This package is a ppx extension for easier implementation of conversion functions between almost identical types.

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.

Pcre-ocaml offers library functions for string pattern matching and substitution, similar to the functionality offered by the Perl language.

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.

Ppx_deriving provides common infrastructure for generating code based on type definitions, and a set of useful plugins for common tasks.

Small implementation of a simple argv parser.

Uses the new result type defined in OCaml >= 4.03 while staying compatible with older version of OCaml should use the Result module defined in this library.

Yojson is an optimized parsing and printing library for the JSON format. It addresses a few shortcomings of json-wheel including 2x speedup, polymorphic variants and optional syntax for tuples and variants. ydump is a pretty printing command-line program provided with the yojson package. The program atdgen can be used to derive OCaml-JSON serializers and deserializers from type definitions.

A ppx rewriter for monadic and applicative let bindings, match expressions, and if expressions.

Unit testing framework for OCaml. It is similar to JUnit and other XUnit testing frameworks.

This library is a compatibility module for the Either module defined in OCaml 4.12.0.

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.

Utilities for working with terminal output, such as color printing.

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

The subset of textutils using only core_kernel and working in javascript.

This library provides generic parsers for parsing S-expressions from strings or other medium.

The library is focused on performances but still provide full generic parsers that can be used with strings, bigstrings, lexing buffers, character streams or any other sources effortlessly.

It provides three different class of parsers:

• the normal parsers, producing [Sexp.t] or [Sexp.t list] values

• the parsers with positions, building compact position sequences so that one can recover original positions in order to report properly located errors at little cost

• the Concrete Syntax Tree parsers, produce values of type Parsexp.Cst.t which record the concrete layout of the s-expression syntax, including comments

This library is portable and doesn't provide IO functions. To read s-expressions from files or other external sources, you should use parsexp_io.

This package provides ppx_sexp_message-like extension nodes for lazily rendering log messages.

Crowbar is a library for testing code, combining QuickCheck-style property-based testing and the magical bug-finding powers of afl-fuzz.

Bos provides support for basic and robust interaction with the operating system in OCaml. It has functions to access the process environment, parse command line arguments, interact with the file system and run command line programs.

Uses the new result type defined in OCaml >= 4.03 while staying compatible with older version of OCaml should use the Result module defined in this library.

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.

Expect-test is a framework for writing tests in OCaml, similar to Cram. Expect-tests mimics the existing inline tests framework with the let%expect_test construct. The body of an expect-test can contain output-generating code, interleaved with %expect extension expressions to denote the expected output.

Cohttp is an OCaml library for creating HTTP daemons. It has a portable HTTP parser, and implementations using various asynchronous programming libraries.
