=head1 DESCRIPTION
|
|
|
|
|
|
35
|
|
|
|
|
|
|
36
|
Config::IniFiles provides a way to have readable configuration files outside
|
|
|
|
|
|
37
|
your Perl script. Configurations can be imported (inherited, stacked,...),
|
|
|
|
|
|
38
|
sections can be grouped, and settings can be accessed from a tied hash.
|
|
|
|

|
=head1 FILE FORMAT
|
|
|
|
|
|
41
|
|
|
|
|
|
|
42
|
INI files consist of a number of sections, each preceded with the
|
|
|
|
|
|
43
|
section name in square brackets, followed by parameter names and
|
|
|
|
|
|
44
|
their values.
|
|
|
|
|
|
45
|
|
|
|
|
|
|
46
|
[a section]
|
|
|
|
|
|
47
|
Parameter=Value
|
|
|
|
|
|
48
|
|
|
|
|
|
|
49
|
[section 2]
|
|
|
|
|
|
50
|
AnotherParameter=Some value
|
|
|
|
|
|
51
|
Setting=Something else
|
|
|
|
|
|
52
|
Parameter=Different scope than the one in the first section
|
|
|
|
|
|
53
|
|
|
|
|
|
|
54
|
The first non-blank character of the line indicating a section must
|
|
|
|
|
|
55
|
be a left bracket and the last non-blank character of a line indicating
|
|
|
|
|
|
56
|
a section must be a right bracket. The characters making up the section
|
|
|
|
|
|
57
|
name can be any symbols at all. However section names must be unique.
|
|
|
|
|
|
58
|
|
|
|
|
|
|
59
|
Parameters are specified in each section as Name=Value. Any spaces
|
|
|
|
|
|
60
|
around the equals sign will be ignored, and the value extends to the
|
|
|
|
|
|
61
|
end of the line (including any whitespace at the end of the line.
|
|
|
|
|
|
62
|
Parameter names are localized to the namespace of the section, but must
|
|
|
|
|
|
63
|
be unique within a section.
|
|
|
|
|
|
64
|
|
|
|
|
|
|
65
|
Both the hash mark (#) and the semicolon (;) are comment characters.
|
|
|
|
|
|
66
|
by default (this can be changed by configuration). Lines that begin with
|
|
|
|
|
|
67
|
either of these characters will be ignored. Any amount of whitespace may
|
|
|
|
|
|
68
|
precede the comment character.
|
|
|
|
|
|
69
|
|
|
|
|
|
|
70
|
Multi-line or multi-valued parameters may also be defined ala UNIX
|
|
|
|
|
|
71
|
"here document" syntax:
|
|
|
|
|
|
72
|
|
|
|
|
|
|
73
|
Parameter=<<EOT
|
|
|
|
|
|
74
|
value/line 1
|
|
|
|
|
|
75
|
value/line 2
|
|
|
|
|
|
76
|
EOT
|
|
|
|
|
|
77
|
|
|
|
|
|
|
78
|
You may use any string you want in place of "EOT". Note that whatever
|
|
|
|
|
|
79
|
follows the "<<" and what appears at the end of the text MUST match
|
|
|
|
|
|
80
|
exactly, including any trailing whitespace.
|
|
|
|
|
|
81
|
|
|
|
|
|
|
82
|
Alternately, as a configuration option (default is off), continuation
|
|
|
|
|
|
83
|
lines can be allowed:
|
|
|
|
|
|

=head1 USAGE -- Object Interface
|
|
|
|
|
|
92
|
|
|
|
|
|
|
93
|
Get a new Config::IniFiles object with the I<new> method:
|
|
|
|
|
|
94
|
|
|
|
|
|
|
95
|
$cfg = Config::IniFiles->new( -file => "/path/config_file.ini" );
|
|
|
|
|
|
96
|
$cfg = new Config::IniFiles -file => "/path/config_file.ini";
|
|
|
|
|
|
97
|
|
|
|
|
|
|
98
|
Optional named parameters may be specified after the configuration
|
|
|
|
|
|
99
|
file name. See the I<new> in the B<METHODS> section, below.
|
|
|
|
|
|
100
|
|
|
|
|
|
|
101
|
Values from the config file are fetched with the val method:
|
|
|
|
|
|
102
|
|
|
|
|
|
|
103
|
$value = $cfg->val('Section', 'Parameter');
|
|
|
|
|
|
104
|
|
|
|
|
|
|
105
|
If you want a multi-line/value field returned as an array, just
|
|
|
|
|
|
106
|
specify an array as the receiver:
|
|
|
|
|
|
107
|
|
|
|
|
|
|
108
|
@values = $cfg->val('Section', 'Parameter');

|
|
|
|
|
|
126

|
|
132
|
|
|
|
|
|
|
133
|
$cfg = Config::IniFiles->new( -file => STDIN );

|
|
|
|
|
|
142

|
|
|
|
|
|
|
145
|
5) an IO::File object
|
|
|
|
|
|
146
|
|
|
|
|
|
|
147
|
$io = IO::File->new( "/path/to/config_file.ini" );
|
|
|
|
|
|
148
|
$cfg = Config::IniFiles->new( -file => $io );
|
|
|
|
|
|
149
|
|
|
|
|
|
|
150
|
or
|
|
|
|
|
|
151
|
|
|
|
|
|
|
152
|
open my $fh, '<', "/path/to/config_file.ini" or die $!;

6) A reference to a scalar (requires newer versions of IO::Scalar)
|
|
|
|
|
|
156
|
|
|
|
|
|
|
157
|
$ini_file_contents = <<EOT
|
|
|
|
|
|
158
|
[section name]
|
|
|
|
|
|
159
|
Parameter=A value
|
|
|
|
|
|
160
|
Setting=Another value
|
|
|
|
|
|
161
|
EOT
|
|
|
|
|
|
162
|
|
|
|
|
|
|
163
|
$cfg = Config::IniFiles->new( -file => \$ini_file_contents );
|
|
|
|
|
|
164
|
|
|
|
|
|
|
165
|
|
|
|
|
|
|
166
|
If this option is not specified, (i.e. you are creating a config file from scratch)
|
|
|
|
|
|
167
|
you must specify a target file using L<SetFileName> in order to save the parameters.
|

=item I<-default> section
|
|
|
|
|
|
171
|
|
|
|
|
|
|
172
|
Specifies a section to be used for default values. For example, in the
|
|
|
|
|
|
173
|
following configuration file, if you look up the "permissions" parameter
|
|
|
|
|
|
174
|
in the "joe" section, there is none.
|
|
|
|
|
|
175
|
|
|
|
|
|
|
176
|
[all]
|
|
|
|
|
|
177
|
permissions=Nothing
|
|
|
|
|
|
178
|
|
|
|
|
|
|
179
|
[jane]
|
|
|
|
|
|
180
|
name=Jane
|
|
|
|
|
|
181
|
permissions=Open files
|
|
|
|
|
|
182
|
|
|
|
|
|
|
183
|
[joe]
|
|
|
|
|
|
184
|
name=Joseph
|
|
|
|
|
|
185
|
|
|
|
|
|
|
186
|
If you create your Config::IniFiles object with a default section of "all" like this:
|
|
|
|
|
|
187
|
|
|
|
|
|
|
188
|
$cfg = Config::IniFiles->new( -file => "file.ini", -default => "all" );
|
|
|
|
|
|
189
|
|
|
|
|
|
|
190
|
Then requsting a value for a "permissions" in the [joe] section will
|
|
|
|
|
|
191
|
check for a value from [all] before returning undef.
|
|
|
|
|
|
192
|
|
|
|
|
|
|
193
|
$permissions = $cfg->val( "joe", "permissions"); // returns "Nothing"
|
|
|
|
|
|
194
|
|
|
|
|
|
|
195
|
|
|
|
|
|
|
196
|
=item I<-fallback> section
|
|
|
|
|
|
197
|
|
|
|
|
|
|
198
|
Specifies a section to be used for parameters outside a section. Default is none.
|
|
|
|
|
|
199
|
Without -fallback specified (which is the default), reading a configuration file
|
|
|
|
|
|
200
|
which has a parameter outside a section will fail. With this set to, say,
|
|
|
|
|
|
201
|
"GENERAL", this configuration:
|
|
|
|
|
|
202
|
|
|
|
|
|
|
203
|
wrong=wronger
|
|
|

|
|
204

|
|
|
|
|
|
205
|
[joe]
|
|
|
|
|
|
206
|
name=Joseph
|
|
|
|
|
|
207
|
|
|
|
|
|
|
208
|
will be assumed as:
|
|
|
|
|
|
209
|
|
|
|
|
|
|
210
|
[GENERAL]
|
|
|
|
|
|
211
|
wrong=wronger
|
|
|
|
|
|
212
|
|
|
|
|
|
|
213

|
name=Joseph
|
|
|
|
|
|
215
|
|
|
|
|
|
|
216
|
Note that Config::IniFiles will also omit the fallback section header when
|
|
|
|
|
|
217
|
outputing such configuration.
|
|
|
|
|
|
218

=item I<-nocase> 0|1
|
|
|
|
|
|
220
|
|
|
|
|
|
|
221
|
Set -nocase => 1 to handle the config file in a case-insensitive
|
|
|
|
|
|
222
|
manner (case in values is preserved, however). By default, config
|
|
|
|
|
|
223
|
files are case-sensitive (i.e., a section named 'Test' is not the same
|
|
|
|
|
|
224
|
as a section named 'test'). Note that there is an added overhead for
|
|
|
|
|
|
225
|
turning off case sensitivity.
|
|
|
|
|
|
226
|
|

|
|
|
|
227
|
|
|

=item I<-import> object
|
|
|
|
|
|
229
|
|
|
|
|
|
|
230
|
This allows you to import or inherit existing setting from another
|
|
|
|
|
|
231
|
Config::IniFiles object. When importing settings from another object,
|
|
|
|
|
|
232
|
sections with the same name will be merged and parameters that are

value of given in the I<-file>.
|
|
|
|
|

235

|
If a I<-default> section is also given on this call, and it does not
|

|
|
|
237
|
coincide with the default of the imported object, the new default
|
|
|
|
|
|
238
|
section will be used instead. If no I<-default> section is given,
|
|
|
|
|
|
239
|
then the default of the imported object will be used.

|

244
|
Set -allowcontinue => 1 to enable continuation lines in the config file.
|
|
|
|
|
|
245
|
i.e. if a line ends with a backslash C<\>, then the following line is
|
|
|
|
|
|
246
|
appended to the parameter value, dropping the backslash and the newline
|
|
|
|
|
|
247
|
character(s).
|
|
|
|
|
|
248
|
|
|
|
|
|
|
249
|
Default behavior is to keep a trailing backslash C<\> as a parameter
|
|
|
|
|
|
250
|
value. Note that continuation cannot be mixed with the "here" value
|
|
|

an error.

If set to 0 (the default if not importing), these comments are treated

like ordinary ones.

|
|
|
|
276
|
|

277
|
The L</WriteConfig|WriteConfig(-delta=>1)> form will output such
|
|
|
|
|
|
278
|
comments to indicate deleted sections or parameters. This way,
|
|
|
|
|
|
279
|
reloading a delta file using the same imported object produces the
|
|
|
|
|
|
280
|
same results in memory again. See L<IMPORT / DELTA FEATURES> for more
|
|
|
|

|
|
|
|
|
|
284
|
|
|
|
|
|
|
285
|
The default comment character is C<#>. You may change this by specifying
|
|
|
|
|
|
286
|
this option to another character. This can be any character except
|
|
|
|
|
|
287
|
alphanumeric characters, square brackets or the "equal" sign.
|

|

|
|
|
|
|
|
291
|
|
|
|
|
|
|
292
|
Allowed default comment characters are C<#> and C<;>. By specifying this
|
|
|
|
|
|
293
|
option you may change the range of characters that are used to denote a
|
|
|
|
|
|
294
|
comment line to include any set of characters
|
|
|
|
|
|
295
|
|
|
|
|
|
|
296
|
Note: that the character specified by B<-commentchar> (see above) is
|
|
|
|
|
|
297
|
I<always> part of the allowed comment characters.

|
|
|

|
|
304
|
|

|
|
|
305
|
Set -reloadwarn => 1 to enable a warning message (output to STDERR)
|
|
|
|
|
|
306
|
whenever the config file is reloaded. The reload message is of the
|
|
|
|
|
|
307
|
form:
|
|
|
|
|
|
308
|
|
|
|
|
|
|
309
|
PID <PID> reloading config file <file> at YYYY.MM.DD HH:MM:SS
|
|
|
|
|
|
310
|
|
|
|
|
|
|
311
|
Default behavior is to not warn (i.e. -reloadwarn => 0).
|
|
|
|
|
|
312
|
|
|
|
|
|
|
313
|
This is generally only useful when using Config::IniFiles in a server
|
|
|
|
|
|
314
|
or daemon application. The application is still responsible for determining
|
|
|
|
|
|
315
|
when the object is to be reloaded.
|
|
|
|
|
|
316

|
|
|
|
|
|
319
|
|
|
|
|
|
|
320
|
Set -nomultiline => 1 to output multi-valued parameter as:
|
|
|
|
|
|
321
|
|
|
|
|
|
|
322
|
param=value1
|
|
|
|
|
|
323
|
param=value2
|
|
|
|
|
|
324
|
|
|
|
|
|
|
325
|
instead of the default:
|
|
|
|
|
|
326
|
|
|
|
|
|
|
327
|
param=<<EOT
|
|
|
|
|
|
328
|
value1
|
|
|
|
|
|
329
|
value2
|
|
|
|
|
|
330
|
EOT
|
|
|
|
|
|
331
|
|
|
|
|
|
|
332
|
As the later might not be compatible with all applications.

=item I<-handle_trailing_comment> 0|1
|
|
|
|
|
|
335
|
|
|
|
|
|
|
336
|
Set -handle_trailing_comment => 1 to enable support of parameter trailing
|
|
|
|
|
|
337
|
comments.
|
|
|
|
|
|
338
|
|
|
|
|
|
|
339
|
For example, if we have a parameter line like this:
|
|
|
|
|
|
340
|
|
|
|
|
|
|
341
|
param1=value1;comment1
|
|
|
|
|
|
342
|
|
|
|
|
|
|
343
|
by default, handle_trailing_comment will be set to B<0>, and we will get
|
|
|
|
|
|
344
|
I<value1;comment1> as the value of I<param1>. If we have
|
|
|
|
|
|
345
|
-handle_trailing_comment set to B<1>, then we will get I<value1>
|
|
|
|
|
|
346
|
as the value for I<param1>, and I<comment1> as the trailing comment of
|
|
|
|
|
|
347
|
I<param1>.
|
|
|
|
|
|
348
|
|
|
|
|
|
|
349
|
Set and get methods for trailing comments are provided as
|
|
|
|
|
|
350
|
L</SetParameterTrailingComment> and L</GetParameterTrailingComment>.

Writes out a new copy of the configuration file. A temporary file
|
|
|
|
|
|
1643
|
(ending in '-new') is written out and then renamed to the specified
|
|

|

filename. Also see B<BUGS> below.

If C<-delta> is set to a true value in %options, and this object was
|
|

1647
|
imported from another (see L</new>), only the differences between this
|
|
|
|
|
|
1648
|
object and the imported one will be recorded. Negative deltas will be
|
|
|
|
|
|
1649
|
encoded into comments, so that a subsequent invocation of I<new()>
|
|
|
|
|
|
1650
|
with the same imported object produces the same results (see the
|
|
|
|
|

1651

I<-negativedeltas> option in L</new>).

|

|
|
|
|
2355
|
|
|
|
|
|
|
2356
|
Using C<tie>, you can tie a hash to a B<Config::IniFiles> object. This creates a new
|
|
|
|
|
|
2357
|
object which you can access through your hash, so you use this instead of the
|
|
|
|
|
|
2358
|
B<new> method. This actually creates a hash of hashes to access the values in
|
|
|
|
|
|
2359
|
the INI file. The options you provide through C<tie> are the same as given for
|
|
|
|
|
|
2360
|
the B<new> method, above.
|
|
|
|
|
|
2361
|
|
|
|
|
|
|
2362
|
Here's an example:
|
|
|
|
|
|
2363
|
|
|
|
|
|
|
2364
|
use Config::IniFiles;
|
|
|
|
|
|
2365
|
|
|
|
|
|
|
2366
|
my %ini
|
|
|
|
|
|
2367
|
tie %ini, 'Config::IniFiles', ( -file => "/path/configfile.ini" );
|
|
|
|
|
|
2368
|
|
|
|
|
|
|
2369
|
print "We have $ini{Section}{Parameter}." if $ini{Section}{Parameter};
|
|
|
|
|
|
2370
|
|
|
|
|
|
|
2371
|
Accessing and using the hash works just like accessing a regular hash and
|
|
|
|
|
|
2372
|
many of the object methods are made available through the hash interface.
|
|
|
|
|
|
2373
|
|
|
|
|
|
|
2374
|
For those methods that do not coincide with the hash paradigm, you can use
|
|
|
|
|
|
2375
|
the Perl C<tied> function to get at the underlying object tied to the hash
|
|
|
|
|
|
2376
|
and call methods on that object. For example, to write the hash out to a new
|
|
|
|
|
|
2377
|
ini file, you would do something like this:
|
|
|
|
|
|
2378
|
|
|
|
|
|
|
2379
|
tied( %ini )->WriteConfig( "/newpath/newconfig.ini" ) ||
|
|
|
|
|
|
2380
|
die "Could not write settings to new file.";
|
|
|
|
|
|
2381
|
|
|
|
|
|
|
2382
|
=head2 $val = $ini{$section}{$parameter}
|
|
|
|
|
|
2383
|
|
|
|
|
|
|
2384
|
Returns the value of $parameter in $section.
|
|
|
|
|
|
2385
|
|
|
|
|
|
|
2386
|
Multiline values accessed through a hash will be returned
|
|
|
|
|
|
2387
|
as a list in list context and a concatenated value in scalar
|
|
|
|
|
|
2388
|
context.
|
|
|
|
|
|
2389
|
|
|
|
|
|
|
2390
|
=head2 $ini{$section}{$parameter} = $value;
|
|
|
|
|
|
2391
|
|
|
|
|
|
|
2392
|
Sets the value of C<$parameter> in C<$section> to C<$value>.
|
|
|
|
|
|
2393
|
|
|
|
|
|
|
2394
|
To set a multiline or multiv-alue parameter just assign an
|
|
|
|
|
|
2395
|
array reference to the hash entry, like this:
|
|
|
|
|
|
2396
|
|
|
|
|
|
|
2397
|
$ini{$section}{$parameter} = [$value1, $value2, ...];
|
|
|
|
|
|
2398
|
|
|
|
|
|
|
2399
|
If the parameter did not exist in the original file, it will
|
|
|
|
|
|
2400
|
be created. However, Perl does not seem to extend autovivification
|
|
|
|
|
|
2401
|
to tied hashes. That means that if you try to say
|
|
|
|
|
|
2402
|
|
|
|
|
|
|
2403
|
$ini{new_section}{new_paramters} = $val;
|
|
|
|
|
|
2404
|
|
|
|
|
|
|
2405
|
and the section 'new_section' does not exist, then Perl won't
|
|
|
|
|
|
2406
|
properly create it. In order to work around this you will need
|
|
|
|
|
|
2407
|
to create a hash reference in that section and then assign the
|
|
|
|
|
|
2408
|
parameter value. Something like this should do nicely:
|
|
|
|
|
|
2409
|
|
|
|
|
|
|
2410
|
$ini{new_section} = {};
|
|
|
|
|
|
2411
|
$ini{new_section}{new_paramters} = $val;
|
|
|
|
|
|
2412
|
|
|
|
|
|
|
2413
|
=head2 %hash = %{$ini{$section}}
|
|
|
|
|
|
2414
|
|
|
|
|
|
|
2415
|
Using the tie interface, you can copy whole sections of the
|
|
|
|
|
|
2416
|
ini file into another hash. Note that this makes a copy of
|
|
|
|
|
|
2417
|
the entire section. The new hash in no longer tied to the
|
|
|
|
|
|
2418
|
ini file, In particular, this means -default and -nocase
|
|
|
|
|
|
2419
|
settings will not apply to C<%hash>.
|
|
|
|
|
|
2420
|
|
|
|
|
|
|
2421
|
|
|
|
|
|
|
2422
|
=head2 $ini{$section} = {}; %{$ini{$section}} = %parameters;
|
|
|
|
|
|
2423
|
|
|
|
|
|
|
2424
|
Through the hash interface, you have the ability to replace
|
|
|
|
|
|
2425
|
the entire section with a new set of parameters. This call
|
|
|
|
|
|
2426
|
will fail, however, if the argument passed in NOT a hash
|
|
|
|
|
|
2427
|
reference. You must use both lines, as shown above so that
|
|
|
|
|
|
2428
|
Perl recognizes the section as a hash reference context
|
|
|
|
|
|
2429
|
before COPYing over the values from your C<%parameters> hash.
|
|
|
|
|
|
2430
|
|
|
|
|
|
|
2431
|
=head2 delete $ini{$section}{$parameter}
|
|
|
|
|
|
2432
|
|
|
|
|
|
|
2433
|
When tied to a hash, you can use the Perl C<delete> function
|
|
|
|
|
|
2434
|
to completely remove a parameter from a section.
|
|
|
|
|
|
2435
|
|
|
|
|
|
|
2436
|
=head2 delete $ini{$section}
|
|
|
|
|
|
2437
|
|
|
|
|
|
|
2438
|
The tied interface also allows you to delete an entire
|
|
|
|
|
|
2439
|
section from the ini file using the Perl C<delete> function.
|
|
|
|
|
|
2440
|
|
|
|
|
|
|
2441
|
=head2 %ini = ();
|
|
|
|
|
|
2442
|
|
|
|
|
|
|
2443
|
If you really want to delete B<all> the items in the ini file, this
|
|
|
|
|
|
2444
|
will do it. Of course, the changes won't be written to the actual
|
|
|
|
|
|
2445
|
file unless you call B<RewriteConfig> on the object tied to the hash.

When tied to a hash, you use the Perl C<keys> and C<each>
|
|
|
|
|
|
2460
|
functions to iteratively list the parameters (C<keys>) or
|
|
|
|
|
|
2461
|
parameters and their values (C<each>) in a given section.
|
|
|
|
|
|
2462
|
|
|
|
|
|
|
2463
|
You can also use the Perl C<exists> function to see if a
|
|
|
|
|
|
2464
|
parameter is defined in a given section.
|
|
|
|
|
|
2465
|
|
|
|
|
|
|
2466
|
Note that none of these will return parameter names that
|
|
|
|
|
|
2467
|
are part of the default section (if set), although accessing
|
|
|
|
|
|
2468
|
an unknown parameter in the specified section will return a
|
|
|
|
|
|
2469
|
value from the default section if there is one.

The I<-import> option to L</new> allows one to stack one
|
|
|
|
|
|
2902
|
I<Config::IniFiles> object on top of another (which might be itself
|
|
|
|
|
|
2903
|
stacked in turn and so on recursively, but this is beyond the
|
|
|
|
|
|
2904
|
point). The effect, as briefly explained in L</new>, is that the
|
|
|
|
|
|
2905
|
fields appearing in the composite object will be a superposition of
|
|
|
|
|
|
2906
|
those coming from the ``original'' one and the lines coming from the
|
|
|
|
|
|
2907
|
file, the latter taking precedence. For example, let's say that
|
|
|
|
|
|
2908
|
C<$master> and C<overlay> were created like this:
|
|
|
|
|
|
2909
|
|
|
|
|
|
|
2910
|
my $master = Config::IniFiles->new(-file => "master.ini");
|
|
|
|
|
|
2911
|
my $overlay = Config::IniFiles->new(-file => "overlay.ini",
|
|
|
|
|
|
2912
|
-import => $master);
|
|
|
|
|
|
2913
|
|
|
|
|
|
|
2914
|
If the contents of C<master.ini> and C<overlay.ini> are respectively
|
|
|
|
|
|
2915
|
|
|
|
|
|
|
2916
|
; master.ini
|
|
|
|
|
|
2917
|
[section1]
|
|
|
|
|
|
2918
|
arg0=unchanged from master.ini
|
|
|
|
|
|
2919
|
arg1=val1
|
|
|
|
|
|
2920
|
|
|
|
|
|
|
2921
|
[section2]
|
|
|
|
|
|
2922
|
arg2=val2
|
|
|
|
|
|
2923
|
|
|
|
|
|
|
2924
|
and
|
|
|
|
|
|
2925
|
|
|
|
|
|
|
2926
|
; overlay.ini
|
|
|
|
|
|
2927
|
[section1]
|
|
|
|
|
|
2928
|
arg1=overriden
|
|
|
|
|
|
2929
|
|
|
|
|
|
|
2930
|
Then C<< $overlay->val("section1", "arg1") >> is "overriden", while
|
|
|
|
|
|
2931
|
C<< $overlay->val("section1", "arg0") >> is "unchanged from
|
|
|
|
|
|
2932
|
master.ini".
|
|
|
|
|
|
2933
|
|
|
|
|
|
|
2934
|
This feature may be used to ship a ``global defaults'' configuration
|
|
|
|
|
|
2935
|
file for a Perl application, that can be overridden piecewise by a
|
|
|
|
|
|
2936
|
much shorter, per-site configuration file. Assuming UNIX-style path
|
|
|
|
|
|
2937
|
names, this would be done like this:
|
|
|
|
|
|
2938
|
|
|
|
|
|
|
2939
|
my $defaultconfig = Config::IniFiles->new
|
|
|
|
|
|
2940
|
(-file => "/usr/share/myapp/myapp.ini.default");
|
|
|
|
|
|
2941
|
my $config = Config::IniFiles->new
|
|
|
|
|
|
2942
|
(-file => "/etc/myapp.ini", -import => $defaultconfig);
|
|
|
|
|
|
2943
|
# Now use $config and forget about $defaultconfig in the rest of
|
|
|
|
|
|
2944
|
# the program
|
|
|
|
|
|
2945
|
|
|
|
|
|
|
2946
|
Starting with version 2.39, I<Config::IniFiles> also provides features
|
|
|
|
|
|
2947
|
to keep the importing / per-site configuration file small, by only
|
|
|
|
|
|
2948
|
saving those options that were modified by the running program. That
|
|
|
|
|
|
2949
|
is, if one calls
|
|
|
|
|
|
2950
|
|
|
|
|
|
|
2951
|
$overlay->setval("section1", "arg1", "anotherval");
|
|
|
|
|
|
2952
|
$overlay->newval("section3", "arg3", "val3");
|
|
|
|
|
|
2953
|
$overlay->WriteConfig(-delta=>1);
|
|
|
|
|
|
2954
|
|
|
|
|
|
|
2955
|
C<overlay.ini> would now contain
|
|
|
|
|
|
2956
|
|
|
|
|
|
|
2957
|
; overlay.ini
|
|
|
|
|
|
2958
|
[section1]
|
|
|
|
|
|
2959
|
arg1=anotherval
|
|
|
|
|
|
2960
|
|
|
|
|
|
|
2961
|
[section3]
|
|
|
|
|
|
2962
|
arg3=val3
|
|
|
|
|
|
2963
|
|
|
|
|
|
|
2964
|
This is called a I<delta file> (see L</WriteConfig>). The untouched
|
|
|
|
|
|
2965
|
[section2] and arg0 do not appear, and the config file is therefore
|
|
|
|
|
|
2966
|
shorter; while of course, reloading the configuration into C<$master>
|
|
|
|
|
|
2967
|
and C<$overlay>, either through C<< $overlay->ReadConfig() >> or through
|
|
|
|
|
|
2968
|
the same code as above (e.g. when application restarts), would yield
|
|
|
|
|
|
2969
|
exactly the same result had the overlay object been saved in whole to
|
|
|
|
|
|
2970
|
the file system.
|
|
|
|
|
|
2971
|
|
|
|
|
|
|
2972
|
The only problem with this delta technique is one cannot delete the
|
|
|
|
|
|
2973
|
default values in the overlay configuration file, only change
|
|
|
|
|
|
2974
|
them. This is solved by a file format extension, enabled by the
|
|
|
|
|
|
2975
|
I<-negativedeltas> option to L</new>: if, say, one would delete
|
|
|
|
|
|
2976
|
parameters like this,
|
|
|
|
|
|
2977
|
|
|
|
|
|
|
2978
|
$overlay->DeleteSection("section2");
|
|
|
|
|
|
2979
|
$overlay->delval("section1", "arg0");
|
|
|
|
|
|
2980
|
$overlay->WriteConfig(-delta=>1);
|
|
|
|
|
|
2981
|
|
|
|
|
|
|
2982
|
The I<overlay.ini> file would now read:
|
|
|
|
|
|
2983
|
|
|
|
|
|
|
2984
|
; overlay.ini
|
|
|
|
|
|
2985
|
[section1]
|
|
|
|
|
|
2986
|
; arg0 is deleted
|
|
|
|
|
|
2987
|
arg1=anotherval
|
|
|
|
|
|
2988
|
|
|
|
|
|
|
2989
|
; [section2] is deleted
|
|
|
|
|
|
2990
|
|
|
|
|
|
|
2991
|
[section3]
|
|
|
|
|
|
2992
|
arg3=val3
|
|
|
|
|
|
2993
|
|
|
|
|
|
|
2994
|
Assuming C<$overlay> was later re-read with C<< -negativedeltas => 1 >>,
|
|
|
|
|
|
2995
|
the parser would interpret the deletion comments to yield the correct
|
|
|
|
|
|
2996
|
result, that is, [section2] and arg0 would cease to exist in the
|
|
|
|
|
|
2997
|
C<$overlay> object.

Contains a list of errors encountered while parsing the configuration

file. If the I<new> method returns B<undef>, check the value of this
|
|

|
to find out what's wrong. This value is reset each time a config file

is read.

The output from [Re]WriteConfig/OutputConfig might not be as pretty as
|
|
|
|
|
|
3018
|
it can be. Comments are tied to whatever was immediately below them.
|
|
|
|
|
|
3019
|
And case is not preserved for Section and Parameter names if the -nocase
|
|
|
|
|
|
3020
|
option was used.

No locking is done by [Re]WriteConfig. When writing servers, take
|
|
|
|
|
|
3025

care that only the parent ever calls this, and consider making your
