Re: os.name for windows return "Windows XP"?

Peter Reilly Mon, 26 Jan 2004 11:07:22 -0800

In a previous project we simply used:
  <property file="${os.name}.properties"/>

The space in the name is not a problem.
The os's used were: "Windows 2000", "Windows XP",
"Windows NT", "Linux", "HP-UX" and "SunOS".
The windows properties were mostly copies of each other,
but there were on or two differences.

If you just want a property file for windows like oses and one
for the rest you could do.
<condition property="iswindows">
   <os family="windows"/>
</condition>

<target name="init" depends = "windows.init, other.init"/>
<target name="windows.init" if="iswindows">
  <property file="windows.properties"/>
</target>
<target name="others.init" unless="iswindows">
  <property file="notwindows.properties"/>
</target>

or:
<condition property="properties.filename" value="windows.properties">
   <os family="windows"/>
</condition>
<property name="properties.filename" value="notwindows.properties">

<property file="${properties.filename}"/>

Using ant-contribs <if/> would make a target/property free
control structure:
<if>
  <os family="windows"/>
   <then>
     <property file="windows.properties"/>
   </then>
   <else>
      <property file="notwindows.properties"/>
   </else>
</if>

All,

How can I improve the following code in ant?

Thanks

Hi,
There must be someone who is dealing with the same issue. I am trying to
take multiplatform builds with different ${os.name}.properties file. Linux
is not a problem, Linux.properties. What about Windows? It becomes Windows
XP.properties files.
Can someone enlight me the better way to do this with one word .properties
name?
I've used this approach in the past
 <target name="set-conditions">
   <condition property="linux">
     <os name="linux"/>
   </condition>
   <condition property="solaris">
     <os name="SunOS"/>
   </condition>
   <condition property="windows">
     <os family="windows"/>
   </condition>
 </target>
You could probably use a single property name and different value attributes and load the properties that way. Depends if you want to use if attributes later on.
