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