luarocks install lapis-console 1.3.0

A modernization release. The frontend has been rewritten on CodeMirror 6, the console now runs on Lua 5.1 through 5.4, and results are much more useful: return values, tracebacks, and timings.

Breaking changes

  • run has a new signature. It now takes source code instead of a function: run(self, code, lang="moonscript"). It returns a result table { lines, queries, returns, time, error, traceback } instead of lines, queries, and returns nil, err only when the code fails to compile. Queries are now { query, duration } objects instead of strings. This only affects code calling run directly; console.make is unchanged.
  • POST requests require a CSRF token. The console page embeds a token generated by lapis.csrf, which is checked against a cookie when code is submitted. This stops other websites from submitting code to a console running on your machine. The token is signed with your app's secret.
  • Requires Lapis 1.7.0 or newer, for the cookie based lapis.csrf API.

New

  • Lua mode: choose MoonScript or Lua from the dropdown. Lua code previously passed validation but returned nothing.
  • Lua 5.1 through 5.4 and LuaJIT are supported. Code is loaded with its environment instead of using setfenv.
  • Return values are shown in the result. MoonScript returns its last expression, so User\find 1 works without print. In Lua mode, use return.
  • Errors keep their output: anything printed before an error is still shown, along with a collapsible stack traceback.
  • Timings: each result shows how long it took to run, and each query shows its duration when measure_performance is enabled.
  • History: each result shows the code that produced it; click it to load it back into the editor. Press up on the first line, or down on the last line, to browse previous runs, like a browser's developer console.
  • Dark mode, applied automatically from the system color scheme.
  • Table keys are sorted: array indexes first, then strings alphabetically.
  • Cmd+Enter / Cmd+K on macOS, a Clear log button, and runs are ignored while one is in progress.

Fixed

  • The query logger is restored when submitted code raises an error. Previously each error left another wrapper around lapis.logging.query.
  • The console no longer changes the app's shared cjson encode_max_depth setting.
  • moonscript is declared as a dependency, since the default MoonScript mode requires it.

Internal

  • The frontend is plain JavaScript and CSS bundled with esbuild, replacing CoffeeScript, SCSS, jQuery 1.9, CodeMirror 3.1, and Tup. See the README for build instructions.
  • Specs run with busted, and GitHub Actions tests Lua 5.1 through 5.4, LuaJIT, and OpenResty's LuaJIT, and checks that the committed generated files are up to date.
