About Digodoc

This site was generated by digodoc. digodoc generates documentation for all the packages installed in a switch, indexed by opam packages, libraries, metas and modules. It is also able to transform package sources into HTML pages.


Frequently Asked Questions

1. Can I contribute to this site?

Yes, all contributions are welcome! The easiest way is to submit ideas and issues on the bug tracker of the digodoc project on Github. You can also directly modify the tools we use to improve them: beside digodoc, the odoc tool is also a good candidate for such work. Finally, if you are a student, OCamlPro usually takes interns during the summer, it's a great way to have a direct impact on the website from within the team that built it!

2. Why aren't some opam packages listed?

Currently, the documentation is generated by installing all the packages in a single opam switch for OCaml 4.10.0 on a Linux/Debian amd64 computer. So, only co-installable packages in this system are present.

3. Why isn't the version of package X the most recent one?

There are two main reasons: first, we regenerate the documentation from time to time, we don't follow closely the state of the opam repository; second, we try to maximize the number of packages in an opam switch, it sometimes requires to downgrade some package versions to increase the number of packages compatible with it.

4. Why aren't the modules of some packages documented?

The most frequent reason for a missing module documentation is the lack of installation of .cmt files. This usually happens for packages that use Makefiles for example (ocamlgraph). We are currently working on a way to solve this issue by patching the OCaml compiler. Note that we are interested in listing all such packages, so if you notice one, notify us!

5. Are there links between the documentation pages and the sources pages?

Not yet. However, we plan to work on adding such a feature in the next version. We will probably need to dive deeper into odoc for that.

6. Isn't the modules index slow to load?

Yes, it includes more than 17000 modules, and takes some time to load. We plan to create a dynamic version of the site soon, that will load the index incrementally.

7. Is it possible to do a text search in the documentation?

Not yet. However, we plan to add several search features when we will move to a dynamic website. For example, we will allow users to perform type-driven queries alongside standard full-text searches.
