This modifies the "docker help" text so that it is no wider than 80 chars and each description fits on one line. This will also try to use ~ when possible Added a test to make sure we don't go over 80 chars again. Added a test to make sure we use ~ Applied rules/tests to all docker commands - not just main help text Closes #10214 Signed-off-by: Doug Davis <dug@us.ibm.com> Upstream-commit: 2203b37733e76d653cfe3b0ec5870786076adce7 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
