linux-next/scripts/get_maintainer.pl
Joe Perches 683c6f8fcb scripts/get_maintainer.pl: improve --interactive UI
o Added searching by git-blame as well as git-history
o Added different selection toggles
o Added ability to list commits by author or by sign-off-type
o Use custom git and hg formats to make searching for subject/author
  a bit easier.
o Move inlined section matching and searching git/hg history to
  new get_maintainer subroutine
o Added subroutines save_commits_by_author and save_commits_by_signer
o Removed subroutines vcs_get_shortlog and vcs_email_shortlog
o Rename camelcase signaturePattern to signature_pattern

Update to 0.26 beta3

MAINTAINER field selection options:
--email => print email address(es) if any
--git => include recent git \*-by: signers
--git-all-signature-types => include signers regardless of signature type
or use only ${signature_pattern} signers (default: $email_git_all_signature_types)
--git-fallback => use git when no exact MAINTAINERS pattern (default: $email_git_fallback)
--git-chief-penguins => include ${penguin_chiefs}
--git-min-signatures => number of signatures required (default: $email_git_min_signatures)
--git-max-maintainers => maximum maintainers to add (default: $email_git_max_maintainers)
--git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
--git-blame => use git blame to find modified commits for patch or file
--git-since => git history to use (default: $email_git_since)
--hg-since => hg history to use (default: $email_hg_since)
--interactive => display a menu (mostly useful if used with the --git option)
--m => include maintainer(s) if any
--n => include name 'Full Name <addr\@domain.tld>'
--l => include list(s) if any
--s => include subscriber only list(s) if any
--remove-duplicates => minimize duplicate email names/addresses
--roles => show roles (status:subsystem, git-signer, list, etc...)
--rolestats => show roles and statistics (commits/total_commits, %)
--file-emails => add email addresses found in -f file (default: 0 (off))
--scm => print SCM tree(s) if any
--status => print status if any
--subsystem => print subsystem name if any
--web => print website(s) if any
Output type options:
--separator [, ] => separator for multiple entries on 1 line
using --separator also sets --nomultiline if --separator is not [, ]
--multiline => print 1 entry per line
Other options:
--pattern-depth => Number of pattern directory traversals (default: 0 (all))
--keywords => scan patch for keywords (default: 1 (on))
--sections => print the entire subsystem sections with pattern matches
--version => show version
--help => show this help information
Default options:
[--email --git --m --n --l --multiline --pattern-depth=0 --remove-duplicates]
Notes:
Using "-f directory" may give unexpected results:
Used with "--git", git signators for _all_ files in and below
directory are examined as git recurses directories.
Any specified X: (exclude) pattern matches are _not_ ignored.
Used with "--nogit", directory is used as a pattern match,
no individual file within the directory or subdirectory
is matched.
Used with "--git-blame", does not iterate all files in directory
Using "--git-blame" is slow and may add old committers and authors
that are no longer active maintainers to the output.
Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
other automated tools that expect only ["name"] <email address>
may not work because of additional output after <email address>.
Using "--rolestats" and "--git-blame" shows the #/total=% commits,
not the percentage of the entire file authored. # of commits is
not a good measure of amount of code authored. 1 major commit may
contain a thousand lines, 5 trivial commits may modify a single line.
If git is not installed, but mercurial (hg) is installed and an .hg
repository exists, the following options apply to mercurial:
--git,
--git-min-signatures, --git-max-maintainers, --git-min-percent, and
--git-blame
Use --hg-since not --git-since to control date selection
File ".get_maintainer.conf", if it exists in the linux kernel source root
directory, can change whatever get_maintainer defaults are desired.
Entries in this file can be any command line argument.
This file is prepended to any additional command line arguments.
Multiple lines and # comments are allowed.
