Distro: Linux Mint 20
Flatpak Version: 1.6.3
The TeXLive extension to the freedesktop Sdk, runtime/org.freedesktop.Sdk.Extension.texlive, is very large: the 19.08 branch has an installed size of 3.9 GB. I assume, based on its large size, that it contains a fully-working copy of texlive. My questions concern how I can actually make use of this copy of texlive.
There are some apps on flathub, such as TeXStudio, that already include the extension as a dependency. But there are at least two use cases where I would want to use the extension outside of apps like TeXStudio.
1)In a text editor flatpak app that doesn’t already call the extension as a dependency:
Suppose I am using a text editor to write a LaTeX file. As an example, I’ll use Kate (org.kde.kate on Flathub). Kate has a “build” plugin which can automate the process of building a project. However, the Kate flatpak doesn’t call the TeXLive extension as a dependency, and the KDE Sdk doesn’t include a LaTeX implementation. Thus, if I am editing a tex file in the Kate flatpak, I can’t use the build plugin.
One workaround is to give Kate access to host libraries, install texlive as a Deb package, and then use flatpak-spawn --host. The problems with this approach is that it means I am still reliant on my distro to ship an up-to-date version of texlive, and I have to break the sandbox around Kate to use it. This seems contrary to the spirit of Flatpak. If I were to switch to a distro that doesn’t ship a reasonably updated LaTeX implementation, then this workaround wouldn’t work.
Is there another way? Is there some option to give an already-compiled flatpak app (like Kate) access to the TexLive extension without having to rebuild the app myself?
2)Directly from the terminal outside of a flatpak app:
When I have the texlive deb package installed, I can use it directly from the terminal. Running “pdflatex foo.tex” compiles foo.tex into foo.pdf, and running “biber foobar” produces bibliography files from foobar.bib.
But suppose I were to use a distro that doesn’t ship texlive in its native package manager, or which ships a severely outdated version compared to what is hosted on Flathub. Is there a way to use the texlive SDK extension to call pdflatex and or other commands directly from the host terminal? Using
$ flatpak run org.freedesktop.Sdk.Extension.texlive/x86_64/19.08 pdflatex foo.tex
produces the error “bwrap: execvp /bin/sh: No such file or directory,” and similar commands I’ve tried have the same result.
