How can you compile files in koala, adding new changes, but not completely updating the file? And is there such a possibility in gallp?

Question

Less

Let's say I added some styles to style.css.
But now I need to work on the style.less file.
In koala, if I turn on compilation, then all changes made only in the style.css file will disappear after I update style.less, where these changes were not.
How to actually avoid this?

That's not how it's done. If you are working with a preprocessor, then there is no need to complete the file. If you really need to write pure CSS, then create and include a separate file for this. The compiler will overwrite the entire file anyway.
