Subject: Default true boolean zstyle
Date: Fri, 14 Oct 2016 08:27:40 +0200	[thread overview]
Message-ID: <CAKc7PVDZJH28+x-FPNB3tKxP7z1yY73KJAqjnX1tTQjgegdH4Q@mail.gmail.com> (raw)

Hello,
following code explains:

% zstyle -b ":test-context" test_var test_var || test_var="yes"
% echo $test_var
yes
% zstyle ":test-context" test_var 0
% zstyle -b ":test-context" test_var test_var || test_var="yes"
% echo $test_var
yes

Apparently, zstyle -b returns false when the boolean being read is
false. So "|| test_var=yes" is triggered, and the value is
overwritten. Following way also doesn't do what's expected:

% test_var="yes"
% zstyle -b ":test-context" test_var test_var
% echo $test_var
no

Is there a way to have default-true boolean with zstyle?

Best regards,
Sebastian Gniazdowski
