Constant Summary

IMPORT_MARKER = "github.com/valyala/fasthttp"
IMPORT_MARKER_RE = Regex.union(IMPORT_MARKER)

One precompiled matcher instead of a String#includes? scan per .go file: includes? runs Rabin-Karp over the whole buffer and the marker is absent in the overwhelming majority of files in a polyglot repo, so every one of them pays the full scan. See Analyzer#content_matches?.

PARAM_LINE_SIGNAL_RE = Regex.union("QueryArgs", "PostArgs", "Request.Header", "FormValue", "UserValue", "PostBody", ".Request.Body(")

Cheap pre-filter for analyze_param_line, called on EVERY line of every fasthttp file (not just route lines). Union of every literal substring any of the six scans below requires to possibly match — a single precompiled Regex.union (PCRE2 JIT) pass replaces six unconditional String#scan regex attempts on lines that can't possibly contain a param accessor.
