Overview

Lapis is a Lua/MoonScript web framework on top of OpenResty. Routes can be expressed in several styles:

• Method-specific calls — app:get("/path", handler), app:post, app:put, app:delete, app:patch, app:head, app:options.
• Generic app:match(path, handler) and the named app:match("name", "/path", handler) form, both of which dispatch on any HTTP method.
• Application-table style: ["/path"] = "handler_name" or ["/path"] = function(self) ... end.
• MoonScript class actions: "/path": => and the named form [name: "/path"]: =>.

Path parameters use :name and splats use *name, which already match noir's URL convention so they are surfaced verbatim. Lapis route patterns additionally carry Lua-pattern constraints (:id[%d], :slug[%w]) and optional groups ((/page/:page)), neither of which belong in a concrete URL — both are normalised away. Sub-apps mounted with app:include(...) carry an app.path = "/prefix" that every route inherits, so the prefix is detected per file and prepended to the routes bound on that app.

MOON_ACTION_MARKER_RE = Regex.union("=>", "respond_to")

moonscript_action?'s two OR-ed String#includes? scans, folded into one precompiled union so the boolean gate costs a single PCRE2 match instead of up to two naive substring scans.
