Command line installer for gt

This repository hosts the installer served at:

• https://php.gt/install

The installer sets up a gt command for Linux and macOS shells using either native PHP with Composer or Docker.

Quick install:

• curl https://php.gt/install | sh

Verbose output:

• curl https://php.gt/install | sh -s -- --verbose

Force shell profile selection:

• curl https://php.gt/install | sh -s -- --shell bash

The gt command itself is implemented at PHP.GT/GtCommand and installed as the Composer package phpgt/gtcommand.

How the installer works

1. Preflight checks run before any prompts:
   • Native requirements: php >= 8.4, curl, and either archive support (unzip/7z/PHP zip) or git.
   • Docker availability (docker command).
2. If neither native nor Docker is viable, the installer explains missing requirements, suggests package-manager install commands, and links to:
   • https://php.gt/docs/installer/environments
3. If both paths are viable, the user chooses native or docker. If only one is viable, it is selected automatically.
4. The installer asks which shell profile to update (bash, zsh, sh), defaulting from:
   • --shell override, then parent-process inference, then $SHELL.
5. Native path:
   • Uses an existing composer executable if present; otherwise it offers to download composer-stable.phar.
   • Installs phpgt/gtcommand with composer global require.
6. Docker path:
   • Uses composer:2 container with mounted Composer home.
   • Installs phpgt/gtcommand in that mounted Composer home.
7. In both paths, the installer creates an executable launcher named gt in a writable bin directory:
   • It prefers /usr/local/bin, with a fallback to ~/.local/bin (or /tmp/.local/bin if HOME is unavailable).
8. If the launcher or Composer directory is not on PATH, the installer offers to append an export to the selected shell rc file.

Notes

• By default, the installer suppresses noisy command output and shows simple progress feedback for long steps.
• Use --verbose for full command logs.
• gt remains updatable through Composer (phpgt/gtcommand), while the installed launcher stays as the stable entry point.
