Options changing the tool's behavior

type t = {
  1. fmt_opts : fmt_opts;
  2. opr_opts : opr_opts;
}
val default : t
type input = {
  1. kind : Syntax.t;
  2. name : Ocamlformat_stdlib.string;
  3. file : file;
  4. conf : t;
}
type action =
  1. | In_out of input * Ocamlformat_stdlib.string Ocamlformat_stdlib.option
    (*

    Format input file (or - for stdin) of given kind to output file, or stdout if None.

    *)
  2. | Inplace of input Ocamlformat_stdlib.list
    (*

    Format in-place, overwriting input file(s).

    *)
  3. | Check of input Ocamlformat_stdlib.list
    (*

    Check whether the input files already are formatted.

    *)
  4. | Print_config of t
    (*

    Print the configuration and exit.

    *)
  5. | Numeric of input

Formatting action: input type and source, and output destination.

update ?quiet c a updates configuration c after reading attribute a. quiet is false by default.
