compile stylus sheets to a single file

Question

I am trying to write a watch script for my app. I have a stylus sheet for each feature of my app and I'd like to compile them into a single one.

stylus -u nib src/*/*/**.styl -o out/css/ --include-css -w

But this brings as many files as there are features. Is there a way to ensure that each newly compiled css file is appended to my out/css/main.css file rather than written as a new out/css/feature.css file?

Many thanks

Answer 1

You can import all the features in one file (main.styl) and watch only it (stylus -w main.styl), isn't it? Any changes to these files will be detected by Stylus and main.styl file will be recompiled as well. There is a reason why you don't do it this way?
