Extensions to printf-style format-strings for user-defined string conversion.

base-quickcheck provides randomized testing in the style of Haskell's Quickcheck library, with support for built-in types as well as types provided by Base.

QuickCheck inspired property-based testing for OCaml. This module checks invariants (properties of some types) over randomly generated instances of the type. It provides combinators for generating instances and printing them.

Stdio implements simple input/output functionalities for OCaml. It re-exports the input/output functions of the OCaml standard libraries using a more consistent API.

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.

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

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

A ppx rewriter that rewrites simple match statements with an if then else expression.

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

This package provides an effect-based IO API for multicore OCaml with fibers.

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

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This library is an alternative to pycaml which is no longer maintained.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.

Monolith offers facilities for testing an OCaml library (for instance, a data structure implementation) by comparing it against a reference implementation. It can be used to perform either random testing or fuzz testing by using the afl-fuzz tool.

This OCaml library offers a set of combinators for building so-called documents as well as an efficient engine for converting documents to a textual, fixed-width format. The engine takes care of indentation and line breaks, while respecting the constraints imposed by the structure of the document and by the text width.

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.

Ocaml-junit is a package for the creation of JUnit XML reports. It provides a typed API to produce valid reports. They are supposed to be accepted by Jenkins.

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.

Uucp is an OCaml library providing efficient access to a selection of character properties of the Unicode character database.

Octavius is a library to parse the `ocamldoc` comment syntax.

This package contains assert-like extension nodes that raise useful errors on failure.

Client-side URL transfer library, supporting HTTP and a multitude of other network protocols (FTP/SMTP/RTSP/etc).

Generate modules from OCaml source files.

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

This package adds S-exp support to ocaml-uri.
