I am trying to call the program groff from inside a gedit flatpak (external tools plugin).
The flatpak can access the groff binary, but groff looks for files at /usr/share/groff, while in flatpak, this path is mapped to /var/run/host/usr/share/groff.
What is the proper way of accessing a binary like this? Or rather the datadir of a binary like this?
Probably the best way is to set environment variables
export GROFF_TMAC_PATH=/var/run/host/usr/share/groff/site.tmac
export GROFF_FONT_PATH=/var/run/host/usr/share/groff/site-font
