Does not recognize SCSS variables

[remotezygote]

The parser gives an error (pasted below) whenever it hits an SCSS variable declaration.

Code to reproduce:

$foo:#666;

Error output:

`- Expected at least 1 of COMMENT / NESTED_RULESET / RULESET at line 1 char 1.

Sounds like it wasn't converted to sass before it ran. What was the filename that this was in? Did it end with a .sass or .scss?

[remotezygote]

It's an SCSS file.

Here's a test you can run:

$ echo "$foo:#666;" > test.scss
$ csscss test.scss

Oddly, now this gets me a new error:

test.scss:1: Invalid CSS after ":": expected pseudoclass or pseudoelement, was "#666;" (Sass::SyntaxError)

Ok, I found the bug in this. If you have a blank file with one new line, csscss bombs on parsing. Oops.

echo "$foo:#666;" > test.scss doesn't actually work because the shell tries to expand $foo

As an example:

/* test.scss file */
$foo: #666;

foo {
  color: $foo;
}

bar {
  color: $foo;
}

∴ csscss -n 1 -v test.scss 
{bar} AND {foo} share 1 rule
  - color: #666666

Ok, I'm going to close this. This will go out in the next release (the one after v1.0.0)

[khelmar]

I'm seeing this issue in v1.3.3:

Sample scss:

@import "./../variables";

$include-html-global-classes: false;
$include-html-reveal-classes: false;

I get the following error:

Had a problem parsing the css at line: 3, column: 1 Failed to match sequence (SPACE? blocks:((COMMENT / IMPORT / NESTED_RULESET / RULESET){1, }) SPACE?) at line 3 char 1.
``- Don't know what to do with "$include-h" at line 3 char 1.

On a side note does csscss work with sass syntax? I'm getting all sorts of issues when trying to run against our sass files. I've been converting to scss and than running csscss.

Thanks

I'm also seeing a problem with nested styles:

.advanced-address-book-recent-ui {
  .queue-template {
    .navigation-arrow-forward {
      display: none;
    }
  }
}

gives:
