<div class="block">Converts text to local OS formatting conventions, as well as repair text
damaged by misconfigured or misguided editors or file transfer programs.
<p>
This filter can take the following arguments:
<ul>
<li>eof
<li>eol
<li>fixlast
<li>javafiles
<li>tab
<li>tablength
</ul>
None of which are required.
<p>
This version generalises the handling of EOL characters, and allows for
CR-only line endings (the standard on Mac systems prior to OS X). Tab
handling has also been generalised to accommodate any tabwidth from 2 to 80,
inclusive. Importantly, it can leave untouched any literal TAB characters
embedded within Java string or character constants.
<p>
<em>Caution:</em> run with care on carefully formatted files. This may
sound obvious, but if you don't specify asis, presume that your files are
going to be modified. If "tabs" is "add" or "remove", whitespace characters
may be added or removed as necessary. Similarly, for EOLs, eol="asis"
actually means convert to your native O/S EOL convention while eol="crlf" or
cr="add" can result in CR characters being removed in one special case
accommodated, i.e., CRCRLF is regarded as a single EOL to handle cases where
other programs have converted CRLF into CRCRLF.
<P>
Example:
<pre>
<<fixcrlf tab="add" eol="crlf" eof="asis"/>
</pre>
Or:
<pre>
<filterreader classname="org.apache.tools.ant.filters.FixCrLfFilter">
<param eol="crlf" tab="asis"/>
