* ls: Implement total size feature
- Implement total size reporting that was missing
- Fix minor formatting / readability nits
* tests: Add tests for ls total sizes feature
* ls: Fix MSRV build errors due to unsupported attributes for if blocks
* ls: Add windows support for total sizes feature
- Add windows support (defaults to file size as block sizes related
infromation is not avialable on windows)
- Renamed some functions
Add the `WordCountable::lines()` method that returns an iterator over
lines of a file-like object. This mirrors the
`std::io::BufRead::lines()` method, with some minor differences due to
the particular use case of `wc`.
This commit also creates a new module, `countable.rs`, to contain the
`WordCountable` trait and the new `Lines` struct returned by `lines()`.
Use clap for argument parsing instead of getopts
Also, make the following changes
* Use `executable!()` macro to output the name of utility
* Add another usage to help message
- Replace the parser with a recursive descent implementation that handles
parentheses and produces a stack of operations in postfix order.
Parsing now operates directly on OsStrings passed by the uucore framework.
- Replace the dispatch mechanism with a stack machine operating on the
symbol stack produced by the parser.
- Add tests for parenthesized expressions.
- Begin testing character encoding handling.
Moved argument parsing to clap and added tests to cover using "-" as
stdin, passing in too many file arguments, and updated the "wrap" error
message in the tests.
It is much faster to just write the lines to disk, separated by \n
(or \0 if zero-terminated is enabled), instead of serializing to json.
external_sort now knows of the Line struct instead of interacting with
it using the ExternallySortable trait. Similarly, it now uses the
crash_if_err! macro to handle errors, instead of bubbling them up.
Some functions were changed from taking &[Line] as the input to taking
an Iterator<Item = Line>. This removes the need to collect to a Vec
when not necessary.
