0.21.0

MAJOR NEW FEATURES

• added apply geocode caching, more than doubling performance in the geocode benchmark.
• added --random and --seed options to sort command from @pjsier, enabling reproducible, randomized "scrambling" of CSVs.
• Bash shell qsv tab completion
• additional apply operations subcommands:
  • Match Trim operations - enables trimming of more than just whitespace, but also of multiple trim characters in one pass (Example):
    • mtrim: Trims --comparand matches left & right of the string (trim_matches wrapper)
    • mltrim: Left trim --comparand matches (trim_start_matches wrapper)
    • mrtrim: Right trim --comparand matches (trim_end_matches wrapper)
  • replace: Replace all matches of a pattern (using --comparand)
    with a string (using --replacement) (Std::String replace wrapper).
  • regex_replace: Replace the leftmost-first regex match with --replacement (regex replace wrapper).
  • titlecase - capitalizes English text using Daring Fireball titlecase style

  • censor_check: check if profanity is detected (boolean) Examples
  • censor: profanity filter
• added parameter validation to apply operations subcommands
• added more robust parameter validation to apply command by leveraging docopt

More benchmark script improvements:

• allow binary to be changed, so users can benchmark xsv and other xsv forks by simply replacing the $bin shell variable
• now uses a much larger data file - a 1M row, 512 mb, 41 column sampling of NYC's 311 data
