Bootstrap output

[Keats]

Bootstrap now compiles without errors (🎊 ) but it produces some invalid CSS as it seems it didn't process everything.

The following bits are present in rsass output:

@extend h1;
@extend h2;
@extend h3;
@extend h4;
@extend h5;
@extend h6;

@extend .container-fluid;
@media (min-width: 576px) {
  %responsive-container-sm {
    max-width: 540px;
  }
@extend %responsive-container-sm;@extend %responsive-container-sm;}

@extend .container-fluid;
@media (min-width: 768px) {
  %responsive-container-md {
    max-width: 720px;
  }
@extend %responsive-container-md;@extend %responsive-container-md;@extend %responsive-container-md;}

@extend .container-fluid;
@media (min-width: 992px) {
  %responsive-container-lg {
    max-width: 960px;
  }
@extend %responsive-container-lg;@extend %responsive-container-lg;@extend %responsive-container-lg;@extend %responsive-container-lg;}

@extend .container-fluid;
@media (min-width: 1200px) {
  %responsive-container-xl {
    max-width: 1140px;
  }
@extend %responsive-container-xl;@extend %responsive-container-xl;@extend %responsive-container-xl;@extend %responsive-container-xl;@extend %responsive-container-xl;}

@extend .container-fluid;
@media (min-width: 1400px) {
  %responsive-container-xxl {
    max-width: 1320px;
  }
@extend %responsive-container-xxl;@extend %responsive-container-xxl;@extend %responsive-container-xxl;@extend %responsive-container-xxl;@extend %responsive-container-xxl;@extend %responsive-container-xxl;}

  content: var(--bs-breadcrumb-divider, escape-svg($breadcrumb-divider)) /* rtl: var(--bs-breadcrumb-divider, escape-svg($breadcrumb-divider-flipped)) */;

So it looks like some extend are not rendered and potentially some variables not replaced?

Yes, bootstrap uses the @extend directive, which is not yet implemented by rsass (see #65 ). And since @extend is not yet supported, it is handled as if it were a css @... rule.

[Keats]

Ah sorry I've missed that. It looks like a big chunk of work I guess, maybe the dart-sass implementation is clearer than the document?

The last one though doesn't seem like a @extend, it looks like a variable hasn't been replaced.

I tested it also but it does not output anything. The CLI just hangs

That shouldn't happen anymore (for any input).

Since release 0.28.0 any use of @extend should give an error message saying that it is not supported yet, instead of writing bogus output.

[CraftSpider]

On 0.28.2, using bootstrap 5.0.2, rsass hangs while importing bootstrap.scss. Based on the find_file stuff printed in the console, it's happening somewhere in vendor/_rfs.scss, and based on debugging it's running one of the while loops in it forever.

Ah, that sass implementation of division does not play well with the arbitrary precision rational numbers used by rsass.
