[Loading error] Error with Eradicator's L.I.B.R.A.R.Y.

[sproott]

I'm using YAFC version 0.5.8 from FlatHub and Factorio version 1.1.76.

When loading YAFC with just Eradicator's L.I.B.R.A.R.Y., it crashes with the following error:

... the rest of the stacktrace

I tried to investigate a bit myself, but I couldn't really make much out of this, just that the mod does some interesting stuff with running require on 00-toggle-to-enable-dev-mode, which seems to be a small utility mod that you can install by copying it into your mods folder (see this subdir). Nonetheless, it works in Factorio but crashes YAFC.

Here's a save file to sync mods.

I can't figure out what Eradicator's doing either. I believe I found an issue with YAFC's handling of pcall(require, ...), but that isn't the only problem here.

Until someone smarter can figure out how to fix it properly: (1) replace the two calls to does_file_exist in shared.lua with false, and (2) on line 346 of erlib/factorio/Stacktrace.lua, replace flag.IS_FACTORIO with false. I don't know if/how this will mess up anyone using erlib, though.

ShadowTheAge: I tried making FactorioDataSource.ReadModFile return null when it intercepted pcall(require, '__00-toggle-to-enable-dev-mode__/empty'), but I couldn't figure out how to get pcall to return false.
