tolgaulas Hello, the current options does not include Codemirror in _files/js/custom.js, can we have controls of it, like adding linters (i.e yaml) and not saving when linter fails?
Ok, I will look into exposing the CodeMirror configuration in Files Gallery custom Javascript, although I can't guarantee everything will work perfectly with the Files Gallery- specific implementation of CodeMirror.
tolgaulas Also, can codebase optionally be replaced with ACE may be, with config?
Probably not unfortunately. Files Gallery is an opinionated application, where a lot of effort is put into making it look and work nicely with selected tools and plugins. This may be possible in other file managers, which have less emphasis on retaining a clean and consistent interface design. Too many options means too much clutter we can't control. Why Ace editor btw?
