This OCaml library provides an implementation of a mutable doubly-linked list with Lwt iterators.

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.

Ppx_optcomp stands for Optional Compilation. It is a tool used to handle optional compilations of pieces of code depending of the word size, the version of the compiler, ...

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.

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

Parses and constructs RFC compliant domain names. The invariants on the length of domain names are preserved throughout the module.

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.

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.

This package provides the core modules of Modal Editing Witch, a general modal editing engine generator.

This project provides a Mmap.map_file function for mapping files in memory. This function is the same as the Unix.map_file function added in OCaml >= 4.06.

Ignore Jane Street specific instrumentation extensions from internal PPXs or compiler features not yet upstreamed.

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.

This package implements an Ocaml language server implementation.

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.

Syntax extension that makes [failwiths] always include a position.

IO pages are page-aligned, and wrapped in the Cstruct library to avoid copying the data contained within the page.

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 package is an OCaml library to parse and generate the YAML file format. It is intended to be interoperable with the Ezjsonm JSON handling library, if the simple common subset of Yaml is used. Anchors and other advanced Yaml features are not implemented in the JSON compatibility layer.

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.

ppx-fixed-literal is a ppx rewriter that rewrites fixed point literal of the form 1.0v to conversion functions currently in scope.

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.

Modules using ppx_module_timer have instrumentation to record their startup time.

This library represents dynamic types in OCaml.
