smart_quotes

智能引号

这是一个提供简单启发式方法的微型辅助软件包，用于实现智能引号。

虽然这个软件包不转换任何符号，但它根据前一个字符提供启发式方法，判断下一个字符是否为开引号或闭引号。

示例用法

use smart_quotes::{decide_quote_after, Decision};

assert_eq!(decide_quote_after(None), Decision::Open);

assert_eq!(decide_quote_after(Some(' ')), Decision::Open);
assert_eq!(decide_quote_after(Some('\t')), Decision::Open);
assert_eq!(decide_quote_after(Some('\n')), Decision::Open);
assert_eq!(decide_quote_after(Some('\x0A')), Decision::Open);
assert_eq!(decide_quote_after(Some('\u{1680}')), Decision::Open);
assert_eq!(decide_quote_after(Some('\u{2005}')), Decision::Open);
assert_eq!(decide_quote_after(Some('\u{202F}')), Decision::Open);
assert_eq!(decide_quote_after(Some('\u{2029}')), Decision::Open);

assert_eq!(decide_quote_after(Some('(')), Decision::Open);
assert_eq!(decide_quote_after(Some('[')), Decision::Open);
assert_eq!(decide_quote_after(Some('{')), Decision::Open);
assert_eq!(decide_quote_after(Some('⟨')), Decision::Open);

assert_eq!(decide_quote_after(Some('\u{2012}')), Decision::Open);
assert_eq!(decide_quote_after(Some('\u{2015}')), Decision::Open);

assert_eq!(decide_quote_after(Some('x')), Decision::Close);
assert_eq!(decide_quote_after(Some('“')), Decision::Close);
assert_eq!(decide_quote_after(Some('‘')), Decision::Close);
assert_eq!(decide_quote_after(Some('.')), Decision::Close);
assert_eq!(decide_quote_after(Some(':')), Decision::Close);
