Factorio Forums

Does anyone know where lua's "print" function writes to? I don't see it on screen, nor do I see it in the log file. I'm working on a mod, so "game.player.print" doesn't work yet. Is there a way to direct it to a file? That would work for me.
Thanks!

[edit] see post 4 for a workaround/answer.

I think there currently are no ways of getting any kind of text output from code that gets run from data.lua (or data-updates.lua or data-final-fixes.lua). In code ran from control.lua you can use makefile to make log file: https://forums.factorio.com/wiki/inde ... e#makefile

On linux and mac os x it prints to terminal (stdout).
On windows, I'm afraid, it prints to non-existent console and you can't capture this output.

Thanks for this!! All I have to do to fix this is make the console exist. So, in Windows, start a "cmd" window, navigate to Factorio's x64 directory, run Factorio as then my lua print output shows up in junk.log.

Flux Faraday's is the best solution, but if you just want something quick and dirty I often use error(serpent.block(something)) to make Factorio show me the value of something in an error dialog
