sedregex

[Release docs]

[Master docs]

A simple sed-like library that uses regex under the hood.

Usage

There are basically two public interfaces which you can enjoy:

• [find_and_replace], which is useful for one-time processing of a bunch of commands,
• and [ReplaceCommand] when you need to run the same command multiple times.

Examples

Let's jump straight to the examples!

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()
    );
}
