Angstrom is a parser-combinator library that makes it easy to write efficient, expressive, and reusable parsers suitable for high-performance applications. It exposes monadic and applicative interfaces for composition, and supports incremental input through buffered and unbuffered interfaces. Both interfaces give the user total control over the blocking behavior of their application, with the unbuffered interface enabling zero-copy IO. Parsers are backtracking by default and support unbounded lookahead.

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.

Traditional implementation of priority queues using a binary heap encoded in a resizable array.

LablGtk is an OCaml interface to GTK+ 1.2, 2.x and 3.x. It provides a strongly-typed object-oriented interface that is compatible with the dynamic typing of GTK+. Most widgets and methods are available. LablGtk also provides bindings to gdk-pixbuf, the GLArea widget (in combination with LablGL), gnomecanvas, gnomeui, gtksourceview, gtkspell, libglade (and it can generate OCaml code from .glade files), libpanel, librsvg and quartz.

This library provides Functional Priority Search Queues for OCaml. Typical applications are searches, schedulers and caches.

This package provides a deprecated logging component for ocaml lwt.

Dune is a build system for OCaml. It provides a consistent experience and takes care of the low-level details of OCaml compilation. Descriptions of projects, libraries and executables are provided in dune files following an s-expression syntax.

This package contains assert-like extension nodes that raise useful errors on failure.

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 OCaml library provides two new integer types, Optint.t and Int63.t, which guarantee efficient representation on 64-bit architectures and provide a best-effort boxed representation on 32-bit architectures.

This package provides ppx_sexp_message-like extension nodes for lazily rendering log messages.

React is an OCaml module for functional reactive programming (FRP). It provides support to program with time varying values: declarative events and signals. React doesn't define any primitive event or signal, it lets the client chooses the concrete timeline.

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

FrontC is an OCAML library providing a C parser and lexer. The result is a syntactic tree easy to process with usual OCAML tree management. It provides support for ANSI C syntax, old-C K&R style syntax and the standard GNU CC attributes. It provides also a C pretty printer as an example of use.

Uuidm is an OCaml module implementing 128 bits universally unique identifiers (UUIDs) version 3, 5 (named based with MD5, SHA-1 hashing) and 4 (random based) according to RFC 4122.

afl-fuzz normally works by repeatedly forking the program being tested. Using this package, you can run afl-fuzz in ``persistent mode'', which avoids repeated forking and is much faster.

IP address types with serialization, supporting a wide range of RFCs.

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

A ppx rewriter for monadic and applicative let bindings, match expressions, and if expressions.

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.

OCamlgraph is a generic graph library for OCaml.

Syntax extension to define first class values representing record fields, to get and set record fields, iterate and fold over all fields of a record and create new record values.

Library for asynchronous programming, i.e., programming where some part of the program must wait for things that happen at times determined by some external entity (like a human or another program).

Client-side URL transfer library, supporting HTTP and a multitude of other network protocols (FTP/SMTP/RTSP/etc).
