This package simply repackages the OCaml compiler libraries so they don't expose everything at toplevel. For instance, Ast_helper is now Ocaml_common.Ast_helper.

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.

Xmlm is a streaming codec to decode and encode the XML data format. It can process XML documents without a complete in-memory representation of the data.

This package provides two library modules:

• Stream: imperative streams, with in-place update and memoization of the latest element produced.

• Genlex: a small parameterized lexical analyzer producing streams of tokens from streams of characters.

The two modules are designed for use with Camlp4 and Camlp5: The stream patterns and stream expressions of Camlp4/Camlp5 consume and produce data of type 'a Stream.t. The Genlex tokenizer can be used as a simple lexical analyzer for Camlp4/Camlp5-generated parsers.

The Stream module can also be used by hand-written recursive-descent parsers, but is not very convenient for this purpose.

The Stream and Genlex modules have been part of the OCaml standard library for a long time, and have been distributed as part of the core OCaml system. They will be removed from the OCaml standard library at some future point, but will be maintained and distributed separately in the camlpstreams package.

This package generates accessors and iteration functions for OCaml variant types.

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.

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

This package allows one to access information about how the executable was built, such as the version of the project at which it was built or the list of statically linked libraries with their versions. It supports reporting the version from the version control system during development to get an precise reference of when the executable was built.

This OCaml library provides two new integer types, Optint.t and Int63.t, which guarantee efficient representation on 64-bit architectures and provide a best-effort boxed representation on 32-bit architectures.

Compatibility module for OCaml standard library allowing programs to use some recent additions to the standard library while preserving the ability to be compiled on former versions of OCaml.

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.

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.

Contains Async's core data structures, like Deferred. Async_kernel is portable, and so can be used in JavaScript using Async_js.

Ppx_tools provides tools for authors of ppx rewriters and other syntactic tools.

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.

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

OCaml is written in OCaml. Its sources contain a pre-compiled bytecode version of ocamlc and ocamllex that are used to build the next version of the compiler. Camlboot implements a bootstrap for the OCaml compiler and provides a bootstrapped equivalent to these files.

It contains a compiler for a small subset of OCaml written in Guile Scheme, an interpreter for OCaml written in that subset and a manually-written lexer for OCaml. These elements eliminate the need for the binary bootstrap in OCaml and can effectively bootstrap OCaml 4.07.

This package produces a native ocamlc and a bytecode ocamllex.

This package provides a library for parsing the contents of OCaml documentation comments, formatted using Odoc syntax, an extension of the language understood by ocamldoc.

IO pages are page-aligned, and wrapped in the Cstruct library to avoid copying the data contained within the page.

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.

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.

Library for passing boot parameters from Solo5 to MirageOS.

Client-side URL transfer library, supporting HTTP and a multitude of other network protocols (FTP/SMTP/RTSP/etc).

This package provides OCaml bindings to the Linux io_uring kernel IO interfaces.
