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

This package is a no-op ppx rewriter. It is used as a lint tool to enforce some coding conventions across all Jane Street packages.

This package provides a parser of email address according RFC822, RFC2822, RFC5321 and RFC6532. It handles UTF-8 email addresses and encoded-word according RFC2047.

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.

The "findlib" library provides a scheme to manage reusable software components (packages), and includes tools that support this scheme. Packages are collections of OCaml modules for which metainformation can be stored. The packages are kept in the file system hierarchy, but with strict directory structure. The library contains functions to look the directory up that stores a package, to query metainformation about a package, and to retrieve dependency information about multiple packages. There is also a tool that allows the user to enter queries on the command-line. In order to simplify compilation and linkage, there are new frontends of the various OCaml compilers that can directly deal with packages.

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

Compatibility module for OCaml standard library allowing programs to use some recent additions to the standard library while preserving the ability to be compiled on former versions of OCaml.

QuickCheck inspired property-based testing for OCaml. This module checks invariants (properties of some types) over randomly generated instances of the type. It provides combinators for generating instances and printing them.

This library provides facilities to parse version numbers of the OCaml compiler, and enumerates the various official OCaml releases and configuration variants.

Easy-format is a high-level and functional interface to the Format module of the OCaml standard library.

Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. It is specified in RFC 4648.

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

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.

This package provides a GLR parser generator for OCaml. It is able to generate self-extensible parsers (also called adaptive parsers) as well as extensible lexers for the parsers it produces.

This package is a compatibility package for OCaml's standard iterator type starting from 4.07.

Typerep is a library for runtime types.

Merlin is an editor service that provides modern IDE features for OCaml. Emacs and Vim support is provided out-of-the-box. External contributors added support for Visual Studio Code, Sublime Text and Atom.

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.

OASIS is a tool to integrate a configure, build and install system in your OCaml projects. It helps to create standard entry points in your build system and allows external tools to analyse your project easily.

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.

The graphics library provides a set of portable drawing primitives. Drawing takes place in a separate window that is created when Graphics.open_graph is called. This library used to be distributed with OCaml up to OCaml 4.08.

Adds Erlang-style bitstrings and matching over bitstrings as a syntax extension and library for OCaml. You can use this module to both parse and generate binary formats, files and protocols. Bitstring handling is added as primitives to the language, making it exceptionally simple to use and very powerful.

ppx-sexp-value is a ppx rewriter that simplifies building s-expressions from ocaml values.

This package provides utilities for building unitary testing of interactive program. You can match the question using a regular expression or a timeout.
