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.

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

This package provides PCRE-based regular expressions support for Mparser.

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.

Piqi is a multi-format data serialization system for OCaml. It provides a uniform interface for serializing OCaml data structures to JSON, XML and Protocol Buffers formats.

HeVeA is a LaTeX to HTML translator that generates modern HTML 5. It is written in Objective Caml.

This package can automatically generate runtime types from type definitions.

Modules using ppx_module_timer have instrumentation to record their startup time.

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.

This package implements an Ocaml language server implementation.

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

Ppx_derivers is a tiny package whose sole purpose is to allow ppx_deriving and ppx_type_conv to inter-operate gracefully when linked as part of the same ocaml-migrate-parsetree driver.

Library for building RPC-style protocols. This library is the portable part of the Unix-oriented Async_rpc library, and is actively used in JavaScript.

Xmlm is a streaming codec to decode and encode the XML data format. It can process XML documents without a complete in-memory representation of the data.

TyXML provides a set of convenient combinators that uses the OCaml type system to ensure the validity of the generated documents. TyXML can be used with any representation of HTML and SVG: the textual one, provided directly by this package, or DOM trees (js_of_ocaml-tyxml) virtual DOM (virtual-dom) and reactive or replicated trees (eliom). You can also create your own representation and use it to instantiate a new set of combinators.

The "findlib" library provides a scheme to manage reusable software components (packages), and includes tools that support this scheme. Packages are collections of OCaml modules for which metainformation can be stored. The packages are kept in the file system hierarchy, but with strict directory structure. The library contains functions to look the directory up that stores a package, to query metainformation about a package, and to retrieve dependency information about multiple packages. There is also a tool that allows the user to enter queries on the command-line. In order to simplify compilation and linkage, there are new frontends of the various OCaml compilers that can directly deal with packages.

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.

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.

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.

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

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

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

Js_of_ocaml is a compiler from OCaml bytecode to JavaScript. It makes it possible to run pure OCaml programs in JavaScript environment like browsers and Node.js.

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