3 HISTORY - public release history for Data::Dumper
9 =item 2.121 (Aug 24 2003)
11 Backport to 5.6.1 by Ilya Martynov <ilya@martynov.org>.
13 =item 2.11 (unreleased)
15 C<0> is now dumped as such, not as C<'0'>.
17 qr// objects are now dumped correctly (provided a post-5.005_58)
20 Implemented $Data::Dumper::Maxdepth, which was on the Todo list.
21 Thanks to John Nolan <jpnolan@Op.Net>.
23 =item 2.101 (30 Apr 1999)
25 Minor release to sync with version in 5.005_03. Fixes dump of
28 =item 2.10 (31 Oct 1998)
30 Bugfixes for dumping related undef values, globs, and better double
31 quoting: three patches suggested by Gisle Aas <gisle@aas.no>.
33 Escaping of single quotes in the XS version could get tripped up
34 by the presence of nulls in the string. Fix suggested by
35 Slaven Rezic <eserte@cs.tu-berlin.de>.
37 Rather large scale reworking of the logic in how seen values
38 are stashed. Anonymous scalars that may be encountered while
39 traversing the structure are properly tracked, in case they become
40 used in data dumped in a later pass. There used to be a problem
41 with the previous logic that prevented such structures from being
44 Various additions to the testsuite.
46 =item 2.09 (9 July 1998)
48 Implement $Data::Dumper::Bless, suggested by Mark Daku <daku@nortel.ca>.
50 =item 2.081 (15 January 1998)
52 Minor release to fix Makefile.PL not accepting MakeMaker args.
54 =item 2.08 (7 December 1997)
56 Glob dumps don't output superflous 'undef' anymore.
58 Fixes from Gisle Aas <gisle@aas.no> to make Dumper() work with
59 overloaded strings in recent perls, and his new testsuite.
63 A separate flag to always quote hash keys (on by default).
65 Recreating known CODE refs is now better supported.
67 Changed flawed constant SCALAR bless workaround.
69 =item 2.07 (7 December 1996)
71 Dumpxs output is now exactly the same as Dump. It still doesn't
72 honor C<Useqq> though.
74 Regression tests test for identical output and C<eval>-ability.
76 Bug in *GLOB{THING} output fixed.
78 Other small enhancements.
80 =item 2.06 (2 December 1996)
82 Bugfix that was serious enough for new release--the bug cripples
83 MLDBM. Problem was "Attempt to modify readonly value..." failures
84 that stemmed for a misguided SvPV_force() instead of a SvPV().)
86 =item 2.05 (2 December 1996)
88 Fixed the type mismatch that was causing Dumpxs test to fail
91 GLOB elements are dumped now when C<Purity> is set (using the
94 The C<Freezer> option can be set to a method name to call
95 before probing objects for dumping. Some applications: objects with
96 external data, can re-bless themselves into a transitional package;
97 Objects the maintain ephemeral state (like open files) can put
98 additional information in the object to facilitate persistence.
100 The corresponding C<Toaster> option, if set, specifies
101 the method call that will revive the frozen object.
103 The C<Deepcopy> flag has been added to do just that.
105 Dumper does more aggressive cataloging of SCALARs encountered
106 within ARRAY/HASH structures. Thanks to Norman Gaywood
107 <norm@godel.une.edu.au> for reporting the problem.
109 Objects that C<overload> the '""' operator are now handled
110 properly by the C<Dump> method.
112 Significant additions to the testsuite.
116 =item 2.04beta (28 August 1996)
118 Made dump of glob names respect C<Useqq> setting.
120 [@$%] are now escaped now when in double quotes.
122 =item 2.03beta (26 August 1996)
124 Fixed Dumpxs. It was appending trailing nulls to globnames.
125 (reported by Randal Schwartz <merlyn@teleport.com>).
127 Calling the C<Indent()> method on a dumper object now correctly
128 resets the internal separator (reported by Curt Tilmes
129 <curt@ltpmail.gsfc.nasa.gov>).
131 New C<Terse> option to suppress the 'C<VARI<n> = >' prefix
132 introduced. If the option is set, they are output only when
133 absolutely essential.
135 The C<Useqq> flag is supported (but not by the XSUB version
138 Embedded nulls in keys are now handled properly by Dumpxs.
140 Dumper.xs now use various integer types in perl.h (should
141 make it compile without noises on 64 bit platforms, although
142 I haven't been able to test this).
144 All the dump methods now return a list of strings in a list
148 =item 2.02beta (13 April 1996)
150 Non portable sprintf usage in XS code fixed (thanks to
151 Ulrich Pfeifer <pfeifer@charly.informatik.uni-dortmund.de>).
154 =item 2.01beta (10 April 1996)
156 Minor bugfix (single digit numbers were always getting quoted).
159 =item 2.00beta (9 April 1996)
161 C<Dumpxs> is now the exact XSUB equivalent of C<Dump>. The XS version
166 MLDBM example removed (as its own module, it has a separate CPAN
169 Fixed bugs in handling keys with wierd characters. Perl can be
170 tripped up in its implicit quoting of the word before '=>'. The
171 fix: C<Data::Dumper::Purity>, when set, always triggers quotes
174 Andreas Koenig <k@anna.in-berlin.de> pointed out that handling octals
175 is busted. His patch added.
177 Dead code removed, other minor documentation fixes.
180 =item 1.23 (3 Dec 1995)
184 Several folks pointed out that quoting of ticks and backslashes
185 in strings is missing. Added.
187 Ian Phillipps <ian@pipex.net> pointed out that numerics may lose
188 precision without quotes. Fixed.
191 =item 1.21 (20 Nov 1995)
193 Last stable version I can remember.
