default.GoHeroe@localhost:6666> 

I expected to see possible messages:

• Filter
• SuperPower
• SuperPowers

proto here:
https://github.com/chemidy/goheroe-code-examples/blob/master/gRPC-Service-Discovery-With-Server-Reflection-in-go/proto/goheroe.proto

actual call works, though (which is COOL!):

default.GoHeroe@localhost:6666> call List
? Filter All
{
  "superPow": [
    {
      "name": "Flash power",
      "cat": "SciencePowers"
    },
    {
      "name": "Superman power",
      "cat": "CosmicBasedPowers"
    },
    {
      "name": "Spiderman power",
      "cat": "SupernaturalPowers"
    }
  ]
}

Yet to know how invoke this from command line one does not know which json to send.
Message type is "Filter" but what fields are there are not clear.

This works:

rualpe-ws:grpc-master paf$ echo '{"category": "SupernaturalPowers"}' | evans --host localhost --port 6666 -r --service GoHeroe --call List --cli
{
  "superPow": [
    {
      "name": "Spiderman power",
      "cat": "SupernaturalPowers"
    }
  ]
}
rualpe-ws:grpc-master paf$ 

But to known this "category" I had to dive into .proto file.
Dream: to have it all in dear Evans.

If this helps, using .proto file it works:

rualpe-ws:Downloads paf$ evans --host localhost --port 6666  goheroe.proto

Noticed different package name...

Noticed that even this way one does not know possible enum values (this is not vital, I'm not planning to use ENUMs much).

[neopaf]

(enums can be played with in REPL mode, all possible values are auto-suggested)

Thank you for pointed out an issue!
I fixed it at #89. Can you update Evans to 0.6.1?

[neopaf]

bliss! thanks, Ktr ;)
