Json-e

===================

Bugfixes
--------

- Added support for the short-circuiting of the boolean logic operators || and &&
Separated parser and interpreter.
Parser build an abstract syntax tree.
Interpreter make tree traversal. (244)

========================

Bugfixes
--------

- Part fix for 168: Enforce all error messages match

Made sure error messages for arithmetic operations, builtins, and strings are the same.

Added error messages for array indexing. (168)
- Fixed the issue of speacial values in '$let' not evaluating.

Values like 'if-then-else' statements, '$eval', and rendered keys.
The values evaluate to an object, the values of which are evaluated.
For example, the operations below no longer return an error:

title: let with a value of $if-then-else
$let:
$if: something == 3
then: {a: 10, b: 10}
else: {a: 20, b: 10}
in:
$eval: 'a + b'

context: {'something': 3}
result: 20

-----

title: let using values from the parent context
$let:
"b": {$eval: "a + 10"}
in:
$eval: 'a + b'

context: {'a':5}
result: 20

-----

title: let with a rendered key
$let:
"first_${name}": 1
"second_${name}": 2
in:
{$eval: "first_prize + second_prize"}

context: {'name': "prize"}
result: 3 (249)
- Throw a useful error for `$then` (252)
- Do not import `assert` in non-test code, so that it can run on browsers (266)
- Differentiate path/variable from the rest of the error message (283)
- [JS] Use `json-stable-stringify-without-jsonify`, dropping use of the unlicensed `jsonify`. (299)
- Better error message when indexing string or array with non integer (318)
- Strings containing unicode are now handled correctly by str() on Python 2. (338)


Improved Documentation
----------------------

- Fix typo in CONTRIBUTING.md (contributingmd)
- Clarify 'all tests pass' instruction in PULL_REQUEST_TEMPLATE.md (pull_request_template)
- The `$fromNow` builtin is tested to properly handle a new value of `now` defined in a `$let`. (344)

========================

Features
--------

- Introduction of support of TypeScript typings. This version adds type for the jsone function.

========================

Features
--------

- Support of `index` or `key` context variable in `$map` operation.

yaml
template:
$map: [2, 4, 6]
each(x,i): {$eval: 'x + a + i'}
context: {a: 1}
result: [3, 6, 9]
---
template:
$map: {a: 1, b: 2, c: 3}
each(v,k): {'${k}x': {$eval: 'v + 1'}}
context: {}
result: {ax: 2, bx: 3, cx: 4}
(235)
- Add support for element indexes in $map (242)


Bugfixes
--------

- [BREAKING] make typeof(null) be "null", not null

This is a breaking change, as it changes an existing, documented behavior.
However, it is unlikely to affect most uses of JSON-e. (246)

========================

Bugfixes
--------

- Ensure that `$match` results are deterministic (258)

========================

Features
--------

- Add new operator `$match` which allows for a new way of flow control by evaluating boolean expressions it is given. (161)
