Pcre-ocaml offers library functions for string pattern matching and substitution, similar to the functionality offered by the Perl language.

This package provides types and operations over dates and times.

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.

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.

Topkg is a packager for distributing OCaml software. It provides an API to describe the files a package installs in a given build configuration and to specify information about the package's distribution, creation and publication procedures.

ocaml-dot-merlin-reader is an external reader for ocaml-merlin configurations.

CamlPDF is an OCaml library that provides functionality for reading, writing, and modifying PDF files. It serves as the foundation for the cpdf command-line tool and various API bindings.

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).

Xmlm is a streaming codec to decode and encode the XML data format. It can process XML documents without a complete in-memory representation of the data.

Optimised functions to read and write int16/32/64 from strings and bigarrays, based on new primitives added in version 4.01. It works on strings, bytes and bigstring (Bigarrys of chars), and provides submodules for big- and little-endian, with their unsafe counter-parts.

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.

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

The ocaml-integers library provides a number of 8-, 16-, 32- and 64-bit signed and unsigned integer types, together with aliases such as long and size_t whose sizes depend on the host platform.

Odoc is a documentation generator for OCaml. It reads doc comments, delimited with (** ... *), and outputs HTML.

Text inside doc comments is marked up in ocamldoc syntax. Odoc's main advantage over ocamldoc is an accurate cross-referencer, which handles the complexity of the OCaml module system.

Library to perform parallel fold or map taking advantage of multiple core architectures for OCaml programs. Drop-in replacement for these List operations are provided:

• List.map -> parmap

• List.map -> parfold

• List.mapfold -> parmapfold

Also it allows specifying the number of cores to use with the optional parameter ncores.

Angstrom is a parser-combinator library that makes it easy to write efficient, expressive, and reusable parsers suitable for high-performance applications. It exposes monadic and applicative interfaces for composition, and supports incremental input through buffered and unbuffered interfaces. Both interfaces give the user total control over the blocking behavior of their application, with the unbuffered interface enabling zero-copy IO. Parsers are backtracking by default and support unbounded lookahead.

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.

This package is a line-reading library for OCaml that aims to replace readline.

This package can automatically generate runtime types from type definitions.

Octavius is a library to parse the `ocamldoc` comment syntax.

Uutf is a non-blocking streaming codec to decode and encode the UTF-8, UTF-16, UTF-16LE and UTF-16BE encoding schemes. It can efficiently work character by character without blocking on IO. Decoders perform character position tracking and support newline normalization.

Functions are also provided to fold over the characters of UTF encoded OCaml string values and to directly encode characters in OCaml Buffer.t values.

Dune-configurator is a small library that helps writing OCaml scripts that test features available on the system, in order to generate config.h files for instance. Among other things, dune-configurator allows one to:

• test if a C program compiles

• query pkg-config

• import #define from OCaml header files

• generate config.h file

This library implements a rather complete and efficient monadic parser combinator library similar to the Parsec library for Haskell by Daan Leijen and the FParsec library for FSharp by Stephan Tolksdorf.

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.
