Package mflag (aka multiple-flag) implements command-line flag parsing.
It's an hacky fork of the official golang package
It adds:
-
both short and long flag version
./example -s red
./example --string blue
-
multiple names for the same option
$>./example -h
Usage of example:
-s, --string="": a simple string
It is very flexible on purpose, so you can do things like:
$>./example -h
Usage of example:
-s, -string, --string="": a simple string
Or:
$>./example -h
Usage of example:
-oldflag, --newflag="": a simple string
You can also hide some flags from the usage, so if we want only --newflag
:
$>./example -h
Usage of example:
--newflag="": a simple string
$>./example -oldflag str
str
See example.go for more details.
