The Core suite of libraries is an alternative to OCaml's standard library that was developed by Jane Street.

This package is a compatibility package for OCaml's standard iterator type starting from 4.07.

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 extension provides a syntax for string interpolation.

This package can automatically generate runtime types from type definitions.

A comprehensive toolbox for ppx development. It features:

• an OCaml AST / parser / pretty-printer snapshot, to create a full frontend independent of the version of OCaml;

• a library for library for ppx rewriters in general, and type-driven code generators in particular;

• a feature-full driver for OCaml AST transformers;

• a quotation mechanism allowing to write values representing the OCaml AST in the OCaml syntax;

• a generator of open recursion classes from type definitions.

This library converts between parsetrees of different OCaml versions. For each version, there is a snapshot of the parsetree and conversion functions to the next and/or previous version.

Ezjsonm provides more convenient (but far less flexible) input and output functions that go to and from [string] values than jsonm. This avoids the need to write signal code, which is useful for quick scripts that manipulate JSON.

This ppx extension is used for deriving a witness that a type is intended to be stable. In this context, stable means that the serialization format will never change. This allows programs running at different versions of the code to safely communicate.

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 package allows one to access information about how the executable was built, such as the version of the project at which it was built or the list of statically linked libraries with their versions. It supports reporting the version from the version control system during development to get an precise reference of when the executable was built.

This package provides types and operations over dates and times.

Ocaml-cairo2 is a binding to Cairo, a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System, Quartz, Win32, image buffers, PostScript, PDF, and SVG file output.

Uuseg is an OCaml library for segmenting Unicode text. It implements the locale independent Unicode text segmentation algorithms to detect grapheme cluster, word and sentence boundaries and the Unicode line breaking algorithm to detect line break opportunities.

The library is independent from any IO mechanism or Unicode text data structure and it can process text without a complete in-memory representation.

DSL to describe a set of modules and functors, their types and how to apply them in order to produce a complete application. The main use case is mirage.

Bindlib is a library allowing the manipulation of data structures with bound variables. It is particularly useful when writing ASTs for programming languages, but also for manipulating terms of the λ-calculus or quantified formulas.

Ocaml-junit is a package for the creation of JUnit XML reports. It provides a typed API to produce valid reports. They are supposed to be accepted by Jenkins.

GSL-OCaml is an interface to the GNU scientific library (GSL) for the OCaml language.

GNU Ocrad is an optical character recognition program based on a feature extraction method. It can read images in PBM, PGM or PPM formats and it produces text in 8-bit or UTF-8 formats.

Tesseract is an optical character recognition (OCR) engine with very high accuracy. It supports many languages, output text formatting, hOCR positional information and page layout analysis. Several image formats are supported through the Leptonica library. It can also detect whether text is monospaced or proportional. Support for the English language is included by default. To add support for more languages, the tesseract-ocr-tessdata-fast package should be installed.

Zinnia is a simple, customizable and portable online hand recognition system based on Support Vector Machines. Zinnia simply receives user pen strokes as a sequence of coordinate data and outputs n-best characters sorted by SVM confidence. To keep portability, Zinnia doesn't have any rendering functionality. In addition to recognition, Zinnia provides training module that allows us to create any hand-written recognition systems with low-cost.

gImageReader is a Qt front-end to Tesseract optical character recognition (OCR) software.

gImageReader supports automatic page layout detection but the user can also manually define and adjust the recognition regions. It is possible to import images from disk, scanning devices, clipboard and screenshots. gImageReader also supports multipage PDF documents. Recognized text is displayed directly next to the image and basic text editing including search/replace and removing of line breaks is possible. Spellchecking for the output text is also supported if the corresponding dictionaries are installed.

This repository contains fast integer versions of trained models for the Tesseract OCR Engine.

This package provides a library that implements the Sun/ONC RPC (remote procedure calls) protocol in a transport-independent manner. It supports both IPv4 and IPv6. ONC RPC is notably used by the network file system (NFS).
