Ability to @import from webjars

[be9]

I wonder if there is any possibility to do

@import 'bootstrap';

having [org.webjars/bootstrap "3.3.6"] in dependencies.

If that's not possible, what's the preferred way to pull 3rd party modules?

I think something like this could work with [org.webjars.bower/bootstrap "4.0.0-alpha.2"]:

(comp
 ; Add files from Bootstrap webjar to fileset
 (sift :add-jar {'org.webjars.bower/bootstrap #"META-INF/resources/webjars"})
 ; Move files to sane path:
 ; e.g. META-INF/resources/webjars/bootstrap/4.0.0-alpha.2/scss/bootstrap.scss => bootstrap/scss/bootstrap.scss
 (sift :move {#"^META-INF/resources/webjars/bootstrap/[^\/]*/" "bootstrap/"})
 (sass))

@import 'bootstrap/scss/bootstrap`;

This seems like a step into the right direction, however doesn't work.

[org.webjars/bootstrap "4.0.0-alpha.2"] in dependencies (org.webjars.bower/bootstrap gave me a NPE for some reason).

Here's the task:

(deftask mysass []
  (comp
    ; Add files from Bootstrap webjar to fileset
    (sift :add-jar {'org.webjars/bootstrap #"META-INF/resources/webjars"})
    ; Move files to sane path:
    ; e.g. META-INF/resources/webjars/bootstrap/4.0.0-alpha.2/scss/bootstrap.scss => bootstrap/scss/bootstrap.scss
    (sift :move {#"^META-INF/resources/webjars/bootstrap/[^\/]*/" "bootstrap/"})

    (sass :output-dir "stylesheets")
    (target :dir #{"target"})))

Here's the output:

You can try https://github.com/Deraen/sass4clj

It has built-in support for importing files from classpath and webjars.

For cases like this, I definitely recommend https://github.com/Deraen/sass4clj

@Deraen @mathias thanks for the advice, I had success with sass4clj.

I think the difference between the both should be somewhere on the wiki. Is boot-sassc expected to work faster as it just shells to sassc executable?
