History file for ack 3.  https://beyondgrep.com/


v3.1.1      Sat Aug 31 22:56:10 CDT 2019
========================================
[SPEEDUP]
Improved the speed up the -l, -L and -c options by pre-scanning the file
in bulk before doing line-by-line scan. (GH #221)

[FIXES]
On Windows, patterns with $ to mark the end of the line would not match.
(GH #229)

[DOCUMENTATION]
Fixed docs that referred to --range-stop instead of --range-end. (GH #228)

[INTERNALS]
Now requires File::Next 1.18.


v3.1.0      Thu Aug 22 22:43:15 CDT 2019
========================================
[FEATURES]
Added the --range-start and --range-end options to allow searching only
ranges of each file. (GH #165)


v3.0.3      Tue Aug 20 23:42:02 CDT 2019
========================================
[FIXES]
Made smartcase's check for lowercase patterns smarter.

[DOCUMENTATION]
Updated many URLs, especially in the config. (GH #223)


v3.0.2      Thu Jul  4 21:42:43 CDT 2019
========================================
[FIXES]
ack's smart-case feature would think that a pattern like "select \S+ from"
is looking for a uppercase letter, and so would not make a case-insensitive
search.  Now, ack knows that uppercase letters in metacharacters don't
count as looking for a uppercase letter. (GH #156, 187, 214)


v3.0.1      Tue Jun 25 20:47:58 CDT 2019
========================================
[FIXES]
The -s option tells ack not to complain about missing or unreadable files
it tries to search.  The -s option would not always work in conjection with
the -x option.  Now it does.  Thanks, Anders Eriksson and M. Scott Ford.
(GH #175)

ack would die if you specified a --output option that didn't use one
of Perl's special match variables.  Now it won't.  Thanks, M. Scott
Ford. (GH #210)

[INTERNALS]
Added a Dockerfile for use when working on ack development.  Thanks,
M. Scott Ford. (GH #208)


v3.0.0      Mon May 27 21:46:34 CDT 2019
========================================
First official release of ack verison 3.

See "Release notes for ack 3.0.0" at the bottom of this document for
details of what has changed between ack 2.x and ack 3.

[FIXES]
Fixed a failing test if Pod::Perldoc::ToTextOverstrike was being
used. (GH#202)


2.999_08 Sun May 19 20:33:13 CDT 2019
=====================================
[ENHANCEMENTS]
Consolidated the manual and FAQ into one document, accessible with --man.
Cookbook.pm has been moved to dev for future use.

Added SVG filetype.

[FIXES]
Invalid options used to cause an error message triplicate. Fixes GH #192.


2.999_07 Sun Mar 31 21:54:55 CDT 2019
=====================================
[ENHANCEMENTS]
Added --help-colors and --help-rgb-colors options to display colors
available for color options.

Many more mutex options have been added to help users know when they've
made a mistake.  For example, it doesn't make sense to have -C to show
context when using -f to get a file list.

Overhauled the handling of mutually exclusive options.  We now properly
handle mutex options even if they are abbreviated.  The actual argument
used is now shown.  Fixes GH #57.


2.999_06 Thu Jan 10 20:37:23 CST 2019
=====================================
[ENHANCEMENTS]
The --tt option for Template Toolkit is now --ttml.  The short version
still works.

The standalone version of ack no longer supports the --faq or --cookbook
options, which never worked right for it anyway.  Instead, --man includes
the FAQ and Cookbook.

The --man option no longer uses the `perldoc` program for rendering the
documentation.  This means you'll have to pipe it into your own pager if
you want scrolling, but it makes it much more portable.

[FIXES]
ack would stop finding files if there was a file named "0" in the current
directory. Thanks, Rob Hoelz. (GH #162)

[REMOVED FUNCTIONALITY]
The --lines option has been removed. (GH #167)

The -u short alias for --underline has been removed. (GH #173)


2.999_05 Sun Oct 21 21:37:39 CDT 2018
=====================================
[ENHANCEMENTS]
Add -p as a shorter version of --proximate.


2.999_04 Thu Sep  6 17:45:07 CDT 2018
=====================================
[ENHANCEMENTS]
Added -P as a negation of --proximate.  It is the same as --proximate=0.
If you have --proximate in an .ackrc, -P can be used to cancel it.

Added --ts for Typescript.


2.999_03 Fri Jan 19 11:02:46 CST 2018
=====================================
[ENHANCEMENTS]
The check for whether we need to scan the entire file line-by-line now
reads 10M of file instead of just 100K.

Removed support for the ACK_OPTIONS environment variable.  Use an ackrc
file instead.  If you have ACK_OPTIONS set, ack will give a warning.

Lots of internal speedups.


2.999_02 Mon Jan  8 23:03:42 CST 2018
=====================================
[ENHANCEMENTS]
Added an optimization to make ack only do a line-by-line search of a
file if there's a match somewhere in the file.  This gives ack a 20-30%
in timings of common cases.


2.999_01 Mon Jan  1 22:11:17 CST 2018
=====================================
[ENHANCEMENTS]
Added --pod as a filetype, recognizing .pod as its extension.  This is
Perl's POD (Plain Old Documentation) format.

Added --markdown as a filetype, recognizing .md and .markdown as
extensions.

--pager is no longer allowed in a project .ackrc file.  --match and
--output are not allowed in any .ackrc file.

ack 3's new features are listed below for now.

[FIXES]
--lines had some mutex options that were not getting checked.  Now,
--lines is mutex with --passthru, --match and all context options.


=============================
# Release notes for ack 3.0.0
=============================

# New features

ack 3 is a greplike tool optimized for searching large code trees.

Improvements over ack 2 include:

* Improved `-w` option.

* `-w` option will warn if your pattern does not lend itself to
word matching.

* `-i`, `-I` and `--smart-case`

* `--proximate=N` option

* Added `--pod` and `--markdown`.

* Added `GNUmakefile` to the list of makefile specs.

* Added `-S` as a synonym for `--smart-case`.

# Bug fixes

* Column numbers were not getting colorized in the output.  Added
`--color-colno` option and `ACK_COLOR_COLNO` environment variable.

* A pattern that wanted whitespace at the end could match the
linefeed at the end of a line.  This is no longer possible.

# Incompatibilities with ack 2

## ack 3 requires Perl 5.10.1

ack 2 only needed Perl 5.8.8.  This shouldn't be a problem since 5.10.1
has been out since 2009.

## ack 3 no longer highlights capture groups.

ack 2 would highlight your capture groups.  For example,

    ack '(set|get)_foo_(name|id)'

would highlight the `set` or `get`, and the `name` or `id`, but not the
full `set_user_id` that was matched.

This feature was too confusing and has been removed.  Now, the entire
matching string is highlighted.

## ack 3's --output allows fewer special variables

In ack 2, you could put any kind of Perl code in the `--output`
option and it would get `eval`uated at run time, which would let
you do tricky stuff like this gem from Mark Fowler
(http://www.perladvent.org/2014/2014-12-21.html):

    ack --output='$&: @{[ eval "use LWP::Simple; 1" && length LWP::Simple::get($&) ]} bytes' \
                    'https?://\S+' list.txt
    http://google.com/: 19529 bytes
    http://metacpan.org/: 7560 bytes
    http://www.perladvent.org/: 5562 bytes

This has been a security problem in the past, and so in ack 3 we
no longer `eval` the contents of `--output`.  You're now restricted
to the following variables: `$1` thru `$9`, `$_`, `$.`, `$&`, ``$` ``,
`$'` and `$+`.  You can also embed `\t`, `\n` and `\r` ,
and `$f` as stand-in for `$filename` in `ack2 --output` .
