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.
GNU Emacs 29.1 (build 2, x86_64-unknown-linux-gnu, GTK+ Version 3.24.38, cairo version 1.16.0) of 2023-08-03
Treesitter grammar installed and loaded via:
(use-package treesit-auto
:config
(add-to-list 'global-treesit-auto-modes '(not org-mode))
(setq treesit-auto-install t)
(global-treesit-auto-mode))
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.
There was quite a debate on wether it should inherit prog-mode here, maybe the fact that it does not is the cause of what you describe ?

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.eland switched it to be derived fromprog-mode, but it had no effect on the indentation sadly.
