Contributing to the wiki
So, you’ve decided you want to edit the wiki. Awesome! This page will show you how to get started. Please follow the instructions that are most appropriate for you.
Cloning the wiki
Using repo
If you already have a LineageOS source tree checked out, then this step is done for you. The wiki’s git repository is present under $LINEAGE_SRC/lineage/wiki.
Using git
If you don’t have a LineageOS source tree on your device, then you can clone the wiki from GitHub to any directory you like. In this example, we’ll use ~/lineage_wiki.
Install Git
On Windows
Install Git for Windows.
On macOS
Install Git using the Git installer.
On Linux
You can install Git by running:
sudo apt-get install git
More specific instructions for different distributions can be found here.
Configure Git
Run:
git config --global user.name "Your Name"
git config --global user.email "youremail@example.com"
git clone command with your GitHub username.git clone https://github.com/LineageOS/lineage_wiki ~/lineage_wiki
cd ~/lineage_wiki
curl -Lo .git/hooks/commit-msg https://review.lineageos.org/tools/hooks/commit-msg
chmod +x .git/hooks/commit-msg
Making and previewing changes
You can now make changes in this folder using your favorite text editor. If you ever need to reset your folder to a known-good state, erasing your changes, just run:
git reset --hard HEAD
Preview using GitHub
This is probably the easiest method, but requires you to have forked the wiki repository, and have cloned from that.
Commit and preview your changes
Run:
git add .
git commit
An editor will pop up. In the first line, type a short (below 80 character) description of your changes, then put a blank line, and, if you want, a more detailed description of your changes. For example:
Add the contributing page
The contributing page will show people how they can edit our wiki, which
is important, since it wouldn't be much of a wiki without editors.
Save the file and exit the editor. Now upload your changes to GitHub:
git push origin
Preview your changes - you can see your fork of the wiki at http://yourusername.github.io/lineage_wiki.
Fixing mistakes
So, you’ve made your change, and you can look at the wiki on GitHub pages. But something’s wrong! You made a typo - or accidentally deleted something. Have no fear! You can fix it.
First, fix the mistake(s) you made. Then, to push them to GitHub:
git add .
git commit --amend
Your commit message should show up in an editor. You can edit it, or just quit the editor. Finally, run:
git push --force origin
Preview locally using docker
Install docker
Add docker keyring and install the package:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt update
sudo apt install docker-ce
Add your user account to the docker group in order to use docker commands without prefixing sudo:
sudo gpasswd -a $USER docker
newgrp docker
Then log out of your user account and log back in or reboot to make the group membership changes take effect.
Build the docker image
This builds the docker image, which should only need to be done once:
cd $LINEAGE_SRC/lineage/wiki #Or to wherever you cloned the repository
docker build -t lineageos/wiki .
Edit the wiki
Each time that you want to edit the wiki, you will need to start a local web server running Jekyll:
cd $LINEAGE_SRC/lineage/wiki
docker run -p 4000:4000 -v $(pwd):/src -it lineageos/wiki
At this point you should be able to view the local Jekyll server.
Preview locally using rvm and jekyll
Install rvm
rvm is a great tool to isolate different usages of ruby from each other. During this setup, you will install ruby and a set of ruby modules (gems) which will be isolated from any other ruby use on the machine (now and in the future).
If you don’t have rvm already installed, go ahead and install it:
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
curl -sSL https://get.rvm.io | bash -s stable
Configure ruby for editing the wiki
These steps will configure and install the latest version of ruby MRI via rvm. All gems (modules) are stored in the namespace lineage_wiki and the environment will be configured to allow remote access to GitHub. Once configured, ruby will be installed and the required gems downloaded:
cd $LINEAGE_SRC/lineage/wiki
echo ruby > .ruby-version
echo lineage_wiki > .ruby-gemset
rvm install ruby
gem install bundler rails
bundle install
Edit the wiki
Each time that you want to edit the wiki, you will need to start a local web server running Jekyll:
source ~/.rvm/scripts/rvm
cd $LINEAGE_SRC/lineage/wiki
bundle exec jekyll serve --incremental
At this point you should be able to view the local Jekyll server.
.md file of the page that you are viewing in the browser. An easy way to do that is: touch pages/*/<devicename>*--host <fully-qualified hostname> to the Jekyll command line to allow remote connections to the server.Uploading your changes
LineageOS uses Gerrit to review proposed changes. Before you begin, you’ll need to create an account, and configure an SSH key (you will need to use the ed25519 type of key).
After you’ve done this, you can push your commits to Gerrit:
git remote add gerrit ssh://<gerritusername>@review.lineageos.org:29418/LineageOS/lineage_wiki
git push gerrit HEAD:refs/for/master
You can add the “Wiki Editors” group as reviewers (click on the little person to the right of “reviewers”). Someone will either: comment on the patch, asking for clarification or pointing out typos. You can reply to them, or fix any issues they point out, and then re-run:
git push gerrit HEAD:refs/for/master
Eventually, when your change looks perfect, someone will approve it, and submit it to the wiki. Awesome!
