Loading multiple font-face with LESS

fonts.less

//** Relative path to files
@font-path: 'font/path/';

//** A default mixin to be used for fonts.
.fontface(@family, @filename-base, @weight, @style, @svgID){
  @font-face {
    font-family: '@{family}';
    src: url('@{font-path}@{filename-base}.eot');
    src: url('@{font-path}@{filename-base}.eot?#iefix') format('embedded-opentype'),
         url('@{font-path}@{filename-base}.woff2') format('woff2'),
         url('@{font-path}@{filename-base}.woff') format('woff'),
         url('@{font-path}@{filename-base}.ttf') format('truetype'),
         url('@{font-path}@{filename-base}.svg#@{svgID}') format('svg');
    font-weight: @weight;
    font-style: @style;
  }
}

//** Generating @font-face definition using above mixin and providing variables

//Regular
.fontface(Cool Font, coolfont-regular-webfont, normal, normal, cool_fontregular);

//Bold
.fontface(Cool Font, coolfont-bold-webfont, bold, normal, cool_fontbold);

// Add as many font-face definitions as you wish


//Output of this LESS file should be like this (This is only for example, do not copy lines bellow it is CSS output only, not LESS)
