A small query language atop the excellent JSONSelect for Riak Map phases.
var db = require('riak-js').getClient(); db .add('users') .map('query', ':root where .admin && !.email:val("firstname.lastname@example.org")') .run()
riak-ql.js to your
js_source_dir. This will make
query available in the global scope.
It is basically composed by a main selector, and an array of selectors exclusively used for conditions.
The main selector (the value you want to get out) is separated from the condition selectors by a
! can be used as expected. There is no
|| as JSONSelect already allows this by separating expressions with a comma (
,) - use that.
Everything is optional, which means that even an empty query will also work, returning
.email .email where !.expired :root where .name("Justin"), .name("Mark") where .admin :root where .admin && .email:val("email@example.com") && !.expired
It is a very quick hack, not a proper parser.
&& literals for other than the intended use will cause trouble.
Not recommended for production use.
