Matt Benson commented on IO-172:
--------------------------------
Any problem with including this implementation in [io], though?
> Support directory scanning based on Ant-like include/exclude patterns
> ---------------------------------------------------------------------
>
> Key: IO-172
> URL: https://issues.apache.org/jira/browse/IO-172
> Project: Commons IO
> Issue Type: New Feature
> Components: Utilities
> Affects Versions: 1.4
> Reporter: Benjamin Bentmann
>
> While IO offers a rich set of {{IOFileFilters}} for finding files in
> directories, I feel it's missing a concept similar to Ant's file sets. For
> example, how would one search for files that match "**/*.xml" but that don't
> match "bad/**"? The sketched example would require to exclude the directory
> "bad" but only if it is the first component of the path, something like
> "foo/bad/bar.xml" still needs to be included.
> Given the increased flexibility of [Ant-like
> patterns|http://ant.apache.org/manual/dirtasks.html#patterns], it would be
> cool to have something similar to Ant's
> [{{DirectoryScanner}}|http://svn.apache.org/viewvc/ant/core/trunk/src/main/org/apache/tools/ant/DirectoryScanner.java?view=markup]
> available in Commons IO.
> Personally, I wouldn't need a full copy of the mentioned class, I believe
> some method like
> {code:java}
> Collection<String> scanDirectory(File dir, Collection<String> includes,
> Collection<String> excludes)
> {code}
> in {{FileUtils}} would just suffice. Some default excludes like SCM metadata
> files could be provided as a public static final and unmodifiable string
> collection. The return value should include path names relative to the base
> directory instead of absolute paths (it's easy for the caller to resolve the
> files against the base directory but it's error-prone to relativize absolute
> paths).
