Am I missing something or does the new yaml-ts-mode not having any rules for indentation? Seems odd in a language where indentation is semantically relevant.

    It does not have indentation at all. It should, but for reasons, it does not. Furthermore, for reasons that strain credulity, it will highlight ERROR nodes with a font lock face, causing endless graphical flashing as you leave your tree-sitter tree in a brief error-state as you type.

    I recommend you ditch it unless you have a good reason for using it. The third-party yaml-mode.el is excellent.

      I was afraid that this was the case; I’ve been trying to pare down on packages that I only occasionally use to reduce the complexity of my config, but this doesn’t seem like a good thing to compromise on.

      It seems to be only a very rudimentary implementation of a yaml major mode. The only thing that it does better is that it works faster and seems to do more consistent highlighting. And I actually like what you describe as “graphical flashing” because it gives you immediate feedback when something is wrong. Yet I admit it is annoying too. Also, yaml-mode indentation while better still needs getting used to in comparison to other modes. I am back at using yaml and yaml-pro.

      Thanks for the link; I read this discussion as well but couldn’t be too sure about the impact. I made a copy of the yaml-ts-mode.el and switched it to be derived from prog-mode, but it had no effect on the indentation sadly.
