.6-1.40.17 (TeXLive 2016) compile the document fine.

[luatex] TexLive 2016 Pretest Bug: Paper
When using the TeXLive 2016 Pretest, the geometry package does not
appear to be able to change the paper size when using the LuaLaTeX
engine. The failure is silent (no error or warning).
For instance, if the default paper size is set to letter (as it is on my
system), then the following document will come out on letter paper:
\documentclass{article}
\usepackage{geometry}
\geometry{a4paper}
\listfiles
\begin{document}
Test
\end{document}
Test system is Linux Ubuntu 14.04.
My guess is that this has to do with the backend changes in LuaTeX 0.85.
