seahorse

A minimal CLI framework written in Rust

Using

toml [dependencies] seahorse = "0.4.0"

Example

Multiple action app

```rust use std::env; use seahorse::{ App, Action, Command, Context, Flag, FlagType, color };

fn main() { let args: Vec = env::args().collect(); let action: Action = |c: &Context| { let name = &c.args[2]; if c.bool_flag("bye") { println!("Bye, {}", name); } else { println!("Hello, {}", name); }

    match c.string_flag("other") {
        Some(val) => println!("{}", val),
        _ => println!("Not other...")
    }

    match c.int_flag("age") {
        Some(val) => println!("{} is {} years old", name, val),
        _ => println!("I don't know how old {} is...", name)
    }
};
let display_name = color::magenta("
 ██████╗██╗     ██╗
██╔════╝██║     ██║
██║     ██║     ██║
██║     ██║     ██║
╚██████╗███████╗██║
╚═════╝╚══════╝╚═╝");
let command = Command::new()
    .name("hello")
    .usage("cli_tool hello [name]")
    .action(action)
    .flags(vec![
        Flag::new("bye", "cli_tool hello [name] --bye", FlagType::Bool),
        Flag::new("other", "cli_tool hello [name] --other [string]", FlagType::String),
        Flag::new("age", "cli_tool hello [name] --age [int]", FlagType::Int),
    ]);

let app = App::new()
    .name("cli_tool")
    .display_name(display_name)
    .usage("cli_tool [command] [arg]")
    .version(env!("CARGO_PKG_VERSION"))
    .commands(vec![command]);

app.run(args);

} ```

bash $ cli_tool hello John --age 10 --other test Hello, John test John is 10 years old

Single action app

```rust use std::env; use seahorse::{SingleApp, Action, color, Context, Flag, FlagType};

fn main() { let args: Vec = env::args().collect(); let action: Action = |c: &Context| { let name = &c.args[0]; if c.boolflag("bye") { println!("Bye, {:?}", name); } else { println!("Hello, {:?}", name); } }; let displayname = color::magenta(" ██████╗██╗ ██╗ ██╔════╝██║ ██║ ██║ ██║ ██║ ██║ ██║ ██║ ╚██████╗███████╗██║ ╚═════╝╚══════╝╚═╝");

let app = SingleApp::new()
    .name("cli_tool")
    .display_name(display_name)
    .usage("cli_tool [args]")
    .version(env!("CARGO_PKG_VERSION"))
    .action(action)
    .flags(vec![
        Flag::new("bye", "cli_tool args --bye", FlagType::Bool),
    ]);

app.run(args);

} ```

```bash $ cli_tool John Hello, "John"

$ cli_tool John --bye Bye, "John" ```
