How to set tab indents in Koala, and what are *.css.map files created for?

Question

css

I decided to find out what kind of beast this is, this sass . I
took Koala as a compiler for windows (so that there would be less fuss and extra files, but with wider functionality (Sass Build in sublime is not particularly configured)
And there were questions: how to set indents, what in css files were tabs, not two spaces, and why are *.css.map files created?
And is there an option built right into sublim text 3, with parameter settings and autocompilation on save?

Answer 1

And the questions arose: how to set indents, what were tabs in css, and not two spaces, and why are *.css.map files created?

What for? You will be working with sass files. And css generally needs to be compressed, removing all unnecessary characters from them. It should look like this
. And maps are needed so that in the browser you can see the location of the style in the source scss file, and not in css

Answer 2

php.net/manual/en/function.array-keys.php

$keys = array_keys($test);
var_export($keys);

And don't even ask why.

Well then, don't be offended if it turns out that I didn't guess, and array_keys() doesn't suit you. There are other ways, but I'm not going to copy the entire manual here .
