This repository contains the Opal Gallery application which showcases all modules. The module examples can be used as a starting point for new applications.

You can find documentation on how to use Opal in other applications in the main repo. If you want to use applications using Opal, you should not have to do anything.

Development

1. Clone this repository e.g. to src/opal/opal
2. Run fetch-modules.sh to fetch the latest module sources, clone required module repositories as requested
3. Open the project file harbour-opal-gallery.pro in the Sailfish OS IDE
4. Build an RPM package and install it on the target device

Adding new modules

Please refer to the main repo for documentation on how to setup new modules.

Module metadata and examples live in the respective repositories. After the new module is properly prepared, register it in fetch-modules.sh. Run the script to include the new module in Opal Gallery.

Screenshots

You can find screenshots here.

Permissions

Opal Gallery requires the following Sailjail permissions:

• Internet: for showcasing optional online features in modules
• MediaIndexing: for showcasing the Opal.MediaPlayer module
• Videos: for showcasing the Opal.MediaPlayer module

All network access is optional and requires explicit user interaction.

Help and support

You are welcome to leave a comment in the forum if you have any questions or ideas.

Translations

It would be wonderful if the app could be translated in as many languages as possible!

Translations are managed using Weblate. Please prefer this over pull requests (which are still welcome, of course). If you just found a minor problem, you can also open an issue.

Manually updating translations

Please prefer using Weblate over this.

You can follow these steps to manually add or update a translation:

1. If it did not exist before, create a new catalog for your language by copying the base file translations/harbour-opal-gallery.ts. Then add the new translation to harbour-opal-gallery.pro.
2. Add yourself to the list of translators in TRANSLATORS.json, in the section extra.
3. (optional) Translate the app's name in harbour-opal-gallery.desktop if there is a (short) native term for it in your language.

See the Qt documentation for details on how to translate date formats to your local format.

Building and contributing

Bug reports, and contributions for translations, bug fixes, or new features are always welcome!

1. Clone the repository by running git clone --recursive https://codeberg.org/opal-sfos/harbour-opal-gallery
2. Open harbour-opal-gallery.pro in QtCreator for Sailfish (SailfishOS SDK)
3. To run on emulator, select the i486 target and press the run button
4. To build for the device, select the aarch64 or armv7hl target and click “deploy all”; the RPM packages will be in the RPMS folder

If you contribute, please do not forget to add yourself to the list of contributors in qml/pages/AboutOpalPage.qml!

I am always happy if you buy me a cup of coffee through Liberapay if you want to support my work.

Of course it would be much appreciated as well if you support this project by contributing to translations or code! See above how you can contribute 🎕.

Anti-AI policy

Please be transparent, respect the Free Software community, and adhere to the licenses. This is a welcoming place for human creativity and diversity, but LLM/“AI”-generated slop is going against these values.

Apart from all the ethical, moral, legal, environmental, societal, social, political, technical, and overall human, reasons against LLMs/“AI”, I also simply don't have any spare time to review generated contributions.

See also this list for more reasons against supporting “AI”.
