Eglot eglot-ensure doesn't work on some mode hooks (but not others)

[alexispurslane]

So I've got a couple file types set up to eglot-ensure:

(add-hook 'rust-ts-mode-hook 'eglot-ensure)
(add-hook 'typescript-ts-mode-hook 'eglot-ensure)
(add-hook 'js-ts-mode-hook 'eglot-ensure)
(add-hook 'python-ts-mode-hook 'eglot-ensure)

This works perfectly fine with Rust and Python, but with JavaScript and TypeScript files, nothing happens. No errors, but also no eglot. Nothing whatsoever at all. But if I then manually run M-x eglot, sure enough, it works just f-n fine.

It's hard to tell what is going on given only add-hook statements.

Since M-x eglot works as expected, this does not seem to be a problem related to Eglot itself, but reading the Troubleshooting section of the manual would not hurt.

Would you be able to provide a recipe from emacs -Q to reproduce the problem?

Yes actually, since I was able to repro this problem with a completely clean emacs config — give me a bit and I'll provide it. Apologies for the lack of clarity

Also, eglot ensure actually doesn't work with rust or python either on that fresh config, so at least it is consistent.

@alexispurslane any news on the recipe from emacs -Q?

[alexispurslane]

Oh shit I totally forgot, I got so used to manually triggering eglot!

Okay, upon trying it out, now it's working in both emacs -Q and my config. Not sure what the difference is. Apologies!

Yeah :-D Personally I never use eglot-ensure myself, once you realize that M-x eglot survives all the way to the lifetime of a project, you probably don't mind typing it, like, once a day. eglot-ensure is supported, but is much more brittle and error-prone.

Good to know
