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

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.

Binary Analysis Platform is a framework for writing program analysis tools, that target binary files. The framework consists of a plethora of libraries, plugins, and frontends. The libraries provide code reusability, the plugins facilitate extensibility, and the frontends serve as entry points.

Part of the Jane Street's PPX rewriters collection.

This package is a ppx extension for easier implementation of conversion functions between almost identical types.

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

The OCaml compiler has a bunch of intrinsics for Bigstrings, but they're not widely-known, sometimes misused, and so programs that use Bigstrings are slower than they have to be. And even if a library got that part right and exposed the intrinsics properly, the compiler doesn't have any fast blits between Bigstrings and other string-like types. bigstringaf provides these missing pieces.

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.

Library to provide pure OCaml functions to manipulate real file (POSIX like) and filename.

Ppx_fields_conv is a ppx rewriter that can be used to define first class values representing record fields, and additional routines, to get and set record fields, iterate and fold over all fields of a record and create new record values.

Js_of_ocaml is a compiler from OCaml bytecode to JavaScript. It makes it possible to run pure OCaml programs in JavaScript environment like browsers and Node.js.

Earley is a parser combinator library base on Earley's algorithm. It is intended to be used in conjunction with an OCaml syntax extension which allows the definition of parsers inside the language. There is also support for writing OCaml syntax extensions in a camlp4 style.

Ocb-stubblr is about ten lines of code that you need to repeat over, over, over and over again if you are using ocamlbuild to build OCaml projects that contain C stubs.

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.

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

ppx-sexp-value is a ppx rewriter that simplifies building s-expressions from ocaml values.

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.

Ppx_base is the set of ppx rewriters used for Base.

Note that Base doesn't need ppx to build, it is only used as a verification tool.

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.

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.

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.

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).

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.

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.
