Subject: [PATCH 32/34] watch: support ~/.netrc via Net::Netrc
Date: Sat, 27 Jun 2020 10:03:58 +0000
Message-ID: <20200627100400.9871-33-e@yhbt.net> (raw)
In-Reply-To: <20200627100400.9871-1-e@yhbt.net>

While git-credential-netrc exists in git.git contrib/, it may
not be widely known or installed.  Net::Netrc is already a
standard part of most (if not all) Perl installations, so use it
directly if available.
