A Rust implementation of MacOS's `open` command (`xdg-open`). It's written to be quickly and easily customizable, features separate local and global configs, and a zero-operand command allowing the user to specify how files should be opened differently, and for opening a project, etc.
I can use `open` to open the directory in Atom, or I could use `open src/main.rs` to open `main.rs` in Atom, and I can specify these on a per-project basis.
For directories with a local config, any missing values will be filled in by the global config (`~/.config/open.conf`), which means local configs can be shorter.
