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

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.

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.

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 provides facilities to parse version numbers of the OCaml compiler, and enumerates the various official OCaml releases and configuration variants.

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.

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

Eio_luv provides a cross-platform backend for Ocaml Eio's APIs using luv (libuv)

This package implements an Ocaml language server implementation.

This package provides a library for parsing the contents of OCaml documentation comments, formatted using Odoc syntax, an extension of the language understood by ocamldoc.

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

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

Uunf is an OCaml library for normalizing Unicode text. It supports all Unicode normalization forms. The library is independent from any IO mechanism or Unicode text data structure and it can process text without a complete in-memory representation.

Used to trace execution of OCaml/Lwt programs (such as Mirage unikernels) at the level of Lwt threads. The traces can be viewed using JavaScript or GTK viewers provided by mirage-trace-viewer or processed by tools supporting the Common Trace Format. When compiled against a normal version of Lwt, OCaml's cross-module inlining will optimise these calls away, meaning there should be no overhead in the non-profiling case.

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.

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.

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.

This library implements portable support for an operating system timesource that is compatible with the MirageOS library interfaces. It implements an MCLOCK module that represents a monotonic timesource since an arbitrary point, and PCLOCK which counts time since the Unix epoch.

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

Fmt exposes combinators to devise Format pretty-printing functions.

Xml-Light provides functions to parse an XML document into an OCaml data structure, work with it, and print it back to an XML document. It also supports DTD parsing and checking, and is entirely written in OCaml, hence it does not require additional C libraries.

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.

OCamlgraph is a generic graph library for OCaml.

CamlPDF is an OCaml library that provides functionality for reading, writing, and modifying PDF files. It serves as the foundation for the cpdf command-line tool and various API bindings.
