Summary: <replaceregex> in <tokenfilter> does not honour
flags="s"
Product: Ant
Version: 1.6.5
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Core tasks
AssignedTo: dev@ant.apache.org
ReportedBy: matt@cenqua.com
When using <repalceregex>, specifying flags="s" has no effect (that is, you want the regex to span
lines).
Example:
<project basedir="." default="test" name="test">
<target name="test">
<copy overwrite="true" file="src.txt" tofile="dest.txt">
<filterchain>
<tokenfilter>
<replaceregex pattern="START.*" replace="SNIP" flags="gs"/>
</tokenfilter>
</filterchain>
</copy>
</target>
</project>
== src.txt ==
line1
foo START this bit should disappear
and so should this bit
== ==
To Reproduce:
Run the above build.xml, and look at dest.txt. Everything from START to EOF should be replaced with
"snip", but it is not. Changing or removing the byline attribute has no effect.
Diagnosis:
I had a look at TokenFilter.ChainableReaderFilter. The "byline" attribute seems to be what I want, but
running this through a debugger proved that ChainableReaderFilter.chain(Reader) is *never* called.
Solution:
Not to sure, reading the whole TokenFilter/ChainableReader thing was like chasing a rabbit down a hole
:P
Workaround:
I wrote my own FilteredReader to use with <filterreader>
