I'm sure that this is trivial - but have been bashing my head against a wall
I'm trying to take a directory full of mustache templates (html files essentially) and combine them into one file - wrapping each one with a tag
Example:
File1 = <a>This is a Link</a>
File2 = <b>This is in bold</b>
I want the output to look like:
<script type="text/mustache" id="File1">
<a>This is a Link</a>
</script>
<script type="text/mustache" id="File2">
<b>This is in bold</b>
</script>
I'm using a concat task
<concat destfile="mustache.js" fixlastline="yes">
<fileset dir="." includes="**/*.mustache"/>
</concat>
but can't figure out how to get the script blocks to display
At first i thought about using concat somehow with header and footer but didn't find a working solution.
If you not shy away from using some Ant addon, here's a solution based on Flaka =
<project name="demo" xmlns:fl="antlib:it.haefelinger.flaka">
<!-- make standard ant tasks understand EL expressions -->
<fl:install-property-handler />
<!-- we use path instead of pure fileset because we need
absolute filenames for loadfile later in for loop -->
<path id="foo">
<fileset dir="/some/path" includes="**/*.mustache"/>
</path>
<!-- iterate over the path/fileset -->
<fl:for var="file" in="split('${toString:foo}', ':')">
<!-- unset property for next loop -->
<fl:unset>content</fl:unset>
<!-- load file contents to property -->
<loadfile property="content" srcFile="#{file}"/>
<echo file="/some/path/foobar/mustache.js" append="true">
<!-- the id attribute gets filled with the basename of the current fileitem -->
<![CDATA[<script type="text/mustache" id="#{replace(file, '$1' , '.+?(\w+)\..+' )}">
#{trim('${content}')}
</script>]]></echo>
</fl:for>
</project>
Note : 1. my leftmost notation within the echo task to avoid unnecessary blanks in the resulting file ! just write as in my example above and your file will look like your wanted output
2. the <![CDATA[...]]> is needed, otherwise you'll get some error like "echo doesn't support the nested "script" element."

I'm trying to concatenate an unknown number of HTML files into one XML file.
That's no problem with:
<concat destfile="${temp.dir}/file.xml" encoding="UTF-8" outputencoding="UTF-8">
<fileset dir="${html.dir}" includes="**/*.html" />
</concat>
Now what I would like to do is, for each file of the fileset, insert its path into the concatenated file.
Example
I have the following HTML files in C:\whatever\sources:
A.html
B.html
In the result XML file, I'd like to get:
<allfiles>
<html url="C:\whatever\sources\A.html>...content of A.html...</html>
<html url="C:\whatever\sources\B.html>...content of B.html...</html>
</allfiles>
Is there a way to do that simply without reinventing the wheel and if possible without using ant-contrib?
As mentioned, you can use a scriptfilter inside filterchain task to run Javascript inside your Ant build.
For example:
<concat destfile="${temp.dir}/file.xml" encoding="UTF-8" outputencoding="UTF-8">
<fileset dir="${html.dir}" includes="**/*.html" id="my-files"/>
<filterchain>
<tokenfilter>
<filetokenizer />
<scriptfilter language="javascript" byline="false"><![CDATA[
content = self.getToken();
// Modify content of token.
//content=content.replaceAll("(?s)/\\*.*?\\*/","");
self.setToken(content);
]]></scriptfilter>
</tokenfilter>
<striplinecomments>
<comment value="//"/>
</striplinecomments>
<striplinebreaks/>
</filterchain>
</concat>

Is it possible for an xml task to copy the value of one node into another node for each element in a list?
Source XML:
<a>
<b>
<c1>foo</c1>
<c2></c2>
</b>
<b>
<c1>bar</c1>
<c2></c2>
</b>
...
</a>
Destination XML:
<a>
<b>
<c1>foo</c1>
<c2>foo</c2>
</b>
<b>
<c1>bar</c1>
<c2>bar</c2>
</b>
...
</a>
I'm trying to accomplish the above in my ant task, but I con't seem to find a way to do it, here is what I am doing so far,
<target name="mergefile">
<!-- Read the source into a buffer -->
<xmltask source="source.xml" clearBuffers="list">
<copy path="/a" buffer="list" append="true"/>
</xmltask>
<!-- Write them to the output -->
<xmltask source="destination.xml" dest="destination.xml"
outputter="simple">
<!-- First clear all the old paths. -->
<remove path="/a/b"/>
<!-- Then add the resolved ones. -->
<paste path="/a" buffer="list"></paste>
<!-- Copy the value over? -->
<replace path="a/b/c2/text()" withText="No Idea"/>
</xmltask>
</target>
Any idea of how to copy the value from one node to the next for all the elements in the list?
As, I guess, is usually the case, writing my own task was the only way I could see to do it.
#Override
public void execute() throws BuildException {
//Read file line by line, regex test on each line,
//matches get written back twice.
}
Then calling it was,
<copyregmatch file="myfile.xml" regex=".*replace.*" />
I have for example the js file containing these lines:
<script defer src="/js/libs/ui.achtung.js"></script>
<script defer src="/js/libs/jquery.tipsy.js"></script>
<script defer src="/js/libs/jquery.mousewheel.js"></script>
I need to concatenate these files at one and place a link to newly created file here replacing existing scripts.
So the algorithm is a) read lines with scripts b) concatenate all scripts to one c) replace script links to only one
I cant find a decision to read multiple lines to place each of them to separate property or so.
Can anyone help me?
To read multiple lines, have a look at:
Ant: get multiple matches with propertyregex
The example there extract
ABC
ABCD
ABCE
out of
test.ABC.test
test.ABCD.test
test.ABCE.test
with
<target name="test">
<loadfile property="record" srcFile="./index.html">
<filterchain>
<tokenfilter>
<containsregex pattern=".*test\.([^\.]*)\.test.*" replace="\1"/>
</tokenfilter>
</filterchain>
</loadfile>
<echo message="${record}" />
</target>
I'm trying to debug a macrodef in Ant. I cannot seem to find a way to display the contents of a parameter sent as an element.
<project name='debug.macrodef'>
<macrodef name='def.to.debug'>
<attribute name='attr' />
<element name='elem' />
<sequential>
<echo>Sure, the attribute is easy to debug: #{attr}</echo>
<echo>The element works only in restricted cases: <elem /> </echo>
<!-- This works only if <elem /> doesn't contain anything but a
textnode, if there were any elements in there echo would
complain it doesn't understand them. -->
</sequential>
</macrodef>
<target name='works'>
<def.to.debug attr='contents of attribute'>
<elem>contents of elem</elem>
</def.to.debug>
</target>
<target name='does.not.work'>
<def.to.debug attr='contents of attribute'>
<elem><sub.elem>contents of sub.elem</sub.elem></elem>
</def.to.debug>
</target>
</project>
Example run:
$ ant works
...
works:
[echo] Sure, the attribute is easy to debug: contents of attribute
[echo] The element works only in restricted cases: contents of elem
...
$ ant does.not.work
...
does.not.work:
[echo] Sure, the attribute is easy to debug: contents of attribute
BUILD FAILED
.../build.xml:21: The following error occurred while executing this line:
.../build.xml:7: echo doesn't support the nested "sub.elem" element.
...
So I guess I need either a way to get the contents of the <elem /> into a property somehow (some extended macrodef implementation might have that), or I need a sort of <element-echo><elem /></element-echo> that could print out whatever XML tree you put inside. Does anyone know of an implementation of either of these? Any third, unanticipated way of getting the data out is of course also welcome.
How about the echoxml task?
In your example build file replacing the line
<echo>The element works only in restricted cases: <elem /> </echo>
with
<echoxml><elem /></echoxml>
results in
$ ant does.not.work
...
does.not.work:
[echo] Sure, the attribute is easy to debug: contents of attribute
<?xml version="1.0" encoding="UTF-8"?>
<sub.elem>contents of sub.elem</sub.elem>
Perhaps the XML declaration is not wanted though. You might use the echoxml file attribute to put the output to a temporary file, then read that file and remove the declaration, or reformat the information as you see fit.
edit
On reflection, you can probably get close to what you describe, for example this sequential body of your macrodef
<sequential>
<echo>Sure, the attribute is easy to debug: #{attr}</echo>
<echoxml file="macro_elem.xml"><elem /></echoxml>
<loadfile property="elem" srcFile="macro_elem.xml">
<filterchain>
<LineContainsRegexp negate="yes">
<regexp pattern=".xml version=.1.0. encoding=.UTF-8..." />
</LineContainsRegexp>
</filterchain>
</loadfile>
<echo message="${elem}" />
</sequential>
gives
$ ant does.not.work
...
does.not.work:
[echo] Sure, the attribute is easy to debug: contents of attribute
[echo] <sub.elem>contents of sub.elem</sub.elem>
How can I get the value of the current target ant?
Does it exist a special variable something called TARGET?
Based on the issue you have to patch ant or used javascript:
<target name="test">
<script language="javascript">
project.setNewProperty("current_target", self.getOwningTarget());
</script>
<echo>${current_target}</echo>
</target>
In ant 1.8.2 you can use ${ant.project.invoked-targets}
However, looking at the commit logs
http://svn.apache.org/viewvc?view=revision&revision=663061
I'm guessing its been available since 1.7.1
My answer, using antcontrib
<macrodef name="showtargetname">
<attribute name="property"/>
<sequential>
<!-- make temporary variable -->
<propertycopy name="__tempvar__" from="#{property}"/>
<!-- Using Javascript functions to convert the string -->
<script language="javascript"> <![CDATA[
currValue = [project-name].getThreadTask(java.lang.Thread.currentThread()).getTask().getOwningTarget().getName();
[project-name].setProperty("__tempvar__", currValue);
]]>
</script>
<!-- copy result -->
<var name="#{property}" value="${__tempvar__}"/>
<!-- remove temp var -->
<var name="__tempvar__" unset="true"/>
</sequential>
</macrodef>
Usage:
<showtargetname property="mycurrenttarget"/>
I think you can't, unless you spend some time coding your own custom tasks (http://ant.apache.org/manual/tutorial-writing-tasks.html)
The built-in properties you can display are: basedir, ant.file, ant.version, ant.project.name, ant.java.version
If you run ant using the -projecthelp arg:
ant -projecthelp
you will get a listing of the main targets specified in the build.xml (or other build file as declared on the commandline).
