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.

The Core suite of libraries is an alternative to OCaml's standard library.

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.

This library provides an alternative to the Format module of the OCaml standard library. Pp uses the same concepts of boxes and break hints, and the final rendering is done to formatter from the Format module. However it defines its own algebra which some might find easier to work with and reason about.

Provides a single module named Stringext that provides a grab bag of often used but missing string functions from the stdlib. E.g, split, full_split, cut, rcut, etc..

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.

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.

opam-installer is a tool for installing OCaml packages based on .install files defined by the OPAM package manager. It is useful for installing OCaml packages without requiring the entirety of OPAM.

Helper functions for writing expect tests.

Comma separated values (CSV) is a simple tabular format supported by all major spreadsheets. This library implements pure OCaml functions to read and write files in this format as well as some convenience functions to manipulate such data.

Used to trace execution of OCaml/Lwt programs (such as Mirage unikernels) at the level of Lwt threads. The traces can be viewed using JavaScript or GTK viewers provided by mirage-trace-viewer or processed by tools supporting the Common Trace Format. When compiled against a normal version of Lwt, OCaml's cross-module inlining will optimise these calls away, meaning there should be no overhead in the non-profiling case.

This package contains a parser and a pretty-printer for the opam file format.

This package is an OCaml library to parse and generate the YAML file format. It is intended to be interoperable with the Ezjsonm JSON handling library, if the simple common subset of Yaml is used. Anchors and other advanced Yaml features are not implemented in the JSON compatibility layer.

Cohttp is an OCaml library for creating HTTP daemons. It has a portable HTTP parser, and implementations using various asynchronous programming libraries.

Monolith offers facilities for testing an OCaml library (for instance, a data structure implementation) by comparing it against a reference implementation. It can be used to perform either random testing or fuzz testing by using the afl-fuzz tool.

Lwt provides typed, composable cooperative threads. These make it easy to run normally-blocking I/O operations concurrently in a single process. Also, in many cases, Lwt threads can interact without the need for locks or other synchronization primitives.

This package backports some of the new stdlib features to older compilers, such as the Stdlib module. This allows projects that require compatibility with older compiler to use these new features in their code.

The uchar package provides a compatibility library for the `Uchar` module introduced in OCaml 4.03.

Libraries for creating shared memory producer/consumer rings. The rings follow the Xen ABI and may be used to create or implement Xen virtual devices.

Ppx_yojson_conv_lib is the runtime library used by ppx_yojson_conv, a ppx rewriter that can be used to convert ocaml types to a Yojson.Safe value.

Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. It is specified in RFC 4648.

This library provides generic parsers for parsing S-expressions from strings or other medium.

The library is focused on performances but still provide full generic parsers that can be used with strings, bigstrings, lexing buffers, character streams or any other sources effortlessly.

It provides three different class of parsers:

• the normal parsers, producing [Sexp.t] or [Sexp.t list] values

• the parsers with positions, building compact position sequences so that one can recover original positions in order to report properly located errors at little cost

• the Concrete Syntax Tree parsers, produce values of type Parsexp.Cst.t which record the concrete layout of the s-expression syntax, including comments

This library is portable and doesn't provide IO functions. To read s-expressions from files or other external sources, you should use parsexp_io.

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.

Tuareg helps editing OCaml code, to highlight important parts of the code, to run an OCaml REPL, and to run the OCaml debugger within Emacs.
