shellcheck config not used

[altendky]

When actionlint is extracting a run: string from a workflow file the shellcheck config is not respected. I'm guessing that either the string is piped directly into shellcheck or located in a tmp directory outside of the project structure. Normally I would consider this good but since shellcheck (afaik) looks for the config based on the location of the script being analyzed, this could be making it not find the project config.

Yes. The config file is intentionally not referred (--norc option passed to shellcheck). Instead you can use SHELLCHECK_OPT to pass options to shellcheck process.

I am interested in using the same config for all shell scripts, inside a workflow or as a standalone file. Certainly, in some cases different configurations would be wanted, but defaulting to the same seems useful.

As far as any potential implementation, I could imagine an argument that shellcheck should first grow a feature like --search-for-rc-from and you can pass a file or directory to use for the config search instead of the file passed for checking. I don't know if they would argue against this or not.
