This patch obsoletes id:1352565719-12397-1-git-send-email-damien.cassou@gmail.com [PATCH 1/4] emacs: Add a thread's tags to emacs header-line [PATCH 2/4] emacs: Make tags in header-line clickable [PATCH 3/4] emacs: Make tags that appear in `notmuch-show' clickable [PATCH 4/4] emacs: Add unit-tests for clickable tags in notmuch-show This patch makes clickable all tags that appear in notmuch-show buffers. Each tag is a link to open a new notmuch-search buffer for this tag. Additionally, the buffer's header-line now shows the thread's tags (clickable only if the `header-button' library is loaded or loadable). This patch is the first one of an upcoming series whose goal is to integrate notmuch-labeler into notmuch. See the following for more details: https://github.com/DamienCassou/notmuch-labeler With respect to v2, I took care of the comments you made: - The header-button library is not attached to the patch anymore. The tags in the header-line are always displayed but made clickable only if the library is loaded or loadable. - The large patch is separated into a series of 4 smaller patches.
