Arquero shorthand #449
Description
Activity
It seems to me that the shorthand notation already works.
However, it's not optimal in the sense that:
- Plot calls
arrayifyon the table (running the iterator)—usingtable.indices()would avoid that step, but respecting an arquero table as being "arrayified" would work too; - Plot instantiates the channels in
valueofwithArray.from(data, field("fieldname"))—it could just calltable.column("field")if it was passed an arquero table.
If we want that optimization, we need a good method to detect an arquero-like table. Maybe when
typeof data.column === "function"? Then,arrayifywould pass it unchanged, andvalueofwould calldata.column()?- Plot calls
Sorry, I should have clarified; you’re right that it already works, but I want it to be faster by being equivalent to the longer one.
FWIW, Inputs.table depends
typeof data.columnNames === "function", but I think here we’d maybe want to usetypeof data.indices === "function" && typeof data.column === "function", if those are the functions we’d use to implement it:Reacted by Philippe Rivière
Currently to use Arquero, you say:
But with a little magic, we could support shorthand for Arquero, treating it like an array of objects:
Specifically:
