Can use https://justine.lol/cosmopolitan/documentation.html#systemvpe when using Cosmopolitan. Otherwise use system on Linux.

Apparently, the __COSMOPOLITAN__ macro is defined when compiled with Cosmopolitan.

Linux and MacOS has system available. Windows apparently has _spawn functions. It probably is ideal to use _spawnvpe which has args similar to Cosmopolitan's systemvpe.

The current plan is to use https://justine.lol/cosmopolitan/documentation.html#pipe2 , https://justine.lol/cosmopolitan/documentation.html#posix_spawnp , and https://justine.lol/cosmopolitan/documentation.html#posix_spawn_file_actions_adddup2 for Unix and Cosmopolitan implementations. The Windows implementation will be done later.

In other words, the de/compressor cmds should accept file data from stdin and print compressed data to stdout.

As of be67425d21 , compressing into an archive works. This also set up some stuff for decompressing as well, so it shouldn't be too hard to do the decompressing part.

Closing this issue, as the rest is covered by #4 .
