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 ;)

Yeah, that's what I did. The small repro just shows that it doesn't affect the
string with the \'s whatsoever... If there were actual instances of \\ in
there maybe it would do something, but there are only \'s. Seems like for the
saving down of the property, it uses escape characters, but for the
substitution part, it doesn't. I'd call it a bug I think.

OK, so in looking more closely, what I meant to say was to do the <propertyregex
property="tmpProp" first and then the one you had initially afterward using the
first :)
If I get a free moment today I'll see if I can get it to work... Little busy
at the moment - maybe at lunch today :)

I tried this Scot, but it didn't do it. So here's an easy repro:
<project default="main">
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<property name="myProp" 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}"/>

It produces:
[echo] tmpProp is: C:\myDog\Loves\Big\Juicy\Bones
If I change it to:

it crashes with:

I don't know that what we're trying to do is possible with propertyregex. It
seems it may need some scripting. All I'm really trying to do is:
if(property1.indexOf(string1) >= 0) then return true;
I'll take a look at how to achieve this tomorrow. Thanks!

Mmm - you may need to do this before your first propertyregex
<propertyregex property="tmpProp" input="${propertyList}" override="true" regexp="\\"
replace="\\\\" globale="true"/>
Basically the above will escape the \

Well, out of that error and on to the next. It seems that PropertyRegEx has an issue

Hi all. I wrote a MacroDef to append a string to a property. All works as planned until
you slip a "\" in there and then it gets jacked up. My javascripting has MUCH
