Re: filter: Windows backslashes in a properties file

[peter reilly <pe...@corvil.com>]

Ah the wonders of dos^h^h^hnt^h^hwindows^h^h^h^h^h^h^hxp
In dos both / and \ are allowed for file separators. Most but
not all programs understand / as a file separator.

\ is used as an excape character for property files (and
for most normal usages).

If possible, I would use / in the properties file, in which case
one can use the <path> and <pathconvert> to convert \ to /.

<path id="basedir" path="${basedir}"/>
<pathconvert targetos="unix" refid="basedir" 
                   property="converted.basedir"/>
<echo message="converted ${converted.basedir}"/>

<copy file="${src.test.dir}/templates/LorTest.properties"
          todir="${build.test.dir}">
    <filterset>
        <filter token="LOR_HOME" value="${converted.basedir}"/>
      </filterset>
</copy>

Peter.
