Unix-related dependencies for things like system calls and threads. Using these, it hooks the Async_kernel scheduler up to either epoll or select, depending on availability, and manages a thread pool that blocking system calls run in.

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 module provides a set of tools to measure the running times of your functions and to easily compare the results. A statistical test is used to determine whether the results truly differ.

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).

Down is an unintrusive user experience upgrade for the ocaml toplevel (REPL).

Simply load the zero dependency down library in the ocaml toplevel and you get line edition, history, session support and identifier completion and documentation with ocp-index.

Add this to your ~/.ocamlinit:

#use "down.top"

You may also need to add this to your ~/.ocamlinit and declare the environment variable OCAML_TOPLEVEL_PATH:

let () =
  try Topdirs.dir_directory (Sys.getenv "OCAML_TOPLEVEL_PATH")
  with Not_found -> ()

OR

let () = String.split_on_char ':' (Sys.getenv "OCAMLPATH")
         |> List.filter (fun x -> Filename.check_suffix x "/site-lib")
         |> List.map (fun x -> x ^ "/toplevel")
         (* remove the line below if you don't want to see the text
            every time you start the toplevel *)
         |> List.map (fun x -> Printf.printf "adding directory %s\n" x; x)
         |> List.iter Topdirs.dir_directory;;

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

IP address types with serialization, supporting a wide range of RFCs.

Defines the signature for time-related operations for MirageOS.

Pure OCaml regular expressions with:

1. Perl-style regular expressions (module Re_perl)

2. Posix extended regular expressions (module Re_posix)

3. Emacs-style regular expressions (module Re_emacs)

4. Shell-style file globbing (module Re_glob)

5. Compatibility layer for OCaml's built-in Str module (module Re_str)

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

This module provides a vi-like modal editing engine generator.

Traditional implementation of priority queues using a binary heap encoded in a resizable array.

OCaml-uri is a library for parsing URI/URL in the RFC3986 format.

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

This library is a compatibility module for the Either module defined in OCaml 4.12.0.

ppx-fixed-literal is a ppx rewriter that rewrites fixed point literal of the form 1.0v to conversion functions currently in scope.

Dune-configurator is a small library that helps writing OCaml scripts that test features available on the system, in order to generate config.h files for instance. Among other things, dune-configurator allows one to:

• test if a C program compiles

• query pkg-config

• import #define from OCaml header files

• generate config.h file

ppx_bap is the set of blessed ppx rewriters used in BAP projects. It fills the same role as ppx_base or ppx_jane (from which it is derived), but doesn't impose any style requirements and has only the minimal necessary set of rewriters.

Syntax extension that makes [failwiths] always include a position.

Expect-test is a framework for writing tests in OCaml, similar to Cram. Expect-tests mimics the existing inline tests framework with the let%expect_test construct. The body of an expect-test can contain output-generating code, interleaved with %expect extension expressions to denote the expected output.

Part of the Jane Street's PPX rewriters collection.

Lexer generator for Unicode and OCaml.

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

Uses a Mirage CLOCK to write timestamped log messages. It can also log only important messages to the console, while writing all received messages to a ring buffer which is displayed if an exception occurs. If tracing is enabled (via mirage-profile), it also writes each log message to the trace buffer.
