I was using split(str,separator) and it returned SubString (I verified it with typeof) and wa using the result in later functions: function instruct_processor(db::Dict,op::String) arr=split(op," ",limit=2) print("primer arr: ") println(typeof(arr)) and suddenly it returns a vector of s…

[image] martin_sanchez: I was using split(str,separator) and it returned SubString For example? (Give minimal reproducer.)

It’s hard to follow what you did and what works or not for you but the docstring for split says Split str into an array of substrings so focus on showing how to reproduce I was using split(str,separator) and it returned SubString and we can tell you whether there is some misunderstanding or …

A substring is like a view into a string, i.e., references into an existing string instead of allocating a new data structure. Many functions for splitting, matching etc on strings return substrings. Here is an example: julia> txt = "Hi there" "Hi there" julia> sub = match(r"Hi", txt).match "Hi" …

I don’t see anything surprising there. arr=split(op," ",limit=2) gives you arr as a Vector{SubString{String}}. Then arr[2] extracts one element from the vector which gives you a SubString{String}. When you send that single element to insertField! it complains because it requires a whole vector,…

The error says that insertField! expected a vector in its second argument (as per your type signature Vector{SubString{String}}), but was called with a SubString{String}, i.e., as single element of such a vector. Have not checked if this function actually needs to get passed a vector – but as split …
