The "@keys" and "@values" modifiers converts an object into an
array of its keys or values respectively.
Take this json for example:
{"first":"Tom","last":"Smith"}
@keys -> ["first","last"]
@values -> ["Tom","Smith"]
This feature was requested in #161.
This commit adds the uses the MatchLimit function, which it the
same as Match but will limit the complexity of the input pattern.
This is to avoid long running matches, specifically to avoid ReDos
attacks from arbritary inputs.
This commit adds the new tilde '~' operator, which when used will
convert a value to a boolean before comparison.
For example, using the following JSON:
{
"vals": [
{ "a": 1, "b": true },
{ "a": 2, "b": true },
{ "a": 3, "b": false },
{ "a": 4, "b": "0" },
{ "a": 5, "b": 0 },
{ "a": 6, "b": "1" },
{ "a": 7, "b": 1 }
{ "a": 8, "b": "true" },
{ "a": 9, "b": false }
{ "a": 10, "b": null }
{ "a": 11 }
]
}
You can now query for all true(ish) values:
vals.#(b==~true)#
Which returns:
[1,2,6,7,8]
Or all false(ish) values:
vals.#(b==~false)#
Which returns:
[3,4,5,9,10,11]
The last value which was non-existent is treated as "false"
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 removes the reflect package to avoid using the
reflect.SliceHeader and reflect.StringHeader structures. Instead
new sliceHeader and stringHeader stuctures have been added with
the same layout expect that they intentionally expose the data
field as an unsafe.Pointer instead of a uintptr.
