#calculator_function_names ⇒ Object

Derived at runtime, never hardcoded. docs/core-gem-contract.md §5 is explicit about why: a host app may register its own functions into the same registry, so a list copied into JavaScript goes stale the moment somebody does. The autocomplete and the "unknown function" colouring both read this.

Dentaku::AST::Function.registry holds the builtins (57 of them); the gem's own FunctionRegistry.default holds bracket, progressive_bracket, round_currency and prorate plus anything the host added. Names come back in mixed shapes across the two, so they are folded to strings and uniqued case-insensitively — matching Dentaku's own case-insensitive resolution.

end

#export_link_options(extra = {}) ⇒ Object

Turbo must not touch a file response: it has no way to render one, and swallowing the navigation leaves the operator on the page with nothing downloaded.

def export_link_options(extra = {})
  { data: { turbo: false } }.deep_merge(extra)
end

#field_class(extra = nil) ⇒ Object

Shared input chrome, so a field looks the same on every form without each view restating a dozen utility classes.
