# development/test-keymaps.sh — drive development/test-keymaps.lua under
# headless Neovim and report pass/fail per buffer-local keymap.
#
# The Lua harness needs a real LSP attachment (most keymaps dispatch
# `workspace/executeCommand`), so we:
#   1. ensure `bin/nuwiki-ls` is built (release),
#   2. spin up a scratch wiki under a temp dir,
#   3. invoke `nvim --headless` with a minimal init that loads the
#      plugin + calls `setup()`, then sources the harness Lua.
#
# Exit code mirrors the harness: 0 on green, 1 on any failure.
