multi-char separator with overlap Fix a bug in `tac` where multi-character line separators would cause incorrect behavior when there was overlap between candidate matches in the input string. This commit adds a dependency on `memchr` in order to use the `memchr::memmem::rfind_iter()` function to scan for non-overlapping instances of the specified line separator characters, scanning from right to left.

Try `uucat somefile | wc -c`. + +### Counting lines + +In the case of `wc -l` or `wc -cl` the input doesn't have to be decoded. It's read in chunks and the `bytecount` crate is used to count the newlines. + +It's useful to vary the line length in the input. GNU wc seems particularly bad at short lines. + +### Processing unicode + +This is the most general strategy, and it's necessary for counting words, characters, and line lengths. Individual steps are still switched on and off depending on what must be reported. + +Try varying which of the `-w`, `-m`, `-l` and `-L` flags are used. (The `-c` flag is unlikely to make a difference.) + +Passing no flags is equivalent to passing `-wcl`. That case should perhaps be given special attention as it's the default. + +## Generating files + +To generate a file with many very short lines, run `yes | head -c50000000 > 25Mshortlines`. + +To get a file with less artificial contents, download a book from Project Gutenberg and concatenate it a lot of times: + +``` +wget https://www.gutenberg.org/files/2701/2701-0.txt -O moby.txt +cat moby.txt moby.txt moby.txt moby.txt > moby4.txt +cat moby4.txt moby4.txt moby4.txt moby4.txt > moby16.txt +cat moby16.txt moby16.txt moby16.txt moby16.txt > moby64.txt +``` + +And get one with lots of unicode too: + +``` +wget https://www.gutenberg.org/files/30613/30613-0.txt -O odyssey.txt +cat odyssey.txt odyssey.txt odyssey.txt odyssey.txt > odyssey4.txt +cat odyssey4.txt odyssey4.txt odyssey4.txt odyssey4.txt > odyssey16.txt +cat odyssey16.txt odyssey16.txt odyssey16.txt odyssey16.txt > odyssey64.txt +cat odyssey64.txt odyssey64.txt odyssey64.txt odyssey64.txt > odyssey256.txt +``` + +Finally, it's interesting to try a binary file.

Fixed that one clippy warning. * Moved the cfg not windows up to the function level because this function is meant to only run in non-windows OS (with groups and unames).

The origin of the problem was that `handle_obsolete` was not looking for named signals but only for numbers preceded by '-'. I have made a few changes: - Change `handle_obsolete` to use `signal_by_name_or_value` to parse the possible signal. - Since now the signal is already parsed return an `Option` instead of `Option<&str>` to parse later. - Change the way to decide the pid to use from a `match` to a `if` because the tested element are actually not the same for each branch. - Parse the signal from the `-s` argument outside of `kill` function for consistency with the "obsolete" signal case. - Again for consistency, parse the pids outside the `kill` function. --- src/uu/kill/src/kill.rs | 99 ++++++++++++++++++++--------------------- 1 file changed, 49 insertions(+), 50 deletions(-) diff --git a/src/uu/kill/src/kill.rs b/src/uu/kill/src/kill.rs index 494dc0602..f269f7283 100644 --- a/src/uu/kill/src/kill.rs +++ b/src/uu/kill/src/kill.rs @@ -15,7 +15,7 @@ use libc::{c_int, pid_t}; use std::io::Error; use uucore::display::Quotable; use uucore::error::{UResult, USimpleError}; -use uucore::signals::ALL_SIGNALS; +use uucore::signals::{signal_by_name_or_value, ALL_SIGNALS}; use uucore::InvalidEncodingHandling; static ABOUT: &str = "Send signal to processes or list information about signals."; @@ -37,10 +37,10 @@ pub enum Mode { #[uucore_procs::gen_uumain] pub fn uumain(args: impl uucore::Args) -> UResult<()> { - let args = args + let mut args = args .collect_str(InvalidEncodingHandling::Ignore) .accept_any(); - let (args, obs_signal) = handle_obsolete(args); + let obs_signal = handle_obsolete(&mut args); let usage = format!("{} [OPTIONS]...

Specifically, before this change, the `done_printing()` function was called twice on each iteration of the main loop. After this change, it is only called once per iteration. Furthermore, this change makes the `print_seq()` function similar in structure to the `print_seq_integers()` function.
