S 0.2.0

S 0.2.0

S 0.2.0 expands the existing S 0.1 language and compiler without breaking S 0.1 syntax compatibility.

Core language

• User-defined type declarations with fields and methods.
• Modules and use imports.
• List, Map, and Set collection support.
• Recoverable errors with try, fail, and structured Error values.
• File, path, time, and Duration runtime support.

Native interoperability

• C ABI support for Int, Num, Bool, Text, and Bytes.
• Binary-safe byte buffers through SBytesView with S-owned lifetime semantics.
• Native errors mapped to S NativeError.
• Opaque native handles with automatic deleters and resource cleanup.
• s bind baseline binding generator producing .snative metadata, C declarations, and C++ wrappers.

Validation

The release candidate was validated on Ubuntu GCC and macOS AppleClang with warnings treated as errors (-Wall -Wextra -Wpedantic -Werror).

The final validation suite includes:

• S 0.1 regression coverage.
• S 0.2 core tests.
• 11/11 CTest passing on Ubuntu and macOS.
• s check, s run, and s build smoke tests.
• Interpreter/native output parity.
• C ABI scalar, Text, and Bytes tests.
• Binary Bytes regression using non-text bytes including 0x00 and 0xFF.
• Opaque-handle automatic cleanup tests.
• Binding-generator end-to-end generation, compilation, S execution, native build, and parity validation.
