Development Guide

Installing the development environment

Please refer to the installation guide.

Testing the federation

To test the federation, you'll need to setup another database (see "Setup the database"), also owned by the "plume" user, but with a different name. Then, you'll need to run the migrations for this database too.

diesel migration run --database-url postgres://plume:plume@localhost/my_other_plume_db

To run this other instance, you'll need to give two environment variables:

• ROCKET_PORT, the port on which your app will run
• DB_NAME, the name of the database you just created

ROCKET_PORT=3033 DB_NAME=my_other_plume_db cargo run

If you don't want to setup HTTPS locally, you can also disable it by running your instance with USE_HTTPS=0 set.

USE_HTTPS=0 cargo run

Making a Pull Request

To create an upstream fork of the repository in GitHub, click "Fork" in the top right button on the main page of the Plume repository. Now, in the command line, set another remote for the repository by running the following command, replacing myname with the name under which you forked the repo. You can use another name besides upstream if you prefer. Using SSH is recommended.

git remote add upstream git@github.com/myname/Plume.git
# Alt # git remote add upstream https://github.com/myname/Plume.git

Now, make any changes to the code you want. After committing your changes, push to the upstream fork. Once your changes are made, visit the GitHub page for your fork and select "New pull request". Add descriptive text, any issue numbers using hashtags to reference the issue number, screenshots of your changes if relevant, a description of how you tested your changes, and any other information that will help the project maintainers be able to quickly accept your pull requests.

The project maintainers may suggest further changes to improve the pull request even more. After implementing this locally, you can push to your upstream fork again and the changes will immediately show up in the pull request after pushing. Once all the suggested changes are made, the pull request may be accepted. Thanks for contributing.

When working with Tera templates

When working with the interface, or any message that will be displayed to the final user, keep in mind that Plume is an internationalized software. To make sure that the parts of the interface you are changing are translatable, you should:

• Use the _ and _n filters instead of directly writing strings in your HTML markup
• Add the strings to translate to the po/plume.pot file

Here is an example: let's say we want to add two strings, a simple one and one that may deal with plurals. The first step is to add them to whatever template we want to display them in:

<p>{{ "Hello, world!" | _ }}</p>

<p>{{ "You have {{ count }} new notifications" | _n(singular="You have one new notification", count=n_notifications) }}</p>

As you can see, the _ doesn't need any special argument to work, but _n requires singular (the singular form, in English) and count (the number of items, to determine which form to use) to be present. Note that any parameters given to these filters can be used as regular Tera variables inside of the translated strings, like we are doing with the count variable in the second string above.

The second step is to add them to POT file. To add a simple message, just do:

msgid "Hello, world" # The string you used with your filter
msgstr "" # Always empty

For plural forms, the syntax is a bit different:

msgid "You have one new notification" # The singular form
msgid_plural "You have {{ count }} new notifications" # The plural one
msgstr[0] ""
msgstr[1] ""

And that's it! Once these new messages will have been translated, they will correctly be displayed in the requested locale!

Code Style

For Rust, use the standard style. rustfmt can help you keeping your code clean.

For CSS, the only rule is to use One True Brace Style.

For JavaScript, we use the JavaScript Standard Style.

For HTML/Tera templates, we use HTML5 syntax.
