cx-terminfo

cx-terminfo 是一个几乎纯 Rust 的库，用于解析 terminfo 文件。无需其他 Rust 依赖。

用法

将此添加到您的 'Cargo.toml' 中

[dependencies]
cxterminfo = "*"

或者

[dependencies]
cxterminfo = { git = "https://github.com/bxinom/cx-terminfo" }

并将此添加到您的 crate 根目录

extern crate cxterminfo;

示例

加载默认的 terminfo 数据库

use cxterminfo::terminfo;

fn main() {
    if Ok(info) = terminfo::from_env() {
        // do whatever you want
    }
}

标准功能

cx-terminfo 为功能提供了三个枚举（每个值都有文档说明）

cxterminfo::capabilities::BoolCapability // known bool capabilities
cxterminfo::capabilities::NumberCapability // known number capabilities
cxterminfo::capabilities::StringCapability // known string capabilities

如何获取功能值

use cxterminfo::terminfo;
use cxterminfo::capabilities::{BoolCapability, NumberCapability, StringCapability};

fn main() {
    if Ok(info) = terminfo::from_env() {
        println!("{:?}", info.get_bool(BoolCapability::AutoLeftMargin));
        println!("{:?}", info.get_number(NumberCapability::MaxColors));
        println!("{:?}", info.get_string(StringCapability::Bell));
    }
}

扩展功能

use cxterminfo::terminfo;

fn main() {
    if Ok(info) = terminfo::from_env() {
        println!("{:?}", info.get_ext_bool("AT"));
        println!("{:?}", info.get_ext_number("IDENT"));
        println!("{:?}", info.get_ext_string("XM"));
    }
}

参数化字符串

use cxterminfo::param_string::{evaluate, Param};

fn main() {
    // Move cursor to location 10, 10
    let param_str = "\x1B[%d;%dH";
    if let Ok(move_cursor) = evaluate(param_str, &[Param::Number(10), Param::Number(10)]) {
        println!("{:?}", move_cursor);
    }
}

终端响应

要处理响应，请使用 sscanf 实现。
