v0.2.0

Released on 2026-04-21.

vertex docs subcommand. Browse the full Vertex language reference offline, straight from the compiler binary. Subcommands include vertex docs (the curated index), vertex docs list (every topic slug, machine-readable), vertex docs <topic> (a single reference page, with prefix and fuzzy resolution), vertex docs full / vertex docs small (the complete and compact bundles), vertex docs bnf (the formal grammar), and vertex docs search <query> (substring search across every page).
vertex check <file> subcommand. Parses, resolves imports, and type-checks a .vtx file without executing it. Exits 0 on success (warnings do not fail the command) and 1 on any parse, import, or type error. Intended as the fast feedback loop for editors and LLM agents, analogous to cargo check.
LLM-friendly doc artifacts on vertex-run.github.io: /llms.txt, /llms-full.txt, and /llms-small.txt, generated per the llmstxt.org convention. These are the same artifacts the compiler bakes into its binary, so vertex docs and the published site never disagree about what Vertex looks like.
