class Analyzer::Perl::Dancer2

Overview

Dancer2 route DSL analyzer.

Dancer2 (https://github.com/PerlDancer/Dancer2) exposes routes through a keyword DSL exported by use Dancer2:

get '/' => sub { ... }; post '/users' => sub { ... }; del '/users/:id' => sub { ... }; # del, not delete any ['get','post'] => '/feed' => sub { ... }; any '/all' => sub { ... }; # every HTTP verb

prefix '/api' => sub { # block-scoped prefix get '/status' => sub { ... }; # => /api/status }; prefix '/v2'; # procedural prefix get '/ping' => sub { ... }; # => /v2/ping

Route paths support named placeholders (:id, with optional type constraints :id[Int]), splat (*) / megasplat (**) wildcards, and regex routes (qr{...}). Handlers read input through the modern accessors (route_parameters, query_parameters, body_parameters, cookies, request->header, upload) as well as the legacy param/params helpers.

Constant Summary

ANY_BARE_RE = /^\s*any\s+(['"])([^'"]*)\1/
ANY_LIST_RE = /^\s*any\s*\[([^\]]*)\]\s*=>\s*(['"])([^'"]*)\2/
ANY_LIST_VERBS = ["get", "head", "post", "put", "del", "delete", "patch", "options"] of ::String

Verb spellings accepted inside an any [...] method list. Dancer2 normalizes del to delete and registers HEAD alongside GET, so the arrayref form takes both the route-keyword spelling (del) and the HTTP-method spelling (delete, head).

ANY_METHODS = ["GET", "POST", "PUT", "DELETE", "PATCH", "OPTIONS", "HEAD"] of ::String
