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

This module implements purely in OCaml a character width function that follows the prototype of POSIX's wcwidth.

afl-fuzz normally works by repeatedly forking the program being tested. Using this package, you can run afl-fuzz in ``persistent mode'', which avoids repeated forking and is much faster.

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.

This package contains a compatibility library for Stdlib.Bigarray in OCaml.

This package contains a syntax extension for writing in-line tests in ocaml code. It is part of Jane Street's PPX rewriters collection.

base-quickcheck provides randomized testing in the style of Haskell's Quickcheck library, with support for built-in types as well as types provided by Base.

Ppx_fields_conv is a ppx rewriter that can be used to define first class values representing record fields, and additional routines, to get and set record fields, iterate and fold over all fields of a record and create new record values.

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 package can automatically generate runtime types from type definitions.

The subset of textutils using only core_kernel and working in javascript.

Modules using ppx_module_timer have instrumentation to record their startup time.

This package contains a parser and a pretty-printer for the opam file format.

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.

Ppx_sexp_message aims to ease the creation of s-expressions in OCaml. This is mainly motivated by writing error and debugging messages, where one needs to construct a s-expression based on various element of the context such as function arguments.

This is the runtime support library for code generated by functoria.

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

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

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

This package contains deriving conversion functions to and from yaml for OCaml types.

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

This library converts between parsetrees of different OCaml versions. For each version, there is a snapshot of the parsetree and conversion functions to the next and/or previous version.

This package provides a splittable PRNG functions like a PRNG that can be used as a stream of random values; it can also be split to produce a second, independent stream of random values.

This library implements a splittable pseudo-random number generator that sacrifices cryptographic-quality randomness in favor of performance.

This package provides an ESS-like binding to send lines or regions to a REPL from OCaml buffers.
