OpenBoard upgrade, WIP

This is an attempt to integrate changes / improvements into OpenBoard that have been sitting around for a long time due to low dev activity. Might end up on F-Droid...

This is mostly a development version. On updates there may be changes that reset some settings. Consider all releases as beta quality at best.

Features

  • Allow loading Glide typing library
    • not included in the app, as there is no compatible open source library
    • can be extracted from GApps packages (swypelibs), or downloaded here
  • Multilingual typing
  • Load external dictionaries
    • get them here, or in the experimental section (quality may vary)
    • additional dictionaries for emojis or scientific symbols can be used to provide suggestions ("emoji search")
    • note that for Korean layouts, suggestions only work using this dictionary, the tools in the dictionary repository are not able to create working dictionaries
  • Adjust keyboard themes (style and colors)
    • can follow the system's day/night setting on Android 10+ (and on some versions of Android 9)
  • Split keyboard (if the screen is large enough)
  • Number row
  • Number pad
  • Show all available extra characters on long pressing a key

Hidden functionality

Features that may go unnoticed

  • Long pressing the clipboard key (the optional one in suggestion strip) pastes system clipboard contents
  • Long pressing keys in the suggestion strip toolbar pins them to the suggestion strip
  • Long-press comma to access clipboard view, emoji view, one-handed mode, settings, or switch language
    • emoji view and language switch will disappear if you have the corresponding key enabled
    • for some layouts it's not the comma-key, but the key at the same position (e.g. it's q for Dvorak layout)
  • Press the incognito icon to get the toolbar (probably only hidden if you use force incognito mode)
  • Sliding key input: swipe from shift to another key to type a single uppercase key
    • also works for the ?123 key to type a single symbol from the symbols keyboard, and for related keys
  • Long-press a suggestion in suggestion strip to show more suggestions, and a delete button to remove this suggestion
  • Swipe up from a suggestion to open more suggestions, and release on the suggestion to select it
  • You can add dictionaries by opening them in a file explorer
    • only works with content-uris and not with file-uris, meaning that it may not work with some file explorers
  • Debug APK only
    • Long-press a suggestion to show the source dictionary
    • Debug settings in advanced preferences, though not very useful except for dumping dictionaries into the log
    • When the app crashes, you will be asked whether you want crash logs when you open the settings
  • For users doing manual backups with root access: starting at Android 7, the shared preferences file is not in the default location, because the app is using device protected storage. This is necessary so the settings can be read before the device is unlocked, e.g. at boot.
    • file is located in /data/user_de/0/<package_id>/shared_prefs/, though this may depend on the device and Android version

Important differences and changes to OpenBoard

The rough plan/todo before "full" release

  • Add/change pre-defined themes
  • Internal clean up (xml files, unused resources and classes)
    • even after a lot of work here, the current state look rather messy, with many useless and duplicate entries
  • work through _todo_s in code
  • Make suggestion removal functionality more discoverable
  • Better detection when to separate words and when not (e.g. detection of email addresses and URLs)
  • Fix some bugs
    • especially the spell checker issue Helium314#55
    • "partial" multi-character codepoint deletion with delete gesture (e.g. for emojis), Helium314#22

Once above is done, we can think about properly releasing the app. First just in this repository, and later on F-Droid. This would include renaming the app and the package, changing the icon and using a localization tool (most likely weblate).

Further plan

  • more customizable theming
  • improved / less bad suggestions in some cases
  • add emojis to user history, to be used for next word suggestions
  • sliding key input for numpad and emojis (like ?123 and shift sliding input)
  • updated suggestion strip, maybe add tools or make the suggestions scroll

Issue reporting

Whether you encountered a bug, or want to see a new feature in OpenBoard, you can contribute to the project by opening a new issue here. Your help is always welcomed !

Before opening a new issue, be sure to check the following :

  • Does the issue already exist ? Make sure a similar issue has not been reported by browsing existing issues.
  • Is the issue still relevant ? Make sure your issue is not already fixed in the latest version of OpenBoard.
  • Did you use the issue template ? It is important to make life of our kind contributors easier by avoiding issues that miss key informations to their resolution.

Please avoid opening issues to ask for a release date, for PR reviews/merges, for more activity on the project, or worth for more contributors. If you have any interrogations on these topics, read this comment from issue #619.

Translation

You can help in translating OpenBoard in your language through our Weblate project.

Translation status

Dictionary creation

To create or update a dictionary for your language, you can use this tool. You will need a wordlist, as described here. The output .dict file must be put in res/raw, and its wordlist in dictionaries.

For your dictionary to be merged into OpenBoard, you must provide the wordlist you used, as well as its license if any.

Code contribution

Getting started

OpenBoard project is based on Gradle and Android Gradle Plugin. To get started, you'll just need to install Android Studio, and import project 'from Version Control / Git / Github' by providing this git repository URL (or git SSH URL).

Once everything got setted up correctly, you're ready to go !

Guidelines

OpenBoard is a complex application, when contributing, you must take a step back and make sure your contribution :

  • Uses already in-place mechanism and take advantage of them. In other terms, does not reinvent the wheel or uses shortcuts that could alter the consistency of the existing code.
  • Has the lowest footprint possible. OpenBoard code has been written by android experts (AOSP/Google engineers). It has been tested and runned on millions of devices. Thus, existing code will always be safer than new code. The less we alter existing code, the more OpenBoard will stay stable. Especially in the input logic scope.
  • Does not bring any non-free code or proprietary binary blobs. This also applies to code/binaries with unknown licenses. Make sure you do not introduce any closed-source library from Google.
  • Complies with the user privacy principle OpenBoard follows.

In addition to previous elements, OpenBoard must stick to F-Droid inclusion guidelines.

Current TODO list

In no particular order, here is the non-exhaustive list of known wanted features :

  • Updated emoji support
  • MaterialYou (M3) support
  • One-handed mode feature
  • Android autofill support
  • Clipboard history feature
  • Text navigation/selection panel
  • Multi-locale typing
  • Emoji search
  • Emoji variant saving
  • Glide typing

Tooling

Edit keyboards content

Keyboards content is often a complex concatenation of data from global to specific locales. For example, additional keys of a given key, also known as 'more keys' in code, are determined by concatenating infos from : common additional keys for a layout (eg. numbers), global locale (eg. common symbols) and specific locale (eg. accents or specific letters).

To edit these infos, you'll need to generate the KeyboardTextsTable.java file. To do so :

  1. Make your modifications in tools/make-keyboard-text/src/main/resources/values-YOUR LOCALE.
  2. Generate the new version of KeyboardTextsTable.java by running Gradle task 'makeText' :
    ./gradlew tools:make-keyboard-text:makeText

Update emojis

See make-emoji-keys tool README.
