validate_spintax
Static validation: returns diagnostics with severity, stable code, message and 1-based line/column. No "error"-severity diagnostic means the template is structurally sound — read the warnings before rendering, because some of them (plural.locale-missing) mean a block will not resolve. Pass knownVari
render_spintax
Renders up to 20 variants. With a seed the output is deterministic (variant i uses seed "<seed>#<i>"); without one it is random. The engine is lenient: structural mistakes never throw, they surface in the output — run validate_spintax first.
analyze_spintax
Reports what the template needs and contains: refs (variables referenced), sets (#set macros, re-picked per reference), defs (#def, rolled once per render), includes, diagnostics, and best-effort construct counts. Answers "what variables must I supply" — it is NOT a variant-cardinality counter.
spintax_authoring_guide
Read this BEFORE writing or editing a spintax template — it is the canonical authoring guide the whole spintax toolchain is written against, not a tutorial. Pass the locale you will author in: for ru/uk/be and sr/hr/bs it carries the agreement and case rules that decide whether the variants read as
