I believe when contributing to Firefox OS and Gaia, just like with most open source projects, a lot of attention should be given to reducing the barrier for entry for new contributors. It is even more vital for Gaia since it is an extremely fast moving project and the number of things to keep track of is overwhelming. In an attempt to make it easier to start contributing to Firefox OS Accessibility I compiled the following list of resources, that I will try keeping up to date. It should be helpful for a successful entry into the project:
Firstly, links to high level documentation:
One of my coworkers (James Burke) proposed the following workflow that you might find useful (link to source):
yzenas an example)
git clone --recursive email@example.com:yzen/gaia.git gaia-yzen cd gaia-yzen git remote add upstream firstname.lastname@example.org:mozilla-b2g/gaia.git
# this updates your local master to match mozilla-b2g's latest master # you should always do this to give better odds your change will work # with the latest master state for when the pull request is merged git pull upstream master # this updates your fork on github's master to match git push origin master # Create bug-specific branch based on current state of master git checkout -b bug-123
Now you will be in the
bug-123 branch locally, and its contents will look the same as the
master branch. The idea with bug-specific branches is that you keep your master branch pristine and only matching what is in the official mozilla-b2g branch. No other local changes. This can be useful for comparisons or rebasing.
Do the changes in relation to the bug you are working on.
Commit the change to the branch and then push the branch to your fork. For the commit message, you can just copy in the title of the bug:
git commit -am "Bug 123 - this is the summary of changes." git push origin bug-123
Now you can go to https://github.com/yzen/gaia and do the pull request.
In the course of the review, if you need to do other commits to the branch for review feedback, once it is all reviewed, you can flatten all the commits into one commit, then force push the change to your branch. I normally use
rebase -i for this. So, in the
gaia-yzen directory, while you are in the bug-123, you can run:
git rebase -i upstream/master
At this point, git gives you a way to edit all the commits. I normally 'pick' the first one, then choose 's' for squash for the rest, so the rest of the commits are squashed to the first picked commit.
Once that is done and git is happy, you can the force push the new state of the branch back to GitHub:
git push -f origin bug-123

All apps are located in apps/ directory. Each up is located within its own directory. So for example if you are working on a Calendar app you would be making your changes in the apps/calendar directory.
The way we want to make sure that the improvements that we work on actually help Firefox OS accessibility and do not regress we have a policy of adding gaia-ui python Marionette tests for all new accessible functionality. You can find tests in the tests/python/gaia-ui-tests/gaiatest/tests/accessibility/ directory.

Localization is very relevant to accessibility especially because one of the tasks that we perform when making something accessible is ensuring that all elements in the applications are labeled for the user of assistive technologies. Please see Localization best practices for guidelines on how to add new text to applications.
Using a device or navigating a web application is different with the screen reader. Screen reader introduces a concept of virtual cursor (or focus) that represents screen reader's current position inside the app or web page. For mode information and example videos please see: Screen Reader
Here are some of the basic resources to help you get to know what mobile accessibility (and accessibility) is:
