Hmm, needs review? Did you just build a parser ;) |

Still v rough and I haven't tested it yet. |

There's a MIT-licensed single-fs-file parser that I financed/own over here https://github.com/logibit/EmParsec/blob/master/EmParsec.fs — that you can paste into this code-base if you want. It's been through a couple of thousands of strings, so it should do the trick; it doesn't reify values to arguments though, like you're doing. |

It's comparing a Result<args list,string list> so a bit more tricky.

A future PR could do fuzzy matching of input flag names here

Yes a bit like powershell

Powershell lets you shorten switches as long as they are unambiguous. This actually may not be a good idea for back compact reasons when new switches are added.
A possibly more useful one would be to suggest the correct switch based on a distance measure. Worth considering in the future. If there are enough good ideas I may pull Args out as a single file Args utility. Personally keen on where this could go as I use these quite a lot.

Got it. I think the PowerShell folks got it wrong and they are starting to realize it. With PowerShell 6, a group in Microsoft was looking into Query Auto Completion-like features to predict what you want to type for a command. Sort of like next-gen IntelliSense for the command line. https://microsoft.github.io/prose/ Microsoft Program Synthesis using Examples SDK
Can you share how you use it a lot?
Simplest way to share would be to create a PowerShell Profile with a History logger extension so that you can record what you do in each session. Then you can really data mine your use cases.
