## Contributing
|
||
|
||
Okular uses the merge request workflow.
|
||
Merge requests are required to run pre-commit CI jobs; please don’t push to the master branch directly.
|
||
See https://community.kde.org/Infrastructure/GitLab for an introduction.
|
||
|
||
### Build instructions
|
||
|
||
Okular can be built like many other applications developed by KDE.
|
||
See https://community.kde.org/Get_Involved/development for an introduction.
|
||
|
||
If your build environment is set up correctly, you can also build Okular using CMake:
|
||
|
||
```bash
|
||
git clone https://invent.kde.org/graphics/okular.git
|
||
cd okular
|
||
mkdir build
|
||
cd build
|
||
cmake -DCMAKE_INSTALL_PREFIX=/path/to/your/install/dir ..
|
||
make
|
||
make install
|
||
```
|
||
|
||
Okular also builds tests in the build tree. To run them, you have to run `make install` first.
|
||
|
||
If you install Okular in a different path than your system install directory it is possible that you need to run
|
||
|
||
```bash
|
||
source prefix.sh
|
||
```
|
||
|
||
so that the correct Okular instance and libraries are picked up.
|
||
Afterwards one can run `okular` inside the shell instance.
|
||
The source command is also required to run the tests manually.
|
||
|
||
As stated above, Okular has various build targets.
|
||
Two of them are executables.
|
||
You can choose which executable to build by passing a flag to CMake:
|
||
|
||
```bash
|
||
cmake -DCMAKE_INSTALL_PREFIX=/path/to/your/install/dir -DOKULAR_UI=desktop ..
|
||
```
|
||
Available options are `desktop`, `mobile`, and `both`.
|
||
|
||
### clang-format
|
||
|
||
The Okular project uses clang-format to enforce source code formatting.
|
||
See [README.clang_format](https://invent.kde.org/graphics/okular/-/blob/master/README.clang-format) for more information.
