class Analyzer::Zig::Http

Overview

Zig's standard std.http.Server has no routing DSL. Applications usually branch on request.head.target and request.head.method after receiveHead(), then call request.respond(...) or a handler function.

Defined in:

analyzer/analyzers/zig/http.cr

Whole-file detection gate, evaluated once per .zig file. String#matches? (PCRE2 JIT) is faster than the naive String#includes? char scan, and STD_IMPORT_RE folds the two-way OR into a single scan. Each matcher is equivalent to the literal substring test it replaces.

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.
