ocaml pretty printer (code formatter)

问题

I am looking for a code formatter or pretty printer for ocaml. Something like gofmt for the go programming language. It should preferably preserve comments.

I am correcting hand-ins and some of the code is formatted in a way that makes it very hard to read.

回答1:

if you don't care about comments, you can use camlp4:

camlp4 <file> -parser o -printer o > <new-file>

Or you can use external indenter tools, as ocp-indent.
