I want to read a text file which has text as follows(sample)
abc ip-32-56-198-18.com xyz
now the text 32-56-198-18 updates dynamically and now i want to take this text and create ip address for further use.
I have done this using PHP but with ant i am in problem as I cant get the position of specific sub-string like php in ant.
I have seen this question its similar but he knows the position of the sub-string my position is too not fix as abc can be string of any length. Only ip- and .com are fix which are sufficient to find the required.
If you all say that its not possible using ant then i can focus or do something else or try different method to fix my problem dropping the plan of reading the same from ANT.
Thanks to all.
Update: abc ip-23-56-89-45.com-asdhba.sip-65-59-85-12.com xyz
for the above example the code should work and it should give me 23-56-89-45
Thanks.
As said in the most rated answer to the question you mentioned, you could try using PropertyRegex from Ant-conrtib.
<project>
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
<classpath>
<pathelement location="./ant-contrib-1.0b3.jar"/>
</classpath>
</taskdef>
<!-- You can load the value from file -->
<property name="input" value="abc ip-32-56-198-18.com xyz"/>
<propertyregex property="ip"
input="${input}"
regexp=".*?ip-(.*?)\.com.*"
select="\1"
defaultValue="${path}" />
<echo message="IP addr: ${ip}"/>
</project>

Can the token itself be parsed from other values from within the property file?
Is it possible to evaluate the token key, without hardcoding the token? Can the token itself be parsed from other values from within the property file?
For example, if the properties file has the following tokens (test.properties):
module_no = 01
module_code = bb
title_01_aa = ABC
title_02_aa = DEF
title_03_aa = GHI
title_01_bb = JKL
title_02_bb = MNO
title_03_bb = PQR
Contents of build.xml
<?xml version="1.0" encoding="utf-8"?>
<project default="repl">
<property file="test.properties" />
<target name="repl">
<replace file="test.txt" token="module_title" value="title_${module_no}_${module_code}" />
</target>
</project>
Sample content with text:
Welcome to module_title.
The replace task will result in:
Welcome to title_01_bb.
How to achieve this instead?
Welcome to JKL.
This might be very basic, but please do guide me in the right direction. Thank you.
Nested property expansion does not work by default in Ant as described in the documentation:
Nesting of Braces
In its default configuration Ant will not try to balance braces in property expansions, it will only consume the text up to the first closing brace when creating a property name. I.e. when expanding something like ${a${b}} it will be translated into two parts:
the expansion of property a${b - likely nothing useful.
the literal text } resulting from the second closing brace
This means you can't use easily expand properties whose names are given by properties, but there are some workarounds for older versions of Ant. With Ant 1.8.0 and the the props Antlib you can configure Ant to use the NestedPropertyExpander defined there if you need such a feature.
If you check the workarounds link, one solution is to use a macrodef to copy the property:
<property file="test.properties" />
<target name="repl">
<gettitleprop name="titleprop" moduleno="${module_no}" modulecode="${module_code}" />
<replace file="test.txt" token="module_title" value="${titleprop}" />
</target>
<macrodef name="gettitleprop">
<attribute name="name"/>
<attribute name="moduleno"/>
<attribute name="modulecode"/>
<sequential>
<property name="#{name}" value="${title_#{moduleno}_#{modulecode}}"/>
</sequential>
</macrodef>
I have jar file having some properties files in it like log4j.properties and config.properties. Following is my ant script for yguard. Everything else is working but the properties file updation.
<target name="yguard">
<taskdef name="yguard" classname="com.yworks.yguard.YGuardTask" classpath="lib/yguard.jar" />
<yguard>
<inoutpairs resources="none">
<fileset dir="${basedir}">
<include name="MyApp.jar" />
</fileset>
<mapper type="glob" from="MyApp.jar" to="MyAppObs.jar" />
</inoutpairs>
<externalclasses>
<pathelement location="lib/log4j-1.2.17.jar" />
</externalclasses>
<rename conservemanifest="true" mainclass="com.amit.Application" >
<adjust replaceContent="true" >
<include name="**/*.properties" />
</adjust>
</rename>
</yguard>
</target>
config.properties file
com.amit.Application.param1 = something
I found some question in stackoverflow but they didn't help. One place it was mentioned that the file (like jsp, xml, properties) should be in the jar file which I already have. But my yguard obfuscated file just get the files copied as it is.
I tried many combinations with rename & adjust tags but nothing worked for me.
Following post I already visited
Is it possible to manage logs through Obfuscation with yGuard?
How to include obfuscated jar file into a war file
Apparently you want yGuard to obfuscate the name of the field param1, because com.amit.Application is obviously your entry point and yGuard excludes the given main class automatically. So basically you want the outcome to be something like
com.amit.Application.AÖÜF = something
This isn't possible, because yGuard can only adjust class names in property files, as state here: yGuard Manual
Hi all please give a look to this code
in my properties file i have
win-x86.pc-shared-location=E:\Ant_Scripts
Now below i am trying to call PrintInstallerName_build from my build.xml,while as PrintInstallerName_build is in test.xml. In build.xml file,${platform.id} has value=win-x86 in the calling target and in called target param1 also has value=win-x86
<target name="PrintInstallerName" >
<echo>PlatForm.Id====>${platform.id}</echo>
<ant antfile="test.xml" target="PrintInstallerName_build">
<property name="param1" value="${platform.id}"/>
</ant>
<target name="PrintInstallerName_build" >
<echo>${param1.pc-shared-location}</echo><!--${param1.pc-shared-location}-->
<echo>${param1}.pc-shared-location}</echo><!--win-x86.pc-shared-location-->
<echo>${win-x86.pc-shared-location}</echo><!--E:\\Ant_Scripts-->
</target>
as you can see only the last statement gives correct output but it is hardcoded,i want to use param1 and the output should be E:\\Ant_Scripts i tried to use $ and # but none works,may be i am doing wrong somewhere can someone help please,i am struck and tomorrow is its DOD.

You can use <propertycopy> to make it happen.
Consider that you need to have the property value of ${propA${propB}}
Use ant tag of propertycopy as follows:
<propertycopy property="myproperty" from="PropA.${PropB}"/>
<echo >${myproperty}</echo>
This will echo the value of ${propA${propB}}
<target name="PrintInstallerName_process" >
<echo>${param1}</echo><!--win-x86-->
<macrodef name="testing">
<attribute name="v" default="NOT SET"/>
<element name="some-tasks" optional="yes"/>
<sequential>
<echo>Source Dir of ${param1}: ${#{v}}</echo><!-- Dir of Win-x86:E:\Ant_Scripts-->
<some-tasks/>
</sequential>
</macrodef>
<testing v="${param1}.pc-shared-location">
<some-tasks>
</some-tasks>
</testing>

this is the way it works and for me it works fine anyways #sudocode your tip took me there so thank you very much
I want to write a code in such a way that I will remove platform from first 3 lines and then take only the platform name and I will suffix that with installer-zip.${platform_name}.
platform.win-x86=true
platform.win-x64=true
platform.unix=false
installer-zip.win-x86=E:\abc.jar
installer-zip.win-x64=E:\def.jar
Now if the selected item is win-x86 then printing installer-zip.${platform_name} should give me E:\abc.jar. I tried ${installer-zip.${platform_name}} and many other things but they are not working
You cannot do this with regular ant, but you can do this with ant-contrib.
In particular, there is a contrib task property-regex.
So something like:
<propertyregex property="$newProperty"
input="$oldProperty"
regexp="^platform\.(,*)$"
select="\1"
casesensitive="false" />
EDIT: and then...
<property name=desiredProperty value="installer-zip.${newProperty}" />
That should give you enough to work out the exact solution you're looking for...
Using Apache Ant 1.7.1
It looks like the Ant Filter task can't resolve the same property several times in one line when recurse is set to true. I can't find any mention of this in the Ant docs. Is this supposed to happen?
Using this ant build file:
<project basedir="." default="assemble" >
<macrodef name="copy-and-filter">
<sequential>
<copy tofile="to.txt" file="from.txt" overwrite="true">
<filterset recurse="true">
<filtersfile file="filters.properties"/>
</filterset>
</copy>
</sequential>
</macrodef>
<target name="assemble">
<copy-and-filter />
</target>
</project>
with these files:
from.txt:
I want my broker to be: #broker.url#
and my client to be: #client.url#
filters.properties:
myval=fish
broker.url=-#myval#-
client.url=#myval#-#myval#
I get the output to be:
i want my broker to be: -fish-
and my client to be: myval
and not what I expected which would be this:
i want my broker to be: -fish-
and my client to be: fish-fish
If I set recurse to false then I get the 'correct' behaviour.
i want my broker to be: -#myval#-
and my client to be: #myval#-#myval#
Why is this?
The recurse flag is intended to look for more tokens after an initial replace occurs, but it won't work if the same token is used again. The problem is that setting recurse=true causes an infinite loop. See the output from Ant:
Infinite loop in tokens. Currently known token tokens: [client.url, myval]
Problem token: #myval# called from #myval#
I don't think its possible to do what you want to be able to do using the filterset task. What are you using the to.txt file for? Is it to provide a system configuration file?
