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:
| 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 - then, 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
