I'm using the lsp layer on Spacemacs with javascript-backend 'lsp and it activates two modes I don't like: lsp-ui-mode and eldoc.

I found lsp-ui-mode inside lsp-mode-hook and added (remove-hook 'lsp-mode-hook 'lsp-ui-mode) to my init.el, which fixed that.

But I can't find where eldoc-mode is being called. How do I search for it within (all?) hooks?

Use M-x debug-on-entry RET eldoc-mode RET

(and M-x cancel-debug-on-entry RET to undo that.)

This will show you what called eldoc-mode, each time it is invoked.

To learn about the debugger, see C-hig (elisp)Debugger and especially (elisp)Debugger Commands (so you know how to use it).

In this case, the cause is almost certainly global-eldoc-mode which is a globalized minor mode. Globalized modes act in after-change-major-mode-hook, which happens after the major mode hook has run (and so you can't use the major mode hook to disable the associated buffer-local eldoc-mode).

If you don't want eldoc at all, just add (global-eldoc-mode -1) to your init file.

    Thank you, debug-on-entry did it. I added (global-eldoc-mode -1) to my init file but it wasn't enough. Then through the debugger I found out I had to also set lsp-enable-eldoc nil. Also found lsp-ui-doc-enable and lsp-ui-sideline-enable and turned them off to stop annoying overlays on hover. Commented Sep 7, 2018 at 0:57

You can use command apropos-value to find all variables whose values match some pattern: M-x apropos-value eldoc-mode. Then search the results buffer for just the variables whose names end in -hook.

  • Thank you! This does exactly what I asked for, but it was less helpful as there were too many results and I couldn't sift through them to find the culprit. Using debug-on-entry I also found out that eldoc-mode wasn't getting called in a hook at all, but rather in a piece of code that checked for the lsp-enable-eldoc condition and then called eldoc-mode directly.
