ctrlf-mode breaks search in find-file and switch-buffer about ctrlf

[raxod502]

I think you mean C-x C-f followed by M-r, because in vanilla Emacs C-x C-f followed by C-r just does an Isearch on the current contents of the minibuffer, without any interaction with history. Let me know if I guessed wrong here.

Anyway, I pushed a commit that should fix all the compatibility issues. Let me know if it works for you.

(I'm assuming you are using Selectrum, because otherwise I can't think of any reason M-r would not work. See radian-software/selectrum@551b119.)

Multiple separate but related problems here with both ctrlf and selectrum, I'm not exactly sure how to keep the conversation organized between this and radian-software/selectrum#4, but I'll try. :)

No, it definitely interacts with history! When used in find-file, C-r does a search through file-name-history, not the default minibuffer-history. I'll comment on that further in the other ticket.

The breakage I'm referring to here occurs when ctrlf is the only package installed in an Emacs sandbox (no configuration, naturally). Steps to reproduce:

1. enable ctrlf-mode
2. C-x C-f
3. C-r errors out: ctrlf--start: Command attempted to use minibuffer while in minibuffer

The expected result is incremental search through file-name-history. It's okay to fall back on isearch-backward here rather than ctrlf-backward-*.

Okay. Thanks for the explanation. This is bizarre to me because I cannot find the code that implements this behavior anywhere in Isearch. It would be helpful if someone could point to the implementation. That would help to determine why using Isearch within Selectrum breaks ("text is read-only" error).

[raxod502]

I guess that's a separate issue, though, from CTRLF overriding the bindings which also breaks usage without Selectrum. Open a new issue against Selectrum if it bothers you; the bug you reported here should be fixed.
