use source.cue to generate result json programmatically
if you are to just work on ../src, just the produced keybab.json is enough so you could skip anything below
$ make keybab.json
These are optional steps to make your debugging source.cue easier.
$ make develop # (or just `make`) to keep building `keybab.json` watching changes of `source.cue`
$ make preview # to see the result of `keybab.json` with a pager
# unfortunately I haven't found a way for less to refresh when file changes
# but you can type R to refresh manually when less is running
$ make follow # to see the result of `keybab.json` watching changes of itself
keybab.json is intended to be used from ../src and being tracked via git alongside source.cue.
