Bug? (babelrc options not work) + Use case (need to pass fn to plugin options)

[eventualbuddha]

Thanks for the issue. I was confused by this for a bit because I never use the --find-babel-config option myself. The problem is that when you use --find-babel-config you're telling Babel to use the .babelrc.js file and to load all the plugins mentioned in it. Then you're also telling codemod to load the babel-plugin-replace-import plugin, but without providing options properly. The end result is that Babel tries to process your code with the plugin twice, once with the right options and once without. That's the the last example you provided, using @codemod/core directly, worked as expected -- you weren't telling Babel to load the plugin.

This could certainly be improved from a documentation perspective, and maybe something in tooling as well. One way might be to allow loading plugin options from JavaScript files, like this:

codemod -p babel-plugin-replace-imports -o @bpri-opts.js js/libs/navi.js

Would that be useful? Or would you just prefer to keep it in .babelrc.js and run like this?

codemod --find-babel-config js/libs/navi.js

thank you for clarification! 🙏
-o @bpri-opts.js would be perfect for my case

p.s. currently i've complete my task already (using var { transform } = require('@codemod/core'), glue and gulp)
and looks like it could be done using cli with target plugins inside config and dummy plugin (if -p is required), is it correct?
