Interface UseFormulaInputPartsOptions

The headless field API driving this chrome (useFormulaInput).

The call argument the field's whole text is — see UseFormulaHintsOptions.getArgument. An empty field then offers the values its parameter is limited to.

Disabled fields render plain glyphs — no overlay, no tip.

The two grammars a formula-backed field can enforce.

• 'formula' — any formula expression (=SUM(A1:A5)*2). The field text is one expression; the picker projects the expression's REFERENCES (per token) and a pick re-scopes the caret's reference or splices a new one at the caret — the formula editor's point model.
• 'reference' — a pure reference list (Sheet1!A1:B2, Sheet2!C1). The field text is comma-joined reference segments; the picker projects the SEGMENTS (segment index = picker range index) and a pick re-scopes/appends a segment. Function calls and computed expressions are invalid — the field accepts only what ICalculation.IFormula.isReferenceOnly holds for (Excel's RefEdit contract: OFFSET/INDIRECT-style computed references are not accepted; those belong in a 'formula' field, e.g. a name's refers-to).

The formula's HOME anchor ('formula' grammar) — bare references evaluate against it.

Resolution context for the 'formula'-grammar eval tip. Defaults to the enclosing WorkbookContext (the same resolution the headless core applies).
