As you see on this picture, some technologies can be researched (yellow), some not (red).
How to get this information? http://lua-api.factorio.com/latest/LuaTechnology.html

Code: Select all

local function get_tech_color(tech)
  if tech.researched then
    return 'green'
    end
  for _,pre in pairs(tech.prerequisites) do
    if not tech.force.technologies[pre.name].researched then
      return 'red'
      end
    end
  return 'yellow'
  end

local force = game.player.force --enter your force here
local color = {}

for _,tech in pairs(force.technologies) do
  color[tech.name] = get_tech_color(tech)
  end
  
print(serpent.block(color))

I noticed this doesn't work for infinite technologies though. They don't show up on the list at all.
