Function is_git_installed 

pub fn is_git_installed() -> bool

Checks if Git is installed and accessible on the system.

This function verifies that the system’s git command is available in the PATH and responds to version queries. It’s a prerequisite check for all Git operations in AGPM.

Return Value

• true if Git is installed and responding to --version commands
• false if Git is not found, not in PATH, or not executable

Implementation Details

The function uses get_git_command() to determine the appropriate Git command for the current platform, then executes git --version to verify functionality.

Platform Differences

• Windows: Checks for git.exe, git.cmd, or git.bat in PATH
• Unix-like: Checks for git command in PATH
• All platforms: Respects PATH environment variable ordering

Examples

use agpm_cli::git::is_git_installed;

if is_git_installed() {
    println!("Git is available - proceeding with repository operations");
} else {
    eprintln!("Error: Git is not installed or not in PATH");
    std::process::exit(1);
}

Usage in AGPM

This function is typically called during:

• Application startup to validate prerequisites
• Before any Git operations to provide clear error messages
• In CI/CD pipelines to verify build environment

Alternative

For error-based validation with detailed context, use ensure_git_available():

use agpm_cli::git::ensure_git_available;

ensure_git_available()?; // Throws AgpmError::GitNotFound if not available
