Description

Fmt exposes combinators to devise Format pretty-printing functions.

Fmt depends only on the OCaml standard library. The optional Fmt_tty library that allows to setup formatters for terminal color output depends on the Unix library. The optional Fmt_cli library that provides command line support for Fmt depends on cmdliner.

Fmt is distributed under the ISC license.

Fmt — OCaml Format pretty-printer combinators

Fmt exposes combinators to devise Format pretty-printing functions.

Fmt depends only on the OCaml standard library. The optional Fmt_tty library that allows to setup formatters for terminal color output depends on the Unix library. The optional Fmt_cli library that provides command line support for Fmt depends on cmdliner.

Installation

Fmt can be installed with opam:

    opam install fmt
opam install base-unix cmdliner fmt # Install all optional libraries

If you don't use opam consult the opam file for build instructions.

Documentation

The documentation can be consulted online or via odig doc fmt.

Questions are welcome but better asked on the OCaml forum than on the issue tracker.
