11 | <h2><a name="log">Record</a></h2>
|
---|
12 | <h3>Description</h3>
|
---|
13 | <p>A recorder is a listener to the current build process that records the
|
---|
14 | output to a file.</p>
|
---|
15 |
|
---|
16 | <p>Several recorders can exist at the same time. Each recorder is
|
---|
17 | associated with a file. The filename is used as a unique identifier for
|
---|
18 | the recorders. The first call to the recorder task with an unused filename
|
---|
19 | will create a recorder (using the parameters provided) and add it to the
|
---|
20 | listeners of the build. All subsequent calls to the recorder task using
|
---|
21 | this filename will modify that recorders state (recording or not) or other
|
---|
22 | properties (like logging level).</p>
|
---|
23 |
|
---|
24 | <p>Some technical issues: the file's print stream is flushed for "finished"
|
---|
25 | events (buildFinished, targetFinished and taskFinished), and is closed on
|
---|
26 | a buildFinished event.</p>

75 | <h3>Examples</h3>
|
---|
76 | <p>The following build.xml snippet is an example of how to use the recorder
|
---|
77 | to record just the <code><javac></code> task:</p>
|
---|
78 | <pre>
|
---|
79 | ...
|
---|
80 | <compile >
|
---|
81 | <record name="log.txt" action="start"/>
|
---|
82 | <javac ...
|
---|
83 | <record name="log.txt" action="stop"/>
|
---|
84 | <compile/>
|
---|
85 | ...
|
---|
86 | </pre>
|
---|
87 |
|
---|
88 | <p>The following two calls to <code><record></code> set up two
|
---|
89 | recorders: one to file "records-simple.log" at logging level <code>info</code>
|
---|
90 | (the default) and one to file "ISO.log" using logging level of
|
---|
91 | <code>verbose</code>.</p>
|
---|
92 | <pre>
|
---|
93 | ...
|
---|
94 | <record name="records-simple.log"/>
|
---|
95 | <record name="ISO.log" loglevel="verbose"/>
|
---|
96 | ...
|
---|
97 | </pre>
|
---|

99 | <h3>Notes</h3>
|
---|
100 | <p>There is some functionality that I would like to be able to add in the
|
---|
101 | future. They include things like the following:</p>

107 | </tr>
|
---|
108 | <tr>
|
---|
109 | <td valign="top">listener</td>
|

130 | <code>includetarget="compile" exlcudetask="javac"</code>, what should
