std.cli

Command-line interface utilities - argument parsing, terminal detection, and terminal size queries.

All functions are backed by the Rust runtime.

Functions

arg_count() -> Int

Returns the number of command-line arguments passed to the program (including the program name).

arg_get(index: Int) -> String

Returns the command-line argument at index. Index 0 is the program name.

is_terminal() -> Bool

Returns true if stdout is connected to a terminal (TTY).

terminal_width() -> Int

Returns the width (in columns) of the terminal. Returns 0 if not a terminal.

terminal_height() -> Int

Returns the height (in rows) of the terminal. Returns 0 if not a terminal.

Examples

load std.cli

fn main() -> Int:
    let argc = cli.arg_count()
    if argc > 1:
        let name = cli.arg_get(0)
        let arg1 = cli.arg_get(1)
    if cli.is_terminal():
        let w = cli.terminal_width()
        let h = cli.terminal_height()
    return 0
