Set custom Arduino IDE preferences

[DRSDavidSoft]

Hi there, I'm looking into the documentation, but haven't quite figured this out yet.

Is there a way to pass some preferences to the ide? The command line would be something like --pref key=value, but I was wondering if there is a way to set such configuration in arduino.json, and have it be passed using the setPref() method call:

vscode-arduino/src/arduino/arduino.ts

Line 135 in 2a47a35

public async setPref(key, value) {

So maybe I could write config like this:

{
    "preferences": {
        "upload.tool": "avrdude_custom"
    }
}

Hi! After a bit of research, I found that the arduino.json can have build preferences added in the following format:

{
    "buildPreferences": [
        ["upload.tool", "avrdude_custom"]
    ]
}

Essentially just put any preference you want into the array as an array with the first element being the key and the second the value.

@davidcooper1 Great, going to test this right away!

Thank you for the tip!

Oh wow, thanks for pointing out.

    "port": "192.168.xx.yy",
    "buildPreferences": [
        [
            "runtime.pwd.192.168.xx.yy",
            "mySecretPassword"
        ]
    ],

This easily solves my ESP32 simple OTA upload-with-password problem showing "Authorization required: No authorization data found" (#676).
