sedregex

[发布文档]

[主文档]

一个简单的底层使用regex的sed-like库。

用法

基本上有两种公共接口供您使用

• find_and_replace，它对于一次性处理多个命令非常有用，
• 以及当您需要多次运行相同命令时，使用ReplaceCommand。

示例

让我们直接进入示例！

use sedregex::{find_and_replace, ReplaceCommand};
fn main() {
    // Both case-insensitive and global:
    assert_eq!(
        "Please stop wuts oh wut.",
        ReplaceCommand::new("s/lol/wut/ig").unwrap().execute("Please stop Lols oh lol."),
    );

    // Multiple commands in one go:
    assert_eq!(
        "Please stop nos oh no.",
        find_and_replace("Please stop Lols oh lol.", &["s/lol/wut/ig", "s/wut/no/g"]).unwrap()
    );

    // Same, but skipping the `s` character.
    assert_eq!(
        "Please stop wuts oh wut.",
        find_and_replace("Please stop Lols oh lol.", &["/lol/wut/ig"]).unwrap()
    );

    // Skipping the flags.
    assert_eq!(
        "Please stop Lols oh wut.",
        find_and_replace("Please stop Lols oh lol.", &["/lol/wut/"]).unwrap()
    );

    // Skipping the last slash.
    assert_eq!(
        "Please stop Lols oh wut.",
        find_and_replace("Please stop Lols oh lol.", &["/lol/wut"]).unwrap()
    );

    // Escaping a slash in a replace part.
    assert_eq!(
        r"Please stop wut/s oh wut/.",
        find_and_replace("Please stop Lols oh lol.", &[r"s/lol/wut\//gi"]).unwrap()
    );

    // Some regex stuff.
    // Also note the lack of the trailing slash: it's opitonal!
    assert_eq!(
        "Second, First",
        find_and_replace(
            "First, Second",
            &[r"s/(?P<first>[^,\s]+),\s+(?P<last>\S+)/$last, $first"],
        ).unwrap()
    );

    // Ok let's go with some simple regex stuff.
    assert_eq!(
        "Some weird typo",
        find_and_replace("Some wierd typo", &[r"s/ie/ei/"]).unwrap()
    );
}
