Parsing string expressions, the lazy way
Sometimes you'd be surprised at what functionality you can find inside the .Net framework. Apparently the DataTable object can compute string expressions. Nice for testing your own parser implementation, and/or for lazy coders like me. Note that the DataTable is created only once and reused with each function call.

Posted: 1 years ago by Arjen KopingaUri Parser
A Uri parser using the Cashel library [1]. This implementation is using ArraySegment<byte> as the underlying state, as I'm using it within a server, but it would be trivial to switch it to using a list. Also, note that I am not parsing the Uri into any specific structure, though that, too, would be trivial. For my current purposes, I just needed to validate the Uri.

Lazily split string
Splits strings lazily, instead of splitting entire string into an array like System.String.Split. Especially useful for very large strings.

Posted: 1 years ago by Daniel RobinsonYet another command-line parser
The snippet shows a parser for command-line arguments supporting value lists for single commands. Calling with the following arguments: "Arg 1" "Arg 2" -test "Case 1" "Case 2" -show -skip "tag" produces the following map: map [("", seq ["Arg 1"; "Arg 2"]); ("show", seq []); ("skip", seq ["tag"]);("test", seq ["Case 1"; "Case 2"])] which can be used to find what data have been sent along with different commands. Calling with the following: "Arg 1" "Arg 2" /test="Case 1" "Case 2" --show /skip:tag produces the same result.
