%N in prompt shows "_zsh_highlight_call_widget" on Ctrl-L instead of e.g. "/usr/bin/zsh" or "-zsh" since recently

[xtaran]

I'm not sure since when this happens, but that part of my prompt hasn't changed for quite a while and this happens for a few weeks now, maybe since the z-sy-h 0.5.0 release or since the zsh 5.3 release, but at least with the combination of z-sy-h 0.5.0 and zsh 5.3.1:

Everytime I press Ctrl-L in my xterm, %N inside my prompt shows _zsh_highlight_call_widget instead of e.g. /usr/bin/zsh or -zsh:

Normal prompt:

!5334 Z5 ?0 L1 user@host:~ (pts/39 -zsh 5.3.1 stretch) 21:35:56 
~ → 

After Ctrl-L:

!5334 Z2 ?0 L1 user@host:~ (pts/39 _zsh_highlight_call_widget 5.3.1 stretch) 21:36:18 
~ → 

How to reproduce:

~ → zsh -f
host% . /usr/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh 
host% PS1='%N %% '
zsh % ^L
_zsh_highlight_call_widget % 

I'm not sure if this is an issue with z-sy-h or if I should just not expect %N to always show zsh (with or without path and or the dash indicating a login shell) and should just use $0 instead of %N.

Hello Axel!

``` ~ → zsh -f host% . /usr/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh host% PS1='%N %% ' zsh % ^L _zsh_highlight_call_widget % ```

I can reproduce this without z-sy-h: ```zsh $ zsh -f % clear-screen() { zle .$WIDGET -- "$@" } % zle -N clear-screen % PS1='%1N %# ' zsh % <^L> clear-screen % ``` That's with zsh master; with zsh 5.0.7 from debian stable, the last prompt says "zsh", …

should just use `$0` instead of `%N`.

… so this is an upstream change. I am not sure whether it's a regression or a bugfix. Is a change on z-sy-h's side needed? (I quickly grepped upstream's git, but haven't found anything yet)

I can reproduce this without z-sy-h:

Oh, I didn't think of trying that after I saw one of z-sy-h's function names in there.

… so this is an upstream change. I am not sure whether it's a regression or a bugfix.

Yes, I see it now that way, too. Will report it on zsh-workers.

Is a change on z-sy-h's side needed?

I have no idea. Feel free to close the issue, if you want.
