A PropertyTree (the Factorio class name) is a recursive variant format that holds a key <> value pair where the key may be empty and the value may be only one of the following types:

PropertyTreeType (unsigned byte)
Value Name
0 none
1 bool
2 number
3 string
4 list
5 dictionary

The file format

1 unsigned byte representing the PropertyTreeType.

1 bool the any-type flag (currently not important outside of Factorio internals; default value is false)

Property Tree Type

None

Nothing

Bool

1 bool

Number

1 double

String

1 bool if there is no string - otherwise, if there is a string:

1 Space optimized unsigned int the size of the string

N byte the string contents

List

Identical to Dictionary

Dictionary

1 unsigned int the number of PropertyTree elements

For each element:

1 string the dictionary element name or it can be empty if loading a list

1 Property_tree
