Scaffold not preprocessing css?

@brino,

Things to verify :

- Have you included the stylesheet file using scaffold[all][] syntax ?
- Have you tried with a minimal stylesheet to ensure it has no parsing error ?
- If it still does not work, you may want to manually fill the Document root value in admin/settings/scaffold.

You may also try the dev version since it has some bugfixes.

That's an interesting issue, other themes may do the same, I'll see if this issue can at least have a workaround by tweaking the theme, and if so add instructions in the README.txt file.

Hi brino,

Hey, thank you for the beer proposal, but yes, probably not in the US ;) Not even Copenhaguen, I won't be there neither, but some day maybe ;)

To track down the problem, could you tell me :

- What you do exactly ? Use Tao and modify it to add a scaffold stylesheet ? Use it as a base theme ?
- Could you use a very simple stylesheet, like this one :

@constants {
  test: #FF0000;
}
body {
  color: $test;
}

And see if the stylesheet is processed ?
- Ensure you checked "Development mode" and disabled Drupal css aggregation.

I haven't tried this yet but I'm also using Tao so I'll subscribe.

Need more info for this.

Same problem with Zen2-based theme, Scaffold 2.2

I quickly looked at the Tao template.php file, and the "styles" variable seems only affected for print stylesheet, so that's not the cause of the problem.

If you have the issue, please try with a modified Garland theme with the minimal stylesheet provided in my previous comment to see if the problem really comes from the theme.

Subscribing... :)

Building a new subtheme of tao and I'm having the same issue. Replaced my stylesheet with the minimal from #8 and still having trouble, switched base theme to garland and it worked fine. Anyone have info on a workaround until a real solution is found?

I've recently built a subtheme of Rubik, which is itself a subtheme of Tao. To use with Scaffold I had to put this in my theme's template.php:

/**
 * Implementation of hook_preprocess_page().
 * 
 * This fires before Tao's implementation, so we can trap the special set of
 * styles that the Scaffold module prepared.
 */
function phptemplate_preprocess_page(&$vars) {
  if (preg_match('@^.*?/scaffold([^?"]+).*$@m', $vars['styles'], $matches)) {
    $scaffold_files = explode(',', $matches[1]);
    _mytheme_stash_scaffold_styles($matches[0], $scaffold_files);
  }
}

/**
 * Implementation of hook_preprocess_page().
 * 
 * This fires AFTER Tao's implementation, so we can restore our stashed styles.
 */
function mytheme_preprocess_page(&$vars) {
  list($scaffold_line, $scaffold_files) = _mytheme_stash_scaffold_styles();
  
  if ($scaffold_files) {
    $styles = $vars['styles'];
    foreach ($scaffold_files as $file) {
      $pat = '@^.*?'.$file.'.*$@m';
      $styles = preg_replace($pat, '', $styles);
    }
    $vars['styles'] = rtrim($styles) . "\n$scaffold_line\n";
  }
}

/**
 * Utility function to statically cache the scaffold files so we can fix the
 * styles after Tao mangles them.
 */
function _mytheme_stash_scaffold_styles($line = NULL, $files = NULL) {
  static $scaffold_files, $scaffold_line;
  
  if ($line && is_array($files)) {
    $scaffold_line = $line;
    $scaffold_files = $files;
  }
  
  return array($scaffold_line, $scaffold_files);
}

The offending code in Tao is found in tao_preprocess_page(), specifically where it replaces the styles with stuff it gets from tao_css_stripped().

NOTE: My code in #15 does not work with CSS aggregation. I'll be tackling that eventually, though. ;)

Okay, so in looking at this to share, I realized this can be so much easier. Put this in your theme:

function mytheme_preprocess_page(&$vars) {
  $vars['styles'] = _scaffold_get_css(tao_css_stripped());
}

This keeps Tao's CSS wrangling AND lets Scaffold process (and aggregate) its CSS files.

Josh, thanks for the feedback, it will be useful to add to README.txt. And yes, indeed, the second snippet is much easier :)

But LESS has no problems with these themes.

FYI... I just created an Tao subtheme and everything seems to be working fine for me so far.
