screenshot of ide text editor

Many SCSS files display "Unexpected token" errors of different kinds. This would not be critical except that it prevents Netbeans from using editor colours, document links, folding and all other IDE enhancements for any code after the errors (in some cases).

This code is one such error:

@each $ord in 1, 2, 3, 4 {
	body._#{$ord} #page {
		background: $page-bg url(#{$scssDir}/images/bg#{$ord}-squares-blue.png);

This produces valid CSS when parsed by scssphp, but prevents Netbeans from implementing any advanced text editing features after it, as can be seen in the attached image.

Here is the list of unexpected tokens found in the code (all but 'RBRACE' are from the 'background: ...' line):

Let me know if you require any more detailed information from me
Comment 1 Vladimir Riha 2013-12-02 09:42:33 UTC
Reproducible, thank you for reporting. As a workaround, you can close it in quotes

background: $page-bg url('#{$scssDir}/images/bg#{$ord}-squares-blue.png');

Comment 8 Milutin Kristofic 2015-04-17 10:42:48 UTC
Please try this in sass file:

@function composeURL($a, $b)
    @return url($a + $b);

=> line with url(..) is underlined, with unexpected token ERROR, SEMI and RPAREN. If I remove white spaces to

@function composeURL($a, $b)
    @return url($a+$b);

then error is gone but it is not recognized as variables (different color of $a and $b in braces, mark occurrences does not work

Another example from my LESS file:

li {
    background: transparent url(@{img_path}list-bullet.png) no-repeat 0 0;
				padding-left: 14px;
				margin-bottom: 5px;

The hint shows up on the background tag.

Comment 12 Milutin Kristofic 2015-09-16 10:41:48 UTC
Yes, thank you for more examples. I know that are many problems with how url doesn't parse in LESS, SASS. I will find a way in next release.

Comment 15 Milutin Kristofic 2015-12-01 13:27:51 UTC
I made quick fix for url, so we accept almost anything in url(). It is not ideal solution, but better than having always error. only case this doesn't fix is following:url(add($a,$b)This change means that it parses some strings it should not. I will leave this open for better solution.

Comment 17 senendds 2016-02-02 17:15:43 UTC
Another error, not related with url().

The code

  .serif(@size: @baseFontSize, @weight: normal, @lineHeight: @baseLineHeight) {
    #font > .shorthand(@size, @weight, @lineHeight);

produces an "Unexpected token GREATER found" warning in the last line.
Comment 18 Christian Lenz 2016-02-17 13:31:22 UTC
Same for the src attribute for font faces when there is an "if" inside the url:

@font-face {
    font-family: 'myFont';
    src: url(if($bootstrap-sass-asset-helper, twbs-font-path('#{$icon-font-path}#{$icon-font-name}.eot'), '#{$icon-font-path}#{$icon-font-name}.eot'));
    font-weight: normal;
    font-style: normal;
