[NTG-context] Lua related change in LuaMetaTeX?
Hi, starting with LuaMetaTeX 2.07.01, a C library I load from Lua started to segfault and valgrind indicates that it accesses invalid memory in multiple places in the middle of Lua internal functions?! The whole thing looks almost like the Lua versions in LuaMetaTeX and in the library are incompatible, but both seem to use 5.4.0. So I asked myself if there might be changes not reflected by the version number. tl;dr: Has the embedded Lua interpreter changed in some non ABI-compatible way in LuaMetaTeX 2.07.01? (Especially on Linux, x86-64. I didn't test other platforms yet) Best regards, Marcel ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Re: [NTG-context] Installing VSCode extension?

Running that command produces the errors: Installing extensions... Extension 'context' not found. Make sure you use the full extension ID, including the publisher, e.g.: ms-dotnettools.csharp Failed Installing Extensions: context: For what it's worth, I'm running VSCode 1.46.0.

Here i just run this (seems to work with latest update): data/context/vscode-context.cmd (I only occasionally check vscode and will look into it again when there is easy suffix dependent runner support. Of course I do generate the syntax files.)

[NTG-context] Height of parentheses in a matrix with lmtx
Hi Hans,
With the upgraded version of lmtx, the parentheses of the matrix are no
longer adjusted to the content.
Thank you.
