gno.land/r/moul/x/daily/semverdemo/v0

Live demo of the p/moul/x/daily/semver Semantic Versioning library.

Holds the realm state the pure library deliberately does not — a "submitted versions" board (an avl.Tree of version string → submitter address) — and wires it to the chain, keying each submission by unsafe.PreviousRealm().Address():

  • Submit(cur, version) — validate with semver.Parse and post a version on-chain.
  • Render("/") — overview plus a table of worked examples.
  • Render("/<a>/<b>") — parse both and show the comparison, e.g. /1.2.3/1.2.10.
  • Render("/sorted") — everyone's submissions, lowest → highest precedence.

All parsing and comparison math lives in the library; this realm is just the board, the wiring, and the gnoweb view. Render it at /r/moul/x/daily/semverdemo/v0.

Part of moul/gno-contracts — moul's versioned gno.land contracts. See the repository for the full catalog, build/test tooling, and usage.

Overview

Package semverdemo is a small on-chain demo of the semantic-versioning parser/comparator provided by the p/moul/x/daily/semver(/p/moul/x/daily/semver/v0) library.

It holds the realm state the pure library deliberately does not: a "submitted versions" board (an avl tree of version string -> submitter address) that anyone can post to with Submit, plus a gnoweb Render view that lists them in SemVer precedence order and compares arbitrary pairs. All parsing and comparison math lives in the library; this realm is just the on-chain wiring and the view.

Submit stores a valid version on-chain, tagged with the caller's address, so Render("/sorted") can list everyone's submissions in precedence order. It validates the input with semver.Parse and panics on anything malformed.
