Once you visit a .lass file, it will automatically start in the LASS major-mode, which is a derived-mode from COMMON-LISP-MODE. Whenever you save, it will automatically try to compile the lass file to its CSS equivalent. If slime is connected, it will try to quickload LASS and evaluate GENERATE. If slime is not connected, it instead executes a shell command. In order for that to work, the lass binary must be in your path.
If your operating system is not directly supported with a binary, you can build it yourself using a build tool like Buildapp, the ASDF system BINARY-LASS and the entry-point BINARY-LASS:CMD-WRAPPER.
ASDF Integration
+ +If you want to compile LASS files to CSS in your systems, you can now (v0.4+) do this via a lass-file component type, and :defsystem-depends-on-ing LASS.
(asdf:defsystem my-system
+ :defsystem-depends-on (:lass)
+ :components ((:lass-file "test-file")))You can also specify an :output argument to a lass-file to specify what the target css file should be.
