Macros implement lazy evaluation and lexical scope. The former is
needed to make certain natural constructs work sensibly (e.g. (tag
,param)) but the latter is mainly future-proofing in case the DSL is
is extended to allow local bindings.
For technical background, see chapters 6 and 17 of [1] (or some other
intermediate programming languages textbook).

This commit does not enable using saved s-expression queries, only
saving and retrieving them from the config file or the database. Use
in queries will be enabled in a following commit.
This provides functionality analogous to query: in the Xapian
QueryParser based parser. Perhaps counterintuitively, the saved
queries currently have to be in the original query syntax (i.e. not
s-expressions).
One subtle aspect is the replacement of _find_prefix with
_notmuch_database_prefix, which understands user headers. Otherwise
the code mainly consists of creating a fake prefix record (since the
user prefixes are not in the prefix table) and error handling.
This is necessary so that programs can take infix syntax queries from
a user and use the sexp query syntax to construct e.g. a refinement of
that query.
At least to the degree that the Xapian QueryParser based parser
also supports them. Support short alias 'rx' as it seems to make more
complex queries nicer to read.
The many tests potentially overkill, but they could catch typos in the
prefixes table. As a simplifying assumption, for now we assume a
single argument to the wildcard operator, as this matches the Xapian
semantics. The name 'starts-with' is chosen to emphasize the supported
case of wildcards in currrent (1.4.x) Xapian.
We use "boolean" to describe fields that should generate terms
literally without stemming or phrase splitting. This terminology
might not be ideal but it is already enshrined in
notmuch-search-terms(7).
Anything that is quoted or not purely word characters is considered a
phrase. Phrases are not stemmed, because the stems do not have
positional information in the database. It is less efficient to scan
the term twice, but it avoids a second pass to add prefixes, so maybe
it balances out. In any case, it seems unlikely query parsing is very
often a bottleneck.
All operations and (Xapian) fields will eventually have an entry in
the prefixes table. The flags field is just a placeholder for now, but
will eventually distinguish between various kinds of prefixes.
There is not much of a parser here yet, but it already does some
useful error reporting. Most functionality sketched in the
documentation is not implemented yet; detailed documentation will
follow with the implementation.
This new command for notmuch-tree-mode is analogous to
notmuch-search-filter-by-tag, bound to "t" in notmuch-search-mode; it
gets therefore the same "t" keybinding in notmuch-tree-mode (replacing
the current assignment to notmuch-search-by-tag).
New --sort CLI option documented in notmuch-show's man page, and
notmuch-search-toggle-order mentioned in doc/notmuch-emacs.rst and
devel/emacs-keybindings.org (in the latter, there's also some
whitespace changes in a table introduced by org-mode).
After some discussion [1], I decided it is better to make notmuch users
who rely on this behaviour customize mail-user-agent. This is
consistent with the behaviour of other emacs mail packages.

Example reference to a command-line option using the option role
reference. This creates a hyperlink in html, and the usual boldface
style in man page. This could be used throughout the man pages.
Use the program and option directives to document the subcommand
options. This unifies a lot of option documentation throughout.
This also makes it possible to reference options with :option:`--foo`
(within .. program::) or :option:`subcommand --foo` (globally). This
is left for later work.
See https://www.sphinx-doc.org/en/master/usage/restructuredtext/domains.html#directive-program
Note: There is a lot of indentation change, but intentionally there is
no reflow. Using 'git diff -w' or 'git show -w' to ignore white space
changes makes this a very easy change to review.
Make man1/notmuch.rst the single point of truth for describing notmuch
environment variables. Use the envvar directive for that, and
reference them with the envvar role.
Drive-by cleanup configuration file and hook directory search order
documentation.
Add internal hyperlink targets for man pages and cross-reference them
using the any role reference. There are a number of alternatives to
accomplish this, but this seems like the combination that retains the
man page section number and the same boldface style in the man pages.
As a bonus, we get sanity checking on the links; for example
notmuch-search-terms.rst had a reference to notmuch-properties(1)
i.e. the wrong section.
The obvious semantic follow-up change would be to only have meaningful
"see also" references instead of having them all everywhere.
Using manpage role references generates helpful links in html
documentation, while retaining the same boldface style in the man
pages.
The external man page site is configurable. The Debian manpage site
seems like a good fit for Notmuch.
Variable 'notmuch-saved-searches-sort-function' does not exist;
'notmuch-saved-search-sort-function' is the correct name.

Sphinx 4.0 changed the default value of man_make_section_directory
from False to True. We create the section directories and move the
files manually, so fix the immediate man build failure by disabling
the feature.
The Sphinx documentation on this [1] is confusing, and has the change
backwards. Git history says the default changed from False to True.

Previously the fact that some configuration options were only stored
in the database (and thus editing the config file had no effect) was a
source of user confusion. This was fixed with the series ending at
d9af0af164.
On the other hand, the underlying partition of config options into
those stored by default in the database and those stored in the config
file remained. This is also confusing, since now some invocations of
"notmuch config set" modify the config file, and others silently
modify the database instead.
With this commit, it is up to the user to decide which configuration
to modify. A new "--database" option is provided for notmuch config to
enable modifying the configuration information in the database;
otherwise the default is to update an external config file.
Introduce a new configuration value for the mail root, and use it to
locate mail messages in preference to the database.path (which
previously implied the mail messages were also in this location.
Initially only a subset of the CLI is tested in a split
configuration. Further changes will be needed for the remainder of the
CLI to work in split configurations.
Remove STORED IN DATABASE discussion, describe search rules.
Currently profiles seem a bit pointless. They will make more sense
when they apply to databases as well.
Under a sufficiently high level of parallelism [1] there seems to be a
a race condition that allows sphinx-build to start running before the
docstrings are extracted. This change moves the docstring stamp from
the phony targets sphinx-html and sphinx-info to the file targets that
they depend on. I'm not sure why this makes things better, but I am
fairly confident it does not make things worse, and experimentally it
seems to eliminate the race condition.

Building Notmuch on macOS is known to cause problems because the Notmuch
distribution archive contains two files named "version". These names
clash with the <version> header as defined in C++20. Therefore, the
existing naming will likely become a problem on other platforms as well,
once compilers adopt the new standard.

Amended-by: db s/keyword/header/ in commit message.
Use `makefile-gmake-mode' instead of `makefile-mode' because the
former also highlights ifdef et al. while the latter does not.
"./Makefile.global" and one "Makefile.local" failed to specify any
major mode at all but doing so is necessary because Emacs does not
automatically figure out that these are Makefiles (of any flavor).
It is getting unwieldy to pass configuration options on the
sphinx-build command line, and I anticipate further use of
conditionals.
As far as I could tell, execing a string is the idiomatic way to
emulate include in Python.
gzip includes the name of the uncompressed file and its modification
timestamp into the compressed archive. The latter makes it hard to
reproduce the generated files bit for bit at a later time, so omit this
information from the archive using the "--no-name" option. This is a
reproducibility best practice, see
https://wiki.debian.org/ReproducibleBuilds/TimestampsInGzipHeaders
The features that require field processor support, are now just
documented w/o mentioning **Xapian Field Processors**' is needed
for those.
Replaced "compact" and "field_processor" with "retry_lock" in
build_with config option, as it is currently the only one that
is optionally excluded. The former 2 are now documented as
features always included.
Dropped one 'we' "passive" in notmuch-search-terms.rst. It was the
only one, and inconsistent with rest of the documentation in that
file.
Dropped message about conditional open-ended ranges support, as
those are now always supported.
