Doesn't understand LESS nesting

[djboris88]

When in less file, nested styles shows as &.child while it should be #parent .something.
It renders it difficult to navigate, since I got many &:after and I cannot differ them. Is there a way around for this?

[Hirse]

I don't really use less, so I didn't pay much attention to it, but I am happy to improve it if I can.
Could you add an example less file and tell me what you expect to see in the outline?

[djboris88]

It would be great if you could add full support for less! I am currently working on some project, where I have to migrate template from old framework to a new one, and I have to migrate styles from 10 less files into 22 files, to categorize them and make it work. I often find myself lost in all those files and styles in so many places. I am certain that less outliner would do miracles for me.

Ok, here is the example.

[Hirse]

I have pushed a version to the branch less-indentation. Could you install the extension from GitHub and try it out?

[djboris88]

I tried it, it is much, much better now, thank you very much!

There is just one more thing, when there is more than one selector, like h1, h2, h3 { ... } it only shows the last one, in this example h3.

[Hirse]

Yes, I am aware of that limitation.
Currently I only check line by line, so this should only occur if the selector spans over several lines.
