Bootstrap - Sass: relative glyphicons icon path

Question

How do I set a relative glyphicons icon path in bootstrap sass version?

By default, the path used in the css font-face is an absolute one.

@font-face {
  font-family: 'Glyphicons Halflings';
  src: url(/fonts/bootstrap/glyphicons-halflings-regular.eot?1422262129);
  src: url(/fonts/bootstrap/glyphicons-halflings-regular.eot?&1422262129#iefix) format("embedded-opentype"), url(/fonts/bootstrap/glyphicons-halflings-regular.woff2?1422262129) format("woff2"), url(/fonts/bootstrap/glyphicons-halflings-regular.woff?1422262129) format("woff"), url(/fonts/bootstrap/glyphicons-halflings-regular.ttf?1422262129) format("truetype"), url(/fonts/bootstrap/glyphicons-halflings-regular.svg?1422262129#glyphicons_halflingsregular) format("svg");
}

But I need a relative one: "../fonts/bootstrap" - so in file _bootstrap-variables.scss, I set the $icon-font-path

$icon-font-path: "../fonts/bootstrap/"

which gives the following

@font-face {
  font-family: 'Glyphicons Halflings';
  src: url(/fonts/../fonts/bootstrap/glyphicons-halflings-regular.eot?1422262129);
  src: url(/fonts/../fonts/bootstrap/glyphicons-halflings-regular.eot?&1422262129#iefix) format("embedded-opentype"), url(/fonts/../fonts/bootstrap/glyphicons-halflings-regular.woff2?1422262129) format("woff2"), url(/fonts/../fonts/bootstrap/glyphicons-halflings-regular.woff?1422262129) format("woff"), url(/fonts/../fonts/bootstrap/glyphicons-halflings-regular.ttf?1422262129) format("truetype"), url(/fonts/../fonts/bootstrap/glyphicons-halflings-regular.svg?1422262129#glyphicons_halflingsregular) format("svg");
}

In the web I found the tip to inlcude "bootstrap-sprockets" before the variables, the result is

@font-face {
  font-family: 'Glyphicons Halflings';
  src: url(font-path("../fonts/bootstrap/glyphicons-halflings-regular.eot"));
  src: url(font-path("../fonts/bootstrap/glyphicons-halflings-regular.eot?#iefix")) format("embedded-opentype"), url(font-path("../fonts/bootstrap/glyphicons-halflings-regular.woff2")) format("woff2"), url(font-path("../fonts/bootstrap/glyphicons-halflings-regular.woff")) format("woff"), url(font-path("../fonts/bootstrap/glyphicons-halflings-regular.ttf")) format("truetype"), url(font-path("../fonts/bootstrap/glyphicons-halflings-regular.svg#glyphicons_halflingsregular")) format("svg");
}

The url itself seems ok - but where does this "font-path" come from, how do I get rid of it?

Or is there another way to specify a relative path? What am I getting wrong?

Answer 1

A simple way to fix this without using compass is to declare a font-path function before including bootstrap. Your sass should look like the following:

app.scss

// your bootstrap default overrides here

$icon-font-path: '../fonts/bootstrap/';

@function font-path($path) {
  @return $path;
}

@import 'bootstrap-sprockets';
@import 'bootstrap';

// your application styles here

Bit of a hack, and i'm not sure if anything else won't work with a setup like this (not using compass) but it appears to be working for me so far.
