Mixins parse error : Unrecognised input with twitter/bootstrap latest master

[neilime]

I got this error on line 578 when i try to compile mixins.less file (latest master) :

    .spanX (@index) when (@index > 0) {
      .span{@index} { .span(@index); } // Here is the error
      .spanX(@index - 1);
    }

Lessphp version used : latest master

The Code should be like this:

.spanX (@index) when (@index > 0) {
    (~".span@{index}") {
        .span(@index);
    }
    .spanX(@index - 1);
}

This is how it is documented http://leafo.net/lessphp/docs/#selector_expressions

But this code is from twitter/bootsrap and it works with less.js

You sure you are on master? I fixed this issue a little while ago ee5b675

Yes I saw that a patch has been made, but when I run the test below with the latest master version, I got this error :
Uncaught exception 'Exception' with message 'parse error: failed at{ .span(@Index); } line: 6'

include 'leafo/lessphp/master/lessc.inc.php';
$oLessc = new lessc();
$oLescc = $oLessc->compile('
.span (@columns) {
  width: @columns;
}
.spanX (@index) when (@index > 0) {
  .span{@index} { .span(@index); } // Here is the error
  .spanX(@index - 1);
}
');

You have a syntax error, it's @{index} instead of {@index}. Fails even in lessjs.

You're right, I don't know why I have this error in the code. Sorry for this useless issue.
