6 Log::Handler::Config - The main config loader.
7
9 use Log::Handler;
10 my $log = Log::Handler->new();
12 # Config::General
14 $log->config(config => 'file.conf');
15 # Config::Properties
17 $log->config(config => 'file.props');
18 # YAML
20 $log->config(config => 'file.yaml');
21 Or
23 use Log::Handler;
25 my $log = Log::Handler->new();
27 $log->config(
29 config => 'file.conf'
30 plugin => 'YAML',
31 );
32
34 This module makes it possible to load the configuration from a file.
35 The configuration type is determined by the file extension. It's also
36 possible to mix file extensions with another configuration types.
37
39 Plugin name File extensions
40 ------------------------------------------
41 Config::General cfg, conf
42 Config::Properties props, jcfg, jconf
43 YAML yml, yaml
44 If the extension is not defined then "Config::General" is used by
46 default.
47
49 config()
50 With this method it's possible to load the configuration for your
51 outputs.
52 The following options are valid:
54 config
56 With this option you can pass a file name or the configuration as a
57 hash reference.
58 $log->config(config => 'file.conf');
60 # or
61 $log->config(config => \%config);
62 plugin
64 With this option it's possible to say which plugin you want to use.
65 Maybe you want to use the file extension "conf" with "YAML", which
66 is reserved for the plugin "Config::General".
67 Examples:
69 # this would use Config::General
71 $log->config(
72 config => 'file.conf'
73 );
74 # this would force .conf with YAML
76 $log->config(
77 config => 'file.conf',
78 plugin => 'YAML'
79 );
80 section
82 If you want to write the configuration into a global configuration
83 file then you can create a own section for the logger:
84 <logger>
86 <file>
87 filename = file.log
88 minlevel = emerg
89 maxlevel = warning
90 </file>
91 <screen>
93 minlevel = emerg
94 maxlevel = debug
95 </screen>
96 </logger>
97 <another_script_config>
99 foo = bar
100 bar = baz
101 baz = foo
102 </another_script_config>
103 Now your configuration is placed in the "logger" section. You can
105 load this section with
106 $log->config(
108 config => 'file.conf',
109 section => 'logger',
110 );
111 # or if you load the configuration yourself to %config
113 $log->config(
115 config => \%config,
116 section => 'logger',
117 );
118 # or just
120 $log->config( config => $config{logger} );
122
124 Config::General - inspired by the well known apache config format
125 Config::Properties - Java-style property files
126 YAML - optimized for human readability
127
129 Config structures
130 A very simple configuration looks like:
131 $log->config(config => {
133 file => {
134 alias => 'file1',
135 filename => 'file1.log',
136 maxlevel => 'info',
137 minlevel => 'warn',
138 },
139 screen => {
140 alias => 'screen1',
141 maxlevel => 'debug',
142 minlevel => 'emerg',
143 }
144 });
145 Now, if you want to add another file-output then you can pass the
147 outputs with a array reference:
148 $log->config(config => {
150 file => [
151 {
152 alias => 'file1,
153 filename => 'file1.log',
154 maxlevel => 'info',
155 minlevel => 'warn',
156 },
157 {
158 alias => 'file2',
159 filename => 'file2.log',
160 maxlevel => 'error',
161 minlevel => 'emergency',
162 }
163 ],
164 screen => {
165 alias => 'screen1',
166 maxlevel => 'debug',
167 minlevel => 'emerg',
168 },
169 });
170 It's also possible to pass the outputs as a hash reference. The hash
172 keys "file1" and "file2" will be used as aliases.
173 $log->config(config => {
175 file => {
176 file1 => {
177 filename => 'file1.log',
178 maxlevel => 'info',
179 minlevel => 'warn',
180 },
181 file2 => {
182 filename => 'file2.log',
183 maxlevel => 'error',
184 minlevel => 'emergency',
185 }
186 },
187 screen => {
188 alias => 'screen1',
189 maxlevel => 'debug',
190 minlevel => 'emerg',
191 },
192 });
193 If you pass the configuration with the alias as a hash key then it's
195 also possible to pass a section called "default". The options from this
196 section will be used as defaults.
197 $log->config(config => {
199 file => {
200 default => { # defaults for all file-outputs
201 mode => 'append',
202 },
203 file1 => {
204 filename => 'file1.log',
205 maxlevel => 'info',
206 minlevel => 'warn',
207 },
208 file2 => {
209 filename => 'file2.log',
210 maxlevel => 'error',
211 minlevel => 'emergency',
212 }
213 },
214 screen => {
215 alias => 'screen1',
216 maxlevel => 'debug',
217 minlevel => 'emerg',
218 },
219 });
220 Examples for the config plugins

233 debug_mode = 2
234 filename = example.log
235 message_layout = '%T %H[%P] [%L] %S: %m'
236 </file>
237 Or
239 <file>
241 <file1>
242 fileopen = 1
