I'm trying to write `map_csv` function, so that if you provide it a CSV file
name and a function how to convert row to Object it would return list of such
Objects.
import strformat, sugar
proc map_csv[T](
csv_file_path: string,
map: (
row: (key: string) -> string
) -> T
): seq[T] =
for i in 1..3:
result.add map(proc (key: string): string = fmt"{key} {i}")
result
proc load_companies1(): seq[string] =
map_csv("companies.csv", (row) => row("symbol"))
echo load_companies1()
Run
But I can't create multiline proc **with sugar**
proc load_companies2(): seq[string] =
map_csv("companies.csv", (row) =>
# How to specify multiline?
let v = row("symbol")
v
)
echo load_companies2()
Run
And also exprimental do **with sugar and type infer**
proc load_companies3(): seq[string] =
map_csv("companies.csv") do row
let v = row("symbol")
v
echo load_companies3()
Run
Is there a way to do that?
P.S.
Also, sugar seems to fail to infer this line `result.add map(proc (key:
string): string = fmt"{key} {i}")` \- could it be inferred?
