LESS (reference) for bootstrap not working as expected

[Amparose]

Importing a reference of bootstrap in its entirety results in cruft at the beginning of one's generated css:

@import (reference) "../bower_components/bootstrap/less/bootstrap";

The resulting css file should be empty.

I have tried this with grunt and it works as expected.

npm ls on your working grunt one, and your broken gulp one. There might be a less version difference

[Amparose]

Good advise! gulp is [email protected] and grunt is [email protected] so that is weird if newer version is "broken". I will have to try and test just lessc and see if it returns the problem with latest version.

@Amparose Check the changelog for less and see if it broke something

Any result?

[Amparose]

Yes, so I just ran command-line less on a file that had only @import (reference) "bootstrap.less"; and the resulting css file was empty as expected.

So to me this indicates that it is a problem with this Gulp module.

Bootstrap v3.0.3

cc @stevelacy didn't you run into this earlier?

[stephenlacy]

Yes, the changelog shows the new 'feature': https://github.com/less/less.js/blob/master/CHANGELOG.md#160

@Amparose What version of the CLI LESS did you use?
I am not sure about the 'problem with this gulp plugin' since it is using the less renderer, all options are passed to LESS:

less.render(str, opts, function (err, css) {
 // css is the rendered less
});

[Amparose]

Which bit is the offending "feature" @stevelacy?

Ok the version of bootstrap I had in my Gulp-enabled project was different to the one I tested with LESSC (my bad). I just tried again with the exact files and get the same issue with LESS 1.6.3, LESS 1.7, and Bootstrap 3.1.1. So apologies, my previous comment (and initial post) was misinformed.

I guess I will reopen this issue with this test case.

Is this still an issue?

closing we are on less 2 now
