This package provides a GLR parser generator for OCaml. It is able to generate self-extensible parsers (also called adaptive parsers) as well as extensible lexers for the parsers it produces.

This package contains an syntax extension to indicate that the code is on the cold path and should be kept out of the way to avoid polluting the instruction cache on the hot path. See also https://github.com/ocaml/ocaml/issues/8563.

This package provides a duration is represented in nanoseconds as an unsigned 64 bit integer. This has a range of up to 584 years. Functions provided check the input and raise on negative or out of bound input.

Lexer generator for Unicode and OCaml.

Ppx_derivers is a tiny package whose sole purpose is to allow ppx_deriving and ppx_type_conv to inter-operate gracefully when linked as part of the same ocaml-migrate-parsetree driver.

This ocaml library returns user XDG directories such as XDG_CONFIG_HOME, XDG_STATE_HOME.

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.

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.

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.

This package is a collection of ppx rewriters that generate hash functions from type exrpessions and definitions.

Bos provides support for basic and robust interaction with the operating system in OCaml. It has functions to access the process environment, parse command line arguments, interact with the file system and run command line programs.

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

ANSITerminal is a module allowing to use the colors and cursor movements on ANSI terminals.

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.

Menhir is a parser generator. It turns high-level grammar specifications, decorated with semantic actions expressed in the OCaml programming language into parsers, again expressed in OCaml. It is based on Knuth’s LR(1) parser construction technique.

Library for pretty-printing s-expressions, using better indentation rules than the default pretty printer in Sexplib.

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

Syntax extension to define first class values representing record fields, to get and set record fields, iterate and fold over all fields of a record and create new record values.

OCaml-SSL is a set of bindings for OpenSSL, a library for communicating through Transport Layer Security (TLS) encrypted connections.

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

Uucp is an OCaml library providing efficient access to a selection of character properties of the Unicode character database.

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

Generation of fast comparison functions from type expressions and definitions. Ppx_compare is a ppx rewriter that derives comparison functions from type representations. The scaffolded functions are usually much faster than ocaml's Pervasives.compare. Scaffolding functions also gives you more flexibility by allowing you to override them for a specific type and more safety by making sure that you only compare comparable values.
