Elderheim 0.40.0

elderheim 0.40.0

Status

This is the Dartmouth BASIC execution-core and profile-routing stop.

Highlights

• Native codegen for Dartmouth BASIC variables and assignments.
• Executable GOTO, IF ... THEN, and END behavior.
• Runtime storage for numeric and string variables.
• PRINT can now read string and numeric variables in the executable path.
• CLI and AST now expose explicit Dartmouth profiles including:
  • dartmouth-basic-1
  • dartmouth-basic-2
  • cardbasic
  • dartmouth-basic-4
  • reserved Dartmouth selectors such as sbasic and dartmouth-basic-ansi
• 1.0.0 scope is fixed to the local-manual-backed Dartmouth set:
  • dartmouth-basic-1
  • dartmouth-basic-2
  • cardbasic
  • dartmouth-basic-4
• Future BASIC manuals are now mapped to explicit dialect names instead of generic BASIC claims.
• Pentest follow-ups hardened codegen invariants, linker timeout behavior, private runtime temp files, required audit tooling, signed tag verification, and internal debug emit warnings.

Compatibility

0.40.0 is still not a full Dartmouth BASIC compiler. It expands the executable subset from constant PRINT output to variables and control-flow execution.

The temporary host C compiler linker path remains from 0.30.0. The final supported release goal is still one downloadable elderheim binary per OS/architecture, with no Rust, rustc, Cargo, C compiler, or external linker requirement where platform
constraints allow it.
