Library that allows OCaml programs to interact with Python modules and objects. The library also provides low-level bindings to the Python C API.

This library is an alternative to pycaml which is no longer maintained. The Pycaml module provides a signature close to pycaml, to ease migration of code to this library.

Ppx_optcomp stands for Optional Compilation. It is a tool used to handle optional compilations of pieces of code depending of the word size, the version of the compiler, ...

DSL to describe a set of modules and functors, their types and how to apply them in order to produce a complete application. The main use case is mirage.

Dose3 is a framework made of several OCaml libraries for managing distribution packages and their dependencies. Though not tied to any particular distribution, dose3 constitutes a pool of libraries which enable analyzing packages coming from various distributions. Besides basic functionalities for querying and setting package properties, dose3 also implements algorithms for solving more complex problems such as monitoring package evolutions, correct and complete dependency resolution and repository-wide uninstallability checks.

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 adds S-exp support to ocaml-uri.

Library for pretty-printing s-expressions, using better indentation rules than the default pretty printer in Sexplib.

Similar to make utilities you may have used, but it features many additional enhancements, including:

1. Support for projects spanning several directories or directory hierarchies.

2. Fast, reliable, automated, scriptable dependency analysis using MD5 digests, with full support for incremental builds.

3. Dependency analysis takes the command lines into account — whenever the command line used to build a target changes, the target is considered out-of-date.

4. Fully scriptable, includes a library that providing support for standard tasks in C, C++, OCaml, and LaTeX projects, or a mixture thereof.

OUnit2 is a unit testing framework for OCaml. It is similar to JUnit and other XUnit testing frameworks.

This package provides the MirageOS `OS` library for Unix targets, which handles the main loop and timers.

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.

Defines the signature for time-related operations for MirageOS.

This is the binding for SHA interface code in OCaml, offering the same interface as the MD5 digest included in the OCaml standard library. It currently provides SHA1, SHA256 and SHA512 hash functions.

Cppo is an equivalent of the C preprocessor for OCaml programs. It allows the definition of simple macros and file inclusion. Cppo is:

1. more OCaml-friendly than cpp

2. easy to learn without consulting a manual

3. reasonably fast

4. simple to install and to maintain.

Helper functions for writing expect tests.

BEnchmark for a CHAMEL/camel/caml which is agnostic to the system. It's a micro-benchmark tool for OCaml which lets the user to re-analyzes and prints samples.

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

Ocp-indent is based on an approximate, tolerant OCaml parser and a simple stack machine. Presets and configuration options are available, with the possibility to set them project-wide. It supports the most common syntax extensions, and it is extensible for others.

This package includes:

• An indentor program, callable from the command-line or from within editors,

• Bindings for popular editors,

• A library that can be directly used by editor writers, or just for fault-tolerant and approximate parsing.

This package provides the lablgtk interface to the GTK+ gtksourceview library.

Hmap provides heterogeneous value maps for OCaml. These maps bind keys to values with arbitrary types. Keys witness the type of the value they are bound to which allows adding and looking up bindings in a type safe manner.

Access monotonic wall-clock time. It measures time spans without being subject to operating system calendar time adjustments.

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.

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.

Eio_luv provides a cross-platform backend for Ocaml Eio's APIs using luv (libuv)
