v1.1.0

Changelog - Peel Programming Language

[v1.1.0] - 2026-03-30

Added

• SQLite Standard Library (sqlite):
  • Integrated rusqlite for high-performance database interactions.
  • sqlite.open(path): Opens a database connection (supports ":memory:").
  • Connection.execute(sql, params): Executes mutation statements.
  • Connection.query(sql, params): Executes queries and returns an Array of Objects.
  • Connection.close(): Manually closes connections.
• Loop Support:
  • Implemented for .. in .. loop syntax in the parser and interpreter.
  • Implemented while loop syntax for conditional iteration.
• SQLite Demo: Added examples/sqlite_demo.pel to showcase database usage.

Improved

• Type System:
  • Added support for Heterogeneous Arrays (e.g., ["Alice", 95.5, true]). The type checker now falls back to Unknown for mixed-type lists instead of erroring out.
  • Robust String Concatenation: The + operator now supports concatenating String with any other type (Int, Float, Bool, Void, etc.) by automatically stringifying the right-hand/left-hand sides.
• Standard Library Registration: Unified sqlite registration across the runtime interpreter and the type checker.

Fixed

• Fixed a parser bug where For and While keywords were present in the lexer but caused "Unexpected token" errors during parsing.
• Resolved type mismatch errors when printing mixed database results.
