lzo support

[angleman]

• Check support from p7zip
• Find source and compile it for 10.8+
• Check compatibility of current GUI options
• Check lz4 Add lz4 support #85

Any possibility of adding lzo compression support? I ended up buying Snowflower Arc for lzo support but I'd rather use Keka as I prefer it's interface and ability to launch from the context menu.

I was researching some info, might be possible, also LZ4. No timeline yet.

By the way, even in the lzo website it states:

If you need better compression you should take a look at the excellent zlib library. zlib is slower and needs more memory, though.

For even better compression consider using libbzip2 which is distributed with the bzip2 file compressor.

What are the reasons you prefer lzo instead bzip2? Just curious, as I've never used it myself.
