511 | --remove-duplicates => minimize duplicate email names/addresses |
512 | --roles => show roles (status:subsystem, git-signer, list, etc...) |
513 | --rolestats => show roles and statistics (commits/total_commits, %) |
514 | --file-emails => add email addresses found in -f file (default: 0 (off)) |
515 | --scm => print SCM tree(s) if any |
516 | --status => print status if any |
517 | --subsystem => print subsystem name if any |
518 | --web => print website(s) if any |
519 | |
520 | Output type options: |
521 | --separator [, ] => separator for multiple entries on 1 line |
522 | using --separator also sets --nomultiline if --separator is not [, ] |
523 | --multiline => print 1 entry per line |
524 | |
525 | Other options: |
526 | --pattern-depth => Number of pattern directory traversals (default: 0 (all)) |
527 | --keywords => scan patch for keywords (default: 1 (on)) |
528 | --sections => print the entire subsystem sections with pattern matches |
529 | --version => show version |
530 | --help => show this help information |
531 | |
532 | Default options: |
533 | [--email --git --m --n --l --multiline --pattern-depth=0 --remove-duplicates] |
534 | |
535 | Notes: |
536 | Using "-f directory" may give unexpected results: |
537 | Used with "--git", git signators for _all_ files in and below |
538 | directory are examined as git recurses directories. |
539 | Any specified X: (exclude) pattern matches are _not_ ignored. |
540 | Used with "--nogit", directory is used as a pattern match, |
541 | no individual file within the directory or subdirectory |
542 | is matched. |
543 | Used with "--git-blame", does not iterate all files in directory |
544 | Using "--git-blame" is slow and may add old committers and authors |
545 | that are no longer active maintainers to the output. |
546 | Using "--roles" or "--rolestats" with git send-email --cc-cmd or any |
547 | other automated tools that expect only ["name"] <email address> |
548 | may not work because of additional output after <email address>. |
549 | Using "--rolestats" and "--git-blame" shows the #/total=% commits, |
550 | not the percentage of the entire file authored. # of commits is |
551 | not a good measure of amount of code authored. 1 major commit may |
552 | contain a thousand lines, 5 trivial commits may modify a single line. |
553 | If git is not installed, but mercurial (hg) is installed and an .hg |
554 | repository exists, the following options apply to mercurial: |
555 | --git, |
556 | --git-min-signatures, --git-max-maintainers, --git-min-percent, and |
557 | --git-blame |
558 | Use --hg-since not --git-since to control date selection |
