Add support for reading queries from stdin, one per line, and writing
results to stdout, one per line.
This will bring considerable performance improvements when utilized in
Emacs notmuch-hello, especially so when running remote notmuch.
This allows specifying config file as a top level argument to notmuch,
and generally makes it possible to override config file options in
main(), without having to touch the subcommands.
If the config file does not exist, one will be created for the notmuch
main command and setup and help subcommands. Help is special in this
regard; the config is created just to avoid errors about missing
config, but it will not be saved.
This also makes notmuch config the talloc context for subcommands.
We now have a notmuch_config_is_new() function to query whether a
config was created or not. Change the notmuch_config_open() is_new
parameter into boolean create_new to determine whether the function
should create a new config if one doesn't exist. This reduces the
complexity of the API.
It has been a long-standing issue that notmuch_database_open doesn't
return any indication of why it failed. This patch changes its
prototype to return a notmuch_status_t and set an out-argument to the
database itself, like other functions that return both a status and an
object.
In the interest of atomicity, this also updates every use in the CLI
so that notmuch still compiles. Since this patch does not update the
bindings, the Python bindings test fails.
Move the option --no-exclude to the --exclude= scheme. Since there is
no way to flag messages only true and false are implemented. Note
that, for consistency with other commands, this is implemented as a
keyword option rather than a boolean option.
In all cases of notmuch count/search/show where the results returned
cannot reflect the exclude flag return just the matched not-excluded
results. If the caller wishes to have all the matched results (i.e.,
including the excluded ones) they should call with the
--no-exclude option.
The relevant cases are
count: both threads and messages
search: all cases except the summary view
show: mbox format
All other config-related functions and args include the section
title in their name, so for the sake of consistency, mirror that.
Also, the "auto"matic part is a given, so that was dropped.
This adds a "search" section to the config file and an
"auto_tag_exclusions" setting in that section. The search and count
commands pass tag tags from the configuration to the library.
previously we deleted the subcommand name from argv before passing to
the subcommand. In this version, the deletion is done in the actual
subcommands. Although this causes some duplication of code, it allows
us to be more flexible about how we parse command line arguments in
the subcommand, including possibly using off-the-shelf routines like
getopt_long that expect the name of the command in argv[0].
From both the implementation and from the documentation. This is
handled generically in the library for all search-based commands,
so count doesn't need special treatment.
If no parameters are given to notmuch-count, or just '' or '*' are
given, return the total number of messages in the database.
update notmuch count help
Getting the count of matching threads or messages is a fairly
expensive operation. Xapian provides a very efficient mechanism that
returns an approximate value, so use that for this new command.
This returns the number of matching messages, not threads, as that is
cheap to compute.
