Mo: The Oxidized PHP Toolchain

• Main Topic: Introduction of Mo, a comprehensive toolchain for PHP inspired by the Rust ecosystem.
• Key Points:
  • Aims to be a comprehensive toolchain for PHP, drawing inspiration from the Rust ecosystem.
  • Significant portion of Mo is written in Rust.
  • Integrates linters, formatters, and static analysis tools into a single cohesive system.
  • Offers automated fixes to maintain a pristine codebase.
  • Provides consistent formatting, robust semantic checks, and abstract syntax tree visualization.
  • Aims to be a more integrated solution than existing PHP tools like PHP CSFixer and Psalm.
• Technical Terms: Oxidized, linter, formatter, static analysis, abstract syntax tree (AST).

GOVM: Your Sleek and Simple Go Version Manager

• Main Topic: Introduction of GOVM, a user-friendly tool for managing Go versions.
• Key Points:
  • Offers both a terminal user interface (TUI) and a command-line interface (CLI).
  • TUI allows effortless navigation and installation of Go versions using arrow keys.
  • CLI allows for quick operations like go install 1.21 or go use 1.20.
  • Simplifies the process of getting Go directly from go.dev.
  • Uses a shim approach for fast switching between installed versions without manual configuration.
  • Supports macOS and Linux.
• Technical Terms: Terminal User Interface (TUI), Command Line Interface (CLI), shim.

Nai: The Wayland Compositor that Rethinks Tiling

• Main Topic: Introduction of Nai, a Wayland compositor with a scrollable tiling approach.
• Key Points:
  • Rearranges application windows and columns on an infinite horizontal strip that can be scrolled through.
  • Opening a new window never causes existing windows to resize or shift unexpectedly.
  • Each connected monitor has its own completely separate window strip.
  • Dynamic workspaces are organized vertically, with each monitor having its own independent set.
  • Intelligently preserves workspace arrangements across disconnecting and reconnecting monitors.
  • Built from the ground up to properly separate monitors, unlike Gnome shell extensions like PaperWM.
• Technical Terms: Wayland compositor, tiling window manager.

Typescript Go: A Native Go Port of TypeScript

• Main Topic: Introduction of Typescript Go, a native port of the TypeScript language using Go.
• Key Points:
  • Aims to create a native port of the TypeScript language using the Go programming language.
  • Striving for a high degree of compatibility with existing TypeScript.
  • Achieved significant milestones including program creation, parsing/scanning, type resolution, and type checking.
  • Includes a prototype language service protocol (LSP).
  • Offers a distinct alternative to the traditional TypeScript toolchain.
• Technical Terms: Language Service Protocol (LSP).
