Subject: [PATCH v2 2/7] test-lib: parse some --options earlier
Date: Sun, 9 Dec 2018 23:56:23 +0100 [thread overview]
Message-ID: <20181209225628.22216-3-szeder.dev@gmail.com> (raw)
In-Reply-To: <20181209225628.22216-1-szeder.dev@gmail.com>
'test-lib.sh' looks for the presence of certain options like '--tee'
and '--verbose-log', so it can execute the test script again to save
its standard output and error. This happens way before the actual
option parsing loop, and the condition looking for these options looks
a bit odd, too. This patch series will add two more options to look
out for, and, in addition, will have to extract these options' stuck
arguments (i.e. '--opt=arg') as well.
Add a proper option parsing loop to check these select options early
in 'test-lib.sh', making this early option checking more readable and
keeping those later changes in this series simpler. Use a 'for opt in
"$@"' loop to iterate over the options to preserve "$@" intact, so
options like '--verbose-log' can execute the test script again with
all the original options.
As an alternative, we could parse all options early, but there are
options that do require an _unstuck_ argument, which is tricky to
handle properly in such a for loop, and the resulting complexity is,
in my opinion, worse than having this extra, partial option parsing
loop.
