Open Source OCaml (Objective Caml) Software

Audio toolkit for streaming, aiming at complex Internet radio systems. Our stream generator is highly extensible and flexible. Script based, it can be a fully automatic daemon streamer, but is also used for live shows with an user-friendly GUI.

pdfsandwich generates "sandwich" OCR pdf files, i.e. pdf files which contain only images (but no editable text) will be processed by optical character recognition (OCR) and the text will be added to each page invisibly "behind" the images. pdfsandwich is a command line tool which is supposed to be useful to OCR scanned books or journals. It is able to recognize the page layout even for multicolumn text. Essentially, pdfsandwich is a wrapper script which calls the following binaries: convert, unpaper, tesseract, gs, and hocr2pdf (if tesseract < 3.03). It is known to run on Unix systems and has been tested on Linux and MacOS X. It supports parallel processing on multiprocessor systems. In contrast to most competing sandwich programs, it performs preprocessing of the scanned images, such as de-skewing or removal of dark edges etc. For further information please read the manual: http://www.tobias-elze.de/pdfsandwich/index.html

Opam is a source-based package manager for OCaml. It supports multiple simultaneous compiler installations, flexible package constraints, and a Git-friendly development workflow. Opam was created and is maintained by OCamlPro. To get started, checkout the Install and Usage guides. Run ./configure. If you don't have the dependencies installed, this will locally take care of all OCaml dependencies for you (downloading them, unless you used the inclusive archive we provide for each release). This is all you need for installing and using opam, but if you want to use the opam-lib (to work on opam-related tools), you need to link it to installed libraries. It's easier to already have a working opam installation in this case, so you can do it as a second step. If you install on your system (without changing the prefix), you will need to install as root (sudo). As sudo do not propagate environment variables, there wil be some errors.

MLDonkey is a multi-platform multi-network peer-to-peer client.

OCaml is a general-purpose, industrial-strength programming language with an emphasis on expressiveness and safety. OCaml’s powerful type system means more bugs are caught at compile-time, and large, complex codebases are easier to maintain. This makes it a good language for running critical code. At the same time, sophisticated inference makes the type system unobtrusive, creating a smooth developer experience. OCaml has two compilers. One is a bytecode compiler that generates small, portable executables and is very fast. The other is a native code compiler that produces more efficient machine code; its performance matches the highest standards of modern compilers. OCaml has great support for the most popular editors. VS Code is recommended for beginners, and for power users there is deep integration with Vim and Emacs. OCaml has a rich and dynamic community and best-in-class tooling.

Flow is a static type checker for JavaScript. It was designed to help improve code quality and developer productivity. It does this through several smart capabilities. First, it identifies problems as you code, so you no longer have to waste time guessing and checking again and again. Second, it understands your code and makes its knowledge available, allowing you to build other smart tools on top of it. Third, it helps you refactor safely so you can focus on the changes you want to make and not on what you might break. Lastly, it can help prevent bad rebases and protect your carefully designed library, which is especially relevant when working with a large group of developers. Flow integrates with many tools, so you can easily and seamlessly insert it into your existing workflow and toolchain.

A programming framework for building type-safe, modular systems. MirageOS is a library operating system that constructs unikernels for secure, high-performance network applications across a variety of cloud computing and mobile platforms. Code can be developed on a normal OS such as Linux or macOS, and then compiled into a fully standalone, specialized unikernel that runs under a Xen or KVM hypervisor. This lets your services run more efficiently, securely and with finer control than with a full conventional software stack.

Static analysis at ludicrous speed. Find bugs and enforce code standards. Find and prevent security issues in Terraform, Docker, Kubernetes, nginx, and AWS configs before they go into production. Go beyond application code and protect the entire stack with a breadth of scanning capabilities. Don't leak secrets, scan every commit and ensure secrets don't make it to production. Protect the privileged CI/CD environment from malicious activity that could result in access to source code, secrets, and more. Run with registry rules or your own. Code is analyzed locally (not uploaded). Get results at ludicrous speed with diff-aware scans, review findings in MR and PR comments, and deploy Semgrep across your organization’s projects. Go beyond the registry with rules specific to your organization. Write rules to enforce your own code guardrails.

Renderer for flam3 cosmic recursive fractal flames implemented on GPU. Requires a CUDA-capable graphics card.

OCamlSDL is an OCaml interface to the SDL (Simple DirectMedia Layer) library.

google-drive-ocamlfuse is a FUSE-based file system for Google Drive, written in OCaml. It lets you mount your Google Drive on Linux. The project is hosted on GitHub, where you can find the latest development version. Project documentation is hosted in the website. There are Ubuntu packages in this PPA. Read-only access to Google Docs, Sheets, and Slides (exported to configurable formats). Read-ahead buffers when streaming. Accessing content shared with you (requires configuration). Team Drive support. Service account support. OAuth2 for Devices Support. Note that in order to reduce latency, the application will query the server and check for changes only every 60 seconds (configurable). So, if you make a change to your documents (server side), you won't see it immediately in the mounted filesystem.

Merlin is an editor service that provides modern IDE features for OCaml. Emacs and Vim support is provided out-of-the-box. Since version 4.0, merlin's repository has a dedicated branch per version of OCaml, and the branch name consist of the concatenation of OCaml major version and minor version. So, for instance, OCaml 4.11.* maps to branch 411. The main branch is usually synchronized with the branch compatible with the latest (almost-)released version of OCaml. Note: if you're using an older version of OCaml (between 4.02 and 4.10) you will want to build the 3.4 branch, although it won't contain the most recent features. If you want to work on merlin, you'll want to avoid the -p merlin, to build in dev mode, with some extra warnings enabled. In that case you'll also need an extra dependency.

We are the world’s lightest blockchain, powered by participants. Using zero-knowledge technology, Mina is creating the infrastructure for the secure, democratic future we all deserve. Build on Mina with zkApps, smart contracts powered by zero-knowledge. The SDK, based on Typescript, will be available soon. The Mina blockchain remains ~22kb, enabling users to quickly and directly access the current state from their smartphone and other blockchains. Users today are compelled to hand over their data to centralized entities in order to participate in the modern world. But Mina’s zkApps, smart contracts powered by zero-knowledge, keep users in control of their privacy by validating and sharing proofs of their data, rather than the data itself. Think about getting a loan by simply sharing a proof of your personal ID and credit score, rather than the data itself. No risk of your personal information being hacked or sold. You are the only one owning your data, and it never leaves your device.
