http://issues.apache.org/bugzilla/show_bug.cgi?id=31375 regexp type mapper doesn't work without the '^' character. [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |INVALID ------- Additional Comments From [EMAIL PROTECTED] 2004-09-23 15:39 ------- Ok. this is a bit embarrassing...what I discovered is that, after much trial and error, the use of a mapper element within a propertyset is quite adversely affected by the lack of a preceding <propertyref> element of appropriate constraint. So, when I finally stopped 'trying things' to make the propertyset work (within an echoproperties element later), my conclusion was clouded by having 'tried' the inclusion of a ^ in the mapper's regex expression combined (most likely overlooked) with the inclusion of the preceding propertyref element. Here's the shorter, simpler test case: <?xml version="1.0" encoding="UTF-8"?> <project default="dist" name="test" basedir="."> <property name="filter.local.foo" value="1234"/> <property name="filter.dev.foo" value="4321"/> <property name="filter.generic.foo" value="bar"/> <property name="filterset" value="local"/> <target name="dist"> <propertyset id="specific.filters"> <propertyref regex="filter\.${filterset}\..*"/> <mapper type="regexp" from="filter\.${filterset}\.(.*)" to="filter.\1"/> </propertyset> <echoproperties> <propertyset refid="specific.filters"/> </echoproperties> </target> </project> This produces: [echoproperties] filter.foo=1234 And, removing the <propertyref ...> from the propertyset (preceding the mapper sub-element) produces no output: Long story - short: I made a faulty assessment about the mapper functionality based on working too many hours and being too tired to sort out my experimental data. The conclusion is that THIS IS NOT A BUG. That said, I would recommend that, in the documentation on propertyset in the section on using a mapper element, it be explicitly stated what the relationship and interaction is between the mapper element and the preceding propertyref element. Most importantly, that a mapper element won't work without that propertyref element. This is not clear. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
