Cinaps is a trivial Metaprogramming tool using the OCaml toplevel. It is based on the same idea as expectation tests. The user writes some OCaml code inside special comments and cinaps makes sure that what follows is what is printed by the OCaml code.

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.

Bisect_ppx helps you test thoroughly. It is a small preprocessor that inserts instrumentation at places in your code, such as if-then-else and match expressions. After you run tests, Bisect_ppx gives a nice HTML report showing which places were visited and which were missed.

Usage is simple - add package bisect_ppx when building tests, run your tests, then run the Bisect_ppx report tool on the generated visitation files.

Output trace data to a file in Chrome's trace_event format. This format is compatible with chrome trace viewer chrome://tracing. This library offers no backwards compatibility guarantees.

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

Ctypes is a library for binding to C libraries using pure OCaml. The primary aim is to make writing C extensions as straightforward as possible. The core of ctypes is a set of combinators for describing the structure of C types -- numeric types, arrays, pointers, structs, unions and functions. You can use these combinators to describe the types of the functions that you want to call, then bind directly to those functions -- all without writing or generating any C!

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

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

Extensions to printf-style format-strings for user-defined string conversion.

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

Lexer generator for Unicode and OCaml.

OCamlbuild is a generic build tool, that has built-in rules for building OCaml library and programs.

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 library provides minimal support for Canonical S-expressions. Canonical S-expressions are a binary encoding of S-expressions that is super simple and well suited for communication between programs.

This library only provides a few helpers for simple applications. If you need more advanced support, such as parsing from more fancy input sources, you should consider copying the code of this library given how simple parsing S-expressions in canonical form is.

To avoid a dependency on a particular S-expression library, the only module of this library is parameterised by the type of S-expressions.

DSL to describe a set of modules and functors, their types and how to apply them in order to produce a complete application. The main use case is mirage.

Utilities for working with terminal output, such as color printing.

Hex is a minimal library providing hexadecimal converters.

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 package provides an OCaml library for interacting with files in the TOML format. Specifically, it provides a parser, a serializer, and a pretty printer.

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.

OUnit2 is a unit testing framework for OCaml. It is similar to JUnit and other XUnit testing frameworks.

MirageOS OS library for Xen targets, which handles the main loop and timers. It also provides the low level C startup code and C stubs required by the OCaml code.

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.

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