The Core suite of libraries is an alternative to OCaml's standard library.

This module implements strict impure trie tree data structure for OCaml.

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

This package provides OCaml bindings to the Linux io_uring kernel IO interfaces.

Cstruct is a library and syntax extension to make it easier to access C-like structures directly from OCaml. It supports both reading and writing to these structures, and they are accessed via the Bigarray module.

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

This package provides an OCaml library for interacting with files in the TOML format. Specifically, it provides a parser, a serializer, and a pretty printer.

This package contains code that is shared between various dune packages. However, it is not meant for public consumption and provides no stability guarantee.

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.

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 module provides a vi-like modal editing engine generator.

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

Ppx_derivers is a tiny package whose sole purpose is to allow ppx_deriving and ppx_type_conv to inter-operate gracefully when linked as part of the same ocaml-migrate-parsetree driver.

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.

This library helps embed location information inside executables and libraries

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.

Uses a Mirage CLOCK to write timestamped log messages. It can also log only important messages to the console, while writing all received messages to a ring buffer which is displayed if an exception occurs. If tracing is enabled (via mirage-profile), it also writes each log message to the trace buffer.

Parses and constructs RFC compliant domain names. The invariants on the length of domain names are preserved throughout the module.

IO pages are page-aligned, and wrapped in the Cstruct library to avoid copying the data contained within the page.

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.

ocaml-mdx executes code blocks inside markdown files. There are (currently) two sub-commands, corresponding to two modes of operations: pre-processing (ocaml-mdx pp) and tests (ocaml-mdx test]).

The pre-processor mode allows mixing documentation and code, and to practice literate programming using markdown and OCaml.

The test mode ensures that shell scripts and OCaml fragments in the documentation always stays up-to-date.

ocaml-mdx is released as two binaries called ocaml-mdx and mdx which are the same, mdx being the deprecated name, kept for now for compatibility.

Gen implements iterators of OCaml, that are both restartable and consumable.

Bindings providing OCaml support for the seminal Fast Fourier Transform library FFTW.

OCamlify creates OCaml source code by including whole files into OCaml string or string list. The code generated can be compiled as a standard OCaml file. It allows embedding external resources as OCaml code.
