Emacs: Add address completion mechanism implemented in elisp Currently, notmuch has an address completion mechanism that requires external command to provide completion candidates. This commit adds a completion mechanism inspired by https://github.com/tjim/nevermore, which is implemented in Emacs lisp only. The preexisting address completion mechanism, activated by pressing TAB on To/Cc lines, is extended to use the new mechanism when notmuch-address-command to 'internal, which is the new default. The core of the new mechanism is the function notmuch-address-harvest, which collects the completion candidates from the notmuch database and stores them in notmuch-address-completions variable. The address harvesting can run either synchronously (same as with the previous mechanism) or asynchronously. When the user presses TAB for the first time, synchronous harvesting limited to user entered text is performed. If the entered text is reasonably long, this operation is relatively fast. Then, asynchronous harvesting over the full database is triggered. This operation may take long time (minutes on rotating disk). After it finishes, no harvesting is normally performed again and subsequent completion requests use the harvested data cached in memory. Completion cache is updated after 24 hours. Note that this commit restores (different) completion functionality for users when the user used external command named "notmuch-addresses", i.e. the old default. The result will be that the user will use the new mechanism instead of this command. I believe that many users may not even recognize this because the new mechanism works the same as http://commonmeasure.org/~jkr/git/notmuch_addresses.git and perhaps also as other commands suggested at http://notmuchmail.org/emacstips/#address_completion.

emacs: make headings outline-minor-mode compatible `outline-minor-mode' treats comments that begin with three or more semicolons as headings. That makes it very convenient to navigate code and to show/hide parts of a file. Elips libraries typically have four top-level sections, e.g.: ;;; notmuch.el --- run notmuch within emacs... ;;; Commentary:... ;;; Code:... ;;; notmuch.el ends here In this package many libraries lack a "Commentary:" section, which is not optimal but okay for most libraries, except major entry points. Depending on how one chooses to look at it, the "... ends here" line is not really a heading that begins a section, because it should never have a "section" body (after all it marks eof). If the file is rather short, then I left "Code:" as the only section that contains code. Otherwise I split the file into multiple sibling sections. The "Code:" section continues to contain `require' and `declare-function' forms and other such "front matter". If and only if I have split the code into multiple sections anyway, then I also added an additional section named just "_" before the `provide' form and shortly before the "...end here" line. This section could also be called "Back matter", but I feel it would be distracting to be that explicit about it. (The IMO unnecessary but unfortunately still obligatory "... ends here" line is already distracting enough as far as I am concerned.) Before this commit some libraries already uses section headings, some of them consistently. When a library already had some headings, then this commit often sticks to that style, even at the cost inconsistent styling across all libraries. A very limited number of variable and function definitions have to be moved around because they would otherwise end up in sections they do not belong into. Sections, including but not limited to their heading, can and should be further improved in the future.

Then, asynchronous harvesting over the full database is triggered. This operation may take long time (minutes on rotating disk). After it finishes, no harvesting is normally performed again and subsequent completion requests use the harvested data cached in memory. Completion cache is updated after 24 hours. Note that this commit restores (different) completion functionality for users when the user used external command named "notmuch-addresses", i.e. the old default. The result will be that the user will use the new mechanism instead of this command. I believe that many users may not even recognize this because the new mechanism works the same as http://commonmeasure.org/~jkr/git/notmuch_addresses.git and perhaps also as other commands suggested at http://notmuchmail.org/emacstips/#address_completion.

emacs: make headings outline-minor-mode compatible `outline-minor-mode' treats comments that begin with three or more semicolons as headings. That makes it very convenient to navigate code and to show/hide parts of a file. Elips libraries typically have four top-level sections, e.g.: ;;; notmuch.el --- run notmuch within emacs... ;;; Commentary:... ;;; Code:... ;;; notmuch.el ends here In this package many libraries lack a "Commentary:" section, which is not optimal but okay for most libraries, except major entry points. Depending on how one chooses to look at it, the "... ends here" line is not really a heading that begins a section, because it should never have a "section" body (after all it marks eof). If the file is rather short, then I left "Code:" as the only section that contains code. Otherwise I split the file into multiple sibling sections. The "Code:" section continues to contain `require' and `declare-function' forms and other such "front matter". If and only if I have split the code into multiple sections anyway, then I also added an additional section named just "_" before the `provide' form and shortly before the "...end here" line. This section could also be called "Back matter", but I feel it would be distracting to be that explicit about it. (The IMO unnecessary but unfortunately still obligatory "... ends here" line is already distracting enough as far as I am concerned.) Before this commit some libraries already uses section headings, some of them consistently. When a library already had some headings, then this commit often sticks to that style, even at the cost inconsistent styling across all libraries. A very limited number of variable and function definitions have to be moved around because they would otherwise end up in sections they do not belong into. Sections, including but not limited to their heading, can and should be further improved in the future.

Emacs: Add address completion mechanism implemented in elisp Currently, notmuch has an address completion mechanism that requires external command to provide completion candidates. This commit adds a completion mechanism inspired by https://github.com/tjim/nevermore, which is implemented in Emacs lisp only. The preexisting address completion mechanism, activated by pressing TAB on To/Cc lines, is extended to use the new mechanism when notmuch-address-command to 'internal, which is the new default. The core of the new mechanism is the function notmuch-address-harvest, which collects the completion candidates from the notmuch database and stores them in notmuch-address-completions variable. The address harvesting can run either synchronously (same as with the previous mechanism) or asynchronously. When the user presses TAB for the first time, synchronous harvesting limited to user entered text is performed. If the entered text is reasonably long, this operation is relatively fast. Then, asynchronous harvesting over the full database is triggered. This operation may take long time (minutes on rotating disk). After it finishes, no harvesting is normally performed again and subsequent completion requests use the harvested data cached in memory. Completion cache is updated after 24 hours. Note that this commit restores (different) completion functionality for users when the user used external command named "notmuch-addresses", i.e. the old default. The result will be that the user will use the new mechanism instead of this command. I believe that many users may not even recognize this because the new mechanism works the same as http://commonmeasure.org/~jkr/git/notmuch_addresses.git and perhaps also as other commands suggested at http://notmuchmail.org/emacstips/#address_completion.

emacs: make headings outline-minor-mode compatible `outline-minor-mode' treats comments that begin with three or more semicolons as headings. That makes it very convenient to navigate code and to show/hide parts of a file. Elips libraries typically have four top-level sections, e.g.: ;;; notmuch.el --- run notmuch within emacs... ;;; Commentary:... ;;; Code:... ;;; notmuch.el ends here In this package many libraries lack a "Commentary:" section, which is not optimal but okay for most libraries, except major entry points. Depending on how one chooses to look at it, the "... ends here" line is not really a heading that begins a section, because it should never have a "section" body (after all it marks eof). If the file is rather short, then I left "Code:" as the only section that contains code. Otherwise I split the file into multiple sibling sections. The "Code:" section continues to contain `require' and `declare-function' forms and other such "front matter". If and only if I have split the code into multiple sections anyway, then I also added an additional section named just "_" before the `provide' form and shortly before the "...end here" line. This section could also be called "Back matter", but I feel it would be distracting to be that explicit about it. (The IMO unnecessary but unfortunately still obligatory "... ends here" line is already distracting enough as far as I am concerned.) Before this commit some libraries already uses section headings, some of them consistently. When a library already had some headings, then this commit often sticks to that style, even at the cost inconsistent styling across all libraries. A very limited number of variable and function definitions have to be moved around because they would otherwise end up in sections they do not belong into. Sections, including but not limited to their heading, can and should be further improved in the future.
