"Major mode for editing Ebitengine Kage shader files.
This mode provides all the features go-mode provides, since kage files
are go compatible.
It also supports the use of gofmt -s. If you want to use it, add this
to your config:
\(add-hook 'before-save-hook #'kage-gofmt-before-save)"
(run-hooks 'kage-mode-hook))
;; we need to have our own call to gofmt, because the one in go-mode
;; only works with *.go files, but we use the original call to it anyway
