- 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.
This removes the need to allocate a new string for each line when used
with -f, -d or -i. Instead, a custom string comparison algorithm takes
care of these cases.
The resulting performance improvement is about 20% per flag (i.e. there
is a 60% improvement when combining all three flags)
As a side-effect, the size of the Line struct was reduced from 96 to 80
bytes, reducing the overhead for each line.
* ls: added creation time
* ls: Added most time features
Missing support for posix-,Format+, translating via locales. Also required more tests
* ls: rustfmt
* ls: Additional changes and fixes
Fixed the argument order, fixed a wrong iso format.
* ls: additional tests for styles
* ls: perfected arg parsing on time styles
* fix birthime test
* ls: Use 'stdout_str' in new tests
* ls: Disabled birthtime test for windows
* ls: removed indoc as a dependency
* ls: birthime test, sync first created file
* ls: birthime test, add comment explaining sync
* Removed ruby testfile birth_test.rb
This accidentally got commited in a merge
