jmespath does not work if json key has a dash in the name about jmespath.py

[Akasurde]

For posterity,

localhost.json

{
  "msg": {
    "rpc_reply": {
      "interface-information": [
        {
          "physical-interface": [
            {
              "active-alarms": [
                {
                  "interface-alarms": [
                    {
                      "ethernet-alarm-link-down": [
                        {
                          "data": null
                        }
                      ]
                    }
                  ]
                }
              ]
            },
            {
              "admin-status": [
                {
                  "attributes": {
                    "junos:format": "Enabled"
                  },
                  "data": "up"
                }
              ]
            }
          ]
        }
      ]
    }
  }
}

access hyphen key as -

from jmespath import search
import json
null = None
a = json.load(open("localhost.json", "r"))
print(search('msg.rpc_reply."interface-information"', a))

Output is

[{'physical-interface': [{'active-alarms': [{'interface-alarms': [{'ethernet-alarm-link-down': [{'data': None}]}]}]}, {'admin-status': [{'attributes': {'junos:format': 'Enabled'}, 'data': 'up'}]}]}]

I see that the issue can be worked around by enclosing the term in quotes:

>>> jmespath.search('"a-b"', d)
'b-c'

I suppose that suggests it's by design? If so, feel free to close this issue. Otherwise, please consider fixing and/or updating the documentation to cover this scenario (perhaps this is covered by the extensive grammar documentation, but I couldn't find it)

Sorry for the delayed response. Yes, this is by design. There's a quoted-string and unquoted-string in the grammar rules. Docs here, and a few examples here.
