Installation

pip install nil-clix

Usage

from nil_clix import create_node

node = create_node()

# Add flags
node.flag("verbose", "v", "Enable verbose output")

# Add parameters
node.param("config", "c", "Path to config file", fallback="config.yml")

# Add numbers
node.number("threads", "t", "Number of threads", fallback=4)

# Add handler
def handler(options):
    if options.flag("verbose"):
        print("Verbose mode enabled")
    config = options.param("config")
    threads = options.number("threads")
    print(f"Config: {config}, Threads: {threads}")
    return 0

node.use(handler)

# Run
exit_code = node.run(["-v", "-c", "my.yml", "-t", "8"])

Subcommands

from nil_clix import create_node

node = create_node()

def init_cmd(cmd):
    cmd.flag("force", "f", "Force initialization")

    def run_init(options):
        if options.flag("force"):
            print("Init: forced")
        else:
            print("Init: normal")
        return 0

    cmd.use(run_init)

node.sub("init", "Initialize the project", init_cmd)

exit_code = node.run(["init", "-f"])

Lifetime Notes

Root nodes are owning handles. The Python binding registers a GC finalizer so the underlying node is destroyed if the object is collected. Finalizer timing is nondeterministic and may not run at shutdown, so call destroy() for deterministic teardown. Subcommand nodes passed to callbacks are non-owning views and must not be stored or destroyed.
