In addition to upgrading the nightly build, I flattened the Stat struct
to embed the metadata fields. This simplified access to the values, but
needed a constructor method for ergonomic reasons.
In addition to upgrading to the nightly build, I refactored the method
that creates the directories by switching from a recursive approach to
an iterative one. I also replaced the obsolete fs::mkdir() with a custom
method using fs::create_dir() and libc::chmod(). I added several
diagnostic messages that match the GNU implementation.
I updated to the nightly build, completed support for the verbose flag,
and refactored the canonicalization method to simplify and add support
for Windows paths.
This commit updates `cut` to build on rust nightly.
In addition, it adds support for null input and output delimiters,
and fixes a bug in the `cut_characters()` function that would cause
incorrect output when two adjacent fields were specified in the range
list.
Aside from the usual upgrades to sync with the nightly build, I fixed an
unwrap() panic when reading lines with only a newline. I also refactored
the repeated command calls to use helper functions.
I created random data to test several cases. I verified that the data is
split into the correct number of files and can also be reassembled into
the original file.
The GNU implementation first strips all trailing slashes before deleting
the directory portion. This case wasn't handled.
I also rewrote the method that strips the directory to use the PathBuf
methods for improved platform-indepedence.
In addition, this commit brings the behavior of `rm` better in line
with the behavior of GNU Coreutils rm, especially as regarding recursive
interactive deletion of directories. This version asks to delete files
in a different order from GNU rm, but it now gives the option of stopping
the recursion at each new directory that is reached.
