From: Daniel Kahn Gillmor Date: Tue, 19 Dec 2017 16:40:54 +0000 (-0500) Subject: cli/show: make --decrypt take a keyword. X-Git-Tag: 0.26_rc1~14 X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=8ea4a99d74737929f58568505e41c94f65a14743 cli/show: make --decrypt take a keyword. We also expand tab completion for it, update the emacs bindings, and update T350, T357, and T450 to match. Make use of the bool-to-keyword backward-compatibility feature. --- diff --git a/completion/notmuch-completion.bash b/completion/notmuch-completion.bash index adf64a0a..17f3c5ec 100644 --- a/completion/notmuch-completion.bash +++ b/completion/notmuch-completion.bash @@ -517,10 +517,14 @@ _notmuch_show() COMPREPLY=( $( compgen -W "text json sexp mbox raw" -- "${cur}" ) ) return ;; - --exclude|--body|--decrypt) + --exclude|--body) COMPREPLY=( $( compgen -W "true false" -- "${cur}" ) ) return ;; + --decrypt) + COMPREPLY=( $( compgen -W "true auto false" -- "${cur}" ) ) + return + ;; esac ! $split && diff --git a/doc/man1/notmuch-show.rst b/doc/man1/notmuch-show.rst index 64caa7a6..7d2b38cb 100644 --- a/doc/man1/notmuch-show.rst +++ b/doc/man1/notmuch-show.rst @@ -115,22 +115,27 @@ Supported options for **show** include supported with --format=json and --format=sexp), and the multipart/signed part will be replaced by the signed data. - ``--decrypt`` - Decrypt any MIME encrypted parts found in the selected content - (ie.
