# scripts/set-version.sh — stamp a release version into every hardcoded spot.
#
# This is the single source of truth for *where* the version lives. The
# release pipeline (.gitea/workflows/release.yaml) calls it with the
# workflow-dispatch input; run it the same way to prepare a release by hand:
#
#   scripts/set-version.sh 0.4.0
#
# It rewrites:
#   1. Cargo.toml                 — [workspace.package] version
#   2. crates/nuwiki-lsp/Cargo.toml — nuwiki-core path-dep version pin
#   3. crates/nuwiki-ls/Cargo.toml  — nuwiki-lsp  path-dep version pin
#   4. plugin/nuwiki.vim          — g:nuwiki_version (the Lua client reads it too)
#   5. Cargo.lock                 — the version of our three own crates
#
# Cargo.lock is patched directly (awk) so this needs no cargo/toolchain —
# the only thing that changes for our crates is their version string.
