HTCondorWiki: Read The Docs

Read the Docs Overview

In 2019 we migrated the HTCondor Manual from our old LaTeX format into the Sphinx documentation generator using the reStructuredText format. We will also be hosting it on Read the Docs. The manual can be found here:

http://htcondor.readthedocs.io

Prerequisites

Install Python (https://www.python.org/downloads, or you system package manager). You must install Python 3+. We no longer support Python 2.
Install Sphinx and related support packages. The recommended way to install Sphinx is via `pip`, and we recommend using our pinned dependencies:
```
pip3 install --user -r docs/requirements.txt
```
On RHEL and CentOS we do not support installing Sphinx from yum or RPM. The available package is an old version which does not support all our extensions. For other Linux distributions, Windows and macOS, you can find instructions here:
- https://www.sphinx-doc.org/en/master/usage/installation.html
Install pandoc. On RHEL, for example:
```
sudo yum install pandoc
```
Windows and Mac installers can be found at https://github.com/jgm/pandoc/releases/
Install the HTCondor Python bindings. This could be via pip (make sure you get the right version, e.g. pip3 install htcondor==8.8.1), or by editing your PYTHONPATH environment variable to point at the packages in your HTCondor build. For example (replacing <htcondor-release-dir> with your local release directory path):
```
export PYTHONPATH=<htcondor-release-dir>/lib/python3:$PYTHONPATH
```
Note: on RTD, the docs are built using the pip-installed htcondor version read out of CMakeLists.txt, and the package versions in docs/requirements.txt.
If you're on Python <= 3.4 (editorial note: why?!), install the pathlib compatibility module:
```
pip3 install --user pathlib
```
[Optional] Install https://pypi.org/project/sphinx-autobuild/. This is useful if you're making lots of quick edits to the manual and expect to build it many times.
```
pip3 install --user sphinx-autobuild
```
See below for instructions on using sphinx-autobuild.

Building

Building and previewing the manual locally

The manual pages exist in our git repository under the /docs folder
Each top-level section of the manual has a corresponding subdirectory with the same name. For example, all the content for "Overview" is under /docs/overview, the content for "User's Manual" is under /docs/users-manual, and so on.
Each page of the manual has a corresponding file with the same name and a .rst extension. For example, the content for the "Overview > Exceptional Features" page is in /docs/overview/exceptional-features.rst
To make a local build of the manual, go to your /docs folder and run:
```
make html
```
To preview your build, open a web browser and go to the following URL: file:///<path-to-condor-src>/docs/_build/html/index.html
To clean your local build, go to your /docs folder and run:
```
make clean
```

Using sphinx-autobuild to build and preview

Instead of the instructions in the previous section, go to /docs and run

sphinx-autobuild . _build/html

You will see a log of the Sphinx build running, and eventually will be provided a link to a localhost webserver hosting the docs. Leave this program running: sphinx-autobuild will watch the docs source tree for changes and rebuild when it detects changes (you may still need to manually reload the page inside your web browser, but it will usually force a refresh by itself).

Different versions of the manual

Read the Docs allows us to host multiple versions of the manual. We'll have two separate versions: "latest" (equivalent to Development Release) and "stable" (equivalent to Stable Release).
To make edits to the latest version, make your changes on the master branch.
To make edits to the stable version, make your changes to the V8_8-branch (or the appropriate V8_8_X-branch if making your changes after code freeze)

Formatting Guidelines

See the Manual Formatting Guidelines page.

Publishing

Publishing the manual onto Read the Docs

Currently Mark or Josh has to login to Read the Docs to manually push any changes.

Different versions of the manual

To make changes to the devel/latest version of the manual, put all your changes in the master branch.
To make changes to the stable version of the manual, you need to add a tag called "stable" to the commit in V8_8-branch that contains the changes you want. To update the stable tag to a new commit, run the following:
```
git tag --delete stable
git push --delete origin tag stable
git tag stable
git push origin stable
```

Generating man pages

The files in /docs/man-pages will be the official source for our man pages going forward.
Sphinx can generate the man pages automatically. They will get output by default to the /docs/_build/man folder. From the /docs folder, run:
```
make man
```
