tidwall 0360deb6d8 Added new modifiers 
`@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.

tidwall 1ed2249f74 Added modifiers and path chaining 
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.

Josh Baker a2f35b522e Added support for JSON Lines 
Added support for JSON Lines (http://jsonlines.org) using the `..` prefix.
Which when specified, treats the multi-lined document as an array.

For example:

```
{"name": "Gilbert", "age": 61}
{"name": "Alexa", "age": 34}
{"name": "May", "age": 57}
{"name": "Deloise", "age": 44}
```

```
..#                   >> 4
..1                   >> {"name": "Alexa", "age": 34}
..3                   >> {"name": "Deloise", "age": 44}
..#.name              >> ["Gilbert","Alexa","May","Deloise"]
..#[name="May"].age   >> 57
```

Closes #60

Josh Baker 3f5adf1ba9 New gjson.Unmarshal function 
It's a drop in replacement for json.Unmarshal and you can typically see
a 3 to 4 times boost in performance without the need for external tools
or generators.

This function works almost identically to json.Unmarshal except that
it expects the json to be well-formed prior to being called. Invalid
json will not panic, but it may return back unexpected results.
Therefore the return value of this function will always be nil.

Another difference is that gjson.Unmarshal will automatically attempt
to convert JSON values to any Go type. For example, the JSON string
"100" or the JSON number 100 can be equally assigned to Go string,
int, byte, uint64, etc. This rule applies to all types.

Josh Baker 86b1b630e4 Query array for multiple matches 
It's now possible to query an array for multiple matches by adding the
'#' character immediately following the query.

For example, using the following JSON:

  {
    "friends": [
      {"first": "Dale", "last": "Murphy"},
      {"first": "Roger", "last": "Craig"},
      {"first": "Jane", "last": "Murphy"}
    ]
  }

To return the first match:

  `friends.#[last="Murphy"].first` >> "Dale"

To return all matches:

  `friends.#[last="Murphy"]#.first` >> ["Dale","Jane"]

Thanks to @chuttam for requesting this feature, closes #15.

Josh Baker 1a15b54bbb add bookmark link for GetMany 2016-11-28 19:04:18 -07:00
Josh Baker ae5d307631 Added GetMany. Query many paths at once. 
The `GetMany(json, paths...)` function can be used to get multiple
values at one time from the same json string.
This is preferrable to calling `Get(json, path)` over and over.
It's also optimized to scan over a JSON payload once.

This addresses a feature request by @FZambia, and closes #13.
