Supported languages and themes

To list the supported languages and color themes, use delta --list-languages and delta --list-syntax-themes. To see a demo of the color themes, use delta --show-syntax-themes:

To add your own custom color theme, or language, please follow the instructions in the Customization section of the bat documentation:

• Adding a custom language
• Adding a custom theme

Delta automatically recognizes custom themes and languages added to bat. You will need to install bat in order to run the bat cache --build command. Ideally, the version of bat you install should match the version specified in delta's Cargo.toml for the delta release you're using. There are known problems with bat v0.18.3 and below.

The languages and color themes that ship with delta are those that ship with bat. So, to propose a new language or color theme for inclusion in delta, it would need to be a helpful addition to bat, in which case please open a PR against bat.
