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

Spawn is a small library exposing only one functionality: spawning sub-process.

It has three main goals:

• provide missing features of Unix.create_process such as providing a working directory,

• provide better errors when a system call fails in the sub-process. For instance if a command is not found, you get a proper Unix.Unix_error exception,

• improve performances by using vfork when available. It is often claimed that nowadays fork is as fast as vfork, however in practice fork takes time proportional to the process memory while vfork is constant time. In application using a lot of memory, vfork can be thousands of times faster than fork.

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.

Optimised functions to read and write int16/32/64 from strings and bigarrays, based on new primitives added in version 4.01. It works on strings, bytes and bigstring (Bigarrys of chars), and provides submodules for big- and little-endian, with their unsafe counter-parts.

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

Ppx_fields_conv is a ppx rewriter that can be used to define first class values representing record fields, and additional routines, to get and set record fields, iterate and fold over all fields of a record and create new record values.

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

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.

UTop is an improved toplevel for OCaml. It can run in a terminal or in Emacs. It supports line editing, history, real-time and context sensitive completion, colors, and more.

Ctypes is a library for binding to C libraries using pure OCaml. The primary aim is to make writing C extensions as straightforward as possible. The core of ctypes is a set of combinators for describing the structure of C types -- numeric types, arrays, pointers, structs, unions and functions. You can use these combinators to describe the types of the functions that you want to call, then bind directly to those functions -- all without writing or generating any C!

Ocb-stubblr is about ten lines of code that you need to repeat over, over, over and over again if you are using ocamlbuild to build OCaml projects that contain C stubs.

CamlPDF is an OCaml library that provides functionality for reading, writing, and modifying PDF files. It serves as the foundation for the cpdf command-line tool and various API bindings.

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

Generation of binary serialization and deserialization functions from type definitions.

This package contains a compatibility library for Stdlib.Bigarray in OCaml.

opam-installer is a tool for installing OCaml packages based on .install files defined by the OPAM package manager. It is useful for installing OCaml packages without requiring the entirety of OPAM.

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

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

This package provides two union-find data structure implementations for OCaml. Both implementations are based on disjoint sets forests, with path compression and linking-by-rank, so as to guarantee good asymptotic complexity: every operation requires a quasi-constant number of accesses to the store.

This library implements structured concurrency for ocaml. It offers no backwards compatibility guarantees.

Comma separated values (CSV) is a simple tabular format supported by all major spreadsheets. This library implements pure OCaml functions to read and write files in this format as well as some convenience functions to manipulate such data.

Ppx_yojson_conv_lib is the runtime library used by ppx_yojson_conv, a ppx rewriter that can be used to convert ocaml types to a Yojson.Safe value.

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.

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.
