    KSP

    KSP

    Kotlin Symbol Processing API

    KSP is Kotlin’s lightweight, idiomatic alternative to Java annotation processing that gives compile-time access to Kotlin program structure. Rather than forcing Kotlin through Java’s annotation APIs, it exposes Kotlin-first symbols—classes, functions, properties, types—so processors can generate code efficiently. The design dramatically reduces incremental build overhead by operating directly on symbols without compiling stubs, which speeds up large multi-module projects. Processors run as Gradle plugins, participate in incremental builds, and can target common use cases like DI bindings, JSON adapters, or UI glue code. Because the API reflects Kotlin semantics (nullability, visibility, type aliases, etc.), generated code aligns cleanly with Kotlin style and tooling.

    Lebab

    Lebab

    Turn your ES5 code into readable ES6

    Turn your ES5 code into readable ES6. Lebab does the opposite of what Babel does. Lebab transpiles your ES5 code to ES6/ES7. It does exactly the opposite of what Babel does. Convert your old-fashioned code using the lebab cli tool, enabling a specific transformation. The recommended way of using Lebab is to apply one transform at a time, read what exactly the transform does and what are its limitations, apply it to your code and inspect the diff carefully. Transforms can be applied with relatively high confidence. They use pretty straightforward and strict rules for changing the code. The resulting code should be almost 100% equivalent to the original code. Transforms should be applied with caution. They either use heuristics that can't guarantee that the resulting code is equivalent of the original code, or they have significant bugs which can result in breaking your code.

    Opal

    Opal

    Opal is a Ruby to JavaScript source-to-source compiler

    Opal is a Ruby to JavaScript source-to-source compiler. It comes packed with the Ruby corelib you know and love. It is both fast as a runtime and small in its footprint. The lib directory holds the Opal parser/compiler used to compile Ruby into JavaScript. It is also built ready for the browser into opal-parser.js to allow compilation in any JavaScript environment. This directory holds the Opal runtime and corelib implemented in Ruby and JavaScript. opal-parser allows you to eval Ruby code directly from your HTML (and from Opal) files without needing any other building process. Opal.compile is a simple interface to just compile a string of Ruby into a string of JavaScript code. See the website for more detailed instructions and guides for Rails, jQuery, Sinatra, rack, CDN, etc.

    ng-packagr

    ng-packagr

    Compile and package Angular libraries in Angular Package Format (APF)

    Compile and package Angular libraries in Angular Package Format (APF). Paths in the ngPackage section are resolved relative to the location of the package.json file. In the above example, public_api.ts is the entry file to the library's sources and must be placed next to package.json (a sibling in the same folder). You can easily run ng-package through a npm/yarn script. The build output is written to the dist folder, containing all those binaries to meet the Angular Package Format specification. You'll now be able to go ahead and npm publish dist your Angular library to the npm registry. Do you like to publish more libraries? Is your code living in a monorepo? Create one package.json per npm package, run ng-packagr for each! Creates scoped and non-scoped packages for publishing to npm registry. Inlines Templates and Stylesheets. Runs SCSS preprocessor, supporting the relative ~ import syntax and custom include paths.

    BSC

    BSC

    Bluespec Compiler (BSC)

    BSC is the open source compiler toolchain for Bluespec SystemVerilog, a high-level, rule-based hardware design language. It translates Bluespec descriptions into synthesizable Verilog, letting developers bring typed, modular abstractions into mainstream FPGA/ASIC flows. The compiler performs scheduling of atomic rules, elaborates parameterized modules, and enforces interface contracts, producing predictable RTL that integrates with existing EDA tools. A companion simulator enables fast functional execution and debugging before handing designs to traditional verification and synthesis stages. The ecosystem includes standard libraries, FIFOs, interfaces, and utilities that encourage reuse and clean separation of datapaths and control. By raising the abstraction for hardware architecture while preserving efficient output, BSC helps teams explore complex designs—such as RISC-V cores or accelerators—more productively.

    Clash

    Clash

    Haskell to VHDL/Verilog/SystemVerilog compiler

    Clash is a functional hardware description language that borrows both its syntax and semantics from the functional programming language Haskell. It provides a familiar structural design approach to both combinational and synchronous sequential circuits. The Clash compiler transforms these high-level descriptions to low-level synthesizable VHDL, Verilog, or SystemVerilog. Clash is an open-source project, licensed under the permissive BSD2 license, and actively maintained by QBayLogic. The Clash project is a Haskell Foundation affiliated project. Clash is built on Haskell which provides an excellent foundation for well-typed code. Together with Clash's standard library it is easy to build scalable and reusable hardware designs. Load your designs in an interpreter and easily test all your component without needing to setup a test bench. Although Clash offers many features, you sometimes need to directly access VHDL, Verilog, or SystemVerilog directly.

    Elm

    Elm

    Compiler for Elm, a functional language for reliable webapps

    Elm uses type inference to detect corner cases and give friendly hints. NoRedInk switched to Elm about four years ago, and 300k+ lines later, they still have not had to scramble to fix a confusing runtime exception in production. The compiler guides you safely through your changes, ensuring confidence even through the most wide-reaching refactorings in unfamiliar codebases. Including your own, six months later. All Elm programs are written in the same pattern, eliminating doubt and lengthy discussions when deciding how to build new projects and making it easy to navigate old or foreign codebases. Enjoy Elm's famously helpful error messages. Even on codebases with hundreds of thousands of lines of code, the compilation is done in a blink. Elm has its own virtual DOM implementation, designed for simplicity and speed. All values are immutable in Elm, and the benchmarks show that this helps us generate particularly fast JavaScript code.

    Type inference provides robustness and correctness, but without the cost of additional code. Let the compiler catch bugs for you. Fable produces readable JavaScript code compatible with ES2015 standards and popular tooling like Webpack. Call JavaScript from Fable or Fable from JS. Use NPM packages. The entire JavaScript ecosystem is at your fingertips. Choose your favorite tool, from Visual Studio Code to JetBrains Rider. Fable supports the F# core library and some common .NET libraries to supplement the JavaScript ecosystem. These are some of the main F# features that you can use in your web apps with Fable. There's a lot of code involving continuations out there, like asynchronous or indeterministic operations. Other languages bake specific solutions into the syntax, with F# you can use built-in computation expressions and also extend them yourself. These are some of the main F# features that you can use in your web apps with Fable.

    Google Closure Compiler

    Google Closure Compiler

    A JavaScript checker and optimizer

    Closure Compiler is a production-grade JavaScript optimizer and checker that parses JS, analyzes it, removes dead code, rewrites and minifies what remains, and emits faster, smaller bundles. Beyond minification, it performs advanced optimizations such as inlining, property collapsing, type-guided rewrites, and cross-module motion, often yielding substantial load-time wins. It includes a strong static checker that validates syntax, variable references, and type annotations (Closure types or JSDoc), catching bugs early and enabling aggressive transformations safely. The ecosystem provides a Java implementation, npm/JS builds, and documentation for integrating in modern toolchains. Closure Compiler has been used extensively at scale within Google and by the broader community, proving its robustness on very large codebases. Companion repositories track npm packaging and a JS-only variant for environments where running Java is undesirable.

    Hy

    Hy

    A dialect of Lisp that's embedded in Python

    Hy is a multi-paradigm general-purpose programming language in the Lisp family. It’s implemented as a kind of alternative syntax for Python. Compared to Python, Hy offers a variety of extra features, generalizations, and syntactic simplifications, as would be expected of a Lisp. Compared to other Lisps, Hy provides direct access to Python’s built-ins and third-party Python libraries, while allowing you to freely mix imperative, functional, and object-oriented styles of programming. The first thing a Python programmer will notice about Hy is that it has Lisp’s traditional parenthesis-heavy prefix syntax in place of Python’s C-like infix syntax. As in other Lisps, the value of a simplistic syntax is that it facilitates Lisp’s signature feature, metaprogramming through macros, which are functions that manipulate code objects at compile-time to produce new code objects, which are then executed as if they had been part of the original code.

    A refreshing programming language for the front-end web

    Mint has all the tools you need to write error-free, easily readable, and maintainable applications in record time. In Mint you can style elements directly with CSS using style blocks. Inside a style block, you can nest as many sub selectors and media queries as you like. Interpolate any Mint expressions in any value using the interpolation syntax. You can even use if and case expressions inside any block to apply styles conditionally. In Mint a store contains and manages some data. Stores are globally accessible and can be connected to components. When the data in a store changes the connected components are re-rendered. In Mint routing is a language feature instead of a library. Routes can be defined in a routes block, with support for typed path parameters. The runtime handles clicks on anchor tags and navigates in a smart way so you don't have to. You can inline any JavaScript code easily by using bacticks.

    PackageCompiler

    PackageCompiler

    Compile your Julia Package

    Julia is, in general, a "just-barely-ahead-of-time" compiled language. When you call a function for the first time, Julia compiles it for precisely the types of arguments given. This can take some time. All subsequent calls within that same session use this fast compiled function, but if you restart Julia you lose all the compiled work. PackageCompiler allows you to do this work upfront — further ahead of time — and store the results for a lower latency startup. You can save loaded packages and compiled functions into a file (called a sysimage) that you pass to Julia upon startup. Typically the goal is to reduce latency on your machine; for example, you could load the packages and compile the functions used in common plotting workflows using that saved image by default. In general, sysimages are not relocatable to other machines; they'll only work on the machine they were created on.
