Heavily prefer unix filter UI.
If you can't do it with filtering, it could mean you should split your function anyway.
Even function can use dash options and even usagef()
.
Reserved options are
-q|--quiet
, to turn off verbosity,-v|--verbose
, to turn on verbosity,-d|--debug
to turn on debug output (stderr).Do not think()
in functions.
Preferred capitalization in messages is:
all small for libs (debug/warn/die)
First cap for scripts
Message width:
think/warn/die: try hard to never exceed 72
debug: do what you must
always try to split message to fixed part, colon and before colon and the "data" part after the colon, e.g.:
file missing: /var/run/media/somebody/some-medium/some-long/path
instead of:
file /var/run/media/somebody/some-medium/some-long/path is missing
(even if you think that it will be short)
Be smart but honest: if you can default, default, otherwise be honest = fail
Don't talk. think()
instead.
