2 # Tips and Tricks for using notmuch with Emacs
4 One of the more popular notmuch message reading clients is
5 **notmuch.el**, an [emacs](http://www.gnu.org/software/emacs/) major
6 mode for interacting with notmuch. It is included in the notmuch
7 package (notmuch-emacs in Debian). This page goes over some usage
8 tips for using notmuch with Emacs.
14 Have a look at the [Howto](http://notmuchmail.org/howto/) for
15 prerequisites. Be sure you have done the general setup using the
18 To use the Notmuch emacs mode, first add the following line to your
21 (autoload 'notmuch "notmuch" "notmuch mail" t)
23 or if you always want to load notmuch when you start emacs:
27 Then, either run "emacs -f notmuch", or execute the command `M-x
28 notmuch` from within a running emacs.
30 ### <span id="notmuch_init_file"> Notmuch Emacs configuration file: </span>
34 After notmuch is loaded `notmuch-init-file` (typically
35 `~/.emacs.d/notmuch-config.el`) is checked out. If such file exists
36 it is loaded. Most emacs lisp based configuration not suitable via
37 customization can be put there instead of `~/.emacs`.
39 ## Navigating & reading mails
41 When first starting notmuch in emacs, you will be presented with the
42 notmuch "hello" page. If it exits with an error after writing
43 "Welcome to notmutch. You have" you need to do the basic notmuch setup
45 From here you can do searches, see lists of recent
46 searches, saved searches, message tags, help information, etc.
48 Executing a search will open a new buffer in `notmuch-search-mode`
49 displaying the search results. Each line in the search results
50 represents a message thread. Hitting the '?' key will show help for
53 In general, the 'q' will kill the current notmuch buffer and return
54 you to the previous buffer (sort of like a 'pop').
56 In search mode, navigating to a thread and hitting return will then
57 open a new buffer in `notmuch-show-mode`, which will show the actual
58 message contents of the thread.
62 In any notmuch mode, you can start a new message by hitting the 'm'
63 key. To reply to a message or thread, just hit the 'r' key.
65 When composing new messages, you will be entered in emacs's
66 `message-mode`, which is a powerful mode for composing and sending
67 messages. When in message mode, you can type `C-c ?` for help.
69 If you would like to use address autocompletion when composing
70 messages, see [address completion](#address_completion).
72 When you are ready to send a message, type `C-c C-c`. By default
73 message mode will use your sendmail command to send mail, so make sure
74 that works. One annoying standard configuration of message mode is
75 that it will hide the sent mail in your emacs frame stack, but it will
76 not close it. If you type several mails in an emacs session they will
77 accumulate and make switching between buffers more annoying. You can
78 avoid that behavior by adding `(setq message-kill-buffer-on-exit t)`
80 (or doing `M-x customize-variable<RET>message-kill-buffer-on-exit<RET>`)
81 which will really close the mail window after sending it.
85 Using the `M-x mml-attach-file` command, you can attach any file to be
86 sent with your mail. By default this command is bound to the menu item
87 *Attachments--Attach File* with the key binding `C-c C-a`. The
88 variable `mml-dnd-attach-options` (`M-x
89 customize-variable<RET>mml-dnd-attach-options<RET>`) can be set to
90 allow the prompting for various attachment options (such as
91 inline/attachment) if you want to do that.
93 For those who prefer a more graphical interface, you can also simply
94 drag and drop files from a file manager into a mail composition window
95 to have them attached. In Ubuntu this works without any modifications
96 if files are dragged from the file manager.
98 And for those who prefer working from command line, the following
99 script opens new emacs window with empty message and attaches files
100 mentioned as script arguments. (Note: The script expects that you have
101 `(server-start)` in your `.emacs` file.)
105 while [ $# -gt 0 ]; do
106 fullpath=$(readlink --canonicalize "$1")
107 attach_cmds="$attach_cmds (mml-attach-file \"$fullpath\")"
110 emacsclient -a '' -c -e "(progn (compose-mail) $attach_cmds)"
112 ## Controlling external handlers for attachements
114 You can choose e.g. which pdf viewer to invoke from notmuch-show mode by
115 adding a .mailcap file in your home directory. Here is an example:
117 application/pdf; /usr/bin/mupdf %s; test=test "$DISPLAY" != ""; description=Portable Document Format; nametemplate=%s.pdf
118 application/x-pdf; /usr/bin/mupdf %s; test=test "$DISPLAY" != ""; description=Portable Document Format; nametemplate=%s.pdf
120 ## Issues with Emacs 24
122 If notmuch-show-mode behaves badly for you in emacs 24.x try adding one of
124 (setq gnus-inhibit-images nil)
134 # Advanced tips and tweaks
136 ## Initial cursor position in notmuch 0.15 hello window
138 In notmuch version 0.15 emacs client the handling of cursor position in
139 notmuch hello window has been simplified to a version which suits best
142 Initially the cursor is positioned at the beginning of buffer.
144 Some users liked the "ancient" version where cursor was moved to the
145 first `Saved searches` button.
147 Add the following code to your notmuch emacs configuration file in
148 case you want this behaviour:
150 (add-hook 'notmuch-hello-refresh-hook
152 (if (and (eq (point) (point-min))
153 (search-forward "Saved searches:" nil t))
157 (if (eq (widget-type (widget-at)) 'editable-field)
158 (beginning-of-line)))))
160 ## Add a key binding to add/remove/toggle a tag
162 The `notmuch-{search,show,tree}-tag` functions are very useful for
163 making quick tag key bindings. The arguments to these functions have
164 changed as notmuch has evolved but the following should work on all
165 versions of notmuch from 0.13 on. These functions take a list of
166 tag changes as argument. For example, an argument of (list "+spam"
167 "-inbox") adds the tag spam and deletes the tag inbox. Note the
168 argument must be a list even if there is only a single tag change
169 e.g., use (list "+deleted") to add the deleted tag.
171 For instance, here's an example of how to make a key binding to add
172 the "spam" tag and remove the "inbox" tag in notmuch-show-mode:
174 (define-key notmuch-show-mode-map "S"
176 "mark message as spam"
178 (notmuch-show-tag (list "+spam" "-inbox"))))
180 You can do the same for threads in `notmuch-search-mode` by just
181 replacing "show" with "search" in the keymap and called functions, or
182 for messages in `notmuch-tree-mode` by replacing "show" by "tree". If
183 you want to tag a whole thread in `notmuch-tree-mode` use
184 `notmuch-tree-tag-thread` instead of `notmuch-tree-tag`.
186 You may also want the function in search mode apply to the all threads
187 in the selected region (if there is one). For notmuch prior to 0.17
188 this behaviour will occur automatically with the functions given
189 above. To get this behaviour on 0.17+ do the following:
191 (define-key notmuch-search-mode-map "S"
192 (lambda (&optional beg end)
193 "mark thread as spam"
194 (interactive (notmuch-search-interactive-region))
195 (notmuch-search-tag (list "+spam" "-inbox") beg end)))
197 The analogous functionality in notmuch-tree is currently missing.
199 The definitions above make use of a lambda function, but you could
200 also define a separate function first:
202 (defun notmuch-show-tag-spam ()
203 "mark message as spam"
205 (notmuch-show-add-tag (list "+spam" "-inbox")))
207 (define-key notmuch-show-mode-map "S" 'notmuch-show-tag-spam)
209 Here's a more complicated example of how to add a toggle "deleted"
212 (define-key notmuch-show-mode-map "d"
214 "toggle deleted tag for message"
216 (if (member "deleted" (notmuch-show-get-tags))
217 (notmuch-show-tag (list "-deleted"))
218 (notmuch-show-tag (list "+deleted")))))
220 ## Adding many tagging keybindings
222 If you want to have have many tagging keybindings, you can save the typing
223 the few lines of boilerplate for every binding (for versions before 0.12,
224 you will need to change notmuch-show-apply-tag-macro).
226 (eval-after-load 'notmuch-show
227 '(define-key notmuch-show-mode-map "`" 'notmuch-show-apply-tag-macro))
229 (setq notmuch-show-tag-macro-alist
231 '("m" "+notmuch::patch" "+notmuch::moreinfo" "-notmuch::needs-review")
232 '("n" "+notmuch::patch" "+notmuch::needs-review" "-notmuch::pushed")
233 '("o" "+notmuch::patch" "+notmuch::obsolete"
234 "-notmuch::needs-review" "-notmuch::moreinfo")
235 '("p" "-notmuch::pushed" "-notmuch::needs-review"
236 "-notmuch::moreinfo" "+pending")
237 '("P" "-pending" "-notmuch::needs-review" "-notmuch::moreinfo" "+notmuch::pushed")
238 '("r" "-notmuch::patch" "+notmuch::review")
239 '("s" "+notmuch::patch" "-notmuch::obsolete" "-notmuch::needs-review" "-notmuch::moreinfo" "+notmuch::stale")
240 '("t" "+notmuch::patch" "-notmuch::needs-review" "+notmuch::trivial")
241 '("w" "+notmuch::patch" "+notmuch::wip" "-notmuch::needs-review")))
243 (defun notmuch-show-apply-tag-macro (key)
245 (let ((macro (assoc key notmuch-show-tag-macro-alist)))
246 (apply 'notmuch-show-tag-message (cdr macro))))
248 ## Restore reply-to-all key binding to 'r'
250 Starting from notmuch 0.12 the 'r' key is bound to reply-to-sender instead of
251 reply-to-all. Here's how to swap the reply to sender/all bindings in show mode:
253 (define-key notmuch-show-mode-map "r" 'notmuch-show-reply)
254 (define-key notmuch-show-mode-map "R" 'notmuch-show-reply-sender)
258 (define-key notmuch-search-mode-map "r" 'notmuch-search-reply-to-thread)
259 (define-key notmuch-search-mode-map "R" 'notmuch-search-reply-to-thread-sender)
262 ## How to do FCC/BCC...
264 The Emacs interface to notmuch will automatically add an `Fcc`
265 header to your outgoing mail so that any messages you send will also
266 be saved in your mail store. You can control where this copy of the
267 message is saved by setting the variable `notmuch-fcc-dirs` which defines the
268 subdirectory relative to the `database.path` setting from your
269 notmuch configuration in which to save the mail. Enter a directory
270 (without the maildir `/cur` ending which will be appended
271 automatically). Additional information can be found as usual using:
273 M-x describe-variable notmuch-fcc-dirs
275 An additional variable that can affect FCC settings in some cases is
276 `message-directory`. Emacs message-mode uses this variable for
279 To customize both variables at the same time, use the fancy command:
281 M-x customize-apropos<RET>\(notmuch-fcc-dirs\)\|\(message-directory\)
283 This mechanism also allows you to select different folders to be
284 used for the outgoing mail depending on your selected `From`
285 address. Please see the documentation for the variable
286 `notmuch-fcc-dirs` in the customization window for how to arrange
289 ## How to customize `notmuch-saved-searches`
291 When starting notmuch, a list of saved searches and message counts is
292 displayed, replacing the older `notmuch-folders` command. The set of
293 saved searches displayed can be modified directly from the notmuch
294 interface (using the `[save]` button next to a previous search) or by
295 customising the variable `notmuch-saved-searches`.
297 An example setting for notmuch versions up to 0.17.x might be:
299 (setq notmuch-saved-searches '(("inbox" . "tag:inbox")
300 ("unread" . "tag:inbox AND tag:unread")
301 ("notmuch" . "tag:inbox AND to:notmuchmail.org")))
303 Starting from notmuch 0.18 the variable changed. It is backwards
304 compatible so the above will still work but the new style will be used
305 if you use customize and there are some new features available. The above would become
307 (setq notmuch-saved-searches '((:name "inbox" :query "tag:inbox")
308 (:name "unread" :query "tag:inbox AND tag:unread")
309 (:name "notmuch" :query "tag:inbox AND to:notmuchmail.org")))
311 The additional features are the possibility to set the search order
312 for the search, and the possibility to specify a different query for
313 displaying the count for the saved-search. For example
315 (setq notmuch-saved-searches '((:name "inbox"
317 :count-query "tag:inbox and tag:unread"
318 :sort-order 'oldest-first)))
320 specifies a single saved search for inbox, but the number displayed by
321 the search will be the number of unread messages in the inbox, and the
322 sort order for this search will be oldest-first.
324 Of course, you can have any number of saved searches, each configured
325 with any supported search terms (see "notmuch help search-terms"), and
326 in the new style variable they can each have different count-queries
329 Some users find it useful to add `and not tag:delete` to those
330 searches, as they use the `delete` tag to mark messages as
331 deleted. This causes messages that are marked as deleted to be removed
332 from the commonly used views of messages. Use whatever seems most
335 ## Viewing HTML messages with an external viewer
337 The Emacs client can generally display HTML messages inline using one of the
338 supported HTML renderers. This is controlled by the `mm-text-html-renderer`
341 Sometimes it may be necessary to display the message, or a single MIME part, in
342 an external browser. This can be done by `(notmuch-show-view-part)`, bound to
345 ## msmtp, message mode and multiple accounts
347 As an alternative to running a mail server such as sendmail or postfix
348 just to send email, it is possible to use
349 [msmtp](http://msmtp.sourceforge.net/). This small application will
350 look like `/usr/bin/sendmail` to a MUA such as emacs message mode, but
351 will just forward the email to an external SMTP server. It's fairly
352 easy to set up and it supports several accounts for using different
353 SMTP servers. The msmtp pages have several examples.
355 A typical scenario is that you want to use the company SMTP server
356 for email coming from your company email address, and your personal
357 server for personal email. If msmtp is passed the envelope address
358 on the command line (the -f/--from option) it will automatically
359 pick the matching account. The only trick here seems to be getting
360 emacs to actually pass the envelope from. There are a number of
361 overlapping configuration variables that control this, and it's a
362 little confusion, but setting these three works for me:
364 - `mail-specify-envelope-from`: `t`
366 - `message-sendmail-envelope-from`: `header`
368 - `mail-envelope-from`: `header`
370 With that in place, you need a `.msmtprc` with the accounts configured
371 for the domains you want to send out using specific SMTP servers and
372 the rest will go to the default account.
374 If you have a hard time getting the above to work for you, as I did,
375 it's also possible to add a message-send-mail-hook in your .emacs to
376 send the from header explicitly as an argument to msmtp as described
377 [here](http://www.emacswiki.org/cgi-bin/wiki/GnusMSMTP#toc2) on the
381 ## <span id="address_completion">Address completion when composing</span>
383 There are currently three solutions to this:
387 [bbdb](http://bbdb.sourceforge.net) is a contact database for emacs
388 that works quite nicely together with message mode, including
389 address autocompletion.
391 ### notmuch database as an address book
393 You can also use the notmuch database as a mail address book itself.
394 To do this you need a command line tool that outputs likely address
395 candidates based on a search string. There are currently four
398 * The python tool `notmuch_address.py` (`git clone
399 http://commonmeasure.org/~jkr/git/notmuch_addresses.git`) (slower, but
400 no compilation required so good for testing the setup)
403 [addrlookup](http://github.com/spaetz/vala-notmuch) (faster, but
404 needs compiling). The addrlookup binary needs to be compiled.
406 `http://github.com/spaetz/vala-notmuch/raw/static-sources/src/addrlookup.c`
409 cc -o addrlookup addrlookup.c `pkg-config --cflags --libs gobject-2.0` -lnotmuch
411 * Shell/fgrep/perl combination [nottoomuch-addresses.sh](https://github.com/domo141/nottoomuch/blob/master/nottoomuch-addresses.rst).
412 This tools maintains it's own address "database" gathered from email
413 files notmuch knows and search from that "database" is done by `fgrep(1)`.
415 * python/sqlite combination [notmuch-abook](https://github.com/guyzmo/notmuch-abook/)
416 This tools also maintains an address database in sqlite after harvesting
417 from notmuch. It also includes a vim plugin.
419 You can perform tab-completion using any of these programs.
420 Just add the following to your [notmuch init file](#notmuch_init_file):
422 (require 'notmuch-address)
423 (setq notmuch-address-command "/path/to/address_fetching_program")
424 (notmuch-address-message-insinuate)
428 [GooBook](http://code.google.com/p/goobook/) is a command-line tool for
429 accessing Google Contacts. Install and set it up according to its documentation.
431 To use GooBook with notmuch, use this wrapper script and set it up like the
435 goobook query "$*" | sed 's/\(.*\)\t\(.*\)\t.*/\2 \<\1\>/' | sed '/^$/d'
437 You can add the sender of a message to Google Contacts by piping the message
438 (`notmuch-show-pipe-message`) to `goobook add`.
442 git clone https://github.com/mmehnert/akonadimailsearch
444 Install the development packages for kdepim on your system.
445 Enter the cloned repository and create a build directory:
451 You will find the akonadimailsearch binary in the build/src directory. Copy it to ~/bin .
453 You can now add the following settings to your
454 [notmuch init file](#notmuch_init_file):
456 (require 'notmuch-address)
457 (setq notmuch-address-command "~/bin/akonadimailsearch")
458 (notmuch-address-message-insinuate)
460 ### Completion selection with helm
462 An address query might return multiple possible matches from which you
463 will have to select one. To ease this task, several different
464 frameworks in emacs support completion selection. One of them is
465 [helm](https://github.com/emacs-helm/helm). The following snippet
466 improves the out-of-the-box support for helm in notmuch as it enables
467 the required-match option and also does not ignore the first returned
470 (setq notmuch-address-selection-function
471 (lambda (prompt collection initial-input)
472 (completing-read prompt (cons initial-input collection) nil t nil 'notmuch-address-history)))
475 ## How to sign/encrypt messages with gpg
477 Messages can by signed using gpg by invoking
478 `M-x mml-secure-sign-pgpmime` (or `M-x mml-secure-encrypt-pgpmime`).
479 These functions are available via the standard `message-mode` keybindings
480 `C-c C-m s p` and `C-c C-m c p`. To sign outgoing mail by default, use the
481 `message-setup-hook` in your `.emacs` file:
483 ;; Sign messages by default.
484 (add-hook 'message-setup-hook 'mml-secure-sign-pgpmime)
486 This inserts the required `<#part sign=pgpmime>` into the beginning
487 of the mail text body and will be converted into a pgp signature
488 when sending (so one can just manually delete that line if signing
491 Alternatively, you may prefer to use `mml-secure-message-sign-pgpmime` instead
492 of `mml-secure-sign-pgpmime` to sign the whole message instead of just one
495 ### Troubleshooting message-mode gpg support
497 - If you have trouble with expired subkeys, you may have encountered
498 emacs bug #7931. This is fixed in git commit 301ea744c on
499 2011-02-02. Note that if you have the Debian package easypg
500 installed, it will shadow the fixed version of easypg included with
503 ## Reading and verifying encrypted and signed messages
505 Encrypted and signed mime messages can be read and verified with:
507 (notmuch-crypto-process-mime t)
509 Decrypting or verifying inline pgp messages can be done by selecting
510 an the inline pgp area and and using:
512 M-x epa-decrypt-region RET
514 ## Multiple identities using gnus-alias
516 [gnus-alias](http://www.emacswiki.org/emacs/GnusAlias) allows you to
517 define multiple identities when using `message-mode`. You can specify
518 the from address, organization, extra headers (including *Bcc*), extra
519 body text, and signature for each identity. Identities are chosen
520 based on a set of rules. When you are in message mode, you can switch
521 identities using gnus-alias.
525 - put `gnus-alias.el` on your load Emacs-Lisp load path (add new directory
526 to load path by writing `(add-to-list 'load-path "/some/load/path")` into
529 - Add the following to your `.emacs`
531 (autoload 'gnus-alias-determine-identity "gnus-alias" "" t)
532 (add-hook 'message-setup-hook 'gnus-alias-determine-identity)
534 Looking into `gnus-alias.el` gives a bit more information...
536 ### Example Configuration
538 Here is an example configuration.
540 ;; Define two identities, "home" and "work"
541 (setq gnus-alias-identity-alist
543 nil ;; Does not refer to any other identity
544 "John Doe <jdoe@example.net>" ;; Sender address
545 nil ;; No organization header
546 nil ;; No extra headers
547 nil ;; No extra body text
551 "John Doe <john.doe@example.com>"
553 (("Bcc" . "john.doe@example.com"))
555 "~/.signature.work")))
556 ;; Use "home" identity by default
557 (setq gnus-alias-default-identity "home")
558 ;; Define rules to match work identity
559 (setq gnus-alias-identity-rules)
560 '(("work" ("any" "john.doe@\\(example\\.com\\|help\\.example.com\\)" both) "work"))
561 ;; Determine identity when message-mode loads
562 (add-hook 'message-setup-hook 'gnus-alias-determine-identity)
564 When `gnus-alias` has been loaded (using autoload, require, *M-x load-library*
565 or *M-x load-file* (load-file takes file path -- therefore it can be used
566 without any `.emacs` changes)) the following commands can be used to get(/set)
567 more information (some of these have "extensive documentation"):
569 M-x describe-variable RET gnus-alias-identity-alist
570 M-x describe-variable RET gnus-alias-identity-rules
571 M-x describe-variable RET gnus-alias-default-identity
573 M-x customize-group RET gnus-alias RET
575 M-x gnus-alias-customize RET
577 The last two do the same thing.
579 See also the **Usage:** section in `gnus-alias.el`.
581 ## Resending (or bouncing) messages
583 Add the following to your [notmuch init file](#notmuch_init_file) to be able
584 to resend the current message in show mode.
586 (define-key notmuch-show-mode-map "b"
587 (lambda (&optional address)
588 "Bounce the current message."
589 (interactive "sBounce To: ")
590 (notmuch-show-view-raw-message)
591 (message-resend address)))
593 ## `notmuch-hello` refresh status message
595 Add the following to your [notmuch init file](#notmuch_init_file) to get a
596 status message about the change in the number of messages in the mail store
597 when refreshing the `notmuch-hello` buffer.
599 (defvar notmuch-hello-refresh-count 0)
601 (defun notmuch-hello-refresh-status-message ()
605 (car (process-lines notmuch-command "count"))))
606 (diff-count (- new-count notmuch-hello-refresh-count)))
608 ((= notmuch-hello-refresh-count 0)
609 (message "You have %s messages."
610 (notmuch-hello-nice-number new-count)))
612 (message "You have %s more messages since last refresh."
613 (notmuch-hello-nice-number diff-count)))
615 (message "You have %s fewer messages since last refresh."
616 (notmuch-hello-nice-number (- diff-count)))))
617 (setq notmuch-hello-refresh-count new-count))))
619 (add-hook 'notmuch-hello-refresh-hook 'notmuch-hello-refresh-status-message)
621 ## Replacing tabs with spaces in subject and header
623 Mailman mailing list software rewrites and rewraps long message subjects in
624 a way that causes TABs to appear in the middle of the subject and header
625 lines. Add this to your [notmuch init file](#notmuch_init_file) to replace
626 tabs with spaces in subject lines:
628 (defun notmuch-show-subject-tabs-to-spaces ()
629 "Replace tabs with spaces in subject line."
630 (goto-char (point-min))
631 (when (re-search-forward "^Subject:" nil t)
632 (while (re-search-forward "\t" (line-end-position) t)
633 (replace-match " " nil nil))))
635 (add-hook 'notmuch-show-markup-headers-hook 'notmuch-show-subject-tabs-to-spaces)
637 And in header lines (this will only work with the yet to be released
638 notmuch version 0.15):
640 (defun notmuch-show-header-tabs-to-spaces ()
641 "Replace tabs with spaces in header line."
642 (setq header-line-format
643 (notmuch-show-strip-re
644 (replace-regexp-in-string "\t" " " (notmuch-show-get-subject)))))
646 (add-hook 'notmuch-show-hook 'notmuch-show-header-tabs-to-spaces)
648 ## Hiding unread messages in notmuch-show
650 I like to have an inbox saved search, but only show unread messages when they
651 view a thread. This takes two steps:
654 [this patch from Mark Walters](http://notmuchmail.org/pipermail/notmuch/2012/010817.html)
655 to add the `notmuch-show-filter-thread` function.
656 1. Add the following hook to your emacs configuration:
658 (defun expand-only-unread-hook () (interactive)
660 (open (notmuch-show-get-message-ids-for-open-messages)))
661 (notmuch-show-mapc (lambda ()
662 (when (member "unread" (notmuch-show-get-tags))
665 (let ((notmuch-show-hook (remove 'expand-only-unread-hook notmuch-show-hook)))
666 (notmuch-show-filter-thread "tag:unread")))))
668 (add-hook 'notmuch-show-hook 'expand-only-unread-hook)
670 ## Changing the color of a saved search based on some other search
672 I like to have a saved search for my inbox, but have it change color when there
673 are thread with unread messages in the inbox. I accomplish this with the
674 following code in my emacs config:
676 (defun color-inbox-if-unread () (interactive)
678 (goto-char (point-min))
679 (let ((cnt (car (process-lines "notmuch" "count" "tag:inbox and tag:unread"))))
680 (when (> (string-to-number cnt) 0)
682 (when (search-forward "inbox" (point-max) t)
683 (let* ((overlays (overlays-in (match-beginning 0) (match-end 0)))
684 (overlay (car overlays)))
686 (overlay-put overlay 'face '((:inherit bold) (:foreground "green")))))))))))
687 (add-hook 'notmuch-hello-refresh-hook 'color-inbox-if-unread)
689 ## Linking to notmuch messages and threads from the Circe IRC client
691 [Circe](https://github.com/jorgenschaefer/circe/wiki) is an IRC client for emacs.
692 To have clickable buttons for notmuch messages and threads, add the following to
693 `lui-buttons-list` (using, e.g. M-x customize-variable)
695 ("\\(?:id\\|mid\\|thread\\):[0-9A-Za-z][0-9A-Za-z.@-]*" 0 notmuch-show 0)
697 If you have notmuch-pick installed, it works fine for this as well.
699 ## Linking to notmuch messages from org-mode
701 Support for linking to notmuch messages is distributed with org-mode,
702 but as a contrib file, so you might have to work a bit to load it.
704 In Debian and derivatives,
706 (add-to-list 'load-path "/usr/share/org-mode/lisp")
710 (require 'org-notmuch)
712 In general it is nice to have a key for org-links (not just for notmuch). For example
714 (define-key global-map "\C-cl" 'org-store-link)
716 ## Viewing diffs in notmuch
718 The following code allows you to view an inline patch in diff-mode
719 directly from notmuch. This means that normal diff-mode commands like
720 refine, next hunk etc all work.
722 (defun my-notmuch-show-view-as-patch ()
723 "View the the current message as a patch."
725 (let* ((id (notmuch-show-get-message-id))
726 (subject (concat "Subject: " (notmuch-show-get-subject) "\n"))
727 (diff-default-read-only t)
728 (buf (get-buffer-create (concat "*notmuch-patch-" id "*")))
729 (map (make-sparse-keymap)))
730 (define-key map "q" 'notmuch-kill-this-buffer)
731 (switch-to-buffer buf)
732 (let ((inhibit-read-only t))
735 (insert (notmuch-get-bodypart-internal id 1 nil)))
736 (set-buffer-modified-p nil)
738 (lexical-let ((new-ro-bind (cons 'buffer-read-only map)))
739 (add-to-list 'minor-mode-overriding-map-alist new-ro-bind))
740 (goto-char (point-min))))
742 and then this function needs to bound into the keymap with something like
744 (define-key 'notmuch-show-mode-map "D" 'my-notmuch-show-view-as-patch)
