I do like this less-autocompile package for Atom. But I don't like Atom too much. I wanted that plugin for Sublime Text 3. So I've created my own very first plugin for ST3 inspired by @lohek

Warning! My plugin has not been tested well and I can't recommend you to use it till I finish it. I'll remove this warning once it is done. I've tested in on macOS only for now.

There is no magic, the plugin uses node's lessc to do the job. So it depends on some packages installed globally.

npm install -g less less-plugin-clean-css

I didn't add my plugin to Sublime Packages so there is only a manual way to install. But this is quite easy to do.

You need to download the plugin and put the folder LessAutocompile to Packages folder of your Sublime Text 3. The Packages folder can be found:

• ~/Library/Application Support/Sublime Text 3/Packages (macOS)
• ~/config/sublime-text-3/Packages/ (Linux) Note It can be different, depends on the way you've installed Sublime Text 3

Add the parameters on the first lines of the LESS file.

out (string):  path of CSS file to create
sourcemap (bool): create sourcemap file
compress (bool): compress CSS file
main (string): path to your main LESS file to be compiled

less/styles.less

// out: ../css/styles.css
// sourcemap: true
// compress: true

@import "my/components/select.less";

less/my/components/select.less

// main: ../../styles.less

.select {
  height: 100px;
  width: 100px;
}

The plugin is being triggered every time .less file is saved.
