Hello,
I have a stylistic question to the copy task and the mappers.
I have the following situation: I have four directories, one
reference/source directory, one reference/compiled directory, one
current/source directory and a current/compiled directory:
+- reference
| +- source
| +- compiled
|
+- current
+- source
+- compiled
The task is to copy all the files from the reference/compiled directory to
the current/compiled directory, for which the source files does not differ.
e.g:
reference/source
* equal.ref
* diff.ref
* only_ref.ref
reference/compiled
* same as above with .bin suffix
current/source
* equal.ref (equal to reference/source)
* diff.ref (different content)
current/compiled
<<empty>>
In the situation above the task should only copy
'reference/compiled/equal.bin' to the 'current/compiled' directory.
Currently I implemented this with a <for> loop over a fileset, which
includes the equal files of the both source directories. In the loop, I
change the filename/path of the reference/source folder to the reference
compiled folder.
This works, but does not look very nice.
Is there an easier solutions (The compilation has nothing to do with
Java/C++, so that dedicated tasks for this cannot be used).
And finally here the code snippet, how it is currently implemented:
<property name="current.source" value="current\source" />
<property name="current.compiled" value="current\compiled" />
<property name="reference.source" value="reference\source" />
<property name="reference.compiled" value="reference\compiled" />
<!-- replace backslashes with slashes, so that the path can be used in
regular expressions -->
<propertyregex property="normalized.current.source" override="true"
input="${current.source}" regexp="\\" replace="/" />
<propertyregex property="normalized.reference.compiled" override="true"
input="${reference.compiled}" regexp="\\" replace="/" />
<!-- Iterate over the files, which are equal in both source directories -->
<for param="filename" >
<fileset dir="${current.source}" includes="**/*.ref" >
<not>
<different targetdir="${reference.source}"
ignoreFileTimes="true"
ignoreContents="false" />
</not>
</fileset>
<sequential>
<propertyregex property="normalized.filename" override="true"
input="@{filename}" regexp="\\" replace="/" />
<!-- replace the path to the source with the path to the compiled
reference -->
<propertyregex property="normalized.filename" override="true"
input="${normalized.filename}"
regexp="(.*)${normalized.current.source}/([^/]*)\.([^/\.]*)"
select="\1${normalized.reference.compiled}/\2.bin" />
<copy file="${normalized.filename}" todir="${current.compiled}" />
</sequential>
</for>
