Getting Started - VB6Interpret

Getting Started with VB6Interpret

Build the workspace and start executing VB6 code with the REPL, script runner, or project mode. The interpreter builds on vb6parse, vb6semantic, vb6runtime, and vb6core to provide source execution with VB6-compatible semantics.

Build and Run

Build

cargo build -p vb6interpret

Start REPL

cargo run -p vb6interpret

Run a script

cargo run -p vb6interpret -- run script.bas

Run a project

cargo run -p vb6interpret -- run MyProject.vbp

REPL sample

Dim x As Integer
x = 42
Print x
Print Left$("Hello World", 5)

Execution Modes

Mode	Command	Purpose
`repl`	`vb6interpret`	Interactive experimentation and quick checks
`run`	`vb6interpret run target.bas`	Execute source files or projects normally
`debug`	`vb6interpret debug target.vbp`	Step-through execution with inspection tools
`check`	`vb6interpret check target.bas`	Validate syntax and analysis readiness without running

Debugging

Use vb6interpret debug to step through code, inspect variables, and set breakpoints. The debugger uses the shared infrastructure from vb6core and vb6semantic for expression evaluation and variable inspection.

Limitations

Forms and controls execution is planned but not complete.
COM object support is not complete.
Behavioral parity for all VB6 edge cases is still in progress.

⚠️ Project status: VB6Interpret is under active development. Expect capability growth and occasional behavior changes while runtime semantics are refined.
