Vscode format theme support?

[tony-sol]

Is there a way to enable vscode theme format support for bat?
Now, it uses sublime's .tmTheme format, but IMHO it's quite obsolete - sublime now itself supports json format for themes/colorschemes.
Or maybe is there a tool to convert json theme (vscode or sublime) to tmTheme format?

bat cannot load VS Code JSON themes directly. Its highlighter is syntect, and current custom themes must be TextMate .tmTheme files; newer .sublime-color-scheme files are not supported either.

The supported workflow is:

mkdir -p "$(bat --config-dir)/themes"
cp MyTheme.tmTheme "$(bat --config-dir)/themes/"
bat cache --build
bat --list-themes
bat --theme MyTheme file.rs

This limitation is explicit in bat's Adding new themes documentation.

For a VS Code theme, use a converter/exporter that produces a TextMate plist theme, then inspect the result before caching it. Conversion is not always exact: VS Code semantic-token rules and some workbench colors have no equivalent in bat's syntax-highlighting theme, so only tokenColors/TextMate scopes can be mapped reliably. If the theme repository also ships a .tmTheme variant, prefer that over an automated conversion.

After conversion, bat cache --build is required; simply dropping the JSON theme into the folder will not make it appear.
