Subject native2ascii task
Date Wed, 20 Sep 2000 03:15:17 GMT

I've written the attached native2ascii task, which I'd like to submit
for inclusion with ant.  It essentially serves as a wrapper for the
jdk native2ascii, with some additional smarts to act as a MatchingTask
and do dependency checking.  A draft usage is below.  Thanks to
Hiroaki Nakamura <>, for useful comments on
how the task ought work (and prodding me to make it a bit more useful
than I'd originally planed).



Converts files from native encodings to ascii with escaped Unicode.
A common usage is to convert source files maintained in a native
operating system encoding, to ascii prior to compilation.

All matching files in the source directory are converted from a
native encoding to ascii.  If no encoding is specified, the default
encoding for the JVM is used.  If ext is specified, then output
files are renamed to use it as a new extension.  If dest and
src point to the same directory, ext is required.

This is a directory based task, and supports includes, includesfile,
excludes, excludesfile, and defaultexcludes along with its specific

<native2ascii encoding="EUCJIS" src="srcdir" dest="srcdir"
   includes="**/*.eucjis" ext=".java" />

Converts all files in the directory srcdir ending in eucjis
from the EUCJIS encoding to ascii and renames the to end in

<native2ascii encoding='EUCJIS" src="native/japanese" dest="src"
   includes="**/*.java />

Converts all the files ending in .java in the directory native/japanese
to ascii, placing the results in the directory src.  The names of
the files remain the same.
