This library represents element ordering in OCaml.

Ppx_yojson_conv_lib is the runtime library used by ppx_yojson_conv, a ppx rewriter that can be used to convert ocaml types to a Yojson.Safe value.

This package generates JUnit XML reports from ocaml-alcotest test suites.

ppx-sexp-value is a ppx rewriter that simplifies building s-expressions from ocaml values.

This package generates accessors and iteration functions for OCaml variant types.

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

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.

Part of the Jane Street's PPX rewriters collection.

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.

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.

This library implements a rather complete and efficient monadic parser combinator library similar to the Parsec library for Haskell by Daan Leijen and the FParsec library for FSharp by Stephan Tolksdorf.

This package can automatically generate runtime types from type definitions.

This is the runtime support library for code generated by functoria.

Easy-format is a high-level and functional interface to the Format module of the OCaml standard library.

Small implementation of a simple argv parser.

Merlin is an editor service that provides modern IDE features for OCaml. Emacs and Vim support is provided out-of-the-box. External contributors added support for Visual Studio Code, Sublime Text and Atom.

This package backports new language features such as let+ to older OCaml compilers.

This ppx extension is used for deriving a witness that a type is intended to be stable. In this context, stable means that the serialization format will never change. This allows programs running at different versions of the code to safely communicate.

OCaml is a general purpose industrial-strength programming language with an emphasis on expressiveness and safety. Developed for more than 20 years at Inria it benefits from one of the most advanced type systems and supports functional, imperative and object-oriented styles of programming.

Piqilib is the common library used by the piqi command-line tool and piqi-ocaml.

This package is a no-op ppx rewriter. It is used as a lint tool to enforce some coding conventions across all Jane Street packages.

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_sexp_message aims to ease the creation of s-expressions in OCaml. This is mainly motivated by writing error and debugging messages, where one needs to construct a s-expression based on various element of the context such as function arguments.

This module provides a set of tools to measure the running times of your functions and to easily compare the results. A statistical test is used to determine whether the results truly differ.
