Crystal recompiles an interpolated regex literal on every evaluation (a full PCRE2 JIT compile) — precompile the fixed per-verb matchers once at load time instead of per chain.

MODIFIERS = "(?:(?:private|protected|implicit|lazy|final|override)\\s+)*"
PARAM_CONST_RE = Regex.new("^\\s*#{MODIFIERS}val\\s+(\\w+)\\s*=\\s*((?:query|queries|header|cookie|path)\\[#{TYPE_PATTERN}\\]\\s*\\(\\s*\"[^\"]+\"\\s*\\)|header\\s*\\(\\s*\"[^\"]+\"\\s*\\))")

val limitParameter = query[Option[Int]]("limit")... — a reusable input combinator bound to a val. Only the combinator core is captured so any trailing .description(...) is dropped.

PATH_CONST_RE = Regex.new("^\\s*#{MODIFIERS}val\\s+(\\w+)\\s*(?::\\s*String\\s*)?=\\s*(\"(?:[^\"\\\\]|\\\\.)*\"(?:\\s*/\\s*\"(?:[^\"\\\\]|\\\\.)*\")*)\\s*$")

val UserPath = "user" (optionally /-joined literals). The captured value is already in literal form, so substituting it back into a .in(...) block lets the normal path-literal scan pick up the segments.

TYPE_PATTERN = "(?:[^\\[\\]]|\\[[^\\[\\]]*\\])+"

Type token allows one level of nested brackets (e.g. Option[String], List[User]).

VAL_DEF_RE = /^\s*(?:(?:private|protected|implicit|lazy|final|override)\s+)*val\s+(\w+)\s*(?::\s*[^=]+?\s*)?=(?![=>])\s*/

Leading val NAME [: TYPE] = of a definition. Group 1 captures the name; match.end marks where the right-hand side (the actual endpoint chain) begins. =(?![=>]) avoids stopping on ==/=>.

Instance methods

analyze_file(path : String) : Array(Endpoint)
Source
tech

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.
