In order to prove that I had a signature on a commit I needed to use a this command line command:
$ git log --show-signature -1
I could not get Magit to display the signature I tried to use the Magit Key (l) and the -S switch.
But could not see the signature details.
Addressing questions to the answer from the magit author
I ran out of space in my comment so I edited my question to reply.
So I validated that each commit was signed using
git log --show-signature| cat in my shell in Emacs. Then I redid the command above and looked at individual rows to see the signature - but even when I hit RET as you say above, the signature still did not show up. I could also not see any evidence when all of the signatures were applied that any of them were signed.
How do I configure the expanded view of the signature so that the RET key will cause the details of the signature as the
--show-signature flag requires? I most want to be able to drill in with
RET and see exactly the text that is needed. I am concerned that I am missing details in magit that the shell shows properly.
magit-20200617.2306 is installed in the ~/.emacs.d/elpa/. directory
The signature now shows up in magit as a bright green color on the subject line of the commit message text
What remains is to add the details of the signature when a long form of the log message is used.
@tarsius I am fine with the signature details being omitted in the normal case when just one line is shown.
The bright green color is very useful to show that the commit is signed.
