Defines compile-time constants used in Jane Street libraries such as Base, Core, and Async. This package has an unstable interface; it is intended only to share configuration between different packages from Jane Street. Future updates may not be backward-compatible, and we do not recommend using this package directly.

Library to provide pure OCaml functions to manipulate real file (POSIX like) and filename.

This package provides a GLR parser generator for OCaml. It is able to generate self-extensible parsers (also called adaptive parsers) as well as extensible lexers for the parsers it produces.

Repository contents:

• client library, a merge of the Mirage and XCP ones

• server library

• server instance which runs under Unix with libxc

• server instance which runs on mirage.

The client and the server libraries have sets of unit-tests.

Unix-related dependencies for things like system calls and threads. Using these, it hooks the Async_kernel scheduler up to either epoll or select, depending on availability, and manages a thread pool that blocking system calls run in.

This package is a collection of ppx rewriters that generate hash functions from type exrpessions and definitions.

Cinaps is a trivial Metaprogramming tool using the OCaml toplevel. It is based on the same idea as expectation tests. The user writes some OCaml code inside special comments and cinaps makes sure that what follows is what is printed by the OCaml code.

The opam monorepo plugin provides a convenient interface to bridge the opam package manager with having a local copy of all the source code required to build a project using the dune build tool.

ocaml-mdx executes code blocks inside markdown files. There are (currently) two sub-commands, corresponding to two modes of operations: pre-processing (ocaml-mdx pp) and tests (ocaml-mdx test]).

The pre-processor mode allows mixing documentation and code, and to practice literate programming using markdown and OCaml.

The test mode ensures that shell scripts and OCaml fragments in the documentation always stays up-to-date.

ocaml-mdx is released as two binaries called ocaml-mdx and mdx which are the same, mdx being the deprecated name, kept for now for compatibility.

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 package provides utilities for building unitary testing of interactive program. You can match the question using a regular expression or a timeout.

Handle computation results and errors in an explicit and declarative manner, without resorting to exceptions. It defines combinators to operate on the result type available from OCaml 4.03 in the standard library.

This library implements the standard functions used by Dune.

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.

This package is part of Jane Street's Core library. Sexplib contains functionality for parsing and pretty-printing s-expressions.

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.

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

Tsdl is an OCaml library providing thin bindings to the cross-platform SDL C library.

This package generates S-expression conversion functions from type definitions.

This package provides a splittable PRNG functions like a PRNG that can be used as a stream of random values; it can also be split to produce a second, independent stream of random values.

This library implements a splittable pseudo-random number generator that sacrifices cryptographic-quality randomness in favor of performance.

Provides a single function to report the current time in nanoseconds since the start of the Unix epoch.

ppx_bap is the set of blessed ppx rewriters used in BAP projects. It fills the same role as ppx_base or ppx_jane (from which it is derived), but doesn't impose any style requirements and has only the minimal necessary set of rewriters.

Part of the Jane Street's PPX rewriters collection.

Define a standard set of libraries which may be expected on every compliant installation of OCaml and organize these libraries into a hierarchy of modules.
