Results do not match other implementations

[cburgmer]

The following queries provide results that do not match those of other implementations of JSONPath
(compare https://cburgmer.github.io/json-path-comparison/):

• $[:2]
  Input:

  ["first", "second", "third", "forth", "fifth"]
  

  Expected output:

  ["first", "second"]
  

  Actual output:

  ["first", "second", "third"]
  

• $[1:3]
  Input:

  ["first", "second", "third", "forth", "fifth"]
  

  Expected output:

  ["second", "third"]
  

  Actual output:

  ["second", "third", "forth"]
  

• $[0:3:1]
  Input:

  ["first", "second", "third", "forth", "fifth"]
  

  Expected output:

  ["first", "second", "third"]
  

  Actual output:

  ["first", "second", "third", "forth"]
  

• $[0:4:2]
  Input:

  ["first", "second", "third", "forth", "fifth"]
  

  Expected output:

  ["first", "third"]
  

  Actual output:

  ["first", "third", "fifth"]
  

• $[0:1]
  Input:

  ["first", "second"]
  

  Expected output:

  ["first"]
  

  Actual output:

  ["first", "second"]
  

• $['key','another']
  Input:

  {"key": "value", "another": "entry"}
  

  Expected output:

  ["value", "entry"]
  

  Actual output:

  []
  

For reference, the output was generated by the program in https://github.com/cburgmer/json-path-comparison/tree/master/implementations/PHP_flow-jsonpath.

Hi... this is a helpful comparison. I had really misunderstood what the second argument of the slice operator does! I've checked the implementation against Python which I think is the standard implementation of this.

The only thing I'm not able to do immediately is extend/rewrite the parser to support the multiple string index implementation.

This project is now marked as abandoned and suggests using softcreatr/jsonpath as a replacement. If you think this issue is still relevant please open a new ticket under the new project.
