OCamlFormat is a tool to automatically format OCaml code in a uniform style. This package defines a RPC interface to OCamlFormat.

Unison is a file-synchronization tool. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.

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.

Ppx_enumerate is a ppx rewriter which generates a definition for the list of all values of a type (for a type which only has finitely many values).

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.

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

Fpath is an OCaml module for handling file system paths with POSIX or Windows conventions. Fpath processes paths without accessing the file system and is independent from any system library.

A ppx rewriter that rewrites simple match statements with an if then else expression.

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

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 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.

ppx-sexp-value is a ppx rewriter that simplifies building s-expressions from ocaml values.

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!

Lexer generator for Unicode and OCaml.

This library implements structured concurrency for ocaml. It offers no backwards compatibility guarantees.

Library for asynchronous programming, i.e., programming where some part of the program must wait for things that happen at times determined by some external entity (like a human or another program).

Fmt exposes combinators to devise Format pretty-printing functions.

Library for building RPC-style protocols. This library is the portable part of the Unix-oriented Async_rpc library, and is actively used in JavaScript.

This project provides a Mmap.map_file function for mapping files in memory. This function is the same as the Unix.map_file function added in OCaml >= 4.06.

Implements arithmetic and logical operations over arbitrary-precision integers. It uses GMP to efficiently implement arithmetic over big integers. Small integers are represented as Caml unboxed integers, for speed and space economy.

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

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.

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.

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