How to indicate bash style syntax checking in sourced files

[moreaki]

When sourcing a library from an explicitly written bash script, I'd like to hint/indicate inside Intellij to BashSupport Pro that my library file is actually written in bash style and not POSIX sh. Otherwise I have all these warnings:

I'm sure there is a switch somewhere, but I couldn't find it.

@moreaki Do I understand the setup correctly that the screenshot displays the library file?
If so, you could change line 2 to # shellcheck source=../.sigma-config.sh shell=bash` to tell BashSupport Pro and ShellCheck that the file is Bash and not POSIX. Without the directive, the file extension is used to guess the type of shell.
All directives are listed at https://github.com/koalaman/shellcheck/wiki/Directive#shell

Does this work for you?

Thinking further, it might be a good feature to offer mark file as Bash if a file is detected to be sourced by a Bash file.

Yes, you understood everything perfectly! Thank you so much for the great support. I have added it, however I don't know how to trigger a re-evaluation of the file from a BashSupport Pro point of view inside Intellij. Also, a restart did not trigger it on my side:

I love the idea of mark file as Bash in Intellij. Please consider supporting this.

Found the issue:

When shell=bash is set as indicated by 1, it works, with 2 it does not. I suppose your parser tries to be extra intelligent ;).

Ah, I see.
AFAIK the shell directive always applies to the whole file and file-level directives can only be applied in the file-header comment (as specified on the page I linked). But as ShellCheck‘s documentation isn‘t entirely clear here, I need to double-check if my implementation matches ShellCheck‘s. But I‘m 90% sure it does…

A shell directive in the middle of a file would require to parse some parts as Bash syntax and the others as POSIX. That‘s not supported by BashSupport Pro and AFAIK also unsupported by ShellCheck.

rl;dr I think the top-level directive is the only way to override the file type of a file.

Great, so if that's the case, let's improve the documentation for shellcheck ;).

Thank you for your swift support. I'm glad I bought the subscription a couple of years ago. Hope your revenue stream allows you to continue this wonderful plugin.
