If I have a domain concept xxxx, I’ve used things like xxxx-as-cljcsv for a Clojure data structure that’s a fairly direct representation of CSV and xxxx-as-csv for a string version.

Sorry, that’s not answering your question about function names. 🙂

xxxx->cljcsv, I guess.

I think my problem is that I have a vector of vectors that is common across csv and xls that I'd like to just factor out and I don't know what to name that

v-of-v?

With no domain name part?

If it’s generic.

it isn't usually completely generic as there is often a transducer with a map and a juxt to pull out the fields in the order I want

xxxx-as-v-of-v? Or xxxx-as-vv?

I suppose I do have a general "take this seq of maps and turn it into a seq of vectors with column headers at the top" that I should factor out

that I just pass in a vector of the keys for the order, a map of keys to column names and then the vector of maps of the data

and then call that... something

but then I at least only need to name it once 🙂

I think the pivots where I'm going from a seq of maps to a map of key -> vector of numbers is a bit trickier to name (this is for grouped and column charts)

(If I’m following…) Maybe you could have separate concepts of xxxx, xxxx-as-vv and vv. And come up with a name for the “map of key -> vector of numbers” thing. Maybe xxxx-as-grouped-map and grouped-map.

me thinks

as I can't do /me
