+A guide to creating layouts
+===========================

-It’s long overdue to write a comprehensive guide how to add a keyboard layout from start. But unfortunately, I don’t have much time left ATM. A lot of information can be found in [this ](https://forums.puri.sm/t/using-non-latin-language-on-librem-5/7103/5) thread.
+This guide is based on the original Kareema's [forum post](https://forums.puri.sm/t/translations-and-virtual-touch-keyboards-tracking-localization/7669/48).

-So at least I will try to start writing a short how-to here and edit this post as I find the time. Hope this helps a bit - comments and corrections welcome.

-**Get one of the existing keyboard layouts**
+So at least I will try to start writing a short how-to here and edit this post as I find the time. Hope this helps a bit - comments and corrections [welcome](https://source.puri.sm/Librem5/squeekboard/-/merge_requests/)

-* You can get one of the keyboards from the squeekboard git repository : [https://source.puri.sm/Librem5/squeekboard ](https://source.puri.sm/Librem5/squeekboard)
-* The keyboard layouts are located in the subdirectory `data/keyboard/` in the `.yaml` files
+## Creating a new layout
+
+Creating a layout is easy. You don't need to recompile things, just edit and test. It's easiest to start with an existing layout.
+
+### Get one of the existing keyboard layouts
+
+* You can get one of the keyboards from the squeekboard git repository : [https://source.puri.sm/Librem5/squeekboard](https://source.puri.sm/Librem5/squeekboard)
+* The keyboard layouts are located in the subdirectory [`data/keyboards/`](https://source.puri.sm/Librem5/squeekboard/-/tree/master/data/keyboards) in the `.yaml` files
 * Take a look and try to understand them :slight_smile:

-**Fork your own copy of squeekboard**
+
+### Creating the keyboard layout
+
+* To be written: For the time being, take a look at [Using non-latin language on Librem 5](https://forums.puri.sm/t/using-non-latin-language-on-librem-5/7103/5)
+* The correct name of the .yaml file can be found with the command 
+
+```
+gsettings get org.gnome.desktop.input-sources sources
+```
+
+The output should be something like this: `[('xkb', 'us'), ('xkb', 'de')]`
+So for example “de.yaml” would be the correct name for the German keyboard layout.
+
+If the name of your layout is not translated correctly in the list, you can fix it by adding it and recompiling Squeekboard.
+
+### Testing the layout
+
+Copy your yaml file to `~/.local/share/squeekboard/keyboards/` for testing purposes. From there it should get picked up by squeekboard automatically.
+
+You can also use the `test_layout` tool from the -devel package to check it for errors:
+
+```
+# squeekboard_test_layout ./mylayout.yaml
+Test result: OK
+```
+
+## Contributing your changes
+
+If you want to share your layout with the world, the best way is to submit it to the Squeekboard project. The workflow is similar to any other Gitlab-based project.
+
+Above all, your layout should be working, be tested, not break anything, and make sense.
+
+### Fork your own copy of squeekboard

 * Best way would be to start with a fork of the squeekboard repository: Create a user account at https://source.puri.sm/, go the the squeekboard git repository, press “Fork” in the web interface. You can find further instructions [here](https://docs.gitlab.com/ee/user/project/repository/forking_workflow.html#creating-a-fork).
 * Clone your fork locally with `git clone` and use the uri of your forked repo there

-**Workflow to edit your keyboard and get it merged**
+### Edit your keyboard and get it merged

-* A generic guide how the workflow to contribute works, can be found at https://developer.puri.sm/Librem5/Contact/Contributing.html
+* It may be useful to check out the [generic guide how the workflow to contribute works](https://developer.puri.sm/Librem5/Contact/Contributing.html)
 * Create a branch: Name it “keyboard-layout-mylanguage” or whatever
 * Checkout your branch, edit your keyboard layout and commit your changes
+* Your layout **must** be correctly named, and in `data/keyboards/`.
+* Your layout **must** pass the `test_layout` tool with zero problems.
+* Your translation **must** be correctly named, and in `data/langs/`.
+* Your layout or translation **must** be added to automatic tests. **Don’t forget to add it** to `src/resources.rs` and the layout to `tests/meson.build` (that’s for me, because I always forget it).
+
+### Get it merged
+
+It's always recommended to **compile and run** squeekboard before submitting your changes. This serves as a test that all is working. See instructions in the [compiling section](#compiling-and-running-squeekboard).
+
 * Push the local changes (to the branch of your fork of squeekboard)
 * Create a merge request for the branch to get your changes merged to the official squeekboard git repository

-**Compile squeekboard**
+If your changes pass automated tests (CI), then the merge request will be reviewed by the maintainers, and you might be asked to change a thing or two.

-* Follow the instructions found in “Building” section of the squeekboard’s README: Running squeekboard: [https://source.puri.sm/Librem5/squeekboard/blob/master/README.md#building ](https://source.puri.sm/Librem5/squeekboard/blob/master/README.md#building)
+## Compiling and running Squeekboard

-**Running squeekboard**
+If you want your change to become part of official Squeekboard, or if you want to add a translation of your layout name, you will have to recompile Squeekboard and test your changes there.

-* Follow these instructions to run squeekboard: [https://source.puri.sm/Librem5/squeekboard/blob/master/README.md#running ](https://source.puri.sm/Librem5/squeekboard/blob/master/README.md#running)
+### Compile squeekboard
+
+* Follow the instructions found in “Building” section of the squeekboard’s README: Running squeekboard: [https://source.puri.sm/Librem5/squeekboard/blob/master/README.md#building](https://source.puri.sm/Librem5/squeekboard/blob/master/README.md#building)

 * Additionally take a look at the contribution document for [testing info](HACKING.md#testing)
-* You can either test it locally on your Linux system or use the [QEMU Librem 5 image ](https://developer.puri.sm/Librem5/Development_Environment/Boards/emulators.html)
+* You can either test it locally on your Linux system or use the [QEMU Librem 5 image](https://developer.puri.sm/Librem5/Development_Environment/Boards/emulators.html)
 * To test squeekboard locally, you need phoc. Either compile that from the sources as well or use the CI repository ci.puri.sm for Debian based systems:
  `deb [arch=amd64] http://ci.puri.sm/ scratch librem5`

 Squeekboard can be installed from there as a Debian package, too (that’s what I often do). But beware - there be dragons! You could bork your system with these packages and you should probably disable this repository again after installing what you need - these packages are not meant for production systems (or so I heard :wink: )
-
-**Creating the keyboard layout**
-
-* To be written: For the time being, take a look at [Using non-latin language on Librem 5 ](https://forums.puri.sm/t/using-non-latin-language-on-librem-5/7103/5)
-* The correct name of the .yaml file can be found with the command `gsettings get org.gnome.desktop.input-sources sources`
-
-The output should be something like this: `[('xkb', 'us'), ('xkb', 'de')]`
-So f.ex. “de.yaml” would be the correct name for the German keyboard layout.
-* The translations for the keyboard layout names in the different languages can be found at `data/langs/`
-* Don’t forget to add your newly created layout or translation to `src/resources.rs` and the layout to `tests/meson.build` (that’s for me, because I always forget it)
-
-**Testing the layout**
-
-* Copy your yaml file to `~/.local/share/squeekboard/keyboards/` for testing purposes. From there it should get picked up by squeekboard
-* To test the translations in `data/langs/` , you have to compile squeekboard

Dorota Czaplejewicz	153f9c39e5	lint: Check for missing braces The `eek/layersurface.c` file should be excluded because it's an imported, "foreign" source, but clang-tidy doesn't seem to have an annotation for that. An alternative would have been to exclude it in Meson and do the check there, but that requires clang-tidy, raising the barrier to contribute of Squeekboard even more (it already requires libfeedback, which isn't packaged widely).	2020-10-20 11:34:17 +00:00

Arnaud Ferraris	9dd67ad2bc	server-context-service: optimize height calculation Even though proper size management is being worked on, this patch proposes a simple and easily revertable solution to device-dependent sizing issues. First, it provides different calculations based on the display orientation. In landscape mode, this allows us to have a sensible keyboard size while leaving enough screen estate for apps to be able to display useful information. Then, it gets rid of the weird calculation for display widths between 360 and 540px. While having some continuity is a pleasant idea, in the real world in doesn't work, as shown by port attempts to other devices: a 480x800 display (scale 1) would show an unusable 190px-high keyboard (about half the size of the Librem 5 on-screen keyboard on a device I own). Finally, this commit makes sure we never use a hardcoded size. Tested on the PinePhone, PineTab and Librem 5. Note: Current behavior is preserved on the L5 in portrait mode, but keyboard is a bit smaller in landscape mode; this is deliberate, as it was previously using too much space (causing some apps, such as chatty, to be unusable).	2020-10-09 16:30:59 +02:00
Arnaud Ferraris	9f4cb3c791	eek-gtk-keyboard: use virtual resolution to check arrangement kind Using the actual monitor width in pixels can lead to unsatisfying results, depending on the display orientation and physical size: on a 10" tablet with a 1280x800 resolution (scale 1), portrait orientation will be using the narrow layout. If the keyboard is sized in an optimal way (i.e. so the layout fills the whole area, with no blanks on the sides) this would result in an unnecessarily huge keyboard being displayed, therefore wasting screen estate. Using the virtual display size gives a hint about the physical size of the device, and can be used to select wide layouts even in portrait mode, while still preserving current behavior on HiDPI devices. This has been tested on PineTab, PinePhone and Librem 5.	2020-10-09 16:26:10 +02:00

Benjamin Schaaf	74479ff226	Expand key press detection to the edges of the view's bounding box If you have a keyboard layout like the following: A B C D E F G H I J K The E and G keys here should be pressed when clicking in the empty space next to them. This is achieved by not checking the bounding boxes of each key and instead just using the button and row offset to extend buttons/rows to the edges of the view. Caching for the size and position of rows is introduced to simplify implementation and possibly improve performance. Fixes #191	2020-09-26 01:37:23 +10:00
