Module scripting 

Scripting integration — run FormCalc calculate/validate scripts on form fields.

Implements XFA Spec 3.3 §14.3.2 event model for calculate and validate events. Before layout, the engine executes calculate scripts on fields to compute derived values, then optionally runs validate scripts to check constraints.

NOTE: This module handles simple calculate/validate scripts with a flat interpreter. The more advanced dynamic scripting (initialize events, SOM-based field resolution, presence toggling) lives in pdf-xfa/src/dynamic.rs which uses the full FormTree SOM resolver.

Structs

ScriptResult

Result of running all scripts on a form tree.

Enums

ScriptError

Errors from script execution.

Functions

prepare_form

Run calculate scripts, then layout. Convenience wrapper for the common flow.

run_calculations

Execute all calculate scripts in the form tree, updating field values.

run_validations

Execute all validate scripts in the form tree, collecting failures.
