wrong-type-argument error when using swiper-helm

[iswanz]

My beloved swiper-helm has stopped working since a recent update. Swiper works fine.

I get the error:
Error during redisplay: (eval (helm-show-candidate-number (car-safe helm-mode-line-string))) signaled (wrong-type-argument integer-or-marker-p nil)

The swiper-helm buffer narrows as a I type, but when I try and move the selection (using any of the arrow keys) it jumps to the bottom of the swiper-helm buffer and then won't move.

Some debug information:

Thanks for your help!

swiper-helm hasn't been updated for months. I just checked with helm-20160808.2223 and Emacs 25, swiper-helm still works fine: narrowing works and the arrow keys work.

Error during redisplay: (eval (helm-show-candidate-number (car-safe helm-mode-line-string))) signaled (wrong-type-argument integer-or-marker-p nil)

This error does not originate in swiper-helm source. Just update helm, hopefully it goes away.

I have the same problem.
helm works fine but moving up/down in swiper-helm is not working correctly.

I tried it with emacs-24 and now emacs-25.1.
helm version is 20160814.522.

install-deps.txt

Try to reproduce with:

emacs-24.5 -Q -l install-deps.txt

M-x swiper-helm, t h, C-n C-p. Works fine for me.

[dakra]

Hmm.. when I start with emacs -Q -l install-deps.txt swiper-helm works perfect so I guess it's not a swiper-helm issue.
Any tips how I could find out what's causing this? Starting with --debug-init (or starting normal) doesn't show any error messages.

[abo-abo]

@dakra Thanks for confirming.

Any tips how I could find out what's causing this?

This type of bug is easiest to solve by bisecting your config. Using install-deps.txt is like commenting out your whole config. What you need to do now is to comment out just about a half, while keeping swiper-helm loading. Check if the bug is there. Either way, you know in which half of the config it is. Now take that half and half it once more. Keep going until you find the problem line.

Just a quick update if someone has the same problem.
For me it was not a particular package or misconfiguration.
I just had to recompile my packages and then it worked.
So (byte-recompile-directory package-user-dir nil 'force) fixed it for me ¯_(ツ)_/¯

[abo-abo]

¯_(ツ)_/¯

^. Problem solved:)

Sorry for delay in responding. I tried @dakra 's suggestion of using:

(byte-recompile-directory package-user-dir nil 'force)

and that didn't work for me, so I went through @abo-abo 's process of bisecting my .emacs and found that the problem (for me) was minimap. By adding that package to @abo-abo 's minimal install script I can reproduce the error. I've attached the updated script, which I ran using:

emacs -Q -l install-deps-with-minimap.txt

install-deps-with-minimap.txt

The same problem occurs for me with helm-swoop. A bit of duck-ducking found that a similar issue was reported with that package and neotree.
