Ok. So I gather there is no argument that would let me control this.
Below is my MWE (ok I guess it is a WE) where the formatting breaks my code.
using JuliaFormatter
using Dash
using DashCoreComponents
using DashHtmlComponents
using DashTable
fileorig = joinpath(mktempdir(),"afile.jl")
txtorig = """html_div(style=Dict("width"=>"300px"),[dcc_dropdown(id = "input-id0", options = [Dict(("label" => "some text"), ("value" => "AA")), Dict("label" => "something else"), ("value" => "pdc")], value="AA",multi = false)])"""
open(fileorig,"w") do f
write(f,txtorig)
end
include(fileorig) #works
format_file(fileorig,YASStyle())
include(fileorig) #fails
