* ls: Implement --zero flag. (#2929) This flag can be used to provide a easy machine parseable output from ls, as discussed in the GNU bug report https://debbugs.gnu.org/cgi/bugreport.cgi?bug=49716. There are some peculiarities with this flag: - Current implementation of GNU ls of the `--zero` flag implies some other flags. Those can be overridden by setting those flags after `--zero` in the command line. - This flag is not compatible with `--dired`. This patch is not 100% compliant with GNU ls: GNU ls `--zero` will fail if `--dired` and `-l` are set, while with this patch only `--dired` is needed for the command to fail. We also add `--dired` flag to the parser, with no additional behaviour change. Testing done: ``` $ bash util/build-gnu.sh [...] $ bash util/run-gnu-test.sh tests/ls/zero-option.sh [...] PASS: tests/ls/zero-option.sh ============================================================================ Testsuite summary for GNU coreutils 9.1.36-8ec11 ============================================================================ # TOTAL: 1 # PASS: 1 # SKIP: 0 # XFAIL: 0 # FAIL: 0 # XPASS: 0 # ERROR: 0 ============================================================================ ``` * Use the US way to spell Behavior * Fix formatting with cargo fmt -- tests/by-util/test_ls.rs * Simplify --zero flag overriding logic by using index_of Also, allow multiple --zero flags, as this is possible with GNU ls command. Only the last one is taken into account. Co-authored-by: Sylvestre Ledru <sledru@mozilla.com> |
