This commit fixes an issue where a multires query on an empty
array will result in a non-existent (empty string) result.
For example `Get("[]", "#(key=value)#").Raw` resulted in an
empty string. But, it should actually result in the empty
array `[]`.
This commit updates the match package to v1.0.3, which includes
a fix to an issue where a pattern with lots of repetitive stars
will increasingly slow down a Match operation.
Fixes#195
`@flatten` Flattens an array with child arrays.
[1,[2],[3,4],[5,[6,7]]] -> [1,2,3,4,5,[6,7]]
The {"deep":true} arg can be provide for deep flattening.
[1,[2],[3,4],[5,[6,7]]] -> [1,2,3,4,5,6,7]
The original json is returned when the json is not an array.
`@join` Joins multiple objects into a single object.
[{"first":"Tom"},{"last":"Smith"}] -> {"first","Tom","last":"Smith"}
The arg can be "true" to specify that duplicate keys should be preserved.
[{"first":"Tom","age":37},{"age":41}] -> {"first","Tom","age":37,"age":41}
Without preserved keys:
[{"first":"Tom","age":37},{"age":41}] -> {"first","Tom","age":41}
The original json is returned when the json is not an object.
`@valid` Ensures that the json is valid before moving on. An
empty string is returned when the json is not valid, otherwise
it returns the original json.
This modifier returns the current element as-is and can be used
to retrieve the JSON document itself. It is equivalent to the `#/` JSON Pointer.
Closes#149
It's now possible to do a query like
topology.instances.#(service_roles.#(=="one"))#.service_version
On a JSON document such as
{
"topology": {
"instances": [{
"service_version": "1.2.3",
"service_roles": ["one", "two"]
},{
"service_version": "1.2.4",
"service_roles": ["three", "four"]
},{
"service_version": "1.2.2",
"service_roles": ["one"]
}]
}
}
Resulting in
["1.2.3","1.2.2"]
It now possible to select multiple independent paths and join
their results into a single JSON document.
For example, given the following JSON
{
"info": {
"friends": [
{"first": "Dale", "last": "Murphy", "age": 44},
{"first": "Roger", "last": "Craig", "age": 68},
{"first": "Jane", "last": "Murphy", "age": 47}
]
}
}
The path `[info.friends.0.first,info.friends.1.last]` returns
["Dale","Craig"]
Or path `{info.friends.0.first,info.friends.1.last}` returns
{"first":"Dale","last":"Craig"}
You can also rename Object members such as
`{"alt1":info.friends.0.first,"alt2":info.friends.1.last}` returns
{"alt1":"Dale","alt2":"Craig"}
Finally you can combine this with any GJSON component
`info.friends.[0.first,1.age]` returns
["Dale",68]
This feature was request by @errashe in issue #113.
A modifier is a path component that performs custom processing on
the json.
Multiple paths can be "chained" together using the pipe character.
This is useful for getting results from a modified query.
See the README file for more information.
This fix makes calling String() on a JSON Number return the original value
as it was represented in the JSON document for signed and unsigned integers.
This ensures that very big (plus-53bit) integers are correctly returned.
Floating points maintain their previous behavior [-+]?[0-9]*\.?[0-9]*.
