Good! I'll try to add support today for Gentoo.

I know some Kernel devs that even package the Kernel they built for their own consumption with rpm or dpkg - even taking a lot more time to do that ;) The thing if using the OS-packaging is that the packaging tool can be used to check everything installed at the system, with makes a lot easier when installing a package or upgrading. For example, when I upgraded my system to Fedora 26, as python changed from version 3.5 to version 3.6, I had to destroy the virtual envs and re-create them again. If I had used, instead, the OS-packaging, that would be transparent. The same happens if I wanted to upgrade Sphinx packages to a newer version. > For python, instead of : > > printf "\t$virtualenv sphinx_1.4\n"; > printf "\tpip install 'docutils==0.12'\n"; > printf "\tpip install 'Sphinx==1.4.9'\n"; > printf "\tpip install sphinx_rtd_theme\n"; > > add Documentation/sphinx/requirements.txt: > > <snip: requirements.txt> --- > docutils==0.12 > Sphinx==1.4.9 > sphinx_rtd_theme > <snap> --------------------- > > And the print ... > > printf "\t$virtualenv sphinx_1.4\n"; > printf "\tpip install -r Documentation/sphinx/requirements.txt\n"; Yeah, I can do that. > > For TexLive: > > ATM I have no idea how to set up a *requierements* file and > install everything without sudo.

I see two problems with tlmgr: - tlmgr is not installed by default (at least on Fedora); - adding packages with other package managers makes admin process a way more complex for upgrades and security fixes. That's why I opted to use only kpsewhich. > But for this I have to do more investigations / sorry that > I can't spend more time on this task right now. > > > - should it have an optional argument that will make the > > script to run the needed commands; > > No. We can do this later upstream. > > > - should it be integrated at the Documentation/Makefile? > > No. > > > - what's the best name/location for such script? > > I like to see the script under Documentation/sphinx If the idea is to run the scripts standalone, scripts/ is a better place. > > > I guess it could also use kpsewhich to check if the needed > > texlive packages are installed.

It works fine for Fedora and OpenSuse. No need for Debian or Arch Linux, as texlive is lot less granular there.

I'm pretty sure that buildbots will use OS-packaging: a build bot farm could easily become an admin nightmare if the packages are not managed by a single package management system.
