问题:

While testing my web app, I'd like to be able to set the value of one of my LESS @variables using a simple dropdown. (To change the color scheme altogether).

I guess after setting the value, LESS has to reload/recompile the .less files with the new value?

Is there any simple way of accomplishing this? (I'm not running node.js)

The basic example would be something like: 

styles.less
@base-color = `window.baseColor()`

I think you're doing it in a bit too complicated way ;)

Here's what I propose:

  1. Set a class on your body tag:

    <body class='theme_default'></body>

  2. In your .less file define your themes:

    body.theme_default { base_color: #fff; }
body.theme_gray    { base_color: #ccc; }
etc..

  3. Using jQuery (or just plain JS) change the class of the body tag upon dropdown state change.

That's how I'd do it (and replace the dropdown with some nice widget ;) Cheers
