This library adds new functions to OCaml standard library modules, modifies some functions in order to get better performances or safety (tail-recursive) and also provides new modules which should be useful for day to day programming.

This module implements strict impure trie tree data structure for OCaml.

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.

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.

Features:

• MAC-48 (Ethernet) address support

• Macaddr is a Map.OrderedType

• All types have sexplib serializers/deserializers optionally via the Macaddr_sexp library

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).

The opam monorepo plugin provides a convenient interface to bridge the opam package manager with having a local copy of all the source code required to build a project using the dune build tool.

This package provides types and operations over dates and times.

An implementation inspired by Okasaki & Gill's paper 'Fast Mergeable Integer Maps.'

This package provides a way to write bitstrings and matching over bitsrings in Erlang style as primitives to the language.

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.

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

Tsdl is an OCaml library providing thin bindings to the cross-platform SDL C library.

OASIS is a tool to integrate a configure, build and install system in your OCaml projects. It helps to create standard entry points in your build system and allows external tools to analyse your project easily.

Ppx_deriving_yojson is a ppx_deriving plugin that provides a JSON codec generator.

Uses the new result type defined in OCaml >= 4.03 while staying compatible with older version of OCaml should use the Result module defined in this library.

Pure OCaml regular expressions with:

1. Perl-style regular expressions (module Re_perl)

2. Posix extended regular expressions (module Re_posix)

3. Emacs-style regular expressions (module Re_emacs)

4. Shell-style file globbing (module Re_glob)

5. Compatibility layer for OCaml's built-in Str module (module Re_str)

This package implements an Ocaml language server implementation.

Uuidm is an OCaml module implementing 128 bits universally unique identifiers (UUIDs) version 3, 5 (named based with MD5, SHA-1 hashing) and 4 (random based) according to RFC 4122.

Access monotonic wall-clock time. It measures time spans without being subject to operating system calendar time adjustments.

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.

Cstruct is a library and syntax extension to make it easier to access C-like structures directly from OCaml. It supports both reading and writing to these structures, and they are accessed via the Bigarray module.

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.

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