Format of the serverProperties table

[trmckay]

Hi, I am trying to set a server property equivalent to -Dmetals.bloop-port=<N> from my Lua nvim-metals config. I have two questions about this.

1. Do I need to pass this to serverProperties as a nested table, e.g.

metals_config.init_options = {
    serverProperties = {
        ["metals"] = {
            ["bloop-port"] = 8000,
        }
    },
},

or just as one key in the serverProperties table, e.g.

metals_config.init_options = {
    serverProperties = {
        ["metals.bloop-port"]  = 8000,
    },
},

2. Does the type of the value matter? I am using a number here, but I'm not sure if I should us a string instead.

Hey @trmckay serverProperties isn't nested inside of init_options, it's just inside of the config table. So it'd be like:

metals_config = {
    serverProperties = {
        "-Dmetals.bloop-port=8000",
    },
},

Also, this setting is sort of hidden primarily because it's rarely ever used. I've actually never seen someone ask about it. What's your use case here that you want to manually set this?

Thanks! My use case is admittedly niche. I share a machine with other Metals users, so I need to make sure to pick a port that is not in use.
