Utilities to manipulate variants and type descriptors

ExtractClusterElementByName has inverted logic

Contribution to Variant-Object handling (reflection)

Hi,

for a recent project I created some tools to handle VObjects, including their generation, casting and reflection (adjacency etc). Do you think they would fit into this toolbox? If yes I would polish and bundle them for a pull-request.

Have a nice day!

KVP Parser should have a smarter String to Path conversion to be compatible with INI file encoding

NI's INI API, OpenG's VariantINIConfig and OpenSerializer's PlainText classes all encode the paths in a way that allows to reconstruct a relative path from a string.
The KVP Parser only uses the basic primitive and misses on this important format

The excerpt below needs to include some smarts to handle each use cases.

Add a new method to "Append Element to Cluster"

useful method to build a cluster from KVPs

Simplifications to KVP Parser are possible

• Cluster should be in two loops, not three.
• KVP lookup can be by variant attribute name directly.

Make reuse method for variant to scalar and array

Only cluster is recursive, so make the rest of the "Variant_KVP to Strict Variant.vi" be a separate public method.

Tree to Variant Conversion is missing the SetName method in building cluster

Variant to Strict Cluster should map cluster by order

KVP Parser should use dot notation for all decimal numbers

Scalar to String methods

Variant_KVP to Strict Variant.vi sometimes incorrectly converts numeric arrays

This occurs when the KVP variant type contains an array with numeric values and the numeric type does not match the corresponding default value variant type.

I've narrowed the bug down to the following case structure:
OpenVariant.lvlib:Variant_KVP to Strict Variant.vi with case structures: true -> default -> array -> true

Unfortunately, I do not understand the code well enough to come up with a fix.

I encountered this bug as part of an issue in: LabVIEW-Open-Source/Serializer#5

Support escaped characters in CSV file Read and Write

Add a new section to the DataManipulation palette (perhaps a separate package)

• Read from CSV File
• Write to CSV File

Both methods should support encoding and decoding with escaped chars.
