Missing FQBNs for non AVR boards

[PeterWone]

Bug Report

Current behavior

Boards listed for the arduino:avr core specify FQBNs.

  {
    "ID": "arduino:avr",
    "Latest": "1.8.3",
    "Name": "Arduino AVR Boards",
    "Maintainer": "Arduino",
    "Website": "http://www.arduino.cc/",
    "Email": "packages@arduino.cc",
    "Boards": [
      {
        "name": "LilyPad Arduino USB",
        "fqbn": "arduino:avr:LilyPadUSB"
      },
      {
        "name": "Arduino Industrial 101",
        "fqbn": "arduino:avr:chiwawa"
      },

Boards listed for other cores do not provide FQBN.

  {
    "ID": "arduino:sam",
    "Latest": "1.6.12",
    "Name": "Arduino SAM Boards (32-bits ARM Cortex-M3)",
    "Maintainer": "Arduino",
    "Website": "http://www.arduino.cc/",
    "Email": "packages@arduino.cc",
    "Boards": [
      {
        "name": "Arduino Due"
      }
    ]
  },
  {
    "ID": "arduino:samd",
    "Latest": "1.8.8",
    "Name": "Arduino SAMD Boards (32-bits ARM Cortex-M0+)",
    "Maintainer": "Arduino",
    "Website": "http://www.arduino.cc/",
    "Email": "packages@arduino.cc",
    "Boards": [
      {
        "name": "Arduino MKR WiFi 1010"
      },

The FQBN is required by arduino-cli compile and other commands.

arduino-cli core search --format json

Expected behavior

All boards for which an FQBN is defined should report FQBN in the response to core search

Environment

• CLI version (output of arduino-cli version): arduino-cli Version: 0.13.0 Commit: 693a045
• OS and platform: Windows 10 build 2004

Additional context

67 boards are reported for various cores. 30 are from arduino:avr and only these report FQBN.

@PeterWone that looks odd I have tried the same and it works

{
    "ID": "arduino:sam",
    "Latest": "1.6.12",
    "Name": "Arduino SAM Boards (32-bits ARM Cortex-M3)",
    "Maintainer": "Arduino",
    "Website": "http://www.arduino.cc/",
    "Email": "packages@arduino.cc",
    "Boards": [
      {
        "name": "Arduino Due (Programming Port)",
        "fqbn": "arduino:sam:arduino_due_x_dbg"
      },
      {
        "name": "Arduino Due (Native USB Port)",
        "fqbn": "arduino:sam:arduino_due_x"
      }
    ]
  }

and

{
        "name": "Arduino MKR WiFi 1010",
        "fqbn": "arduino:samd:mkrwifi1010"
      }

[PeterWone]

I have an hypothesis that I am currently testing. This one may also turn out to be a documentation thing.

[PeterWone]

I can now reproduce consistent behaviour.

A board's FQBN is reported by core search only when the core for that board is installed.

Whether this is a bug depends on whether the documentation says it should happen. Personally I can't see the value of listing the boards without FQBNs.

@PeterWone the timing is right I just found out another bug with the core search in that it only searches within the platform's name. Thank you for filing #997 I'll close this one and move the discussion there
