Dear Julian colleagues,
I am reading the options of my model from TOML file into Structure. With the following steps:
- The TOML writes into a Dict:
- Than I am writing a code to parse Dict into Structure
The code works. But the question is how can I remove the if iKey == “evapotranspiration” and elseif iKey == “soil”.
Putting the question in another way is how do I transform a String into Struct. I was not successful in using eval methods.
Many thanks for helping to automatize the process 
Joseph
