SRC-DST-Clarifier

(WIP)

Give SRC and DST path, each may be a FILE or a DIR (even STDIO). Handle situations well and produce iterator over FILE-FILE pairs.

``` rust SrcDstConfig::new("png").parse("input.jpg", None); // [./input.jpg => ./A01123-0456-0789.png]

SrcDstConfig::new("png").parse("input.jpg", Some("output.jpg")); // [./input.jpg => ./output.jpg]

SrcDstConfig::new("png").parse("./frames", None); // [./frames/0001.jpg => ./A01123-0456-0789/0001.jpg] // [./frames/0002.jpg => ./A01123-0456-0789/0002.jpg] // [./frames/0003.jpg => ./A01123-0456-0789/0003.jpg] // ... // [./frames/xxxx.jpg => ./A01123-0456-0789/xxxx.jpg]

SrcDstConfig::new("png").parse("-", Some("-")); // [ => ] ```

See documentation on docs.rs.

TODOs

• Add wildcard matcher and (number) range filter to SRC.

  shell -i "./*.jpg" -i "./4???.jpg" -i "./{:04d}.jpg" -i "./{1..=999:04d}.jpg"
