5 | =head1 DESCRIPTION |
6 | |
7 | =over 8 |
8 | |
9 | =item 2.09 (9 July 1998) |
10 | |
11 | Implement $Data::Dumper::Bless, suggested by Mark Daku <daku@nortel.ca>. |
12 | |
13 | =item 2.081 (15 January 1998) |
14 | |
15 | Minor release to fix Makefile.PL not accepting MakeMaker args. |
16 | |
17 | =item 2.08 (7 December 1997) |
18 | |
19 | Glob dumps don't output superflous 'undef' anymore. |
20 | |
21 | Fixes from Gisle Aas <gisle@aas.no> to make Dumper() work with |
22 | overloaded strings in recent perls, and his new testsuite. |
23 | |
24 | require 5.004. |
25 | |
26 | A separate flag to always quote hash keys (on by default). |
27 | |
28 | Recreating known CODE refs is now better supported. |
29 | |
30 | Changed flawed constant SCALAR bless workaround. |
31 | |
32 | =item 2.07 (7 December 1996) |
33 | |
34 | Dumpxs output is now exactly the same as Dump. It still doesn't |
35 | honor C<Useqq> though. |
36 | |
37 | Regression tests test for identical output and C<eval>-ability. |
38 | |
39 | Bug in *GLOB{THING} output fixed. |
40 | |
41 | Other small enhancements. |
42 | |
43 | =item 2.06 (2 December 1996) |
44 | |
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().) |
48 | |
49 | =item 2.05 (2 December 1996) |
50 | |
51 | Fixed the type mismatch that was causing Dumpxs test to fail |
52 | on 64-bit platforms. |
53 | |
54 | GLOB elements are dumped now when C<Purity> is set (using the |
55 | *GLOB{THING} syntax). |
56 | |
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. |
62 | |
63 | The corresponding C<Toaster> option, if set, specifies |
64 | the method call that will revive the frozen object. |
65 | |
66 | The C<Deepcopy> flag has been added to do just that. |
67 | |
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. |
71 | |
72 | Objects that C<overload> the '""' operator are now handled |
73 | properly by the C<Dump> method. |
74 | |
75 | Significant additions to the testsuite. |
76 | |
77 | More documentation. |
78 | |
79 | =item 2.04beta (28 August 1996) |
80 | |
81 | Made dump of glob names respect C<Useqq> setting. |
82 | |
83 | [@$%] are now escaped now when in double quotes. |
84 | |
85 | =item 2.03beta (26 August 1996) |
86 | |
87 | Fixed Dumpxs. It was appending trailing nulls to globnames. |
88 | (reported by Randal Schwartz <merlyn@teleport.com>). |
89 | |
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>). |
93 | |
94 | New C<Terse> option to suppress the 'C<VARI<n> = >' prefix |
95 | introduced. If the option is set, they are output only when |
96 | absolutely essential. |
97 | |
98 | The C<Useqq> flag is supported (but not by the XSUB version |
99 | yet). |
100 | |
101 | Embedded nulls in keys are now handled properly by Dumpxs. |
102 | |
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). |
106 | |
107 | All the dump methods now return a list of strings in a list |
108 | context. |
109 | |
110 | |
111 | =item 2.02beta (13 April 1996) |
112 | |
113 | Non portable sprintf usage in XS code fixed (thanks to |
114 | Ulrich Pfeifer <pfeifer@charly.informatik.uni-dortmund.de>). |
115 | |
116 | |
117 | =item 2.01beta (10 April 1996) |
118 | |
119 | Minor bugfix (single digit numbers were always getting quoted). |
120 | |
121 | |
122 | =item 2.00beta (9 April 1996) |
123 | |
124 | C<Dumpxs> is now the exact XSUB equivalent of C<Dump>. The XS version |
125 | is 4-5 times faster. |
126 | |
127 | C<require 5.002>. |
128 | |
129 | MLDBM example removed (as its own module, it has a separate CPAN |
130 | reality now). |
131 | |
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 |
135 | around hash keys. |
136 | |
137 | Andreas Koenig <k@anna.in-berlin.de> pointed out that handling octals |
138 | is busted. His patch added. |
139 | |
140 | Dead code removed, other minor documentation fixes. |
141 | |
142 | |
143 | =item 1.23 (3 Dec 1995) |
144 | |
145 | MLDBM example added. |
146 | |
147 | Several folks pointed out that quoting of ticks and backslashes |
148 | in strings is missing. Added. |
149 | |
150 | Ian Phillips <ian@pipex.net> pointed out that numerics may lose |
151 | precision without quotes. Fixed. |
152 | |
153 | |
154 | =item 1.21 (20 Nov 1995) |
155 | |
156 | Last stable version I can remember. |
