Match json object with query like elasticsearch/lucene query.
examples (jrep)
# cat a.txt
{ "foo": "bar", "bar": "foo" }
# jrep "foo:bar" /tmp/a.txt
{ "foo": "bar", "bar": "foo" }
examples (json_matcher)
>>> import json_matcher
>>> matcher = json_matcher.compile('foo:bar bar:foo')
>>> j = dict(foo='bar', bar='foo')
>>> m = matcher.match(j)
>>> m.groups()
[('foo', 'bar'), ('bar', 'foo')]
>>> matcher = json_matcher.compile('foo:>10 bar:foo')
>>> j = dict(foo=11, bar='foo')
>>> matcher.match(j).groups()
[('foo', 11), ('bar', 'foo')]
>>> j = dict(foo=9, bar='foo')
>>> matcher.match(j)
>>> m = matcher.match(j)
>>> print(m)
None
>>> json_matcher.match('foo:[10 TO 20] AND bar:foo', dict(foo=11, bar='foo')).groups()
[('foo', 11), ('bar', 'foo')]
>>> nested = dict(A=dict(B=dict(C='Hello World')))
>>> json_matcher.match('A.B.C:"Hello World"', nested).groups()
[('A.B.C', 'Hello World')]
- match text or number with
field_name:value
- match regular expression with
field_name:/regular expression/
- match range with
field_name:[10 TO 20]
,field_name:[10 TO 20}
(exclusive 20) - match range(open range) with
field_name:>20
(like elasticsearch not lucene) - match field existence with
_exists_:field_name
- match expression with
_expression:"python expression"
TODO:
- multiple match with high performace (with Ahocorasik and RE2???)
