Minor modifications to make a better tutorial

[pablgonz]

Just consider the last commit, Modifications are for TeXLive only:

1. You can write the packages in only one line and also you can put comments.
2. Names were added to each of the tests in travis.yml.
3. Extended texlive-test for minted and biber.
4. Fixed main.tex file to compile without errors.
5. Added sudo apt-get install python-pygments to file travis.yml.
6. Added dist: xenian to the file travis.yml.
   I think that's all, in my tests compile everything without problems.
   Greetings

Thanks for the contribution!

I'm guessing you mean that texliveonfly won't detect these ones? How did you find this list? I don't have them here yet: https://tex.stackexchange.com/a/463842/98850 (under 'known problems') To create the package list you can use the following trick ```bash pdflatex -draftmode -interaction=batchmode "\RequirePackage{snapshot}\input{main}"  && perl -wnE 'say $1 if /(?:\*\{p.+?\}\s*)\{(.+?)\}(?:\s*\{.+?\})/' snapshot.dep ```

@pablgonz Ah I see you used the snapshot package, didn't know that one existed. But the snapshot.dep file shows LaTeX packages, not TeX Live packages, so it's not perfect (and you have to have all packages installed locally before it works) - though it definitely helps figuring out dependencies :)

[pablgonz]

I really don't think you can have a definitive solution to create the list of necessary packages, the collections in TeXLive install more than one package, and some packages have circular dependencies with others, but...something can be done in travis:).
With the following lines it is possible to see the list of packages installed in travis:

      after_script:
        - export PATH=/tmp/texlive/bin/x86_64-linux:$PATH
        - tlmgr list --only-installed | grep -oP 'i \K.+?(?=:)'
      name: "Run texlive-test"

Update my fork to your repository and I added some small changes, give me your opinion and if this correct I will do a pull request.
PS: Anyway, the best way to create the dependency list is to use "Trigger a custom build" and repeat until everything is installed correctly.

LaTeX tools will never be perfect, but we try to get as close as we can 😄

That will be useful, but I would prefer it if we do that the other way around, first you make a pull request and then I can approve the changes ;)

Good one, forgot about that. I think they didn't even have that custom build feature yet when I started using Travis. I just put a note for that in the Troubleshooting section.
