Subject Re: Zero-Padding an Int Ant Property
Date Fri, 25 Aug 2006 00:00:08 GMT
Hello Ryan,

under "Optional Tasks" in the manual there is something called <propertyfile/>.

it can format numbers, so this might be what you want.

since its output is a file, you will need to load the generated property file after having
used <propertyfile/>

so 

<propertyfile file="some.generated.properties">
  <entry  key="formated.int" type="int" value="${buildNum}" operation="=" pattern="0000"/>
</propertyfile>
<property file="some.generated.properties"/>
<delete file="some.generated.properties"/>

should do the job.

Regards,

Antoine

Betreff: Zero-Padding an Int Ant Property

> Hello all,
