Created attachment 451450 [details, diff] Adding 'TEXINPUTS' into the set 'colon_separated' The tool 'env_update' collects variable definitions from files in /etc/env.d and builds /etc/profile.env. Certain variables, when defined in multiple files in /etc/env.d, are concatenated with a colon (':') as separator in between. Prime example is the variable PATH. Which variables are recognized as 'can be concatenated with a colon as separator' is defined in variable colon_separated around line 111 in file pym/portage/util/env_update.py in the sources for Portage. In this feature request, I would like to request to add variable TEXINPUTS as used TeX systems. Various TeX tools use this variable to locate files (e.g. packages, fonts, images) to be used during a compilation which may not be placed in the default locations (e.g. CWD, /usr/share/texmf*, ...). An example where setting TEXINPUTS during a package installation is necessary is package for SDAPS (http://sdaps.org/). SDAPS used to automate the generation and evaluation of paper-based questionnaires and as such allows the generation of questionnaires both with LaTeX and LibreOffice. For LaTeX, a number of files are installed in /usr/share/sdaps/tex and cannot be found by LaTeX tools like pdflatex or kpsewhich unless TEXINPUTS is set to include /usr/share/sdaps/tex. The package SDAPS will install a file 95sdaps into /etc/env.d which contains the single line TEXINPUTS="/usr/share/sdaps/tex" Eventually, /etc/profile.env shall contain a line like this: TEXINPUTS="/some/other/path:/usr/share/sdaps/tex:/yet/another/path"

Ok, I'll try that. Is there a reason why variable 'colon_separated' still lists some very specific variable names such as ADA_INCLUDE_PATH or KDEDIRS (which is KDE4-specific), apart from historic reasons and that none has changed that?
The existing values are just for backward compatibility.
