# Contributing to GNSS-SDR
|
|
|
|
:+1::tada: Thanks for taking the time to contribute! :tada::+1:
|
|
|
|
Third-party contributions are essential for keeping GNSS-SDR
|
|
continuously improving. We simply cannot access the huge number of
|
|
platforms and myriad configurations for running GNSS-SDR. We want to
|
|
keep it as easy as possible to contribute changes that get things
|
|
working in your environment. There are a few guidelines that we need
|
|
contributors to follow so that we can have a chance of keeping on top of
|
|
things.
|
|
|
|
The following is a set of guidelines for contributing to GNSS-SDR, which
|
|
is hosted in the [GNSS-SDR Organization](https://github.com/gnss-sdr) on
|
|
GitHub. These are just guidelines, not rules. Use your best judgment,
|
|
and feel free to propose changes to this document in a [pull
|
|
request](#how-to-submit-a-pull-request).
|
|
|
|
## Code of Conduct
|
|
|
|
This project adheres to the Contributor Covenant [code of
|
|
conduct](CODE_OF_CONDUCT.md). By participating, you are expected to
|
|
uphold this code. Please report unacceptable behavior.
|
|
|
|
## Reporting an issue
|
|
|
|
Have you found a bug in the code which is not in the [list of known
|
|
bugs](https://github.com/gnss-sdr/gnss-sdr/issues)? Do you have a
|
|
suggestion for improvement? Then by all means please [submit a new
|
|
issue](https://github.com/gnss-sdr/gnss-sdr/issues/new), and do not
|
|
hesitate to comment on existing [open
|
|
issues](https://github.com/gnss-sdr/gnss-sdr/issues).
|
|
|
|
When filling a new issue, please remember to:
|
|
|
|
* **Use a clear and descriptive title** for the issue to identify the
|
|
problem.
|
|
|
|
* **Describe the exact steps which reproduce the problem** in as many
|
|
details as possible. For example, start by describing your computing
|
|
platform (Operating System and version, how did you installed GNSS-SDR
|
|
and its dependencies, what file or front-end are you using as a signal
|
|
source, etc.). You can also include the configuration file you are
|
|
using, or a dump of the terminal output you are getting. The more
|
|
information you provide, the more chances to get useful answers.
|
|
|
|
* **Please be patient**. This organization is run on a volunteer basis,
|
|
so it can take some time to the Developer Team to reach your issue.
|
|
They will do their best to fix it as soon as possible.
|
|
|
|
* If you opened an issue that is now solved, it is a good practice to
|
|
**close it**.
|
|
|
|
The list of [open issues](https://github.com/gnss-sdr/gnss-sdr/issues)
|
|
can be a good starting point and a source of ideas if you are looking to
|
|
contribute to the source code.

## Contributing to the source code
|
|
|
|
### Preliminaries
|
|
|
|
1. If you still have not done so, [create your personal account on
|
|
GitHub](https://github.com/join).
|
|
|
|
2. [Fork GNSS-SDR from
|
|
GitHub](https://github.com/gnss-sdr/gnss-sdr/fork). This will copy the
|
|
whole gnss-sdr repository to your personal account.
|
|
|
|
3. Then, go to your favorite working folder in your computer and
|
|
clone your forked repository by typing (replacing ```YOUR_USERNAME``` by
|
|
the actual username of your GitHub account):
|
|
|
|
$ git clone https://github.com/YOUR_USERNAME/gnss-sdr
|
|
|
|
4. Your forked repository https://github.com/YOUR_USERNAME/gnss-sdr
|
|
will receive the default name of `origin`. You can also add the original
|
|
gnss-sdr repository, which is usually referred to as `upstream`:
|
|
|
|
$ cd gnss-sdr
|
|
$ git remote add upstream https://github.com/gnss-sdr/gnss-sdr.git
|
|
|
|
To verify the new upstream repository you have specified for your fork,
|
|
type `git remote -v`. You should see the URL for your fork as `origin`,
|
|
and the URL for the original repository as `upstream`:
|
|
|
|
```
|
|
$ git remote -v
|
|
origin https://github.com/YOUR_USERNAME/gnss-sdr.git (fetch)
|
|
origin https://github.com/YOUR_USERNAME/gnss-sdr.git (push)
|
|
upstream https://github.com/gnss-sdr/gnss-sdr.git (fetch)
|
|
upstream https://github.com/gnss-sdr/gnss-sdr.git (push)
|
|
```
|
|
|
|
### Start working on your contribution
|
|
|
|
Checkout the `next` branch of the git repository in order to get
|
|
synchronized with the latest development code:
|
|
|
|
```
|
|
$ git checkout next
|
|
$ git pull upstream next
|
|
```
|
|
|
|
When start working in a new improvement, please **always** branch off
|
|
from `next`. Open a new branch and start working on it:
|
|
|
|
```
|
|
$ git checkout -b my_feature
|
|
```
|
|
|
|
Now you can do changes, add files, do commits (please take a look at
|
|
[how to write good commit
|
|
messages](https://chris.beams.io/posts/git-commit/)!) and push them to
|
|
your repository:
|
|
|
|
```
|
|
$ git push origin my_feature
|
|
```
|
|
|
|
If there have been new pushes to the `next` branch of the `upstream`
|
|
repository since the last time you pulled from it, you might want to put
|
|
your commits on top of them (this is mandatory for pull requests):
|
|
|
|
```
|
|
$ git pull --rebase upstream next
|
|
```
|
|
|
|
### How to submit a pull request
|
|
|
|
Before submitting your code, please be sure to [apply clang-format](https://gnss-sdr.org/coding-style/#use-tools-for-automated-code-formatting).
|
|
|
|
When the contribution is ready, you can [submit a pull
|
|
request](https://github.com/gnss-sdr/gnss-sdr/compare/). Head to your
|
|
GitHub repository, switch to your `my_feature` branch, and click the
|
|
_**Pull Request**_ button, which will do all the work for you. Code
|
|
comparison must be always to the `next` branch.
|
|
|
|
Once a pull request is sent, the Developer Team can review the set of
|
|
changes, discuss potential modifications, and even push follow-up
|
|
commits if necessary.
|
|
|
|
Some things that will increase the chance that your pull request is
|
|
accepted:
|
|
|
|
* Avoid platform-dependent code. If your code require external
|
|
dependencies, they must be available as packages in [Debian OldStable](https://wiki.debian.org/DebianOldStable).
|
|
* Write tests.
|
|
* Follow our [coding style guide](https://gnss-sdr.org/coding-style/).
|
|
* Write a descriptive and detailed summary. Please consider that
|
|
reviewing pull requests is hard, so include as much information as
|
|
possible to make your pull request's intent clear.
|
|
|
