Getting the book to build on readthedocs

Yesterday I had a Skype chat with Charles from China. It turned out that he had been reading the docs on! The last successful build there was a year and 4 months ago! I vaguely remember that last time it failed because they have some quota and the book was too big. Now I tried again and saw that they have (of course!) evolved since then and that I had a .readthedocs.yml, but maybe they require it to be named .readthedocs.yaml. I renamed it and updated the requirements setting to use our central file. Nice. That was one of the disturbing things, that you needed an extra requirements.txt file in the docs subdirectory. But it still fails (build 13215043:

So the pip install python_ldap doesn’t work. Yes, python_ldap has some build prerequisites, but readthedocs doesn’t seem to have an option where I can tell it to install them. I read their docs page but couldn’t find any such option. So I abandoned once more.

Publish the Lino Book on GitLab

Before deleting the project on RTD, I should publish the docs somewhere else. On GitHub pages? Last time I tried this, it was a bit twisted because GitHub doesn’t care much about Sphinx. And anyway I want to move to GitLab.

Current situation:

$ go book
$ git remote -v show
origin (fetch)
origin (push)

Let’s try to change this (as instructed here):

$ go book
$ git push --set-upstream master
Counting objects: 23898, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (7741/7741), done.
Writing objects: 100% (23898/23898), 34.35 MiB | 622.00 KiB/s, done.
Total 23898 (delta 17150), reused 22397 (delta 15930)
remote: Resolving deltas: 100% (17150/17150), done.
remote: The private project lino-framework/book was successfully created.
remote: To configure the remote, run:
remote:   git remote add origin
remote: To view the project, visit:
 * [new branch]        master -> master
Branch 'master' set up to track remote branch 'master' from ''.

Before I can add a remote, I must remove the existing remote:

$ git remote rm origin
$ git remote add origin

Yes, seems that it worked:

$ git remote -v show
origin (fetch)
origin (push)

Next step is to add a .gitlab-ci.yml file. I just copied that of the Lino Mentori project, which is already on GitLab.

Evening session

Yes, I moved the Community Guide from GitHub to GitLab. This was easier because there is no test suite, just a Sphinx build.

And then Atelier, which I also released to PyPI because Developer Guide has intersphinx dependencies to it.

Next time I will continue to move repositories from GH to GL. It will take some time until all links in all docs are updated.
