The parameter expansion for regex and wildcard modifiers has to be done a bit differently, because their arguments are not s-expressions defining complete Xapian queries. [1]: id:87o7yxqxy6.fsf@code.pm lib/sexp: allow * as alias for "" in range searches. 2022-06-25T22:49:55Z David Bremner david@tethera.net 2022-06-04T21:53:58Z urn:sha1:e7ffb7404163ebb453c96f6af9724e0fba75abb0 It can be tedious to use "" inside of a string, e.g. in a shell script. lib/sexp: special case "" as an argument in lastmod ranges. 2022-06-25T22:49:55Z David Bremner david@tethera.net 2022-06-04T21:53:57Z urn:sha1:78632345868b5e4753ad402c806c29569946ce89 Support this syntax for constincy with (data from to) ranges. lib: strip trailing '/' from pathnames (sexp queries). 2022-01-27T11:48:27Z David Bremner david@tethera.net 2022-01-21T23:38:53Z urn:sha1:2c1d1107f5dacdb4a2c514909fd96f45f83e2f3c This changes makes the sexp query parser consistent with the infix one in ignoring trailing '/'. Here we do a bit better and ignore any number of trailing '/'. lib/parse-sexp: handle lastmod queries. 2022-01-26T11:41:02Z David Bremner david@tethera.net 2022-01-20T13:36:05Z urn:sha1:0a32741fceb7778ced34064eacb7b5aac2c71638 This particular choice of converting strings to integers requires C++11. lib/parse-sexp: support actual date queries. 2022-01-26T11:41:02Z David Bremner david@tethera.net 2022-01-20T13:36:03Z urn:sha1:77ab961a1dce3a31d1f0edf5c9bd83c295575835 The default argument processing overlaps somewhat with what is already done in _notmuch_date_strings_to_query, but we can give more specific error messages for the s-expression context. The extra generality of _sexp_parse_range will be useful when we implement additional range prefixes (at least 'lastmod' is needed). lib/parse-sexp: support zero argument date queries 2022-01-26T11:41:02Z David Bremner david@tethera.net 2022-01-20T13:36:01Z urn:sha1:303f207a54325158105aba400702637e670decda These are not too practical, although they may simplify some user query generation code. Mainly this adds a new prefix keyword to the parser. lib/parse-sexp: apply macros 2021-09-05T00:07:19Z David Bremner david@tethera.net 2021-08-24T15:17:41Z urn:sha1:551254eb76c9bb558078f04f21df1f6089cb03d6 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).

The code we could potentially factor out amounts to calling notmuch_database_get_config; both the key construction and the parsing of the results are specific to the query syntax involved.
