RFE: variant of source= directive that supports globbing

[intelfx]

For new checks and feature suggestions

• https://www.shellcheck.net/ (i.e. the latest commit) currently gives no useful warnings about this
• I searched through https://github.com/koalaman/shellcheck/issues and didn't find anything related

Here's a snippet or screenshot that shows the problem:

There is a pattern common to relatively large shell programs of loading multiple files with subroutines from a "library" directory, e.g.:

MAKEPKG_LIBRARY=${MAKEPKG_LIBRARY:-'@libmakepkgdir@'}

# Import libmakepkg
for lib in "$MAKEPKG_LIBRARY"/*.sh; do
	source "$lib"
done

Here's what shellcheck currently says:

Shellcheck gives a single SC1090 at the source site, which is expected:

ShellCheck can't follow non-constant source. Use a directive to specify location.

However, this is not helpful because a source= directive cannot be used to specify that multiple files should be imported at a single import site.

Here's what I wanted or expected to see:

I would like ShellCheck to have a directive (e.g. source-glob= or perhaps source-list= for especially complex cases) that would allow the user to specify that multiple files should be imported at this site:

for lib in "$MAKEPKG_LIBRARY"/*.sh; do
	# shellcheck source-glob=libmakepkg/*.sh.in
	source "$lib"
done

A question might arise on how to handle such directives inside loops; perhaps the answer (if ShellCheck does not do this already) is to only process this directive exactly once per source site.
