\r
55 Currently, notmuch has an address completion mechanism that requires
\r
56 external command to provide completion candidates. This patch adds a
\r
57 completion mechanism inspired by https://github.com/tjim/nevermore,
\r
58 which is implemented in Emacs lisp only.
\r
60 The core of the new mechanism is the function notmuch-address-harvest
\r
61 that collects the completion candidates from the notmuch database and
\r
62 stores them in notmuch-address-completions variable.
\r
63 notmuch-address-harvest is called on the first entry to message-mode
\r
64 and runs asychnornously so that the user doesn't have to wait for it
\r
65 to complete while composing the message. The
\r
66 notmuch-address-completions variable is used in message-mode as a
\r
67 source of completion candidates. Currently, there are two ways how the
\r
68 notmuch-address-completions variable is used.
\r
70 First, preexisting address completion mechanism is extended to use
\r
71 notmuch-address-completions in addition to the external command. This
\r
72 new behavior is configured by setting notmuch-address-command to nil,
\r
73 which is the new default. Note that this may *BREAK EXISTING SETUPS*
\r
74 when the user used external command named "notmuch-addresses", i.e.
\r
75 the previous default. The result will be that the user will use the
\r
76 new mechanism instead of the his command. I believe that many users
\r
77 may not even recognize this because the new mechanism works the same
\r
78 as http://commonmeasure.org/~jkr/git/notmuch_addresses.git and perhaps
\r
79 also as other commands suggested at
\r
80 http://notmuchmail.org/emacstips/#address_completion.
\r
82 Second way of using notmuch-address-completions is notmuch-company.el.
\r
83 This presents the possible completions in a nice popup box after a
\r
84 short typing delay but requires company-mode to be installed.
\r
87 - Use of notmuch-parser.el instead of the custom parser in the
\r
88 original code. The notmuch parser is slightly faster.
\r
89 - Use of functions in notmuch-query.el instead of functions in the
\r
90 original code with almost the same functionality.
\r
91 - Integrated with existing completion mechanism in notmuch.
\r
92 - notmuch-company.el was moved from emacs/contrib to emacs and
\r
93 no-byte-compile directive was added to it.
\r
94 - Aligned with notmuch naming conventions.
\r
95 - Documented bugs found in notmuch-company.el
