Vi is the original screen based text editor for Unix systems. It is considered the standard text editor, and is available on almost all Unix systems. Nvi is intended as a "bug-for-bug compatible" clone of the original BSD vi editor. As such, it doesn't have a lot of snazzy features as do some of the other vi clones such as elvis and vim. However, if all you want is vi, this is the one to get.

NX is a software suite which implements very efficient compression of the X11 protocol. This increases performance when using X applications over a network, especially a slow one. This package provides the following libraries:

NX_X11

NX's modified X Window System (X11) library

Xcomp

NX differential compression library for X11

Xcompshad

Session shadowing library

The following commands are also provided:

nxagent

Agent providing NX transport of X sessions

nxproxy

The NX proxy (client) binary

nxdialog

Helper script

X2Go enables you to access a graphical desktop of a computer via SSH (Secure Shell). This package provides the X2Go Client, which can connect to the X2Go Server. Basic features of X2Go include:

• Graphical remote desktop that works well over both low bandwidth and high bandwidth connections

• The ability to disconnect and reconnect to a session, even from another client

• Support for sound

• Support for as many simultaneous users as the computer's resources will allow

• Traffic is securely tunneled over SSH

• File sharing from client to server

• Printer sharing from client to server

• Easily select from multiple desktop environments (e.g., MATE, GNOME, KDE)

• Remote support possible via desktop sharing

• The ability to access single applications by specifying the name of the desired executable in the client configuration or selecting one of the pre-defined common applications.

Camlp5 is a Pre-Processor-Pretty-Printer for Objective Caml. It offers tools for syntax (Stream Parsers and Grammars) and the ability to modify the concrete syntax of the language (Quotations, Syntax Extensions).

The graphics library provides a set of portable drawing primitives. Drawing takes place in a separate window that is created when Graphics.open_graph is called. This library used to be distributed with OCaml up to OCaml 4.08.

Library that allows OCaml programs to interact with Python modules and objects. The library also provides low-level bindings to the Python C API.

This library is an alternative to pycaml which is no longer maintained. The Pycaml module provides a signature close to pycaml, to ease migration of code to this library.

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 ocaml library returns user XDG directories such as XDG_CONFIG_HOME, XDG_STATE_HOME.

Qtest extracts inline unit tests written using a special syntax in comments. Those tests are then run using the oUnit framework and the qcheck library. The possibilities range from trivial tests -- extremely simple to use -- to sophisticated random generation of test cases.

This package implements an Ocaml language server implementation.

This package allows you to produce, from a set of bibliography files in BibTeX format, a bibliography in HTML format.

This package allows parsing of dates that follow the ISO 8601 and RFC 3339 formats in OCaml.

This package implements an Ocaml language server implementation.

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.

Lacaml interfaces the BLAS-library (Basic Linear Algebra Subroutines) and LAPACK-library (Linear Algebra routines). It also contains many additional convenience functions for vectors and matrices.

This package provides two union-find data structure implementations for OCaml. Both implementations are based on disjoint sets forests, with path compression and linking-by-rank, so as to guarantee good asymptotic complexity: every operation requires a quasi-constant number of accesses to the store.

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.

This package provides the lablgtk interface to the GTK+ gtksourceview library.

Menhir is a parser generator. It turns high-level grammar specifications, decorated with semantic actions expressed in the OCaml programming language into parsers, again expressed in OCaml. It is based on Knuth’s LR(1) parser construction technique.

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.

This OCaml library offers a set of combinators for building so-called documents as well as an efficient engine for converting documents to a textual, fixed-width format. The engine takes care of indentation and line breaks, while respecting the constraints imposed by the structure of the document and by the text width.

Spawn is a small library exposing only one functionality: spawning sub-process.

It has three main goals:

• provide missing features of Unix.create_process such as providing a working directory,

• provide better errors when a system call fails in the sub-process. For instance if a command is not found, you get a proper Unix.Unix_error exception,

• improve performances by using vfork when available. It is often claimed that nowadays fork is as fast as vfork, however in practice fork takes time proportional to the process memory while vfork is constant time. In application using a lot of memory, vfork can be thousands of times faster than fork.

Small implementation of a simple argv parser.

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.
