I’m adding four new expressions now, and one was added recently by <@258473836675072000> ( string_join ) so I thought I’d call them out here.

string_join/1 - join a list into a string, i.e string_join(["foo", "bar"]) => "foobar"

string_join/2 - join a list into a string with a joiner, i.e string_join(", ", ["foo", "bar"]) => "foo, bar"

datetime_add/3 - add an interval to a datetime, i.e datetime_add(^datetime, 1, :hour)

date_add/3 - add an interval to a date, i.e date_add(^date, 3, :day)

from_now/2 - add an interval to the current datetime, i.e from_now(3, :day) (the opposite of the ago expression)

today - The equivalent of now() but produces the current date.

Nice, these are great and will really clean some stuff up! 😄

I’m assuming string_join/2 will use ws_concat right?

dblack1:

concat_ws, or concat, depending if you provide a separator
