Implementations

impl CommandParser

pub fn new() -> Self

Creates a new instance of CommandParser.

Example

let mut parser = cmd_parser::CommandParser::new();

pub fn insert(
    &mut self,
    name: &str,
    cmd: fn(_: Vec<&str>)
) -> Result<(), &'static str>

Adds a function to the system.

Example

fn echo(args: Vec<&str>) {
    println!("{}", args[1..].concat());
}

let mut parser = cmd_parser::CommandParser::new();
parser.insert("echo", echo);

pub fn call(&mut self, cmd: &str) -> Result<(), &'static str>

Calls a function with a command string.

Example

let mut parser = cmd_parser::CommandParser::new();
parser.insert("echo", |x| println!("{}", x[1..].concat()));

parser.call("echo This is an example!");

pub fn call_args(&mut self, cmd: Vec<&str>) -> Result<(), &'static str>

Calls a function with an array of components of the command.

Example

let mut parser = cmd_parser::CommandParser::new();
parser.insert("echo", |x| println!("{}", x[1..].concat()));

parser.call_args(vec!["echo", "This is an example"]);
