I'm editing a .re file within Vim. I haven't yet wired up refmt to
something like ALE for automatic formatting
on save. By the time I'm done with my changes, indentation is a mess.
I can still take advantage of refmt to clean up my file.
:!refmt --in-place %
Running that command in Vim will cause the current file to be formatted.
How does it work?
It shells-out to refmt which does all the heavy lifting. The --in-place
flag means that the target file will be re-written by the formatted result.
The % is a handy Vim shorthand for the path and name of the current file.
