    Delta

    Delta

    A viewer for git and diff output

    Code evolves, and we all spend time studying diffs. Delta aims to make this both efficient and enjoyable: it allows you to make extensive changes to the layout and styling of diffs, as well as allowing you to stay arbitrarily close to the default git/diff output. Language syntax highlighting with color themes. Within-line highlights based on a Levenshtein edit inference algorithm. Git style strings (foreground color, background color, font attributes) are supported for >20 stylable elements....

    PHP Parser

    PHP Parser

    A PHP parser written in PHP

    ...As the parser is based on the tokens returned by token_get_all (which is only able to lex the PHP version it runs on), additionally a wrapper for emulating tokens from newer versions is provided. This allows to parse PHP 7.4 source code running on PHP 7.0, for example. This emulation is somewhat hacky and not perfect, but it should work well on any sane code. Support for pretty printing, which is the act of converting an AST into PHP code. Please note that "pretty printing" does not imply that the output is especially pretty.

    BadUSB

    BadUSB

    Flipper Zero badusb payload library

    This project explores USB device emulation attacks—commonly called BadUSB—by demonstrating how commodity USB hardware can impersonate keyboards, network adapters, or storage devices to perform scripted actions on a host. It typically contains firmware examples, payloads, and explanations showing how a device presenting as a Human Interface Device (HID) can inject keystrokes, open shells, or orchestrate data exfiltration when plugged into a machine.

    .NET version of the Playwright testing and automation library

    ...Test on Windows, Linux, and macOS, locally or on CI, headless or headed. Cross-language. Use the Playwright API in TypeScript, JavaScript, Python, .NET, Java. Test Mobile Web. Native mobile emulation of Google Chrome for Android and Mobile Safari. The same rendering engine works on your Desktop and in the Cloud. Auto-wait. Playwright waits for elements to be actionable prior to performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts - the primary cause of flaky tests.

    Emacs-libvterm

    Emacs libvterm integration

    ...Because it uses compiled libvterm code, it can support full-screen terminal applications, interactive shells, TUI programs, and complex terminal behavior more reliably. The project bridges Emacs Lisp with native terminal emulation so users can keep command-line workflows inside Emacs without losing too much terminal compatibility. It is especially useful for developers who live in Emacs and want to run tools such as shells, editors, REPLs, and terminal dashboards in the same environment. Its main value is bringing modern terminal performance and fidelity into the Emacs workflow.
