3 HISTORY - public release history for Data::Dumper
9 =item 2.09 (9 July 1998)
11 Implement $Data::Dumper::Bless, suggested by Mark Daku <daku@nortel.ca>.
13 =item 2.081 (15 January 1998)
15 Minor release to fix Makefile.PL not accepting MakeMaker args.
17 =item 2.08 (7 December 1997)
19 Glob dumps don't output superflous 'undef' anymore.
21 Fixes from Gisle Aas <gisle@aas.no> to make Dumper() work with
22 overloaded strings in recent perls, and his new testsuite.
26 A separate flag to always quote hash keys (on by default).
28 Recreating known CODE refs is now better supported.
30 Changed flawed constant SCALAR bless workaround.
32 =item 2.07 (7 December 1996)
34 Dumpxs output is now exactly the same as Dump. It still doesn't
35 honor C<Useqq> though.
37 Regression tests test for identical output and C<eval>-ability.
39 Bug in *GLOB{THING} output fixed.
41 Other small enhancements.
43 =item 2.06 (2 December 1996)
45 Bugfix that was serious enough for new release--the bug cripples
46 MLDBM. Problem was "Attempt to modify readonly value..." failures
47 that stemmed for a misguided SvPV_force() instead of a SvPV().)
49 =item 2.05 (2 December 1996)
51 Fixed the type mismatch that was causing Dumpxs test to fail
54 GLOB elements are dumped now when C<Purity> is set (using the
57 The C<Freezer> option can be set to a method name to call
58 before probing objects for dumping. Some applications: objects with
59 external data, can re-bless themselves into a transitional package;
60 Objects the maintain ephemeral state (like open files) can put
61 additional information in the object to facilitate persistence.
63 The corresponding C<Toaster> option, if set, specifies
64 the method call that will revive the frozen object.
66 The C<Deepcopy> flag has been added to do just that.
68 Dumper does more aggressive cataloging of SCALARs encountered
69 within ARRAY/HASH structures. Thanks to Norman Gaywood
70 <norm@godel.une.edu.au> for reporting the problem.
72 Objects that C<overload> the '""' operator are now handled
73 properly by the C<Dump> method.
75 Significant additions to the testsuite.
79 =item 2.04beta (28 August 1996)
81 Made dump of glob names respect C<Useqq> setting.
83 [@$%] are now escaped now when in double quotes.
85 =item 2.03beta (26 August 1996)
87 Fixed Dumpxs. It was appending trailing nulls to globnames.
88 (reported by Randal Schwartz <merlyn@teleport.com>).
90 Calling the C<Indent()> method on a dumper object now correctly
91 resets the internal separator (reported by Curt Tilmes
92 <curt@ltpmail.gsfc.nasa.gov>).
94 New C<Terse> option to suppress the 'C<VARI<n> = >' prefix
95 introduced. If the option is set, they are output only when
98 The C<Useqq> flag is supported (but not by the XSUB version
101 Embedded nulls in keys are now handled properly by Dumpxs.
103 Dumper.xs now use various integer types in perl.h (should
104 make it compile without noises on 64 bit platforms, although
105 I haven't been able to test this).
107 All the dump methods now return a list of strings in a list
111 =item 2.02beta (13 April 1996)
113 Non portable sprintf usage in XS code fixed (thanks to
114 Ulrich Pfeifer <pfeifer@charly.informatik.uni-dortmund.de>).
117 =item 2.01beta (10 April 1996)
119 Minor bugfix (single digit numbers were always getting quoted).
122 =item 2.00beta (9 April 1996)
124 C<Dumpxs> is now the exact XSUB equivalent of C<Dump>. The XS version
129 MLDBM example removed (as its own module, it has a separate CPAN
132 Fixed bugs in handling keys with wierd characters. Perl can be
133 tripped up in its implicit quoting of the word before '=>'. The
134 fix: C<Data::Dumper::Purity>, when set, always triggers quotes
137 Andreas Koenig <k@anna.in-berlin.de> pointed out that handling octals
138 is busted. His patch added.
140 Dead code removed, other minor documentation fixes.
143 =item 1.23 (3 Dec 1995)
147 Several folks pointed out that quoting of ticks and backslashes
148 in strings is missing. Added.
150 Ian Phillips <ian@pipex.net> pointed out that numerics may lose
151 precision without quotes. Fixed.
154 =item 1.21 (20 Nov 1995)
156 Last stable version I can remember.
