osrtool

A thing I did in an evening to quickly extract information from a osr file straight from your command line. Also a library to analyse osr files in Go. It can also be used to resample replays (to make them smaller) or to export a replay to headerless format, which cannot be read by osu! but it's used by the ripple stack.

Usage

λ osrtool --help
NAME:
   osrtool - Discover info about osr files without opening them in osu!

   osrtool [global options] command [command options] [arguments...]

VERSION:

   info     get metadata information about a replay file
   export   re-exports a replay (to headerless, or after resampling it, or both).
   help, h  Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --help, -h     show help (default: false)
   --version, -v  print the version (default: false)
