> Project: Commons IO
> Issue Type: Improvement
> Reporter: Mark
> Priority: Minor
>
> Can we please introduce a simpler file search method than the existing ones
> that are using filters?
> Currently I'm using the ant lib's DirectoryScanner for that purpose. However,
> ant comes with quite a few dependencies, introducing unnecessary overhead and
> bloat.
> Examples:
> {code:java}
> // select all sub directories (final slash) of cwd
> File[] f = FileUtils.glob("**/");
> // select first sub dir, null if there is none
> File f = FileUtils.globFirst("**/");
> // exception if there is none
> File f = FileUtils.globFirstE("**/");
> // select exactly one sub dir, return null if there are more or less
> File f = FileUtils.globOne("**/");
> // select exactly one sub dir, throw exception if there are more or less
> File f = FileUtils.globOneE("**/");
> // two parameter version allows to start recursive search in specified dir
> File f = FileUtils.globOneE(new File("."), "**/");
> {code}
> "\*\*" matches anything including file separators, "\*" matches anything
> excluding file separators, a final "/" indicates directory matching, a
> missing final slash indicates file matching. The function always traverses
> the entire directory hierarchy, starting at cwd by default (not counting
> optimizations). The search pattern is standardized, ie. "/" on all platforms,
> ie. "/" is not the platform file separator.
> Here is an example implementation:
