An earlier commit was causing docker windows CLI build to not to pick up the shorthand form for home directory (`%USERPROFILE%`) shown in when `docker --help` is executed. Fixing that bug and making the if statement concise and clear. Signed-off-by: Ahmet Alp Balkan <ahmetalpbalkan@gmail.com> Upstream-commit: 802c90500073ad79e5a6520402ef2a7268c824b7 Component: engine
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
