I've found a specific case where a call to get_train_stop_trains() will cause a crash with specific conditions from a mod.

Unfortunately, seems to be nil.

Currently in on_mod_item_opened, the event handler only exposes which item prototype got the click, but there isn't any way to determine which individual item in the inventory the player clicked on.

Would it be possible to include the LuaItemStack that was right-clicked to trigger the event in ...

That's going to be a really useful improvement over how I'm doing some of the "make new copy from template train" process now, but I'm not sure if it's going to help for this specific case of keeping the new train car facing the same way relative to the rest of the train (as the template might be on ...

When looking at all the carriages on a LuaTrain, you can tell which of the locomotive carriages are facing backward or forward by checking which .locomotives array they're present in, but for the remaining carriages the best way I can find to determine their current facing is to compare .orientation ...

When looking at a rail entity, as far as I can tell the best way to get the state of the train block is to find a signal entity with find_entities_filtered to check its
defines.signal_state. I have a new mod https://mods.factorio.com/mod/train-scaling that builds trains on demand, and it'd be great ...

I have a case where it would be useful to know which direction an entity was rotated in (clockwise or counterclockwise). Would it be relatively simple to add a new parameter to on_player_rotated_entity to indicate either the entity's .direction previous to the successful rotation, or the direction ...

This would be handy - I'd like to add that it might be nice to be able to send a filter with individual (items/recipes/etc) in addition to setting types as filters.

I did a quick fix for the bulldozer mod for 0.16, for those interested: viewtopic.php?f=190&t=16151&p=362994#p362994

A minor addendum to the advantages of locals: in addition to avoiding the potential for other mods stepping on your variables, there's some slight performance advantages to local variables.

A handy way to check for where all you're using globals in a file with the luac executable.

The minimap color option is a great idea, thanks a lot for adding that!

After giving mrvn's use case/expected behavior some thought, I think I have one more improvement for belt-snapping mode, if you're up for another tweak. I think it makes it a little more consistent feeling - this way, both belt ...

Last I checked the logic is that the items flow in the direction the belt is running. In your gif you rotate the loader by 180° and then place it with the belt flowing into the stacker. Simply skip the rotating and it should work right already with less key presses. Loaders could use a mini ...

Looks great - thanks again!

After I gave it a little more thought, it might be nice to keep two separate options (belt snapping and inventory snapping, with both "ends" of inventory snapping collapsed into the same option so there aren't three?), which would allow for the flow of "build everything in order and it's all facing ...

I'd like to have this ability as well, and I don't believe that it's possible currently. Might want to move this to the modding interface requests forum?

I'm adding shanemadden's belt-facing snapping to Compact Loaders (see several posts back). But I'm not keen on adding a third config option for snapping, it's over-complex and I can't think of a good reason for that much fine control. I'm currently minded to have just a single option for snapping ...

The thing that I was thinking would make snapping smoother for my use (though I'm unsure if it'd resolve Anson's issue): check for neighbor belt-type entities instead of just looking for inventory-having entities, and use the belt's orientation to determine loader mode (belt facing into the belt-end ...
