<h2><a name="log">Recorder</a></h2>
<h3>Description</h3>
<p>A recorder is a listener to the current build process that records the
output to a file.

<p>Several recorders can exist at the same time. Each recorder is
associated with a file. The filename is used as a unique identifier for
the recorders. The first call to the recorder task with an unused filename
will create a recorder (using the parameters provided) and add it to the
listeners of the build. All subsiquent calls to the recorder task using
this filename will modify that recorders state (recording or not) or other
properties (like logging level).

<p>Some technical issues: the file's print stream is flushed for "finished"
events (buildFinished, targetFinished and taskFinished), and is closed on
a buildFinished event.

<h3>Parameters</h3>
<table border="1" cellpadding="2" cellspacing="0">
<tr>
<td valign="top"><b>Attribute</b></td>
<td valign="top"><b>Description</b></td>
<td align="center" valign="top"><b>Required</b></td>
</tr>
<tr>
<td valign="top">name</td>
<td valign="top">The name of the file this logger is associated with.</td>
<td align="center" valign="middle">yes</td>
</tr>
<tr>
<td valign="top">action</td>
<td valign="top">This tells the logger what to do: should it start
recording or stop? The first time that the recorder task is called for
this logfile, and if this attribute is not provided, then the default
for this attribute is "start". If this attribute is not provided on
subsiquest calls, then the state remains as previous.
[Values = {start|stop}, Default = no state change]</td>
<td align="center" valign="middle">no</td>
</tr>
<tr>
<td valign="top">append</td>
<td valign="top">Should the recorder append to a file, or create a new
one? This is only applicable the first time this task is called for
this file. [Vaules = {yes|no}, Default=yes]</td>
<td align="center" valign="middle">no</td>
</tr>
<tr>
<td valign="top">loglevel</td>
<td valign="top">At what logging level should this recorder instance
record to? This is not a once only parameter (like <code>append</code>
is) -- you can increase or decrease the logging level as the build process
continues. [Vaules= {error|warn|info|verbose|debug}, Default = no change]
</td>
<td align="center" valign="middle">no</td>
</tr>
</table>

<h3>Examples</h3>
<p>The following build.xml snippit is an example of how to use the recorder
to record just the <code>&lt;javac&gt;</code> task:
<pre>
...
&lt;compile &gt;
&lt;recorder name="log.txt" action="start" /&gt;
&lt;javac ...
&lt;recorder name="log.txt" action="stop" /&gt;
&lt;compile/&gt;
...
</pre>

<p>The following two calls to <code>&lt;recorder&gt;</code> set up two
recorders: one to file "records-simple.log" at logging level <code>info</code>
(the default) and one to file "ISO.log" using logging level of
<code>verbose</code>.
<pre>
...
&lt;recorder name="records-simple.log" /&gt;
&lt;recorder name="ISO.log" loglevel="verbose" /&gt;
...
</pre>

<h3>Notes</h3>
<p>There is some funtionality that I would like to be able to add in the
future. They include things like the following:
<table border="1" cellpadding="2" cellspacing="0">
<tr>
<td valign="top"><b>Attribute</b></td>
<td valign="top"><b>Description</b></td>
<td align="center" valign="top"><b>Required</b></td>
</tr>
<tr>
<td valign="top">messageprefix</td>
<td valign="top">Whether or not to include the message prefixes (things
like the name of the tasks or targets, etc). This has the same effect as
the <code>-emacs</code> command line parameter does to the screen output.
[yes|no]</td>
<td align="center" valign="middle">no</td>
</tr>
<tr>
<td valign="top">listener</td>
<td valign="top">A classname of a build listener to use from this point
on instead of the default listener.</td>
<td align="center" valign="middle">no</td>
</tr>
<tr>
<td valign="top">includetarget</td>
<td valign="top" rowspan=2>A comma-separated list of targets to automaticly
record. If this value is "all", then all targets are recorded.
[Default = all]</td>
<td align="center" valign="middle">no</td>
</tr>
<tr>
<td valign="top">excludetarget</td>
<td align="center" valign="middle">no</td>
</tr>
<tr>
<td valign="top">includetask</td>
<td valign="top" rowspan=2>A comma-separated list of task to automaticly
record or not. This could be difficult as it could conflict with the
<code>includetarget/excludetarget</code>. (e.g.:
<code>includetarget="compile" exlcudetask="javac"</code>, what should
happen?)</td>
<td align="center" valign="middle">no</td>
</tr>
<tr>
<td valign="top">excludetask</td>
<td align="center" valign="middle">no</td>
</tr>
<tr>
<td valign="top">action</td>
<td valign="top">add greater flexability to the action attribute. Things
like <code>close</code> to close the print stream.</td>
<td align="center" valign="top">no</td>
</tr>
<tr>
<td valign="top"></td>
<td valign="top"></td>
<td align="center" valign="top"></td>
</tr>
</table>
