How does this work when I want to specify the failure handling?

https://wl.widelands.org/documentation/productionsite_program/#call

"call = some_program on failure Fail"

crashes Wideland.

Have you tried on failure Fail as described in the documentation?

Typo in the first post, sorry. Yes, as described in the documentation; this is the output:

This part of the documentation is rather old (Year 2012). I guess this part of the documentation wasn't updated when changes to the code were made.

FYI: Some parts of the source code documentation does not live in the source code itself, instead it could be found in the subfolder doc/sphinx/source/, like the productionsite_program reference.

@hessenfarmer

It's the barbarians shipyard init.lua

I just a added "on failure Fail" to the call.

"call = ship"

"call = ship on failure Fail"

nothing else changed.

Try fail instead of Fail. Futhermore I am not sure whether any spaces around the = are allowed.

Thanks.
