    Filtrex

    Filtrex

    A simple, safe, JavaScript Filter Expression compiler for end-users

    Filtrex is a simple and safe JavaScript expression compiler designed for end-user input. It lets users write spreadsheet-like filter expressions without giving them access to raw JavaScript execution. Instead of using eval, Filtrex compiles expressions into JavaScript functions while keeping data access and callable functions under developer control. It supports common use cases such as filtering items, searching across fields, colorizing records, plotting charts, and building browser-based spreadsheet behavior. The expression language supports numbers, strings, external variables, arithmetic, comparisons, regular expression matching, and logical operations. Overall, it gives applications a safer way to let users define dynamic rules and filters.

    Hogan.js

    Hogan.js

    A compiler for the Mustache templating language

    Hogan.js is a 2.5k JS templating engine developed at Twitter. Use it as a part of your asset packager to compile templates ahead of time or include it in your browser to handle dynamic templates. If you're developing with Node.js, just use NPM to add the Hogan package. Hogan.js was developed against the mustache test suite, so everything that holds true for templates is also the case for hogan.js. That means you get variables, sections, lambdas, partials, filters, and everything else you've come to expect from mustache templating, only much, much faster. Use hogan.compile() to precompile your templates into vanilla JS. It's best to serve your templates precompiled whenever you can (rather than the raw templates), as parsing is the most time consuming operation. Once compiled, call the render() method with a context and optional partials object. If supplying partials, you can compile them ahead of time, or pass string templates.

    Ino-L

    Simple programming language for Windows.

    Ino-L is a TUI programming language for Windows that compiles into MS-DOS batch files. Ino-L stands for Innova Language, because Innova is French for innovation. The purpose of the language is to allow programmers the same functionality and abilities of batch files, but with simpler syntax and limited GUI, along with other things MS-DOS does not natively support. Your MS-DOS code can also be incorporated into the Ino-L source code, along with JavaScript and VisualBasic.

    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.

    Rollup

    Rollup

    A module bundler for JavaScript

    Rollup is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. It uses the new standardized format for code modules included in the ES6 revision of JavaScript, instead of previous idiosyncratic solutions such as CommonJS and AMD. ES modules let you freely and seamlessly combine the most useful individual functions from your favorite libraries. This will eventually be possible natively everywhere, but Rollup lets you do it today. Rollup can be used either through a command line interface with an optional configuration file, or else through its JavaScript API. Rollup allows you to write your code using the new module system, and will then compile it back down to existing supported formats such as CommonJS modules, AMD modules, and IIFE-style scripts. This means that you get to write future-proof code.

    Schism

    Schism

    A self-hosting Scheme to WebAssembly compiler

    Schism is an experimental compiler that translates Scheme programs into WebAssembly, allowing Scheme code to execute in both browser environments and server platforms like Node.js. Developed initially by Google researchers, the project was designed to explore the intersection of functional programming and WebAssembly’s low-level efficiency. Schism supports a subset of the R6RS Scheme standard and is self-hosting, meaning that the compiler itself is written in and compiled by Schism. Its architecture demonstrates advanced compiler design techniques such as staged compilation and snapshot-based bootstrapping. The project focuses on leveraging WebAssembly’s experimental capabilities, including reference types and tail calls, to test the limits of language portability and runtime performance. Though no longer actively maintained, Schism remains a valuable example of how high-level languages can be mapped to WebAssembly and offers insights into language implementation.
