This is a formatter for OCaml that only format the inside of a line. It does not change indentation or add line breaks. It is based on the OCaml lexer and decides which lexing token should be separated by a space and which should not.

It is meant to be used alongside ocp-indent.

Usage:

For output on stdout:

dune exec format-line -- input.ml

For output in a file:

dune exec bin/main.exe input.ml -o output

For formatting the file inline:

dune exec bin/main.exe input.ml -i
