Proposal

Add a banner.scss (or maybe name it copyright.scss or license.scss to avoid confusion) that only contains the copyright information for cherry-picking imports with copyright information.

Motivation and context

I have projects that are cherry-picking a only few scss files from bootstrap to be imported.

I want to properly include the bootstrap copyright header but there is no easy way to do so right now other than manual copy-paste the copyright banner.

@ntkme comment unusable files(// ...) in bootstrap.scss and run npm run dist

@WinterSilence I'm directly importing files from node_modules/bootstrap/sass/... so that won't work.

[WinterSilence]

@ntkme than import/run https://github.com/twbs/bootstrap/blob/main/build/banner.js too

[ntkme]

@WinterSilence That won't show a copyright comment in the result css file. Also this is for a pure CSS project, there is no JS bundler anyways.

[WinterSilence]

@ntkme that's script generate summary comment - you can use it anywhere. "pure CSS project" still use python/ruby for compile scss

[ntkme]

@WinterSilence You cannot import a JS file when scss are compiled using ruby's sassc gem or sass-embedded gem, because they are just scss compilers, but not bundlers like webpack or rollup. There is no way to cross import/reference JS/SCSS in such simple setup.

@ntkme I'm not against your suggestion. I'm talking about how to get a similar result now.
