airflow: Skill for Claude Code

Airflow Translations

Determining the Task

Translation work falls into one of two categories depending on whether the target locale already exists. Check if a directory for the locale exists under airflow-core/src/airflow/ui/public/i18n/locales/<locale>/. If it does, skip ahead to Updating an Existing Translation. If not, start with Adding a Translation below.

Adding a Translation

When adding a translation, some configuration files need to be updated before translation work can begin.

Setting up the locale

First, create the locale directory:

mkdir -p airflow-core/src/airflow/ui/public/i18n/locales/<locale>/

Then update the following configuration files, keeping the existing alphabetical ordering in each file:

airflow-core/src/airflow/ui/src/i18n/config.ts: add the locale to the supportedLanguages array:

{ code: "<locale>", name: "<native name>" },

dev/breeze/src/airflow_breeze/commands/ui_commands.py: add the plural suffixes for the language to the PLURAL_SUFFIXES dict. Check the i18next plural rules for the language at https://jsfiddle.net/6bpxsgd4 to determine which suffixes are needed:

"<locale>": ["<suffixes>"],

.github/boring-cyborg.yml: under labelPRBasedOnFilePath, add:

translation:<locale>:
  - airflow-core/src/airflow/ui/public/i18n/locales/<locale>/*

Scaffolding the translation files

Once the configuration is in place, run the breeze command to copy every English namespace file into the new locale directory. This populates each key with a TODO: translate: stub:

breeze ui check-translation-completeness --language <locale> --add-missing

The generated files will look like this:

{
  "allRuns": "TODO: translate: All Runs",
  "blockingDeps": {
    "dependency": "TODO: translate: Dependency",
    "reason": "TODO: translate: Reason"
  }
}
