validate
Read-only
Validate GDScript syntax or scene file integrity in Godot projects. Catch parse errors before running scripts by providing a script file, inline source, or scene file, either singly or in batch.
Instructions
Validate GDScript syntax or scene file integrity using headless Godot. Use before attach_script or run_script to catch parse errors early. Single-target: provide exactly one of scriptPath, source, or scenePath. Batch: provide a targets array — runs all in one Godot process. Returns { valid, errors: [{ line?, message }] } for single, or { results: [{ target, valid, errors }] } for batch. Line numbers appear when Godot's stderr includes them (not always). Returns valid:false on any parse error; never throws.
