I am writing a script to auto import pipe HGL information from EPA SWMM.
The only remaining issue I have is getting List.IndexOf to make a sub list if there is a repeating string. I.e. I need line 79 to have a sub list with line 15 and 16 included. Any ideas? I messed around with levels and lacing but could not figure it our. Thanks!
Here is the element if that helps:
Do you really need sub lists?
Maybe List.GroupByKey can work?
Enumerate the list and then group by key
Collating singletons isn’t necessarily the way to go, either process in a continuous one by one method or expect a list with one to many objects. If you only need to change a type parameter reduce your objects to unique types before processing. Here’s the shortest one I could figure
