Rusty Prompt
Rusty Prompt is a command line interface builder based off of the go-prompt library.
Basic example:
use rusty_prompt::{App, Color, CommandState, Completer, Document, Executor, Prompt, PromptBuilder, Suggestion, Writer};
use rusty_prompt::colored_string::{ColoredChar, ColoredString};
pub struct Cli {}
impl Completer for Cli {
fn get_suggestions(&self, doc: Document) -> Vec<Suggestion> {
vec![
Suggestion::new("find", "Find something"),
Suggestion::new("go", "Go somewhere"),
Suggestion::new("die", "kills something"),
Suggestion::new("flame", "flames something"),
Suggestion::new("Blank_Desc", ""),
]
}
}
impl Executor for Cli {
fn execute(&mut self, command: &str, writer: &mut Writer) -> CommandState {
writer.write_str(&format!("Command: {}", command));
writer.write_str("\n");
CommandState::Ok
}
}
impl App for Cli {}
fn main() {
let chr = ColoredChar::builder().ch('>' as u8).foreground_color(Color::Yellow).build();
let prefix = ColoredString::new_from_inner(&[
chr, chr, chr,
ColoredChar::builder().ch(' ' as u8).build()
]);
let mut prompt: Prompt = PromptBuilder::builder().prefix(prefix).app(Box::new(Cli {})).build().into();
prompt.run();
}
Which will output a prompt:
