Lambda-Term is a cross-platform library for manipulating the terminal. It provides an abstraction for keys, mouse events, colors, as well as a set of widgets to write curses-like applications. The main objective of Lambda-Term is to provide a higher level functional interface to terminal manipulation than, for example, ncurses, by providing a native OCaml interface instead of bindings to a C library.

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 provides PCRE-based regular expressions support for Mparser.

A ppx rewriter that inlines reverse application operators |> and |!.

Generation of binary serialization and deserialization functions from type definitions.

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

A ppx rewriter that rewrites simple match statements with an if then else expression.

ANSITerminal is a module allowing to use the colors and cursor movements on ANSI terminals.

Ppx_deriving provides common infrastructure for generating code based on type definitions, and a set of useful plugins for common tasks.

Contains Async's core data structures, like Deferred. Async_kernel is portable, and so can be used in JavaScript using Async_js.

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.

Output trace data to a file in Chrome's trace_event format. This format is compatible with chrome trace viewer chrome://tracing. This library offers no backwards compatibility guarantees.

Eio_linux provides a Linux io-uring backend for Ocaml Eio APIs, plus a low-level API that can be used directly (in non-portable code).

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.

This package backports some of the new stdlib features to older compilers, such as the Stdlib module. This allows projects that require compatibility with older compiler to use these new features in their code.

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.

React is an OCaml module for functional reactive programming (FRP). It provides support to program with time varying values: declarative events and signals. React doesn't define any primitive event or signal, it lets the client chooses the concrete timeline.

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 implements an Ocaml language server implementation.

This package provides an OCaml library for calling OCamlFormat remotely.

This package generates S-expression conversion functions from type definitions.

These libraries provides access to low-level compiler interfaces and the standard higher-level merlin protocol.
