list of buildings...

I want to write a mod that slightly differently displays the recipe for creating an item. To do this, it is necessary to display information about the building in which this recipe can be made.
In Factorio Api -> LuaEntityPrototype, I found the field "crafting_categories :: the dictionary string → Boolean [R]" which returns a boolean instead of the list crafting_categories.
Can I get a list of "assembling-machine" in which i can execute the required recipe?
Sorry for my english.

Read the full description of crafting_categories:
http://lua-api.factorio.com/latest/LuaE ... categories
Factorio Lua docs wrote:crafting_categories :: dictionary string → boolean [Read-only]
The crafting categories this entity supports. Only meaningful when this is a crafting-machine or player entity type.
Note: The value in the dictionary is meaningless and exists just to allow the dictionary type for easy lookup.
The dictionary keys are the categories.

This field always returns a boolean value and not a dictionary key. How to get the key when calling this field?
Apparently I do not understand what it means "dictionary string → boolean".

It means that when you use .crafting_categories, it will return a map of "dictionary string"s to "boolean"s. So when you iterate over crafting_categories, you will want the keys, not the values.
I.e.
Code: Select all
for k,v in pairs(path_to.crafting_categories) do
print k --this prints my crafting categories!
end

Thank you so much!
Problem solved.

I see.
so it returns something like:
Code: Select all
{
crafting = true,
crafting-with-fluid = true,
chemistry = false,
...
}
That makes sense. Kinda.

No the values are meaningless. The key existing in the dictionary is what's useful. If it exists, then it supports it.

Code: Select all
for k, category in pairs(path_to.crafting_categories) do
If category then
Function ()
End
end
Why we are need to iterate category=false?

I mean, why we are need the list with booleans, but not just list of positive elements.

Because there is no set in lua - and table requires key-value pairs.
I'd be curious why they are not all true but thats developer in me

We can have only
Code: Select all
{
"crafting",
"crafting-with-fluid",
-- "chemistry", -- it was false
...
}

There are no false values, only a list of true values. It is done this way so you don't have to iterate the whole table to see if the machine supports it.
