Let me give you a better example Scot. Substitution seems to ignore escape
characters entirely. As the task is written now, I don't imagine there is a
way to replace \'s.
<project default="main">
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<property name="myProp" value="C:\myDog\Loves\Big\Juicy\Bones"/>
<property name="myProp2" value="C:\\myDog\\Loves\\Big\\Juicy\\Bones"/>
<property name="myProp3" value="C:\myDog\\Loves\Big\\Juicy\Bones"/>
<target name="main">
<propertyregex property="tmpProp" input="${myProp}" override="true"
regexp="\\" replace="\\\\" global="true"/>
<echo message="tmpProp is: ${tmpProp}"/>
<propertyregex property="tmpProp2" input="${myProp2}" override="true"
regexp="\\" replace="\\\\" global="true"/>
<echo message="tmpProp2 is: ${tmpProp2}"/>
<propertyregex property="tmpProp3" input="${myProp3}" override="true"
regexp="\\" replace="\\\\" global="true"/>
<echo message="tmpProp3 is: ${tmpProp3}"/>
<propertyregex property="tmpProp4" input="${myProp}" override="true"
regexp="\" replace="\\" global="true"/>
<echo message="tmpProp4 is: ${tmpProp4}"/>
</target>
</project>
Produces:
main:
[echo] tmpProp is: C:\myDog\Loves\Big\Juicy\Bones
[echo] tmpProp2 is: C:\\myDog\\Loves\\Big\\Juicy\\Bones
[echo] tmpProp3 is: C:\myDog\\Loves\Big\\Juicy\Bones

Subject: Re: AppendToProperty MacroDef
I might be wrong but I think the output you are seeing is correct - as in
the \ is escapeed thereby printing only 1 \ not 2... For example if you
consider \n it is emitted as a newline...but if you do \\n the output will
be a literal \n (as in a backslash followed by the letter n)... Try
printing out the property when you don't do the regex for \\\\ - for
example something like:
C:\foo\nbar
I bet the output has a new line in it ;)
