Closed korenmiklos closed 2 months ago

korenmiklos commented 2 months ago

Not sure how to reproduce this bug in a minimal example.

Kezdi.jl> @generate id_type = 1 @if left(frame_id, 2) == "ft"

Kezdi.jl> @replace id_type = 2 @if left(frame_id, 2) == "fc"

ERROR: LoadError: ArgumentError: column name :left not found in the data frame

julia> @generate x = 1 @if left(t, 1) == "a"
Kezdi.jl> @generate x = 1 @if left(t, 1) == "a"
