Open mime attachments in Emacs
As shown in a previous post, Emacs has some nice email readers. However, the default handling of most attachments (MIME types in traditional programming speak) is just to save the file. I have configured Emacs to rely on Windows for opening some types of attachments that I find often. As an example, I show below how to open PDFs and Word files, although it can be extended to other file types. Place this code in your Emacs' init.el file.
(ctree-set-calist-strictly
'mime-acting-condition
'((mode . "play")
(type . application)
(subtype . pdf)
(method . jjgr-default-mime-open)))
(ctree-set-calist-strictly
'mime-acting-condition
'((mode . "play")
(type . application)
(subtype . vnd.openxmlformats-officedocument.wordprocessingml.document)
(method . jjgr-default-mime-open)))
(defun jjgr-default-mime-open (&optional a b)
(let* ((entity (get-text-property (point) 'mime-view-entity))
(name (mime-entity-safe-filename entity))
(filename (concat (getenv "HOMEDRIVE")
(getenv "HOMEPATH")
"\\Downloads\\"
name)))
(mime-write-entity-content entity filename)
(print `(start-process "cmd.exe" "*Play*" "cmd.exe" ,filename))
(start-process "cmd.exe" nil "cmd.exe" "/c" "start" "/b" filename)))
