This library parses ocaml compiler output and returns it as ocaml values. This library offers no backwards compatibility guarantees.

Ocaml-cairo2 is a binding to Cairo, a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System, Quartz, Win32, image buffers, PostScript, PDF, and SVG file output.

This package includes only the ocp-index library and command-line tool.

This package provides helpers with various constructions that involve memoization and recursion.

Piqilib is the common library used by the piqi command-line tool and piqi-ocaml.

This package provides an effect-based IO API for multicore OCaml with fibers.

Dune-configurator is a small library that helps writing OCaml scripts that test features available on the system, in order to generate config.h files for instance. Among other things, dune-configurator allows one to:

• test if a C program compiles

• query pkg-config

• import #define from OCaml header files

• generate config.h file

Uses the new result type defined in OCaml >= 4.03 while staying compatible with older version of OCaml should use the Result module defined in this library.

This module provides an abstract engine for text edition. It can be used to write text editors, edition widgets, readlines, and more. The module Zed uses Camomile to fully support the Unicode specification, and implements an UTF-8 encoded string type with validation, and a rope datastructure to achieve efficient operations on large Unicode buffers. Zed also features a regular expression search on ropes. To support efficient text edition capabilities, Zed provides macro recording and cursor management facilities.

Alcotest exposes simple interface to perform unit tests. It exposes a simple TESTABLE module type, a check function to assert test predicates and a run function to perform a list of unit -> unit test callbacks. Alcotest provides a quiet and colorful output where only faulty runs are fully displayed at the end of the run (with the full logs ready to inspect), with a simple (yet expressive) query language to select the tests to run.

Base is a complete and portable alternative to the OCaml standard library. It provides all standard functionalities one would expect from a language standard library. It uses consistent conventions across all of its module.

Base aims to be usable in any context. As a result system dependent features such as I/O are not offered by Base. They are instead provided by companion libraries such as ocaml-stdio.

This package allows parsing of dates that follow the ISO 8601 and RFC 3339 formats in OCaml.

This library helps embed location information inside executables and libraries

ppx-fixed-literal is a ppx rewriter that rewrites fixed point literal of the form 1.0v to conversion functions currently in scope.

This package allows you to produce, from a set of bibliography files in BibTeX format, a bibliography in HTML format.

This package provides a non-blocking encoder/decoder of Quoted-Printable according to RFC2045 and RFC2047 (about encoded-word). Useful to translate contents of emails.

This package provides a splittable PRNG functions like a PRNG that can be used as a stream of random values; it can also be split to produce a second, independent stream of random values.

This library implements a splittable pseudo-random number generator that sacrifices cryptographic-quality randomness in favor of performance.

Down is an unintrusive user experience upgrade for the ocaml toplevel (REPL).

Simply load the zero dependency down library in the ocaml toplevel and you get line edition, history, session support and identifier completion and documentation with ocp-index.

Add this to your ~/.ocamlinit:

#use "down.top"

You may also need to add this to your ~/.ocamlinit and declare the environment variable OCAML_TOPLEVEL_PATH:

let () =
  try Topdirs.dir_directory (Sys.getenv "OCAML_TOPLEVEL_PATH")
  with Not_found -> ()

OR

let () = String.split_on_char ':' (Sys.getenv "OCAMLPATH")
         |> List.filter (fun x -> Filename.check_suffix x "/site-lib")
         |> List.map (fun x -> x ^ "/toplevel")
         (* remove the line below if you don't want to see the text
            every time you start the toplevel *)
         |> List.map (fun x -> Printf.printf "adding directory %s\n" x; x)
         |> List.iter Topdirs.dir_directory;;

ocaml-dot-merlin-reader is an external reader for ocaml-merlin configurations.

Cmdliner is a module for the declarative definition of command line interfaces. It provides a simple and compositional mechanism to convert command line arguments to OCaml values and pass them to your functions. The module automatically handles syntax errors, help messages and UNIX man page generation. It supports programs with single or multiple commands and respects most of the POSIX and GNU conventions.

Ocb-stubblr is about ten lines of code that you need to repeat over, over, over and over again if you are using ocamlbuild to build OCaml projects that contain C stubs.

Pure OCaml regular expressions with:

1. Perl-style regular expressions (module Re_perl)

2. Posix extended regular expressions (module Re_posix)

3. Emacs-style regular expressions (module Re_emacs)

4. Shell-style file globbing (module Re_glob)

5. Compatibility layer for OCaml's built-in Str module (module Re_str)

This OCaml library provides an implementation of a mutable doubly-linked list with Lwt iterators.

Fpath is an OCaml module for handling file system paths with POSIX or Windows conventions. Fpath processes paths without accessing the file system and is independent from any system library.
