BARE_CALL_REGEX = /(?<![A-Za-z0-9_.:\\@])([A-Za-z_][A-Za-z0-9_]*)\s*(?:\(|(?=\s*(?:["'{]|\[\[)))/
COMMAND_CALL_REGEX = /(?:^\s*|[=,;]\s*|\breturn\s+)([A-Za-z_][A-Za-z0-9_]*)\s+(?=["'{A-Za-z_@\[])/
MOONSCRIPT_RESERVED = Set {"import", "export", "from", "class", "extends", "with", "using", "switch", "when", "unless", "continue"}

MoonScript-only keywords. These are NOT Lua keywords — class, import, from, with, switch, … are all legal (and common, e.g. middleclass's class("Foo")) Lua function names — so they are filtered ONLY when the source file is .moon, where import X from, class … extends …, and switch/when are statement keywords that would otherwise surface as phantom callees.

RECEIVER_CALL_REGEX = /(?<![A-Za-z0-9_@])(@?[A-Za-z_][A-Za-z0-9_]*(?:(?:\s*[.\\]\s*|:)[A-Za-z_][A-Za-z0-9_]*)+)\s*(?:\(|(?=\s+(?:["'{]|\[\[|@)))/

A receiver chain is a.b, a:b (Lua method call), or a\b (MoonScript method call). The : separator is kept space-free so a MoonScript table entry (success: Flow(...), where : is a hash separator, not method access) is not glued onto the following call — Lua's obj:method never carries surrounding whitespace, whereas a MoonScript key always does. . and \ keep optional whitespace.

SELF_CALL_REGEX = /(?<![A-Za-z0-9_])(@[A-Za-z_][A-Za-z0-9_]*)\s*(?:\(|(?=\s+(?:["'{]|\[\[|[A-Za-z_@])))/

Source
moonscript_value_region(source : String, value_start : Int32) : Tuple(String, Int32) | Nil

Extract a MoonScript class-action value: everything from value_start (just past a route header's :) through the end of the indentation block the header introduces. Unlike extract_moonscript_block_after, which assumes an inline arrow and stops at the first body line, this keeps the header line's trailing content (respond_to {, a wrapper call, an inline arrow) together with every more-indented line that follows, so respond_to blocks and wrapped handlers are captured whole. start_line is the header line, matching the offsets callers already expect for inline arrows.

Source
strip_comments(source : String) : String

Blank out comments and long-bracket ([[ ]]/[=[ ]=]) string bodies but PRESERVE short-string contents verbatim. Route analyzers need the path literals (app:get("/login", …)) intact while still suppressing -- comments and here-strings that would otherwise leak phantom routes. Newlines are kept so line-anchored scans and line numbering stay aligned.
