Scan Dir

Documentation

Simple interface to iterate over files or subdirs of a directory

Features:

1. Ensure that file names are decodable to utf-8 (or error/warning is propagated)
2. Ignore hidden entries (by default)
3. Ignore common text editor and revision control backup files
4. Select only files or only directories
5. Simpler but detailed enough error handling
6. Recursive directory scanner

Here is the example:

use scan_dir::ScanDir;

ScanDir::dirs().read(".", |iter| {
    for (entry, name) in iter {
        println!("File {:?} has full path {:?}", name, entry.path());
    }
}).unwrap()

Compare it to stdlib way:

use std::fs::read_dir;
for entry_res in read_dir(".").unwrap() {
    let entry = entry_res.unwrap();
    let file_name_buf = entry.file_name();
    let file_name = file_name_buf.to_str().unwrap();
    if !file_name.starts_with(".") &&
        entry.file_type().unwrap().is_dir()
    {
        println!("File {:?} has full path {:?}",
            file_name, entry.path());
    }
}

Well, it looks almost fine until you want to turn unwrap's into correct error reporting.

Upgrading

The scan_dir 0.3 by default resolves symlink before checking if it's a file or directory. In the scan_dir 0.1-0.2 symlinks where always included in the list (i.e. they were skipped neither by skip_files nor by skip_dirs).
