[notmuch] [PATCH] Allow saved queries for searching.
Jesse Rosenthal
jrosenthal at jhu.edu
Tue Mar 23 12:48:22 PDT 2010
Add a "query:foo" term to the notmuch search syntax. Queries are "saved
searches", and are written in the config file:
[queries]
foo=from:jrosenthal and to:notmuchmail and queries
bar=tag:personal or (tag:unread and from:whomever)
Then, if you search with the query
`tag:inbox or query:foo'
it will be passed along to notmuch as
`tag:inbox and (from:jrosenthal and to:notmuchmail and queries)'.
At the moment, when you ask for a query that doesn't exist it just
treats it as blank. This seems more consistent than bailing out with an
error (since no other search term will do that, short of running out of
memory). This does mean, though, that non-existent queries, entered by
themselves, will lead to a blank-search-term error. It should be pretty
simple to improve this behavior, but I wanted to get the initial
functionality out there.
Note that this changed the arguments to query_string_from_args to include
the hash-table of saved queries -- and since a lot functions call that
one, this patch affects all of them.
