Arno Unkrig commented on COMPRESS-292:
--------------------------------------
This looks really good! As far as I can see, everything I need is there:
* "All" archive formats
* Get archive format by name
> Add support for virtual formats

> Issue Type: New Feature
> Components: Archivers, Compressors
> Affects Versions: 1.9
> Reporter: Arno Unkrig

> Hello COMPRESS team!
> Most applications know at compile-time which archive/compression format they
> want to use, but some don't. {{ArchiveStreamFactory}} and
> {{CompressorStreamFactory}} provide minimal support for runtime format
> processing, but more comprehensive handling would be greatly appreciated.
> I propose the addition of the {{ArchiveFormat}} and {{CompressionFormat}}
> interfaces, together with their factories, to implement the following:
> * Detection of archive/compression formats from contents, file name or format
> name
> * Conversion of archive/compressed file names, e.g. "mydir" => "mydir.tar" =>
> "mydir.tar.gz"
> * Runtime extensibility through format auto-registration; factory method
> {{allFormats()}} informs which formats are available
> * Writing archive entries without knowing the archive type at compile-time
> * Automated conversion of archive entries when copying from one format to
> another
> A sample design is available
> [here|https://svn.code.sf.net/p/loggifier/code/trunk/de.unkrig.commons.file/src/de/unkrig/commons/file/org/apache/commons/compress/].
> If you like it, I would gladly donate it to the the project. The current
> license is "New BSD", which is (hopefully) compatible with yours.
> Regards,
> Arno Unkrig
