The DeepL CLI tool supports a wide range of languages for translation. You can view the full list of supported languages directly from the command line using the `deepl --languages` flag.
To get an up-to-date list of all languages supported by the DeepL API, run the following command:
deepl --languages
This command will output a list of language codes and their corresponding names, similar to this:
Supported DeepL Languages:
--------------------------
en: English
fr: French
de: German
es: Spanish
...
The language codes (e.g., `en`, `fr`, `de`) are used with the `-s` (source) and `-t` (target) flags when performing translations.
For the most comprehensive and up-to-date list of supported languages, including any specific nuances or limitations, always refer to the official DeepL API documentation on Supported Languages.
