ggen-cli - Command-line interface for ggen code generation

This crate provides the command-line interface for ggen, using clap-noun-verb for automatic command discovery and routing. It bridges between user commands and the domain logic layer (ggen-domain).

Architecture

• Command Discovery: Uses clap-noun-verb v3.4.0 auto-discovery to find all \[verb\] functions in the cmds module
• Async/Sync Bridge: Provides runtime utilities to bridge async domain functions with synchronous CLI execution
• Conventions: File-based routing conventions for template-based command generation
• Node Integration: Programmatic entry point for Node.js addon integration

Features

• Auto-discovery: Commands are automatically discovered via clap-noun-verb
• Version handling: Built-in --version flag support
• Output capture: Programmatic execution with stdout/stderr capture
• Async support: Full async/await support for non-blocking operations

Examples

Basic CLI Execution

use ggen_cli_lib::cli_match;

# async fn example() -> ggen_core::utils::error::Result<()> {
// Execute CLI with auto-discovered commands
cli_match().await?;
# Ok(())
# }

Programmatic Execution

use ggen_cli_lib::run_for_node;

# async fn example() -> ggen_core::utils::error::Result<()> {
let args = vec!["template".to_string(), "generate".to_string()];
let result = run_for_node(args).await?;
println!("Exit code: {}", result.code);
println!("Output: {}", result.stdout);
# Ok(())
# }
