From 05aa049e2c314731385e1d18b5fd6e1f1e63ea8f Mon Sep 17 00:00:00 2001 From: "Andreas J. Reichel" Date: Fri, 21 Apr 2017 14:11:42 +0200 Subject: wic: Use argparse instead of optparse * optparse is deprecated and will not be developed further (see: https://docs.python.org/2/library/optparse.html) * argparse supports subcommands, which simplifies definition of arguments and options * reimplement help mechanism through sub-subcommands [YOCTO #9636] (From OE-Core rev: 4fe9635c72a6ee1becc47d832ab54724176ee811) Signed-off-by: Andreas Reichel Signed-off-by: Jan Kiszka Signed-off-by: Daniel Wagner Signed-off-by: Ed Bartosh Signed-off-by: Ross Burton Signed-off-by: Richard Purdie --- scripts/lib/wic/help.py | 23 ++++++++++++++++------- 1 file changed, 16 insertions(+), 7 deletions(-) (limited to 'scripts/lib/wic/help.py') diff --git a/scripts/lib/wic/help.py b/scripts/lib/wic/help.py index d6e027d253..74db05cb94 100644 --- a/scripts/lib/wic/help.py +++ b/scripts/lib/wic/help.py @@ -56,7 +56,7 @@ def wic_help(args, usage_str, subcommands): """ Subcommand help dispatcher.
