Digestif is an OCaml library that provides implementations of hash algorithms. Implemented hash algorithms include MD5, SHA1, SHA224, SHA256, SHA384, SHA512, Blake2b, Blake2s and RIPEMD160.

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.

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.

Part of Jane Street's Core library The Core suite of libraries is an industrial strength alternative to OCaml's standard library that was developed by Jane Street, the largest industrial user of OCaml.

The ocaml-integers library provides a number of 8-, 16-, 32- and 64-bit signed and unsigned integer types, together with aliases such as long and size_t whose sizes depend on the host platform.

This package provides a duration is represented in nanoseconds as an unsigned 64 bit integer. This has a range of up to 584 years. Functions provided check the input and raise on negative or out of bound input.

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.

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.

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.

Camomile is a Unicode library for OCaml. Camomile provides Unicode character type, UTF-8, UTF-16, UTF-32 strings, conversion to/from about 200 encodings, collation and locale-sensitive case mappings, and more. The library is currently designed for Unicode Standard 3.2.

This package contains an syntax extension to indicate that the code is on the cold path and should be kept out of the way to avoid polluting the instruction cache on the hot path. See also https://github.com/ocaml/ocaml/issues/8563.

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.

This library contains functionality for reading and writing OCaml-values in a type-safe binary protocol. It is extremely efficient, typically supporting type-safe marshalling and unmarshalling of even highly structured values at speeds sufficient to saturate a gigabit connection. The protocol is also heavily optimized for size, making it ideal for long-term storage of large amounts of data.

Cmdliner is a module for the declarative definition of command line interfaces. It provides a simple and compositional mechanism to convert command line arguments to OCaml values and pass them to your functions. The module automatically handles syntax errors, help messages and UNIX man page generation. It supports programs with single or multiple commands and respects most of the POSIX and GNU conventions.

Angstrom is a parser-combinator library that makes it easy to write efficient, expressive, and reusable parsers suitable for high-performance applications. It exposes monadic and applicative interfaces for composition, and supports incremental input through buffered and unbuffered interfaces. Both interfaces give the user total control over the blocking behavior of their application, with the unbuffered interface enabling zero-copy IO. Parsers are backtracking by default and support unbounded lookahead.

Alcotest exposes simple interface to perform unit tests. It exposes a simple TESTABLE module type, a check function to assert test predicates and a run function to perform a list of unit -> unit test callbacks. Alcotest provides a quiet and colorful output where only faulty runs are fully displayed at the end of the run (with the full logs ready to inspect), with a simple (yet expressive) query language to select the tests to run.

This library provides minimal support for Canonical S-expressions. Canonical S-expressions are a binary encoding of S-expressions that is super simple and well suited for communication between programs.

This library only provides a few helpers for simple applications. If you need more advanced support, such as parsing from more fancy input sources, you should consider copying the code of this library given how simple parsing S-expressions in canonical form is.

To avoid a dependency on a particular S-expression library, the only module of this library is parameterised by the type of S-expressions.

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

Syntax extension for writing in-line benchmarks in ocaml code.

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

Ppx_tools provides tools for authors of ppx rewriters and other syntactic tools.

This package includes only the ocp-index library and command-line tool.
