How to compile

[adaldo]

Sorry if it sounds noob-ish, but could you please explain how compile the files in this repo to obtain a luatex.sty?

[josephwright]

There's nothing here that makes luatex.sty: you can do tex luatex85.ins to get luatex85.sty out of luatex.dtx.

[josephwright]

Normally you really shouldn't need to do this!

[adaldo]

Thanks! The first one worked, so now I have a luatex85.sty. On the second one: do you mean that I can just clone the repo in a location visible to my lulatex compiler?

[josephwright]

No, I mean that almost all users get luatex85 and indeed everything else TeX-related from their TeX system: you really shouldn't need to download it directly. What TeX system do you have (e.g. what does pdftex --version at the Command Line say)?

[adaldo]

If I pdftex --version I get

pdfTeX 3.1415926-2.5-1.40.14 (TeX Live 2013/Debian) kpathsea version 6.1.1 Copyright 2013 Peter Breitenlohner (eTeX)/Han The Thanh (pdfTeX). There is NO warranty.

OK, you have TL2013 so why do you need luatex85? This is needed to address issues that come from the LuaTeX version in TL16 (and is to aid the transition, not a permanent solution).

[adaldo]

I want to compile a beamer where I use a tikzlibrary called graphdrawing. To use this library I need to compile with lualatex, so I do lualatex my_awesome_beamer.tex. This returns me the following complaint

! Undefined control sequence. \checkfont #1^^@-\suppressfontnotfounderror =1\font \x = "#1" at 10pt \selectf... l.91 }

So I looked it up, and in some stackexchange thread (I can give you the link, if I manage to find it again), somebody said "try \RequirePackage{luatex85} ".

you should not believe everything you read on the internet:-) luatex85.sty will do nothing at all on old luatex.

But in general luatex is a fast changing engine which is being developed and so has many changes in commands each year. While it is possible to use tex or pdftex distributions from decades ago with few problems, if you are using luatex really you should update your tex system to texlive 2016, many luatex fragments that you find will not work with older luatex implementations.

What @davidcarlisle says :-) In this case, you are using code that's been updated for newer macro approaches. What you want is

\directlua{
  tex.enableprimitives("",tex.extraprimitives("luatex"))
}

at the start of your file.

However, note that LuaTeX is still very much in development. For reasons of realism, most package authors target only the current release, so the one in TeX Live 2016. You will face issues with older LuaTeX versions for this reason.

[adaldo]

Ok so here is our happy ending.

The \directlua fix works, but it clashes with \tikzlibrary{external}. My terminal tells me that I have to pdflatex -shell-escape my_awesome_beamer.tex. This does not work, but since I am using lualatex I get all smart and lualatex -shell-escape my_awesome_beamer.tex. This works fine and I can also see that after the first compile it gets all faster thanks to the exetrnalize.

Thank you all for your help!
