# Contributing to Mailspring
|
|
|
|
Thanks for checking out Mailspring! We'd love for you to contribute. Whether
|
|
you're a first-time open source contributor or an experienced developer, there
|
|
are ways you can help make Mailspring great!
|
|
|
|
## Contributing Code
|
|
|
|
One of the best ways is to grab a
|
|
[bug report](https://community.getmailspring.com/c/bugs/10),
|
|
[sync issue](https://community.getmailspring.com/c/sync/22),
|
|
or [feature suggestion](https://community.getmailspring.com/c/features/12)
|
|
that has been marked `accepted` and dig in. You can especially look for issues
|
|
marked as `help-wanted` or `low-hanging-fruit`.
|
|
|
|
Please be wary of working on issues *not* marked as `accepted`. Just because
|
|
someone has created an issue doesn't mean we'll accept a pull request for it.
|
|
See [Where to Contribute](#where-to-contribute) below for more information.
|
|
|
|
You can also help implement *any* feature by creating a **plugin** for it!
|
|
If you need inspiration, you can dig through the list of
|
|
[feature suggestions](https://community.getmailspring.com/c/features/12),
|
|
especially looking for anything marked `for-plugin`.
|
|
|
|
### Pull requests
|
|
|
|
The first time you submit a pull request, a bot will ask you to sign a
|
|
standard, bare-bones Contributor License Agreement. The CLA states that you
|
|
waive any patent or copyright claims you might have to the code you're
|
|
contributing. (For example, you can't submit a PR and then sue Mailspring
|
|
for using your code.)
|
|
|
|
## Triaging Issues
|
|
|
|
Another way to help is to [answer questions](https://community.getmailspring.com/c/help/7),
|
|
or to triage [bug reports](https://community.getmailspring.com/c/bugs/10) and
|
|
[sync issues](https://community.getmailspring.com/c/sync/22). If you're good at
|
|
testing and addressing issues, we'd love your help!
|
|
|
|
## Filing Issues
|
|
|
|
If you have a bug to report or a feature to suggest, you may do so on our
|
|
[Discourse](https://community.getmailspring.com/). Please carefully follow all
|
|
instructions in the template for the given type of issue you're reporting.
|
|
|
|
We also ask that you search for existing issues, *including closed ones!*
|
|
We're in the process of migrating. If someone has already reported a bug or
|
|
requested the feature you have in mind, **vote for it** at the top.
|
|
Higher voted issues are more likely to be addressed.
|
|
|
|
For bugs, please verify that you're running the latest version of Mailspring.
|
|
If you file an issue without providing detail, we may close it without comment.
|
|
|
|
**Under no circumstances should you report an issue via GitHub. The GitHub
|
|
Issues feature is exclusively for Mailspring contributors to track tasks
|
|
which have been diagnosed, accepted, and scheduled on the roadmap.**
|
|
|
|
# Build and Run From Source
|
|
|
|
If you want to understand how Mailspring works or want to debug an issue,
|
|
you'll want to get the source, build it, and run it locally.
|
|
|
|
## Installing Prerequisites
|
|
|
|
You'll need git and a recent version of Node.JS (currently v16.X is recommended
|
|
with npm v8.1.2+). [nvm](https://github.com/creationix/nvm) is also highly
|
|
recommended. Based on your platform, you'll also need:
|
|
|
|
**Windows:**
|
|
|
|
- `npm install --global --production windows-build-tools`
|
|
|
|
**OS X:**
|
|
|
|
- Python
|
|
- Xcode and the Command Line Tools (Xcode -> Preferences -> Downloads), which
|
|
will install `gcc` and the related toolchain containing `make`.
|
|
|
|
**Linux:**
|
|
|
|
- Python v2.7
|
|
- make
|
|
- A proper C/C++11 compiler tool chain, for example GCC
|
|
- Library dependencies:
|
|
- On Debian-based Linux: `sudo apt-get install libx11-dev libxkbfile-dev execstack libgconf-2-4 libsecret-1-dev`
|
|
- On Red Hat-based Linux: `sudo yum install libX11-devel.x86_64 libxkbfile-devel.x86_64 libsecret-1-dev libsecret-devel`.
|
|
|
|
After you have these tools installed, run the following commands to check out
|
|
Mailspring,install dependencies, and launch the app:
|
|
|
|
```
|
|
git clone https://github.com/foundry376/mailspring
|
|
cd mailspring
|
|
npm install
|
|
npm start
|
|
```
|
|
|
|
## Development Workflow
|
|
|
|
### App Data
|
|
|
|
When you're running Mailspring with `npm start`, it runs with the `--dev` flag
|
|
and user data is located in a `Mailspring-dev` folder alongside the regular
|
|
settings folder:
|
|
|
|
- Mac: `~/Library/Application Support/Mailspring-dev`
|
|
- Windows: `C:\Users\<you>\AppData\Roaming\Mailspring-dev`
|
|
- Linux: `~/.config/Mailspring-dev/`
|
|
|
|
### Developer Tools
|
|
|
|
From Mailspring, you can open the Developer Tools from the
|
|
menu: `Menu > Developer > Toggle Developer Tools`. Here are a few tips for
|
|
getting started:
|
|
|
|
- Errors and warnings will show in the console.
|
|
|
|
- On the console, `$m` is a shorthand for `mailspring-exports`, and allows you
|
|
to access global `Stores` and `Model` classes.
|
|
|
|
- You don't need to stop and restart the development version of Mailspring
|
|
after each change. You can just reload the window via `CTRL+R` (Windows/Linux)
|
|
or `CMD+R` (macOS).
|
|
|
|
### Linting
|
|
|
|
We use `prettier` and `eslint` for linting our sources. You can run both of
|
|
these by running `npm run lint` on the command line. Always do this before
|
|
submitting a pull request to ensure the CI servers accept your code.
|
|
|
|
### Documentation
|
|
|
|
Back in 2015 and 2016, the Nylas Mail team made a huge effort to document
|
|
the codebase. The docs are still
|
|
[available on GitHub pages](https://foundry376.github.io/Mailspring/), and are
|
|
still largely relevant to Mailspring development.
|
|
|
|
### Testing Localization
|
|
|
|
You can run the app in different localizations by passing a langauge code to
|
|
Electron via `--lang=de`. To use this in conjunction `npm start`, you'll need
|
|
to use the `--` argument forwarding syntax: `npm start -- --lang=de`.

# Where to Contribute
|
|
|
|
Check out our [Discourse](https://community.getmailspring.com/) for all
|
|
potential areas for contributions. Note that just because a topic exists does
|
|
not mean we will accept a contribution to the core mail client for it. There
|
|
are several reasons we may not accepts a pull requests, like:
|
|
|
|
- **Maintainability** - We're _extremely_ wary of adding options and preferences
|
|
for niche behaviors. Email is a wild west, and we can't afford to support
|
|
every possible configuration. Our general rule is that the code complexity
|
|
of adding a preference isn't worth it unless the user base is fairly evenly
|
|
divided about the desired behavior.
|
|
[We don't want to end up with this!](https://cloud.githubusercontent.com/assets/1037212/14989123/2a74e810-110b-11e6-8b5d-6f343bca712f.png)
|
|
|
|
- **User experience** - We want to deliver a lightweight and smooth mail
|
|
client, so UX and performance matter a lot. If you'd like to change or
|
|
extend the UI, consider doing it in a plugin or theme.
|
|
|
|
- **Architectural** - The team and/or feature owner needs to agree with any
|
|
architectural impact a change may make. Things like new extension APIs must
|
|
be discussed with and agreed upon by the feature owner. To improve the
|
|
chances to get a pull request merged you should select an issue that is
|
|
labelled with the help-wanted or bug labels.
|
|
|
|
In short, if the issue you want to work on is not labelled with `accepted`, you
|
|
can start a conversation on the Discourse topic about whether an external
|
|
contribution will be considered.
|
|
|
|
# Code of Conduct
|
|
|
|
In order to keep the conversation clear and transparent, please limit
|
|
discussion to English and keep things on topic with the issue. Be considerate
|
|
to others and try to be courteous and professional at all times.
|
|
|
|
Please note that this project is released with a Contributor Code of Conduct.
|
|
By participating in this project you agree to abide by its terms.
