This repository contains the documentation for openHAB.
The result is available at https://www.openhab.org/docs/ and https://www.openhab.org/addons/.
In this repo you can find and improve all general documentation contents.
In fact that is all you can see in the 2.5.x branch.
There are also other read-only branches, which hold external content like the add-ons and concepts documentation.
We will read about them later.
Correct, this is done in the original repository of the add-on. You may want to know how to find the right file in all of those repos? This is fairly easy: on most of the documentation pages on https://www.openhab.org/, you will find the following link at the bottom, which will point you directly to the file you want to improve.
When your improvement has been made and merged, we will get the updated article automatically through our build mechanism. This happens mostly once a day. Afterwards your change is included in the next build of the openHAB website.
The documentation is a community effort, so everyone is welcome to suggest changes, add new sections and fix bugs. This is done exactly the same way as for the code repositories, simply through pull requests against this repo. When editing a page through the "Edit this page on GitHub" link on the website, you will be given the opportunity to create a pull request directly from GitHub. Please read our contribution guidelines and try to follow them as best as you can before submitting a change for review - but don't worry if you don't understand all of them, we will help you to get it right.
We use them to bring together all relevant articles or to archive versioned content. Mostly those branches will get updated automatically through our continuous integration builds. You can read a bit more below about our external ressources and how we get them.
Those parts include all add-on documentation files, no matter if they are from the openhab-core repo, the
openhab1-addons repo, the openhab-addons repo or any special binding repo like habmin, zwave or the alexa skill.
We are keeping all those files at their original location, because it simply doesn't make sense to keep them here. Imagine you want to do an improvement of the zwave binding and have to update the readme file in a completely different place. That's twice the effort and also we would have to coordinate two Pull Requests. So we are saving time for everyone by keeping those files at their original location along with the code.
We have set up our build server to do the magic automatically. There are several triggers (mostly time based), which will then gather the external contents and move them to our final branch. You can find this migrated external content in the final branch under:
_addons_*concepts
You can even have a look at how this works in detail. The external content is updated by the following toolchain:
update-external-resources.sh→pom.xml→process_addons.groovy
Everything that gets updated in the master branch will be also merged over to the final branch automatically. Afterwards we will redeploy the website with the latest content from the final branch at regular intervals.
There are two triggers available currently.
The merge docs job is triggerd after something has been added to the documentation through this repository.
The gather external docs job is started with a succesful build of the openhab-distribution.
A succesful disribution build will include all of the latest changes that have been made to external sources like addons.
So when a distribution build is succesful, we will trigger the gathering of all external sources.
When one of these jobs is finished, we will then notify our website hosting service to start a new website build. This is recognized due to new commits in the final branch of this repository. The new build will include all the latest changes in the code repository and in all external repositories.
Just as openHAB is released in versions, the documentation website provides fixed versions of the documentation articles, e.g., https://www.openhab.org/v2.2/installation/linux.html
Please see this issue for all details regarding the tagging and branching approach. In short, the following has to be considered:
- Versions like "2.1.0" are marked by git tags.
- Based on tags branches like "2.1-patch" are created, to include later discovered changes (like fixed links).
When a version is tagged (or updated), a static version of the website has to be generated and copied into the correct sub-folder, this is currently a manual operation described succinctly here: openhab/website#72
