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 module provides an abstract engine for text edition. It can be used to write text editors, edition widgets, readlines, and more. The module Zed uses Camomile to fully support the Unicode specification, and implements an UTF-8 encoded string type with validation, and a rope datastructure to achieve efficient operations on large Unicode buffers. Zed also features a regular expression search on ropes. To support efficient text edition capabilities, Zed provides macro recording and cursor management facilities.

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

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.

Library for passing boot parameters from Solo5 to MirageOS.

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.

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.

HeVeA is a LaTeX to HTML translator that generates modern HTML 5. It is written in Objective Caml.

Typerep is a library for runtime types.

Provides an OCaml interface to operations that have dedicated hardware instructions on some micro-architectures, with default implementations using C stubs for all targets.

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

Lwt provides typed, composable cooperative threads. These make it easy to run normally-blocking I/O operations concurrently in a single process. Also, in many cases, Lwt threads can interact without the need for locks or other synchronization primitives.

Ppx_base is the set of ppx rewriters used for Base.

Note that Base doesn't need ppx to build, it is only used as a verification tool.

Digestif is an OCaml library that provides implementations of hash algorithms. Implemented hash algorithms include MD5, SHA1, SHA224, SHA256, SHA384, SHA512, Blake2b, Blake2s and RIPEMD160.

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

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

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

This library implements portable support for an operating system timesource that is compatible with the MirageOS library interfaces. It implements an MCLOCK module that represents a monotonic timesource since an arbitrary point, and PCLOCK which counts time since the Unix epoch.

This package allows you to produce, from a set of bibliography files in BibTeX format, a bibliography in HTML format.

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

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

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.

Timezone handles parsing timezone data and create Timezone.t that can later be used to manipulate time in core_kernel or core.
