Crate normpath

source ·
Expand description

This crate provides methods to normalize paths in the recommended way for the operating system.

It was made to fix a recurring bug caused by using fs::canonicalize on Windows: #45067, #48249, #52440, #55812, #58613, #59107, #74327. Normalization is usually a better choice unless you specifically need a canonical path.

Using these replacement methods will usually fix those issues, but see their documentation for more information:

Additionally, these methods can be used for other enhancements:

Features

These features are optional and can be enabled or disabled in a “Cargo.toml” file.

Optional Features

Implementation

All traits are sealed, meaning that they can only be implemented by this crate. Otherwise, backward compatibility would be more difficult to maintain for new features.

Sponsorship

If this crate has been useful for your project, let me know with a sponsorship! Sponsorships help me create and maintain my open source libraries, and they are always very appreciated.

Examples

use std::io;
use std::path::Path;

use normpath::BasePathBuf;
use normpath::PathExt;

fn find_target_dir(path: &Path) -> io::Result<Option<BasePathBuf>> {
    let mut path = path.normalize()?;
    while !path.ends_with("target") {
        match path.pop() {
            Ok(true) => continue,
            Ok(false) => {}
            Err(_) => {
                eprintln!("Some components could not be normalized.");
            }
        }
        return Ok(None);
    }
    Ok(Some(path))
}
