clang: how to list supported target architectures?
...rget cpu beyond this, though it uses a sensible default for the target cpu based on the triple.
Sometimes targets "resolve" to the same thing, so to see what a target is actually treated as:

import base64
file_name_string = base64.urlsafe_b64encode(your_string)

Match everything except for specified strings
...plit(text, @"red|green|blue").Where(x => !string.IsNullOrEmpty(x)) (see demo)
vb.net - Regex.Split(text, "red|green|blue") or, to remove empty items, Regex.Split(text, "red|green|blue").Where(Function(s) Not String.IsNullOrWhitespace(s)) (see demo, or this demo where LINQ is supported)
