Support globs on the command line

[tomByrer]

Latest Sass on both Windows & OSX I get the following error

video.js@7.5.0 build:css:cdn: sass src/css/vjs-cdn.scss dist/alt/video-js-cdn.css "--watch" "'src/**/**/*.scss'"

This command works fine as-is in node-sass, but errors out in dart-sass. I would expect only a warning & ignoring the (unused) parameter.

Removing the parameter works well.

Perhaps the project I'm working on is unusual; older codebase but doesn't use grunt/gulp, but uses CLI commands in package.json (which is more of a current trend).

It looks like you want to be able to pass a glob (src/**/**/*.scss) to Dart Sass that it natively handles? That's something we could probably add.

@nex3 would support for globbing become a core, built-in feature of the language or would it be handled via plugins, like Ruby Sass?

[nex3]

It would be part of Dart Sass's command-line API, so... neither.

What about a glob() function that returns a list?

[bdkjones]

I've dug into this a bit. @nex3 suggested using the Dart API, the JS API, or the Embedded Sass protocol to declare a custom importer that would resolve glob statements. But, looking at the Dart Sass source, I don't see a way for an importer to say, "This @import statement resolves to these 5 files: /path/to/file1.scss, /path/to/file2.scss, etc."

In fact, the Dart Sass source has comments that explicitly instruct importers to throw an exception if an @import statement resolves to more than one file.

I am not fluent in Dart, and would not be surprised at all if I've missed something. But it seems like DartSass will need some changes to relax the "1 @import statement matches 1 file" assumption before globbing can be supported in any way?

[bdkjones]

I should also add: I don't like globbing and I think the Sass team was right to reject it as a first-party feature years ago. But, folks use globs constantly in the config files for gulp/grunt/webpack/npm, so they have become pervasive.

Also: I realize this issue is about passing input files to the CLI specifically and I'm discussing globs for @import/@use. Because Sass rejected globbed imports years ago, I didn't want to clog the repo with a separate issue for it.

[nex3]

I mentioned this in passing in another thread, but for completeness: if you wanted to support a globbing importer, you'd need to have it return the contents of a synthetic file that contained explicit imports of all the files matching the glob.

Would be very nice to be able to do:

sass "sources/scss/*/main.scss" assets/bare/

And have sources/scss/foo/main.scss compile to assets/bare/foo/main.css
