Custom formatting generator

[tiagovla]

What should I return if I want the whole buffer to be replaced with result? It seems like it expects a LSP edit?

require("null-ls").setup {
    sources = {
        {
            name = "custom",
            filetypes = { "python" },
            method = require("null-ls").methods.FORMATTING,
            generator = {
                fn = function(params)
                    local result = custom_format(params.content)
                    return {  } --???
                end,
            },
        },
    }
}

return { text = result }

works I guess.
