[PATCH 1/2] completion: more complete completion for zsh.

This adds completion files for zsh that cover most of notmuch's cli.

The files in completion/zsh are formatted so that they can be found by
zsh's completion system if put $fpath. They are also registered to the
notmuch-* pattern, so they can be called externally using _dispatch.

Update installation recipe and drop debian/notmuch.examples to avoid
breakage. This means zsh completion is not installed for debian, to be
fixed in a future commit.

[PATCH 2/2] debian: update zsh completion installation

From: David Bremner <[hidden email]>

This ${prefix}/share/vendor-completion convention seems to be debian
specific, so leave the global default alone for now.

This completion only works on the first word in the email address,
because xapian search is word based.  As an example

to:look<TAB>     completes to [hidden email]
to:look@<TAB>    lists some odd things like localhost and ip6-loopback,
                 along with [hidden email]
to:look@m<TAB>   no completions

It's possible it would make sense to use regex search here (only available
with to: and from: prefixes), although I'd be cautious about the
performance impact. Untested, but the search term would then look like

            from:/$PREFIX/

In my unscientific tests,

     % notmuch address --output=address  from:/bremn/

took about 0.2s, while

     % notmuch address --output=address from:bremn\*

took 0.147s

That's not really a fair test, since your current query matches against
the body as well, and is slower

     % notmuch address --output=address bremn\*

takes about 0.5s

Re: [PATCH 1/2] completion: more complete completion for zsh.

Ah, that's a bit annoying.

What we could do is just stupidly load all addresses and work from there?  On my
machine, `notmuch address --deduplicate=address --output=address '*'` takes 0.25
seconds for a result set of 5500 addresses.

Could also put that result set in the zsh completion cache, for slightly less
live but immediate results on repeated calls. Is there a simple way to figure
out on the notmuch cli if a result we received is still fresh?

Here it's 1.9s for 30k addresses

notmuch count --lastmod

gives you the UUID (basically epoch) and lastmod count of the
database. That can be optimized by specifying a non-existent search
term, e.g. for me

% notmuch count --lastmod to:grendel

is quite a bit faster than

% notmuch count --lastmod

forgot amending the commit :)

In reply to this post by David Bremner-2
Please disregard the previous message. I forgot to amend a change that uses
a nonexistent query to speed up the call to notmuch count.

[PATCH] completion: load all addresses and cache in _email-notmuch

In reply to this post by David Bremner-2
This loads all known email addresses for completion, and caches the
result. The cache validity is based on `notmuch count --lastmod
mid:nonexistent`.

zsh completion finalized and squashed

In reply to this post by Vincent Breitmoser
I noticed notmuch reindex was missing from the commands and had a broken
completion.  This series also includes a version of _email-notmuch that simply
loads all mail addresses, and caches them based on lastmod.

I think this should be good now, unless anyone finds more bugs :)

[PATCH 1/2] completion: more complete completion for zsh.

This adds completion files for zsh that cover most of notmuch's cli.

The files in completion/zsh are formatted so that they can be found by
zsh's completion system if put $fpath. They are also registered to the
notmuch-* pattern, so they can be called externally using _dispatch.

Update installation recipe and drop debian/notmuch.examples to avoid
breakage. This means zsh completion is not installed for debian, to be
fixed in a future commit.

[PATCH 2/2] debian: update zsh completion installation

In reply to this post by Vincent Breitmoser
From: David Bremner <[hidden email]>

This ${prefix}/share/vendor-completion convention seems to be debian
specific, so leave the global default alone for now.

[PATCH] try regexp searching for completion

In reply to this post by Vincent Breitmoser
---

Can you try this alternative to caching, and see if the performance is
acceptable for you? I think it should be faster than your original
implementation (and also work better with multiple word [hidden email]
prefixes).

For me this is performs much nicer than the "read all the addresses"
version w/o caching. This makes it nicer out of the box for users
(like me, it turns out) who don't have completion caching turned on.

I haven't come up with a completely convincing case where caching
leaks information, but two potentially interesting scenarios are as
follows:

1) users of the "notmuch-remote" hack, which shims notmuch commands
via ssh to a remote host which might be more trusted than the local
one. This is not compelling for me because I guess shimming address
completion across ssh will be unusably slow.

2) In a future implementation of protected headers which actually
understands protected From, notmuch-address might grow a --decrypt
option. This is purely hypothetical at this point.
