CFG File Format
KSP uses a custom file format for various purposes such as part definitions, save files, and config files.
Low-level Format
Config file nodes contain a list of key = value pairs, and other nested config nodes. Keys and values are both strings and nested config nodes also have a key. Duplicate keys are allowed. CFG Files also support comments. In the data model, nested config nodes are generally separate from key-value pairs, and the node key typically defines the node's type.
- Key-value pairs
Keys and values are separated by an equals sign ("="). Values are read until the end of the line, EOF, or the start of a comment.
- Nodes
Config nodes start with their name, followed by an opening curly brace ("{") on its own line, their contents, and end with a closing curly brace ("}") on another separate line. The general convention is that config node keys are in all capital letters. Generally, node contents are indented by a single tab character.
- Comments
Comments start with a double forward slash ("//") and continue until the end of the line or EOF.
Basic Value Types
Although values are just strings, the config file codec in KSP contains a few utility methods for serializing common data types.
