strange behavior when using 'setopt ignoreeof' and zsh-syntax-highlighting

[400thecat]

I have setopt ignoreeof at the beginning of my .zshrc file. Normally, when I pres ctrl+d I get following message: zsh: use 'exit' to exit. That is desired behavior.

Now when I source sh-syntax-highlighting in .zshrc, suddenly ctrl+d behaves weird. When I pres ctrl+d I get a list of all available commands, and at the bottom of the screen At Top: Hit TAB for more, or character to insert.

This is another variant of issue #245. The fix to this issue is to be merged soon, however, it requires zsh 5.3. Until then, you can try the following workaround:

ctrl-d() { zle -M "zsh: use 'exit' to exit."; return 1 } 
zle -N ctrl-d

Put that in your .zshrc before sourcing z-sy-h. (I tried just bindkey -r "^D", but that removed the use 'exit' to exit message as well.)

For future reference, the message you got is because Ctrl+d also serves as a "list completions" binding; it is bound to the delete-char-or-list widget, not to delete-char.

Sorry, that example was incomplete. It needs another line:

ctrl-d() { zle -M "zsh: use 'exit' to exit."; return 1 } 
zle -N ctrl-d
bindkey '^D' ctrl-d

Fixed on the feature/redrawhook branch.

Under the same conditions as OP (sending EOF while using the IGNORE_EOF Zsh option), I get a list completion behavior.
zsh: do you wish to see all 3000 possibilities (800 lines)?

The aforementioned solution mentioned by @danielshahaf works; so I’ll be using it for now, but it seems silly to use instead of using setopts IGNORE_EOF.

Should I open a new issue referencing this one?

I can't reproduce this. Starting from zsh -f

setopt ignoreeof
. <path to z-sy-h>
<ctrl-d>

I get the zsh: use 'exit' to exit. message. zsh 5.9 and z-sy-h 0.8.0.
