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.

Constants

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

CODEREF_RE = /=>\s*\\&\s*([A-Za-z_]\w*)/

PREFIX_BLOCK_RE = /^\s*prefix\s+(['"])([^'"]*)\1\s*=>\s*sub\b/

PREFIX_PROC_RE = /^\s*prefix\s+(['"])([^'"]*)\1\s*;/

PREFIX_RESET_RE = /^\s*prefix\s+(?:undef|''|""|'\/'|"\/")\s*;/

VERB_QR_RE = /^\s*(get|post|put|patch|options|del)\s+qr\s*(?:\{([^}]*)\}|\/((?:[^\/\\]|\\.)*)\/|!([^!]*)!|#([^#]*)#|\(([^)]*)\))/

Instance-side view of the same declaration. The per-file rescues live on this base class, which has no way to name the analyzer that is running inside them, so a skipped file could not be attributed to a tech. Deriving it from analyzer_for keeps the name written exactly once.
