  • 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.

  • Uri Parser

    A Uri parser using the Cashel library [1]. This implementation is using ArraySegment 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. [1]

  • Yet 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.

  • Functional wrappers for TryParse APIs

    Exemplary convenience wrappers for some of the System..TryParse APIs, using the combined power of F#' return value deconstruction mechanism via pattern matching, active patterns and option types instead of "out/ref" parameters. Added support for newest versions of F# to determine which overload of TryParse should be used.
