Rusty Prompt

Rusty Prompt 是基于 go-prompt 库的命令行界面构建工具。

基本示例

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();
}

将输出一个提示
