## Issues
|
|
|
|
[Issues](https://gitlab.com/mx-moment/moment/-/issues) on GitLab should be used to
|
|
ask questions, report problems, request new features,
|
|
or discuss potential changes before creating pull requests.
|
|
We also pay attention to [Mirage issues on GitHub](https://github.com/mirukana/mirage/issues).
|
|
|
|
Before opening new issues, please search for any already open or closed
|
|
issue related to your problem, in order to prevent duplicates.
|
|
|
|
You can also join us in the
|
|
[#moment-client:matrix.org](https://matrix.to/#/%23moment-client:matrix.org)
|
|
room for questions and discussions.
|
|
|
|
|
|
## Pull Requests
|
|
|
|
For changes outside of simple bug/typo/formatting fixes, it is strongly
|
|
recommended to first discuss your ideas in a related issue or in
|
|
[#moment-client:matrix.org](https://matrix.to/#/%23moment-client:matrix.org).
|
|
|
|
New changes are merged to the
|
|
[`dev` branch](https://gitlab.com/mx-moment/moment/-/tree/dev) first.
|
|
Once a new version of the application is released,
|
|
the current `dev` is merged into the main `main` branch.
|
|
|
|
By sending your changes, you agree to license them under the LGPL 3.0 or later.
|
|
|
|
### Procedure
|
|
|
|
Start by forking the main repository from GitLab, then
|
|
clone your fork and switch to a new branch based on `dev`, in which
|
|
you will make your changes:
|
|
|
|
```sh
|
|
git clone --recursive https://gitlab.com/yourUsername/moment
|
|
cd moment
|
|
git remote add upstream https://gitlab.com/mx-moment/moment
|
|
git fetch upstream
|
|
git checkout upstream/dev
|
|
git branch example-branch-name
|
|
git checkout example-branch-name
|
|
```
|
|
|
|
Test and commit your changes according to the
|
|
[commit guidelines](#commit-guidelines), and `git push` to your fork's repo.
|
|
You will then be able to make a pull request by going
|
|
to the [main repo](https://gitlab.com/mx-moment/moment).
|
|
|
|
Once your pull request is merged, you can update `dev`, and delete your
|
|
GitLab and local branch:
|
|
|
|
```sh
|
|
git fetch upstream
|
|
git checkout upstream/dev
|
|
|
|
git push -d origin example-branch-name
|
|
git branch -d example-branch-name
|
|
```
|
|
|
|
Make sure `dev` is up-to-date before creating new branches based on it.
|
|
|
|
|
|
## Commit Guidelines
|
|
|
|
Commit messages should be made in this form:
|
|
|
|
```
|
|
Title, a short summary of the changes
|
|
|
|
The body, a more detailed summary needed depending on the changes.
|
|
Explain the goal of the code, how to reproduce the bug it solves
|
|
(if this is a bug fix), any special reasoning behind the
|
|
implementation or side-effects.
|
|
```
|
|
|
|
- Write informative titles, e.g.
|
|
`TextField: fix copying selected text by Ctrl+C` instead of
|
|
`fix field bug`
|
|
(assuming `TextField` was the name of the component affected by the bug)
|
|
|
|
- Write the title in imperative form and without a period at the end,
|
|
e.g. `Fix thing` instead of `Fixed thing` or `Fixes thing.`
|
|
|
|
- The title must not exceed 50 characters
|
|
|
|
- A blank line is required between the first line summary and detailed
|
|
body, if there is one
|
|
|
|
- Lines of the body must not exceed 72 characters
|
|
|
|
- Split independent changes into separate commits,
|
|
don't combine fixes for different problems or add multiple systems forming a
|
|
complex feature all at once
|
|
|
|
- Every commit should be able to build and run the application without
|
|
obvious crashes or tracebacks
|
|
|
|
- Check for linter errors before committing by running `make test` in the
|
|
repository's root. The test tools can be installed with
|
|
`pip3 install --user -Ur requirements-dev.txt`.
|
|
|
|
- For changes that aren't yet merged in a branch of the main repo,
|
|
prefer amending or editing previous commits via git interactive rebase,
|
|
rather than adding new "fix this" commits.
|
|
This helps keeping the history clean.
|
|
|
|
|
|
## Coding Conventions
|
|
|
|
### General
|
|
|
|
- Use four space indentations, no tabs
|
|
|
|
- Use double quotes for strings, unless single quotes would avoid having to
|
|
escape double quotes in the text
|
|
|
|
- Keep lines under 80 columns, the only exception for this is long URL links
|
|
that can't be broken in multiple parts
|
|
|
|
- Keep lines free from any trailing whitespace
|
|
|
|
- Function definitions, calls, list/dict/etc not fitting in
|
|
one line follow this format (notice the trailing comma on the last element):
|
|
|
|
```python3
|
|
long_function_call(
|
|
long_argument_1, long_argument_1, long_argument_3, long_argument_4,
|
|
)
|
|
|
|
very_long_list_def = [
|
|
"Lorem ipsum dolor sit amet, consectetuer adipiscing elit",
|
|
"Aenean massa. Cum sociis natoque penatibus",
|
|
"Mus donec quam felis, ultricies nec, pellentesque",
|
|
]
|
|
```
|
|
|
|
- When creating new files, don't forget the copyright and license
|
|
header you see in other files of the same language.
|
|
|
|
### Python
|
|
|
|
- All functions, class attributes or top-level variables should have type hints
|
|
|
|
- Separate all top-level classes and functions by two blank lines.
|
|
For classes with many long methods, separate those methodes by two blank
|
|
lines too.
|
|
|
|
- Readability is important. Vertically-align consecutive lines of assignments,
|
|
function definition arguments, dictionaries and inline comments:
|
|
|
|
```python3
|
|
# Bad:
|
|
|
|
num: int = 1 # A comment
|
|
args: List[str] = ["a", "b"] # Another comment
|
|
|
|
def func(
|
|
self,
|
|
example_argument: int = 300, # Comment
|
|
other: str = "Sample text", # Other comment
|
|
some_floats: Tuple[float, float, float] = (4.2, 1.1, 9.8),
|
|
) -> None:
|
|
pass
|
|
|
|
# Good:
|
|
|
|
num: int = 1 # A comment
|
|
args: List[str] = ["a", "b"] # Another comment
|
|
|
|
def func(
|
|
self,
|
|
example_arg: int = 300, # Comment
|
|
other: str = "Sample text", # Other comment
|
|
some_floats: Tuple[float, float] = (4.2, 9.8),
|
|
) -> None:
|
|
pass
|
|
```
|
|
|
|
If this is annoying, consider getting a plugin for your editor to automate it
|
|
(e.g. [EasyAlign](https://github.com/junegunn/vim-easy-align) for vim).
|
|
|
|
- Use f-strings as long as the readability isn't impacted.
|
|
For more complex string formatting, use the shorter `%` syntax when features
|
|
special to `str.format()` aren't needed.
|
|
|
|
- Otherwise, follow the
|
|
[PEP-8 standard](https://www.python.org/dev/peps/pep-0008/)
|
|
|
|
### QML
|
|
|
|
- Don't add trailing semicolons to lines
|
|
|
|
- If an object has more than one property, always keep each property on their
|
|
own line:
|
|
|
|
```qml
|
|
Rectangle { x: 10; width: 100; height: width; color: "black" } // Bad!
|
|
|
|
Rectangle { // Good
|
|
x: 10
|
|
width: 100
|
|
height: width
|
|
color: "black"
|
|
}
|
|
```
|
|
|
|
- When creating new files, the `id` for the root component should always
|
|
be `root`
|
|
|
|
- When writing new code, refer to parent object properties explicitely, e.g.
|
|
`parent.prop_name` or `someId.prop_name` instead of just `<prop_name>`
|
|
|
|
- Don't use [States](https://doc.qt.io/qt-5/qml-qtquick-state.html),
|
|
the Rectangle in the description's example could simply be written like this:
|
|
|
|
```qml
|
|
Rectangle {
|
|
width: 100
|
|
height: 100
|
|
color: mouseArea.containsPress ? "red" : "black"
|
|
|
|
MouseArea {
|
|
id: mouseArea
|
|
anchors.fill: parent
|
|
}
|
|
}
|
|
```
|
|
|
|
- Otherwise, follow the
|
|
[QML Coding Conventions](https://doc.qt.io/qt-5/qml-codingconventions.html)
|
|
|
|
### C++
|
|
|
|
- Add C++ only if it can't easily be done in QML or Python;
|
|
or if doing it in Python requires adding a dependency while a
|
|
similar feature is already provided by Qt, feature that just needs to be
|
|
exposed with some wrapper code
|
|
([example](https://github.com/mirukana/mirage/blob/v0.6.4/src/utils.h#L31)).
|
|
|
|
- Be explicit, always use `this->` to refer to methods and class attributes
|
|
|
|
- Don't split modules between `.h` and `.cpp` files, this creates unnecessary
|
|
code repetition and has no benefits when most methods will
|
|
contain very few lines and the module is only included once before
|
|
starting the GUI.
|
|
|
|
|
|
## Resources
|
|
|
|
Resources include background images, icons or sounds.
|
|
New resources must have a permissive license that does not require attribution.
|
|
Built-in icons must be in the SVG format. The majority of icons used in the
|
|
application come from [iconmonstr](https://iconmonstr.com).
|
|
|
|
When possible without any noticable quality loss, reduce the size of
|
|
resources and strip any metadata by using tools such as:
|
|
|
|
- `svgcleaner --allow-bigger-file --indent 4 <file> <output>` for SVG images
|
|
- `pngquant --force --speed=1 --strip <file> <output>` for PNG images
|
|
- `jpegoptim --quality 80 --strip-all <file>` for JPEG images
|
|
|
|
|
|
## Packaging
|
|
|
|
If a new package for a distribution or any other easy way
|
|
of installing the application exists, [pull request](#pull-requests) for
|
|
adding instructions to the [INSTALL.md](INSTALL.md) are welcome.
|
|
|
|
Some suggestions when creating packages:
|
|
|
|
- Among the dependencies from the `submodules` directory, `hsluv-c` is the
|
|
only one that is still needed for building.
|
|
The other folders are kept to allow building past versions of the
|
|
application, and should be ignored.
