Three regex-powered content tools (phase G5):
- Formula group functions gsum/gcount/gavg/gmin/gmax('regex') aggregate
over every context variable whose name matches the pattern, e.g.
gsum('leaf_.*'). Adds string literals to the formula grammar and an
IFormulaContext.ResolveMatching hook; GenomeContext enumerates matching
genes, so a trait can sum/average a gene group.
- DefDatabase content patches: a { "type": "Patch", patches:[{ defType,
match (regex on defName), set:{fields} }] } file sets fields on every
matching raw def before resolution — mods patch Core in bulk.
- DefDatabase.RegisterValidator(typeKey, field, regex): load-time check
that a string field matches a pattern, throwing otherwise (naming/format
conventions).
Covered by FormulaTests (group aggregation, composition, bad calls) and
DefDatabaseTests (patch set/match/unknown-type, validator pass/reject).
