bug: `declare: -A: invalid option` even with BASH `GNU bash, version 5.2.37(1)-release`

[jameskim0987]

When trying to test the example mygrep on my machine which is a macOS with bash version GNU bash, version 5.2.37(1)-release, I'm getting the following error.

$ mygrep -bash: declare: -A: invalid option
declare: usage: declare [-afFirtx] [-p] [name[=value] ...]
-bash: declare: -A: invalid option

Has anyone else faced a similar issue before?

Hi, this answer looks relevant: https://stackoverflow.com/a/43948526

Could it be that you're using a different bash version for completing than the one you're checking the version of?

[adaszko]

What happens when you modify the completion script to print the bash version from within it?

[jameskim0987]

@adaszko Thanks for getting back. That stackoverflow link was what I was referencing before opening the issue. The bash version on the system was updated correctly but it looks like it was missing a machine restart. After a couple restarts, it looks like the issue is gone!

Closing issue.

[adaszko]

I will add a version check to the generated script. I learned that it can be an issue on macos so thanks for reporting anyway!

[jameskim0987]

Sounds good!
