This package is an OCaml library to parse and generate the YAML file format. It is intended to be interoperable with the Ezjsonm JSON handling library, if the simple common subset of Yaml is used. Anchors and other advanced Yaml features are not implemented in the JSON compatibility layer.

This package installs a ppx-jane executable, which is a ppx driver including all standard Jane Street ppx rewriters.

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.

C header files shared between the various Jane Street packages.

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.

Ezjsonm provides more convenient (but far less flexible) input and output functions that go to and from [string] values than jsonm. This avoids the need to write signal code, which is useful for quick scripts that manipulate JSON.

OCaml-Num contains the legacy Num library for arbitrary-precision integer and rational arithmetic that used to be part of the OCaml core distribution.

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.

Ppx_sexp_message aims to ease the creation of s-expressions in OCaml. This is mainly motivated by writing error and debugging messages, where one needs to construct a s-expression based on various element of the context such as function arguments.

Bindlib is a library allowing the manipulation of data structures with bound variables. It is particularly useful when writing ASTs for programming languages, but also for manipulating terms of the λ-calculus or quantified formulas.

This library converts between parsetrees of different OCaml versions. For each version, there is a snapshot of the parsetree and conversion functions to the next and/or previous version.

Syntax extension that makes [failwiths] always include a position.

Contains Async's core data structures, like Deferred. Async_kernel is portable, and so can be used in JavaScript using Async_js.

This package is a line-reading library for OCaml that aims to replace readline.

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 to connect and control a running dune instance.

This package backports new language features such as let+ to older OCaml compilers.

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

This project provides a Mmap.map_file function for mapping files in memory. This function is the same as the Unix.map_file function added in OCaml >= 4.06.

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

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

Eio_main selects an appropriate backend (e.g. eio_linux or eio_luv), depending on your platform.

Topkg is a packager for distributing OCaml software. It provides an API to describe the files a package installs in a given build configuration and to specify information about the package's distribution, creation and publication procedures.

Uucd is an OCaml module to decode the data of the Unicode character database from its XML representation. It provides high-level (but not necessarily efficient) access to the data so that efficient representations can be extracted.
