T207
required parameter after an optional one
Severity Error
A parameter without a default follows a parameter that has one. Positional calls would then be ambiguous, so all required parameters must come first.
Reorder the parameters, or give the later parameter a default as well.
Failing example
script "Scaled delta"
data vd = subscribe(data.vd)
fn scaled(x: float, factor: float = 1.0, offset: float) -> float {
return x * factor + offset
}
pane p = pane(title: "Delta", height: 0.2)
plot d = plot.columns(title: "Delta (k)", on: p)
on vd.close {
d.plot(scaled(vd.close ?? 0.0, 0.001, 0.0))
