RuleLoader is the algorithm that Golly uses to simulate .rule files, also known as rule tables and rule trees. A description of the file format is provided in Golly's built-in help.[1][2]
Description
- See also: Tutorials/Creating custom rules
The RuleLoader algorithm allows rules to be specified in external files. Given the rule string "Foo", RuleLoader will search for a file called Foo.rule.[1]
A .rule file contains all the information about a rule: its name, documentation, table/tree data (used by the RuleLoader algorithm), and any color/icon information. The .rule format is textual and consists of one or more sections. Each section starts with a line of the form @XXX... where X is an uppercase letter. If there is more than one section with the same name then only the first one is used. Any unrecognized sections are silently ignored.[2]
The currently recognized sections are:[2]
- @RULE (mandatory)
- @TABLE (optional)
- @TREE (optional)
- @COLORS (optional)
- @ICONS (optional)
