occassional occurred information from terminal

[appleyuchi]

I often get the information in terminal:

build_prompt:1: scalar parameter RETVAL created globally in function build_prompt
build_prompt:2: scalar parameter segment created globally in function build_prompt

I don't know how to reproduce it 100%,it just occur occasionally.
Could anyone tell me what happened to my terminal?

A similar issue is found in #438
but they are different

And what makes you think this issue has anything to do with zsh-syntax-highlighting? There's no build_prompt function in zsh-syntax-highlighting. Looks like you should follow up with whoever wrote that function.

$funcfiletrace and friends may be helpful in tracking that one down.

The warning is generated by the warncreateglobal option.

I'm not sure,the reason why I post it here is that
#438 also has build_prompt....
sorry if I put it at the wrong place

[appleyuchi]

could you tell me where should I post it?
I'm weak in zsh,
do you know how to fix it?
it's annoying,
Thanks for your help~!

[danielshahaf]

You should post this to whoever wrote build_prompt.

I don't know who that is. To find out, you can either grep your dotfiles, or set PS4=%x:$PS4 and then the error message will include the filename.

[danielshahaf]

Actually, forget about PS4; it won't help here. My bad.

[danielshahaf]

Note to self: see about exposing a function definition's file:line coordinates via zsh/parameter. The info must be available already, because it's copied into the C funcstack struct at function calls.

[danielshahaf]

Ah, turns out that already exists.

@appleyuchi Run print -r -- ${functions_source[build_prompt]}. That should print the name of the file that defines build_prompt. Tell the author of that file their function isn't WARN_CREATE_GLOBAL-clean. Good luck!

[appleyuchi]

Thanks for
your help。。。。I have fixed for RETVAL
but I can not fixed it for segment.
because segment is defined in a for-loop

[danielshahaf]

I'm afraid we can't help you with that. The zsh-syntax-highlighting issue tracker is not a support forum for arbitrary issues involving arbitrary plugins. Feel free to follow up with the third-party plugin maintainer — I see you've created an issue already (caiogondim/bullet-train.zsh#326) — or with the zsh support forums (#zsh on Freenode and the zsh-users@ list). In the latter case, don't forget to link to the relevant source code.

Good luck!
