Open Source Source Code Analysis Tools

Hydrogen is an interactive coding environment that supports Python, R, JavaScript and other Jupyter kernels. Hydrogen was inspired by Bret Victor's ideas about the power of instantaneous feedback and the design of Light Table. Running code inline and in real-time is a more natural way to develop. By bringing the interactive style of Light Table to the rock-solid usability of Atom, Hydrogen makes it easy to write code the way you want to. You also may be interested in our latest project – interact – a desktop application that wraps up the best of the web-based Jupyter notebook. Watch expressions let you keep track of variables and re-run snippets after every change. Completions from the running kernel, just like autocomplete in the Chrome dev tools. Code can be inspected to show useful information provided by the running kernel. One kernel per language (so you can run snippets from several files, all in the same namespace).

Diff-ext is an extension for filemanagers such as Windows Explorer and Nautilus that allows to launch diff/merge tools on selected files.

Blocked is a source code editor that uses visual "blocks" to represent program structure

Currently in very early stages, but eventually plans to bring a code editor with extensive C++ auto completion and assistance.

EnDecode is a tool to decode/decompress parts of a binary file like PDF. If using PDF then stream to endstream data can be decompressed. You select from start to end of the part you want to decode and it will decode the data.

Walt is an alternative syntax for WebAssembly text format. It's an experiment for using JavaScript syntax to write to as 'close to the metal' as possible. It's JavaScript with rules. .walt files compile directly to WebAssembly binary format. Writing zero-overhead, optimized WebAssembly is pretty tough to do. The syntax for .wat files is terse and difficult to work with directly. If you do not wish to use a systems language like C or Rust, then you're kind of out of luck. Your best bet (currently) is to write very plain C code, compile that to .wast and then optimize that result. Then you're ready to compile that into the final WebAssembly binary. Provide a thin layer of syntax sugar on top of .wat text format. Preferably porting as much of JavaScript syntax to WebAssembly as possible. This improved syntax should give direct control over the WebAssembly output. Meaning there should be minimal to none post-optimization to be done to the waste code generated.
