-## Controlling external handlers for attachements
+## Controlling external handlers for attachments
You can choose e.g. which pdf viewer to invoke from notmuch-show mode by
adding a .mailcap file in your home directory. Here is an example:
application/pdf; /usr/bin/mupdf %s; test=test "$DISPLAY" != ""; description=Portable Document Format; nametemplate=%s.pdf
application/x-pdf; /usr/bin/mupdf %s; test=test "$DISPLAY" != ""; description=Portable Document Format; nametemplate=%s.pdf
+### Convert ".pdf" and ".docx" to text and pop to buffer
+
+Add the following (hacky but effective!) code to `.emacs.d/notmuch-config.el`;
+the overwritten `defcustom` will change action when pressing RET on top of an
+attachment; ".pdf" and ".docx" attachments are converted to text (using
+"pdf2text" and "docx2txt.pl" commands to do the conversion), saving to file
+(the default action of `notmuch-show-part-button-default-action`) is offered
+to attachments of other types.
+
+ (defun user/mm-pipe-- (handle cmd)
+ ;; conveniently, '-' '-' a args to pdftotext and docx2txt.pl work fine

## Overwriting the sender address
If you want to always use the same sender address, then the following
(define-key notmuch-search-mode-map "S"
(lambda (&optional beg end)
"mark thread as spam"
- (interactive (notmuch-search-interactive-region))
+ (interactive (notmuch-interactive-region))
(notmuch-search-tag (list "+spam" "-inbox") beg end)))
The analogous functionality in notmuch-tree is currently missing.
(define-key notmuch-show-mode-map "r" 'notmuch-show-reply)
(define-key notmuch-show-mode-map "R" 'notmuch-show-reply-sender)
-And in search mode:

## How to do FCC/BCC...
`notmuch-fcc-dirs` in the customization window for how to arrange
this.
+The `notmuch-fcc-dirs` variable is only taken into account when mails
+are composed using `notmuch-mua-mail`. If you want to use the notmuch
+mail user agent by default, the `mail-user-agent` needs to be
+customized to use the `notmuch-user-agent`.
+
## How to customize `notmuch-saved-searches`
When starting notmuch, a list of saved searches and message counts is
an external browser. This can be done by `(notmuch-show-view-part)`, bound to
`. v` by default.
+This command will try to view the message part the point is on with an
+external viewer. The mime-type of the part will determine what viewer
+will be used. Typically a 'text/html' part will be send to your
+browser.
+
+The configuration for this is kept in so called `mailcap`
+files. (typically the file is `~/.mailcap` or `/etc/mailcap`) If the
+wrong viewer is started or something else goes wrong, there's a good
+chance something needs to be adapted in the mailcap configuration.
+
+For Example: The `copiousoutput` setting in mailcap files needs to be
+removed for some mime-types to prevent immediate removal of temporary
+files so the configured viewer can access them.

## How to sign/encrypt messages with gpg
-Messages can by signed using gpg by invoking
+Messages can be signed using gpg by invoking
`M-x mml-secure-sign-pgpmime` (or `M-x mml-secure-encrypt-pgpmime`).
These functions are available via the standard `message-mode` keybindings
-`C-c C-m s p` and `C-c C-m c p`. To sign outgoing mail by default, use the
-`message-setup-hook` in your `.emacs` file:
+`C-c C-m s p` and `C-c C-m c p`.
+
+In Emacs 28 you will be asked whether to sign the message using the
+sender and are offered to remember your choice. In Emacs 27 you will
+get a slightly misleading error and have to manually add the following
+line to you init file. Older Emacsen just do this unconditionally.
+
+ (setq mml-secure-openpgp-sign-with-sender t)
+
+To sign outgoing mail by default, use the `message-setup-hook` in your
+init file:
;; Sign messages by default.
(add-hook 'message-setup-hook 'mml-secure-sign-pgpmime)
(setq notmuch-crypto-process-mime t)

+Decrypting inline pgp messages can be done by selecting an the inline pgp area
+and using:
M-x epa-decrypt-region RET
+Verifying of inline pgp messages is not supported directly ([reasons
+here](https://dkg.fifthhorseman.net/notes/inline-pgp-harmful/)). You can still
+verify a part using
+
+ M-x notmuch-show-pipe-part RET gpg --verify RET
+
## Multiple identities using gnus-alias
[gnus-alias](http://www.emacswiki.org/emacs/GnusAlias) allows you to
;; Use "home" identity by default
(setq gnus-alias-default-identity "home")
;; Define rules to match work identity
- (setq gnus-alias-identity-rules)
- '(("work" ("any" "john.doe@\\(example\\.com\\|help\\.example.com\\)" both) "work"))
+ (setq gnus-alias-identity-rules
+ '(("work" ("any" "john.doe@\\(example\\.com\\|help\\.example.com\\)" both) "work")))
;; Determine identity when message-mode loads
(add-hook 'message-setup-hook 'gnus-alias-determine-identity)
## Multiple identities (and more) with message-templ
Another option for multiple identities is
-[message-templ](http://pivot.cs.unb.ca/git?p=message-templ.git;a=summary)
+[message-templ](http://git.tethera.net/message-templ.git)
(also a available in marmalade). This provides roughly the same
facilities as wanderlust's template facility.
See
-[example.emacs.el](http://pivot.cs.unb.ca/git?p=message-templ.git;a=blob;f=example.emacs.el;hb=HEAD)
+[example.emacs.el](https://git.tethera.net/message-templ.git/tree/example.emacs.el)
for some simple examples of usage.
## Resending (or bouncing) messages
(add-hook 'notmuch-show-markup-headers-hook 'notmuch-show-subject-tabs-to-spaces)
-And in header lines (this will only work with the yet to be released
-notmuch version 0.15):
+And in header lines:
(defun notmuch-show-header-tabs-to-spaces ()
"Replace tabs with spaces in header line."
(add-to-list 'load-path "/usr/share/org-mode/lisp")
+In NixOS, using `emacsWithPackages (epkgs: [ epkgs.orgPackages.org-plus-contrib ])`,
+
+ (loop for p in load-path
+ do (if (file-accessible-directory-p p)
+ (let ((m (directory-files-recursively p "^ol-notmuch.el$")))
+ (if m (add-to-list 'load-path (file-name-directory (car m)))))))
+
Then
- (require 'org-notmuch)
+ (require 'ol-notmuch)
In general it is nice to have a key for org-links (not just for notmuch). For example
- (define-key global-map "\C-cl" 'org-store-link)
+ (define-key global-map "\C-c l" 'org-store-link)
+
+If you're using `use-package` the package can be loaded using the following:
+
+```emacs-lisp
+(use-package ol-notmuch
+ :ensure t
+ :bind
+ ("C-c l" . org-store-link))
+```
+
+Note the package was renamed from `org-notmuch` to `ol-notmuch` in recent
+versions of org-mode. If you're using an old version of notmuch you might want
+to `(require 'org-notmuch)` instead.

Replacing `http://patchwork.example.com/patch/`, `/path/to/pwclient`, and
-`the-project` appropiately. You should now be able to stash the Patchwork URL
+`the-project` appropriately. You should now be able to stash the Patchwork URL
using `c l`.
Going further, if the patch has been committed, you can get the commit hash with
"-m" (concat "<" message-id ">")
"-n" "1"
"-f" "%{commit_ref}"))))
+
+## Never forget attachments
+
+Very often we forget to actually attach the file when we send an email
+that's supposed to have an attachment. Did this never happen to you?
+If not, then it will.
+
+Since version 0.29 Notmuch includes the `notmuch-mua-attachment-check`
+function. This function checks whether a message references an
+attachment and if it finds none it asks for confirmation before
+sending the message. The function is meant to be added to the
+`message-send-hook`, like so:
+
+ (add-hook 'message-send-hook 'notmuch-mua-attachment-check)
+
+The "customize"able variable `notmuch-mua-attachment-regexp` controls
+how reference to an attachment are identified. By default, it
+identifies English and French terms. For example, the following makes
+it recognise English and Portuguese terms:
+
+ (setq-default notmuch-mua-attachment-regexp
+ "\\b\\(attach\\|attachment\\|attached\\|anexo\\|anexado\\)\\b")
+
+
+## Avoid forgetting the subject
+
+It happens that we forget to enter the Subject line, particularly when
+we leave that to the end. It's easy to write a function that checks
+whether the Subject is empty, and add it to `message-send-hook` to get
+confirmation:
+
+ (defun my-notmuch-mua-empty-subject-check ()
+ "Request confirmation before sending a message with empty subject"
+ (when (and (null (message-field-value "Subject"))
+ (not (y-or-n-p "Subject is empty, send anyway? ")))
+ (error "Sending message cancelled: empty subject.")))
+ (add-hook 'message-send-hook 'my-notmuch-mua-empty-subject-check)
+
+
+## Applying patches to git repositories
+
+The `notmuch-extract-thread-patches` and
+`notmuch-extract-message-patches` commands from the `elpa-mailscripts`
+package in Debian (and its derivatives) can do this for you.
+
+## Allow content preference based on message context
+
+The preference for which sub-part of a multipart/alternative part is shown is
+globally set. For example, if you prefer showing the html version over the text
+based, you can set:
+
+ (setq notmuch-multipart/alternative-discouraged '("text/plain" "text/html"))
+
+However, sometimes you might want to adapt your preference depending on the
+context. You can override the default settings on a per-message basis by
+providing a function that has access to the message and which returns the
+discouraged type list. For example:
+
+ (defun my/determine-discouraged (msg)
+ (let* ((headers (plist-get msg :headers))
+ (from (or (plist-get headers :From) "")))
+ (cond
+ ((string-match "whatever@mail.address.com" from)
+ '("text/plain"))
+ (t
+ '("text/html" "multipart/related")))))
+
+ (setq notmuch-multipart/alternative-discouraged
+ 'my/determine-discouraged)
+
+This would discourage text/html and multipart/related generally, but discourage
+text/plain should the message be sent from whatever@mail.address.com.
+
+## See the recipient address instead of your address when listing sent messages
+
+If you like to see your sent messages in unthreaded view, by default you will
+see your address in the authors column, which is maybe not what you want. The
+following code allows for showing the recipients if your email address (an
+arbitrary address, whatever@mail.address.com in the example) is included in the
+From field.
+
+ (defun my/notmuch-unthreaded-show-recipient-if-sent (format-string result)
+ (let* ((headers (plist-get result :headers))
+ (to (plist-get headers :To))
+ (author (plist-get headers :From))
+ (face (if (plist-get result :match)
+ 'notmuch-tree-match-author-face
+ 'notmuch-tree-no-match-author-face)))
+ (propertize
+ (format format-string
+ (if (string-match "whatever@mail.address.com" author)
+ (concat "↦ " (notmuch-tree-clean-address to))
+ (notmuch-tree-clean-address to)
+ author))
+ 'face face)))
+
+ (setq notmuch-unthreaded-result-format
+ '(("date" . "%12s ")
+ (my/notmuch-unthreaded-show-recipient-if-sent . "%-20.20s")
+ ((("subject" . "%s"))
+ . " %-54s ")
+ ("tags" . "(%s)")))
