base-quickcheck provides randomized testing in the style of Haskell's Quickcheck library, with support for built-in types as well as types provided by Base.

OCaml is a general purpose industrial-strength programming language with an emphasis on expressiveness and safety. Developed for more than 20 years at Inria it benefits from one of the most advanced type systems and supports functional, imperative and object-oriented styles of programming.

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

This module implements purely in OCaml a character width function that follows the prototype of POSIX's wcwidth.

Syntax extension for writing in-line benchmarks in ocaml code.

This package contains deriving conversion functions to and from yaml for OCaml types.

Provides easy access to compressed files in ZIP, GZIP and JAR format. It provides functions for reading from and writing to compressed files in these formats.

This package is an OCaml library to parse and generate the YAML file format. It is intended to be interoperable with the Ezjsonm JSON handling library, if the simple common subset of Yaml is used. Anchors and other advanced Yaml features are not implemented in the JSON compatibility layer.

A ppx rewriter that rewrites simple match statements with an if then else expression.

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.

This package adds S-exp support to ocaml-uri.

The uchar package provides a compatibility library for the `Uchar` module introduced in OCaml 4.03.

Spawn is a small library exposing only one functionality: spawning sub-process.

It has three main goals:

• provide missing features of Unix.create_process such as providing a working directory,

• provide better errors when a system call fails in the sub-process. For instance if a command is not found, you get a proper Unix.Unix_error exception,

• improve performances by using vfork when available. It is often claimed that nowadays fork is as fast as vfork, however in practice fork takes time proportional to the process memory while vfork is constant time. In application using a lot of memory, vfork can be thousands of times faster than fork.

OCamlFormat is a tool to automatically format OCaml code in a uniform style.

Cohttp is an OCaml library for creating HTTP daemons. It has a portable HTTP parser, and implementations using various asynchronous programming libraries.

This library offers a lightweight way for applications protocols to version themselves. The more protocols that add themselves to Known_protocol, the nicer error messages we will get when connecting to a service while using the wrong protocol.

Ppx_tools provides tools for authors of ppx rewriters and other syntactic tools.

Library operating system that constructs unikernels for secure, high-performance network applications across a variety of cloud computing and mobile platforms. Code can be developed on a normal OS and then compiled into a fully-standalone, specialised unikernel.

This package provides the lablgtk interface to the GTK+ gtksourceview library.

Piqi is a multi-format data serialization system for OCaml. It provides a uniform interface for serializing OCaml data structures to JSON, XML and Protocol Buffers formats.

Uucp is an OCaml library providing efficient access to a selection of character properties of the Unicode character database.

Implements arithmetic and logical operations over arbitrary-precision integers. It uses GMP to efficiently implement arithmetic over big integers. Small integers are represented as Caml unboxed integers, for speed and space economy.

This library provides an alternative to the Format module of the OCaml standard library. Pp uses the same concepts of boxes and break hints, and the final rendering is done to formatter from the Format module. However it defines its own algebra which some might find easier to work with and reason about.

This package provides a library for parsing the contents of OCaml documentation comments, formatted using Odoc syntax, an extension of the language understood by ocamldoc.
