Overview

Surfaces the command-line attack surface of Zig programs as cli:// endpoints: zig-clap param strings, zig-cli literals, zig-args struct fields, yazap App/Arg builder calls, plus std.process argv / env reads. Line-scan, merged by URL.

ARGS_FIELD_RE = /^\s*([A-Za-z_]\w*)\s*:/

ARGS_IDX = /\bargs\s*\[\s*(\d+)\s*\]/

builtin.

ARGS_IMPORT_ALIAS_RE = /\b(?:pub\s+)?const\s+(\w+)\s*=\s*@import\s*\(\s*"args"\s*\)/

zig-args: argsParser.parseForCurrentProcess(Options, allocator, .print) / argsParser.parse(Options, &iterator, allocator, .print). The receiver MUST be the local alias bound to @import("args") (captured via ARGS_IMPORT_ALIAS_RE below) -- otherwise an unrelated .parse(...) call on some other receiver (e.g. a URI parser also exposing a parse method) could be mistaken for the CLI's option struct. The type name is resolved to its const <Name> = struct { ... }; declaration (or, for an inline anonymous struct literal, the call site itself) and every top-level field becomes a flag.

ARGS_IMPORT_RE = /@import\s*\(\s*"args"\s*\)/

CLAP_ARG = /\\\\\s*<([A-Za-z_]\w*)>/

CLAP_FLAG = /\\\\\s*(?:-[A-Za-z0-9]\s*,\s*)?--([A-Za-z0-9][\w-]*)/

zig-clap multiline param string lines (each begins with \\).

CLI_LONG = /\.long_name\s*=\s*"(-{0,2}[A-Za-z0-9][\w-]*)"/

zig-cli struct literals. (Only flags are extracted: a .name literal is ambiguous between the app name, a subcommand, and a positional-arg name, so subcommand extraction from zig-cli is a follow-up.)

GET_ENV = /\b(?:std\.process\.getEnvVarOwned\s*\(\s*[\w.]+\s*,\s*"([^"]+)"|(?:std\.)?posix\.getenv\s*\(\s*"([^"]+)")/

MARKERS = /@import\s*\(\s*"cli"\s*\)|@import\s*\(\s*"clap"\s*\)|@import\s*\(\s*"args"\s*\)|@import\s*\(\s*"yazap"\s*\)|\b(?:std\.)?process\.argsAlloc\s*\(|\bclap\.(?:parseParamsComptime|parse)\b|\bcli\.(?:Command|App|Runner)\b/

STRONG_MARKERS = /@import\s*\(\s*"cli"\s*\)|@import\s*\(\s*"clap"\s*\)|\b(?:std\.)?process\.argsAlloc\s*\(|\bclap\.(?:parseParamsComptime|parse)\b|\bcli\.(?:Command|App|Runner)\b/

The subset of MARKERS that is either library-specific API usage or a bare import that pre-dates this file's zig-args/yazap support (kept as-is: an established, non-regressed convention elsewhere in this analyzer). A file matching only via a bare @import("args") or @import("yazap") -- with no corresponding API call anywhere in the file -- is NOT proof of a CLI surface (a project can vendor an unrelated module that happens to be named "args"), so it must not seed a zero-evidence cli://<binary> root endpoint. yazap doesn't need a separate evidence constant here: its bare @import("yazap") alone never seeds an endpoint either, because YAZAP_ROOT_RE / YAZAP_SUBCMD_RE / YAZAP_ADD_ARG_RE (used later, in the same forward pass) only call fetch_endpoint when they find a genuine rootCommand/createCommand/addArg call -- so an import with no real yazap usage naturally yields zero endpoints once the root pre-seed below is gated on STRONG_MARKERS.

WEB_RE = /@import\s*\(\s*"(?:zap|jetzig|httpz|tokamak)"\s*\)/

YAZAP_ADD_ARG_RE = /(\w+)\.addArg\s*\(\s*Arg\.(positional|booleanOption|singleValueOption)\s*\(\s*"([^"]+)"/

YAZAP_ROOT_RE = /(\w+)\s*=\s*\w+\.rootCommand\s*\(\s*\)/

yazap: App.init(...), app.rootCommand(), app.createCommand("name", ...) and <receiver>.addArg(Arg.positional/booleanOption/singleValueOption(...)). Receiver variables are mapped to their command URL incrementally, in the SAME forward pass as the addArg scan (see #analyze below), so a variable reused across subcommands (e.g. a generic cmd) resolves to whichever command was assigned to it as of that line, never a whole-file map where a later reassignment retroactively overwrites an earlier addArg's receiver.

YAZAP_SUBCMD_RE = /(\w+)\s*=\s*\w+\.createCommand\s*\(\s*"([^"]+)"/
