How to properly print a train stop's name containing symbols

[boernsen2]

Hi everyone,

if I use a copper-plat symbol for a train stop name:

then print its name:

Code: Select all

game.print(train_stop.backer_name)

it prints the symbol plus an item description next to it:

How can I print the symbol only as it is displayed for the train stop name?

Thank you

I just found this page and I guess it has something to do with it:

I found this solution, which seems to work for what I have tested:

Code: Select all

function corrected_train_stop_name(str)
    if not string.find(str,"=")
    then
        return str
    else
        return string.gsub(string.gsub(str, "=", "/"), "%[", "[img=")
    end
end

It converts

Code: Select all

[item=copper-plate]

into

Code: Select all

[img=item/copper-plate]

The "correct" way is to use proper formating in stop names.
Here's a short code you could run from console to search and replace item and fluid icons in all train stop names on all surfaces:

Code: Select all

for _, surface in pairs(game.surfaces) do
  local stops = surface.find_entities_filtered{type="train-stop"}
  for _, stop in pairs(stops) do
    stop.backer_name = string.gsub(stop.backer_name, "item=", "img=item/")
    stop.backer_name = string.gsub(stop.backer_name, "fluid=", "img=fluid/")
  end
end
