What I ended up implementing is a dict that can be dynamical created.
Here's the code for it but the dict member are blank initialised.
# names of parameters to be based to make_dictionary
ttype_names_final = {
"LAMBDA"
"EW"
"SIGMA1_RESULT"
"SIGMA3_RESULT"}
@eval function $(symbol(string("make_dictionary")))()
new_dict = Dict{Symbol,Any}()
println("making new dictionary")
# create new dictionary with each field empty
for sym in ttype_names_final
new_dict[symbol(sym)] = []
end
return new_dict
end
*a = make_dictionary()*
making new dictionary
*Dict{Symbol,Any} with 4 entries:*
* :EW => None[]*
* :LAMBDA => None[]*
* :SIGMA1_RESULT => None[]*
* :SIGMA3_RESULT => None[]*
