Dear All, I sent this to the list a couple of years back, but now that things are moving again, and there are new eyes on the list, I thought I'd send it again. I believe I'm the only person to use this (and might well continue to be so) but I've been using it for a couple of years without any problems, and it has made using message mode a lot more convenient. As far as I know, this doesn't intersect with the recent security problems pointed out in mml-mode, but I could be wrong. My issue was this: the handling of (outgoing) attachments in message-mode left a lot to be desired. MML's markup can be confusing, and can easily be edited by mistake. Thus: tach.el. Tach is a minor mode that adds mutt-like attachment handling to message mode. It's not notmuch specific, but I wrote it to use with notmuch, and I thought it might be of use to some on the list. You can find tach.el attached to this email. To use tach, put tach.el in your load-path, and add the following to your .emacs: (require 'tach) (add-hook 'message-mode-hook 'tach-minor-mode) Now when you type "C-c C-a" in message-mode, you should get a new window with an attachment list. In that window, you can add and delete attachments using `+' and `-', and scroll through them using the arrow keys or the emacs direction commands. tach.el will convert the attachments into MML markup as a last step before sending. Hopefully you should never have to deal with it by hand. Some details: tach actually makes a numerical list at the bottom of the message itself, separated by a custom separator. The message is narrowed to above this separator, and the attachment window is an indirect buffer narrowed to the region below the separator. The separator is erased when the messages are translated to mml markup at the end. This has remained at its earliest stages, and the usual disclaimers apply. It certainly needs more a lot more commenting and documentation. But I thought it might be useful, or at least fun to play around with. And it might fill a niche for some users, as notmuch's popularity continues to grow. Best, Jesse
