Visible in every file, with no import. 15 module(s).

BitsThe `Bits` module provides bitwise operations on `Integer`. ConsoleANSI terminal styling. Color constants become empty strings when Kex is started with --no-colors, so callers can compose them without branching. DigestCryptographic content digests. Hex strings are used at the public boundary so Kex programs never need to handle backend-specific binary values. EvaluatorSandboxed evaluation of Kex source code at runtime. MathThe `Math` module provides standard mathematical constants and functions. All trigonometric functions operate in radians. A Kex `Float` is always finite, so a domain error (`Math.sqrt(-1.0)`) or an overflow (`Math.exp(1000.0)`) raises rather than producing `NaN` or `Infinity` — the same rule BEAM enforces, where those two values cannot exist at all. Integer Float Number ParserParses Kex source code into a structured AST at runtime. Stream TaggedValidationDiagnostics returned by optional compile-time tagged-literal validators. Byte offsets are zero-based and relative to the cooked literal body. AssertFocused assertions are ordinary Kex stdlib functions layered on the primitive `assert`, so adding another helper does not require compiler or runtime work. Web Web.Response Web.Server
