Hmap provides heterogeneous value maps for OCaml. These maps bind keys to values with arbitrary types. Keys witness the type of the value they are bound to which allows adding and looking up bindings in a type safe manner.

OCaml-SSL is a set of bindings for OpenSSL, a library for communicating through Transport Layer Security (TLS) encrypted connections.

Tsdl is an OCaml library providing thin bindings to the cross-platform SDL C library.

Lambda-Term is a cross-platform library for manipulating the terminal. It provides an abstraction for keys, mouse events, colors, as well as a set of widgets to write curses-like applications. The main objective of Lambda-Term is to provide a higher level functional interface to terminal manipulation than, for example, ncurses, by providing a native OCaml interface instead of bindings to a C library.

This ocaml library returns user XDG directories such as XDG_CONFIG_HOME, XDG_STATE_HOME.

This module provides a vi-like modal editing engine generator.

C header files shared between the various Jane Street packages.

This package provides string type based on [Bigarray], for use in I/O and C-bindings.

OCaml is written in OCaml. Its sources contain a pre-compiled bytecode version of ocamlc and ocamllex that are used to build the next version of the compiler. Camlboot implements a bootstrap for the OCaml compiler and provides a bootstrapped equivalent to these files.

It contains a compiler for a small subset of OCaml written in Guile Scheme, an interpreter for OCaml written in that subset and a manually-written lexer for OCaml. These elements eliminate the need for the binary bootstrap in OCaml and can effectively bootstrap OCaml 4.07.

This package produces a native ocamlc and a bytecode ocamllex.

This is the binding for SHA interface code in OCaml, offering the same interface as the MD5 digest included in the OCaml standard library. It currently provides SHA1, SHA256 and SHA512 hash functions.

Libraries for creating shared memory producer/consumer rings. The rings follow the Xen ABI and may be used to create or implement Xen virtual devices.

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 backports some of the new stdlib features to older compilers, such as the Stdlib module. This allows projects that require compatibility with older compiler to use these new features in their code.

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.

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.

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.

Output trace data to a file in Chrome's trace_event format. This format is compatible with chrome trace viewer chrome://tracing. This library offers no backwards compatibility guarantees.

The OCaml compiler has a bunch of intrinsics for Bigstrings, but they're not widely-known, sometimes misused, and so programs that use Bigstrings are slower than they have to be. And even if a library got that part right and exposed the intrinsics properly, the compiler doesn't have any fast blits between Bigstrings and other string-like types. bigstringaf provides these missing pieces.

An implementation inspired by Okasaki & Gill's paper 'Fast Mergeable Integer Maps.'

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.

Bisect_ppx helps you test thoroughly. It is a small preprocessor that inserts instrumentation at places in your code, such as if-then-else and match expressions. After you run tests, Bisect_ppx gives a nice HTML report showing which places were visited and which were missed.

Usage is simple - add package bisect_ppx when building tests, run your tests, then run the Bisect_ppx report tool on the generated visitation files.

Unix-specific extensions to some of the modules defined in core and core_kernel.

Unix-related dependencies for things like system calls and threads. Using these, it hooks the Async_kernel scheduler up to either epoll or select, depending on availability, and manages a thread pool that blocking system calls run in.

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