Support for any_of()

[amrods]

Is there any way to achieve functionality like tidyverse's any_of()?

My use case is that I am reading only certain columns of a file, but there could be columns specified in the call, but non-existent in the file:

vars = ["one", "two", "three"] # column two does not exist in the file
df = read_csv(file, col_select=any_of(vars))

Thank you for bringing this up.

any_of is definitely on our list of things to do, but I think the ability you are looking for already works.

col_select will only pull columns that match, and will not error if a column is provided in the list, but not in the file. Does this work for you?

file_path = "path.csv"
DataFrame(
    one = [1, 2, 3, 4, 5],
    three = [true, false, true, false, true],
    five = ["a", "b", "c", "d", "e"]
)|> x-> write_file(x, file_path)

vars = ["one", "two", "three"] # column two does not exist in the file, and five is not read as it is not in the list

read_csv(file_path, col_select=vars)
5×2 DataFrame
 Row │ one    three 
     │ Int64  Bool

   1 │     1   true
   2 │     2  false
   3 │     3   true

   5 │     5   true
