lmtx vs mkiv

lmtx vs mkiv

[Hans Hagen]

Hi,

One problem of mixed usage of mkiv (with luatex) and lmtx (with 
luametatex) is that in the later we use a different (initial) context 
runner. Basically all platforms are now handled the same (in mkiv there 
was a stub and no texlua, in unix something shebang with texlua because 
of argument passing limitations).

However, the main context script can be told to use a specific engine:

context --luatex foo.tex

so in principle one can use both lmtx and mkiv with the same binary 
tree, given that luametatex and luatex are both present and that 
luametatex is in charge.

For that reason the latest lmtx installer now (for the time being) also 
includes the luatex binary (plus mkiv files needed) so that one can 
install lmtx and run both engines. Instead of the --luatex switch one 
can also force the engine in the usual way with "% engine=luatex" at the 
top line of the source file (but no pdftex and xetex in this installer).

FWIW, the lmtx installation ships with the latest experimental luatex 
binary but normally that should not have consequences, but it does 
permits testing occasional updates.

Hans

I updated LMTX on MacOSX 10.13 today.

The luatex binary in not executable, thus when I run

axel$ context --luatex --version
mtx-context     | redirect luametatex -> luatex: luatex --luaonly "/usr/local/texlive/LMTX/tex/texmf-osx-64/bin/mtxrun.lua" --script mtx-context --luatex --version --redirected
mtx-context     | ConTeXt Process Management 1.02
mtx-context     |
mtx-context     | main context file: /Volumes/Macintosh HD/usr/local/texlive/2019/texmf-dist/tex/context/base/mkiv/context.mkiv
mtx-context     | current version: 2019.03.21 21:39

it picks up the TeX-Live version.

after I 

axel$ chmod 744 luatex 

I get the correct version:

axel$ context --luatex --version
mtx-context     | redirect luametatex -> luatex: luatex --luaonly "/usr/local/texlive/LMTX/tex/texmf-osx-64/bin/mtxrun.lua" --script mtx-context --luatex --version --redirected
mtx-context     | ConTeXt Process Management 1.03
mtx-context     |
mtx-context     | main context file: /Volumes/Macintosh HD/usr/local/texlive/LMTX/tex/texmf-context/tex/context/base/mkiv/context.mkiv
mtx-context     | current version: 2020.04.03 10:31
mtx-context     | main context file: /Volumes/Macintosh HD/usr/local/texlive/LMTX/tex/texmf-context/tex/context/base/mkiv/context.mkxl
mtx-context     | current version: 2020.04.03 10:31

Greetings
Axel

The binary for Windows 64bit is missing (or in a different folder) on 
the server because I get the following message as content for luatex.exe

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL /build/luatex/x86_64-w64-mingw32/luatex.exe was not 
found on this server.</p>
</body></html>
