Enter the query into the form above. You can look for specific version of a package by using @ symbol like this: gcc@10.
API method:
GET /api/packages?search=hello&page=1&limit=20
where search is your query, page is a page number and limit is a number of items on a single page. Pagination information (such as a number of pages and etc) is returned
in response headers.

This package installs a ppx-jane executable, which is a ppx driver including all standard Jane Street ppx rewriters.
Cmdliner is a module for the declarative definition of command line interfaces. It provides a simple and compositional mechanism to convert command line arguments to OCaml values and pass them to your functions. The module automatically handles syntax errors, help messages and UNIX man page generation. It supports programs with single or multiple commands and respects most of the POSIX and GNU conventions.
The OCaml compiler has a bunch of intrinsics for Bigstrings, but they're not widely-known, sometimes misused, and so programs that use Bigstrings are slower than they have to be. And even if a library got that part right and exposed the intrinsics properly, the compiler doesn't have any fast blits between Bigstrings and other string-like types. bigstringaf provides these missing pieces.
Library for passing boot parameters from Solo5 to MirageOS.
This OCaml library offers a set of combinators for building so-called documents as well as an efficient engine for converting documents to a textual, fixed-width format. The engine takes care of indentation and line breaks, while respecting the constraints imposed by the structure of the document and by the text width.
Comma separated values (CSV) is a simple tabular format supported by all major spreadsheets. This library implements pure OCaml functions to read and write files in this format as well as some convenience functions to manipulate such data.
Ignore Jane Street specific instrumentation extensions from internal PPXs or compiler features not yet upstreamed.
OPAM is a tool to manage OCaml packages. It supports multiple simultaneous compiler installations, flexible package constraints, and a Git-friendly development workflow.
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.
SQLite3-OCaml is an OCaml library with bindings to the SQLite3 client API. Sqlite3 is a self-contained, serverless, zero-configuration, transactional SQL database engine with outstanding performance for many use cases. These bindings are written in a way that enables a friendly coexistence with the old (version 2) SQLite and its OCaml wrapper ocaml-sqlite.
Handle computation results and errors in an explicit and declarative manner, without resorting to exceptions. It defines combinators to operate on the result type available from OCaml 4.03 in the standard library.
Typerep is a library for runtime types.
Client-side URL transfer library, supporting HTTP and a multitude of other network protocols (FTP/SMTP/RTSP/etc).
DSL to describe a set of modules and functors, their types and how to apply them in order to produce a complete application. The main use case is mirage.
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.
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 is the runtime support library for code generated by functoria.
Uucp is an OCaml library providing efficient access to a selection of character properties of the Unicode character database.
Provides a single function to report the current time in nanoseconds since the start of the Unix epoch.
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.
This library contains functionality for reading and writing OCaml-values in a type-safe binary protocol. It is extremely efficient, typically supporting type-safe marshalling and unmarshalling of even highly structured values at speeds sufficient to saturate a gigabit connection. The protocol is also heavily optimized for size, making it ideal for long-term storage of large amounts of data.
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.
Angstrom is a parser-combinator library that makes it easy to write efficient, expressive, and reusable parsers suitable for high-performance applications. It exposes monadic and applicative interfaces for composition, and supports incremental input through buffered and unbuffered interfaces. Both interfaces give the user total control over the blocking behavior of their application, with the unbuffered interface enabling zero-copy IO. Parsers are backtracking by default and support unbounded lookahead.
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.
