Ok

on further examination there is an inconsistency between

https://lua-api.factorio.com/latest/prototypes/RecipePrototype.html

and

https://lua-api.factorio.com/latest/classes/LuaRecipePrototype.html

the first has results and the second has products

which is somewhat confusing


Edit ...

im getting from prototypes.get_recipe_filtered(filters)

but the result from prototypes.recipe['burner-lab'] is the same error

Both are "[LuaRecipePrototype: burner-lab (recipe)]"

and both error with "LuaRecipePrototype doesn't contain key results"

im testing with
log(serpent.block(prototypes ...

with RecipePrototype what are the "normal" expected values?

Im unsure if this is normal or a bug but when i read the RecipePrototype for "burner-lab"

[Edit] i get LuaRecipePrototype doesn't contain key results.
and
recipe.main_product as a ItemProductPrototype ?

{
amount = 1,
name = "burner ...

its mentioned somewhere on here, i forget where, that there is a issue? with the quality setting

you have to set quality to avoid that error
e.g

local logisticfilter = {}
local signalfilter = {}

signalfilter.type = "item"
signalfilter.name = k
signalfilter.quality = "normal ...

This appears to require iterating through the LuaLogisticPoint.sections you can get from LuaControl.get_requester_point()

Im looking to create a simple combinator mod that filters circuit signals by types (item,fluid,virtual)

i have a rough outline of code that works on a LUA combinator 3 based on https://lua-api.factorio.com/latest ...

Does anyone know a simple way of filtering out circuit signals for fluids, while i could do this with individual combinators, when i have bobs and angels, i have around 200 different fluids

in a similar way is it possible to filter out virtual signals or items as a group

Train stations Signal output appears to be rounding incorrectly

have fluid wagon with each tank containing 0.5 train show content as 1.5
however a signal wire attached to train staion reads 0

i would guess train summing before rounding round(0.5+0.5+0.5) = 1.5
where as station is rounding before ...
