commit b89749ae1df489ab7de2cdc1c74a4b10f098f9f1
Author: Jean-Marc Lasgouttes <[email protected]>
Date: Tue Jun 25 15:46:14 2019 +0200
Let TeXFiles.py handle symbolic links.
Nix (https://nixos.org) is a Unix package manager, which can be used to
install LaTeX on macOS. A peculiarity of Nix is that all packages are
installed into separate directories and the actual directory tree is
then constructed via symlinks.
This interacts badly with the way LyX currently detects files in the
TeX setup, because TeXFiles.py does not follow symlinks. Therefore,
almost nothing is found when using LyX together with Nix’ LaTeX.
Patch from Michael Roitzsch.
