Subject Re: AppendToProperty MacroDef
Date Thu, 21 Jan 2010 15:53:27 GMT
Wondering over toward <scriptdef> which I haven't used before.  I saw <element>
in there and can't see it described anywhere in the doc.  Can someone give me a reference?

Thanks,
Eric

And to leverage your \n example:

<project default="main">
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<property name="myProp" value="C:\noDog\Hates\Big\Juicy\Bones"/>
<property name="myProp2" value="C:\\noDog\\Hates\\Big\\Juicy\\Bones"/>
<property name="myProp3" value="C:\noDog\\Hates\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="tmpProp is:  ${tmpProp2}"/>
    <propertyregex property="tmpProp3" input="${myProp3}" override="true" regexp="\\"
replace="\\\\" global="true"/>
    <echo message="tmpProp is:  ${tmpProp3}"/>
    <propertyregex property="tmpProp4" input="${myProp}" override="true" regexp="\"
replace="\\" global="true"/>
    <echo message="tmpProp is:  ${tmpProp4}"/>
  </target>
</project>

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

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.
