Localization Maintenance

Localization for Keyman is maintained at https://translate.keyman.com

Downloading and updating files between Keyman and Crowdin happens on GitHub by way of the Crowdin git integration. The configuration file for all platforms is a YAML file named crowdin.yml. Currently, the git integration tracks the master branch.

A daily GitHub action to update the source files in Crowdin, which are organized in a top-level folder "master".

For most of our platforms, the only thing that needs to be done manually is to update crowdin.yml if new source files get added (and of course translating the strings on the Crowdin website).

Manual upload and download with Crowdin CLI

The following describes how alternatively the Crowdin CLI (v4) tool could be used to automate downloading and updating files between Keyman and Crowdin.

Note: On Windows, use crowdin.bat instead of crowdin for all the syntax below.

Add File

When adding new files to https://crowdin.com/project/keyman/settings#files also go to the file "Settings" and edit Resulting file after translations export:. This is where the translated files will appear in the Crowdin download (Keyman.zip) which also determines where the translated files get extracted locally into the Keyman project.

For example, android/KMEA/strings.xml string uses

/android/KMEA/app/src/main/res/values-%android_code%/strings.xml

Setup

Install Crowdin CLI v4 for your OS. Note, it has a prerequisite on Java 17 LTS.

Environment Variables

In Crowdin, create a personal access token and set it as an environment variable CROWDIN_PERSONAL_TOKEN.

Also copy the project id from API v2 and set it as an environment variable CROWDIN_PROJECT_ID.

Testing Crowdin CLI is Set Up Correctly

To check your CLI setup, in the repo root folder,

crowdin list project

You should see the CLI fetching project info and generating a list of files associated with the project.

Configuring Custom Language Codes

https://crowdin.com/project/keyman/settings#languages

Only the project owner (sil_ltops) can edit custom language codes (at the bottom of the "Target Languages" list). For some of these, the language mapping needs to be maintained in the "Language Mapping" button on the project settings menu (instead of the crowdin.yml) configuration file.

Language mappings have been set up for "Greek (Polytonic)" and "Shuwa (Latin)" so downloading with the Crowdin CLI would be:

crowdin download -b master -l el-polyton

crowdin download -b master -l shu-latn-n

Downloading from Crowdin

Since Crowdin is tracking the master branch, download translations will be zipped into a master folder.

To download the latest translations from Crowdin (all platforms), open a command line at the repo root folder and run:

crowdin download -b master

To download latest translations for the specific language:

crowdin download -b master -l {language_code}

Note: the Crowdin API doesn't handle custom languages so those will need to be manually synced. See https://support.crowdin.com/api/language-codes/

To display a list of latest translations from Crowdin:

crowdin download -b master --dryrun

Uploading to crowdin

To upload source files to Crowdin:

crowdin upload sources -b master

Note: this command uses the crowdin "branch" name (top-level folder), and doesn't necessarily correspond to the GitHub "branch" name.

Updating DisplayLanguages.java in Keyman Engine for Android

In Keyman for Android, the settings menu for changing display languages is maintained in android/KMEA/app/src/main/java/com/tavultesoft/kmea/DisplayLangugages.java

For the BCP-47 language tags to use in that file, don't include script names since the Android locales only handle language ID and region.

Updating Localization Targets in Keyman Engine / the Keyman App for iPhone and iPad

When a language receives its first localization for our iOS platform, a few settings must be tweaked within Xcode in order to enable it.

  1. For both the KeymanEngine and Keyman subprojects, go to the project page's info tab and inform Xcode of the appropriate language code.

Refer to this image for guidance.

Note that Xcode will usually fail to actually include the newly downloaded resources.

  1. So, to include those resources, search the workspace for each localized file and select them one at a time. When you do so, the right-hand side bar should a set of checkboxes for each localized language, with the new language unchecked.

This image should provide a helpful reference.

Clicking the checkbox will summon a dialog that will allow the existing file to be utilized.

Tip

Microsoft offers a website that allows to check how terms used in Windows are translated in different languages: https://www.microsoft.com/en-us/language/Search.
