http://nagoya.apache.org/bugzilla/show_bug.cgi?id=23106 Regexp Mapper: Empty selection groups return string "null" ------- Additional Comments From [EMAIL PROTECTED] 2003-09-11 15:27 ------- Ooops... how did I do *that*?!? Assume a directory with two files with numeric names: 1-06 7 We want to rename these files to "After-1-6" and "After-7". The ant script below will result in the files being renamed to After-1-6 After-7nullnull ---- <project name="Package" default="all" basedir="."> <description> ANT Build file to create zip file for release, move it to the releases directory, and notify everyone it is ready. </description> <target name="all"> <copy todir="${basedir}" > <fileset dir="${basedir}"> <include name="*"/> <size value="0"/> </fileset> <mapper type="regexp" from="([1-9])(-)?(?:0)?([0-9]{1,2})?" to="After-\1\2\3" /> </copy> </target> </project> ---- End of a run with ant -debug all: fileset: Setup scanner in dir S:\shared\2003-TEST with patternSet{ includes: [*] excludes: [] } [copy] 1-06 added as After-1-6 doesn't exist. [copy] 7 added as After-7nullnull doesn't exist. [copy] Copying 2 files to S:\shared\2003-TEST [copy] Copying S:\shared\2003-TEST\1-06 to S:\shared\2003-TEST\After-1-6 [copy] Copying S:\shared\2003-TEST\7 to S:\shared\2003-TEST\After-7nullnull BUILD SUCCESSFUL I believe that the regexp mapper should append empty strings in place of "null" to the result of the mapping. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
