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.

Ptime offers platform independent POSIX time support in pure OCaml. It provides a type to represent a well-defined range of POSIX timestamps with picosecond precision, conversion with date-time values, conversion with RFC 3339 timestamps and pretty printing to a human-readable, locale-independent representation.

Part of the Jane Street's PPX rewriters collection.

SQLite3-OCaml is an OCaml library with bindings to the SQLite3 client API. Sqlite3 is a self-contained, serverless, zero-configuration, transactional SQL database engine with outstanding performance for many use cases. These bindings are written in a way that enables a friendly coexistence with the old (version 2) SQLite and its OCaml wrapper ocaml-sqlite.

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.

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.

This library represents dynamic types in OCaml.

Timezone handles parsing timezone data and create Timezone.t that can later be used to manipulate time in core_kernel or core.

This library provides Functional Priority Search Queues for OCaml. Typical applications are searches, schedulers and caches.

Ppx_optcomp stands for Optional Compilation. It is a tool used to handle optional compilations of pieces of code depending of the word size, the version of the compiler, ...

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.

OCamlFormat is a tool to automatically format OCaml code in a uniform style.

Logs provides a logging infrastructure for OCaml. Logging is performed on sources whose reporting level can be set independently. Log message report is decoupled from logging and is handled by a reporter.

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.

Defines compile-time constants used in Jane Street libraries such as Base, Core, and Async. This package has an unstable interface; it is intended only to share configuration between different packages from Jane Street. Future updates may not be backward-compatible, and we do not recommend using this package directly.

OCaml is a general purpose industrial-strength programming language with an emphasis on expressiveness and safety. Developed for more than 20 years at Inria it benefits from one of the most advanced type systems and supports functional, imperative and object-oriented styles of programming.

Timed references for imperative state. This module provides an alternative type for references (or mutable cells) supporting undo/redo operations. In particular, an abstract notion of time is used to capture the state of the references at any given point, so that it can be restored. Note that usual reference operations only have a constant time / memory overhead (compared to those of the standard library).

Moreover, we provide an alternative implementation based on the references of the standard library (Pervasives module). However, it is less efficient than the first one.

Parses and constructs RFC compliant domain names. The invariants on the length of domain names are preserved throughout the module.

Bindings providing OCaml support for the seminal Fast Fourier Transform library FFTW.

This package contains assert-like extension nodes that raise useful errors on failure.

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.

This package adds S-exp support to ocaml-uri.

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.

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.
