The mod Pressurized Barrels ( https://mods.factorio.com/mod/PressurizedBarrels ) automatically generates barreling recipes for Pressurized fluids ( https://mods.factorio.com/mod/CompressedFluids ).

These don't appear to be handled by this add-on.

Thank you for the feedback, I'm going to have a look at this as soon as I can 👍

Ok so they are using a different item subgroup than the one used by the base game ("hp-fill-barrel" instead of "fill-barrel" and "hp-empty-barrel" instead of "empty-barrel") so it wasn't affected by my script.
I updated the mod so it should work fine now.

I use the mod version 0.1.2 when I try to put a barrel filled with pressurized water in the Unbarreling Machines, in response it is written that the barrel cannot be melted https://i.imgur.com/Y5kFr9D.png

@Xaetral .. can you add an optional dependency on "PressurizedBarrels"

"dependencies": ["base >= 1.1", "? PressurizedBarrels"]

That way your mod will wait on mine to load before yours looks at changing recipes.

Ah I see what's happening there, the PB mod already uses final-fixes :/
I did the quick fix of adding an optional dependency, I've tested it out this time, thank you both ^^'

I also fixed the custom technology added by both mod as it had the huge amount of barreling recipes being displayed.
