# Pi Extension Dev Tools and commands for developing and updating Pi extensions. ## Demo https://github.com/user-attachments/assets/44a96009-0653-4803-8590-d5a8a5131f4c Non sped-up version ## Installation ```bash pi install npm:@aliou/pi-extension-dev ``` Or from git: ```bash pi install git:github.com/aliou/pi-extension-dev ``` ## Commands ### `/extensions:update [VERSION]` Update Pi extensions to a target version. Without an argument, checks npm for the latest version and lets you choose between latest and installed. With a version argument, targets that version directly. Runs a guided workflow: detects the package manager, compares versions, reads changelogs and docs, analyzes source files for breaking changes, presents an update plan, and applies changes after confirmation. ## Tools ### `detect_package_manager` Detects the package manager used in the current project. Checks the `packageManager` field in `package.json` first, then falls back to lockfile detection (`pnpm-lock.yaml`, `yarn.lock`, `package-lock.json`, `bun.lockb`). Walks up from the working directory to the git root. Returns the package manager name, version (if declared), lockfile path, and install/run commands. ### `pi_version` Returns the version of the currently running Pi instance. ### `pi_docs` Lists all Pi documentation files from the Pi installation: `README.md`, individual files in `docs/`, and the `examples/` directory path. ### `pi_changelog` Parses the Pi changelog and returns entries for a specific version (or the latest). When the requested version is newer than the installed Pi, fetches the changelog from GitHub. ## Compatibility Compatible with Pi 0.50.x and 0.51.0+. Tools that need the extension context use a runtime shim to handle the execute signature difference between versions.
