ack-v3.3.0

Changes for version v3.3.0

FEATURES
- The error message ack displays when the regex passed is invalid has been improved. The message is more readable and includes a pointer to the offending part of the regex. For example:
  - $ ack 'status: (open|closed|in progress' ack: Invalid regex 'status: (open|closed|in progress' Regex: status: (open|closed|in progress ^---HERE Unmatched ( in regex
- Added many new file and directory exclusions to speed up file selection.
- Python's *.pyc, *.pyd and *.pyo compiled files
- Python's __pycache__ and .pytest_cache directories
- Linux *.so shared object *.so files
- Windows dynamic-link library *.dll files
- gettext compiled *.mo translation files
- macOS's __MACOSX directories and .DS_Store files
- Reorganized the --help menu to put "action" options like -f, -g and -l at the top of the listing.
- The --show-types option only has an effect with -f or -g. ack will now tell you if you use --show-types without -f or -g when it will have no effect.
- Improved the error message when ack gets passed two options that can't be used together.
FIXES
- Fixed the behavior of --break and --heading. Using --break would implicitly set --noheading, and --heading would implicitly set --nobreak.
- The following pairs of options don't make sense to use together, and ack will now warn you if you try:
- -x and --files-from
- -v and -o
- -v and --output
- -v and --passthru
- Fixed the minimum version of the Getopt::Long module required. (GH #287)
- The line number and filename separators in --passthru mode now work the same as in context (-A/-B/-C) mode. (GH #291)
