notmuch/lib/parse-sexp.cc, branch 0.35 thread-based email index, search, and tagging https://git.notmuchmail.org/git/notmuch/atom?h=0.35 2022-01-27T11:48:27Z 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. lib/parse-sexp: handle saved queries 2021-09-05T00:07:19Z David Bremner david@tethera.net 2021-08-24T15:17:37Z urn:sha1:6ab2d9b1a2e62b76960df8e80ff2a45d9c6a8551 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). lib/parse-sexp: parse user headers 2021-09-05T00:07:19Z David Bremner david@tethera.net 2021-08-24T15:17:35Z urn:sha1:a07ef8abf5248c1128ddc75b8139ae807a88abd9 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. lib/parse-sexp: support infix subqueries 2021-09-05T00:07:19Z David Bremner david@tethera.net 2021-08-24T15:17:34Z urn:sha1:cc5992a30470222791c24849da04a3c0403ecce5 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.
