Installation Logic

Version Checking

1. Check Current Version: Detects installed Tea CLI version
2. Fetch Latest: Gets latest version from Gitea API
3. Compare Versions: Only proceeds if newer version available
4. Force Override: --force flag bypasses version check

Installation Priority

1. Package Manager (preferred):

   • Debian/Ubuntu: Checks for official Tea CLI package
   • RHEL/CentOS/Fedora: Checks for available Tea CLI package
   • Arch Linux: Available in AUR (pacman)
   • openSUSE: Checks for available Tea CLI package

2. Binary Download (fallback):

   • Downloads platform-specific binary from Gitea releases
   • Supports x86_64, ARM64, ARM architectures
   • Installs to /usr/local/bin/tea

File Locations

Installation Directory

• Binary: /usr/local/bin/tea
• Symlink: /usr/local/bin/tea-<version>

Version Comparison

The installer uses semantic version comparison:

• Format: vX.Y.Z (e.g., v0.11.1)
• Logic: Compares major, minor, patch versions
• Build Info: Ignores build hashes/identifiers

Examples

# Current: 0.11.0, Latest: v0.11.1 → Update needed
# Current: 0.11.1, Latest: v0.11.1 → No update needed
# Current: 0.11.2, Latest: v0.11.1 → No update needed (newer installed)

System Requirements

Required

• curl or wget (for downloading)
• sudo access (for system-wide installation)

Optional

• Package manager access (for package installations)
• Internet connection (for downloading releases)

Supported Distributions

Package Manager Support

• Debian/Ubuntu: Checks for official Tea CLI package
• RHEL/CentOS/Fedora: Checks for available Tea CLI package
• Arch Linux: Available in AUR (pacman)
• openSUSE: Checks for available Tea CLI package

Binary Support

• Linux x86_64: tea-0.11.1-linux-amd64
• Linux ARM64: tea-0.11.1-linux-arm64
• Linux ARM: tea-0.11.1-linux-arm-5, tea-0.11.1-linux-arm-6, tea-0.11.1-linux-arm-7

Troubleshooting

Version Detection Issues

# Check current version manually
tea --version

# Force reinstall if version detection fails
./install-tea-cli.sh --force

Permission Issues

# Ensure proper permissions
sudo chown root:root /usr/local/bin/tea
sudo chmod 755 /usr/local/bin/tea

PATH Issues

# Check which tea is being used
which tea

# Check all tea installations
find /usr -name tea 2>/dev/null
find /home -name tea 2>/dev/null

# Update PATH if needed
export PATH="/usr/local/bin:$PATH"

Examples

Typical Workflow

# Check if update needed
./install-tea-cli.sh

# Output if up-to-date:
# [SUCCESS] You already have the latest version (0.11.1)
# [SUCCESS] No installation needed. Exiting.

# Output if update available:
# [INFO] Current version: 0.11.0
# [INFO] Latest version: v0.11.1
# [INFO] Newer version available: v0.11.1 > 0.11.0
# [SUCCESS] Installation completed successfully!

Force Binary Installation

# Force binary installation
./install-tea-cli.sh --force --binary

# Output:
# [SUCCESS] Tea CLI binary installed successfully
# Next steps:
# 1. Test installation: tea --version
# 2. Configure login: tea login add
# 3. Use Tea CLI: tea --help

Integration with Setup Script

The Tea CLI installer is automatically integrated with the main Git repository setup script:

1. Detection: Checks for existing Tea CLI installations
2. Offer Installation: Prompts to install Tea CLI if none found
3. Configuration: Guides through login setup
4. Repository Management: Enables Gitea repository operations

Security Features

• Official Releases: Downloads from official Gitea releases
• Package Verification: Uses official package repositories
• Proper Permissions: Sets appropriate file ownership and permissions

Contributing

To add support for new distributions or architectures:

1. Update detect_os() function for new package managers
2. Add architecture detection in get_arch() function
3. Update installation methods in install_tea_from_*() functions
4. Test with target distribution
5. Update documentation
