About

What's this?

This library contains some utility functions I have been developing over the last decade or so (some even longer) and that I use extensively in almost anything I write/maintain these days.

What's so special about that?

There might not be anything really special about this, but maybe you think some of this is useful in your daily .NET developing life? These include things like:

An interface plus some utility code for optionally supplying basic progress messages to callers/UI.
Formatting of values/messages for the purpose of showing information to (UIs used by) human users.
Parsing/unparsing string values to/from strongly typed values.
Some utility extension methods on sequences/collections.
Abstract base and concrete sub classes for working with sets and ranges.
Some math and calculation related code.

Who created this?

My name is Jarno Peschier. I started programming on a Commodore 64 in high school, got a masters degree in Computer Science at Utrecht University at the end of the last century, specializing in GIS algorithms, and I have been developing software all my professional life.

You might also know me by my online name of peSHIr, which is basically the way you write my last name phonetically in Klingon.

At the start of 2025 I worked as a software engineer at Dutch engineering firm Iv, where I personally handled all software development around our scan vehicle (YouTube) using multiple third party software packages, C#, and PowerShell.

The laserscan and photo data Iv collects using this vehicle is used in infrastructure projects all over the Netherlands, but also for monitoring things like trees or quay walls in Amsterdam.

How do I use it?

Currently I am in the process of setting up the package, so really at the moment you can not do very much more than flatten a sequence of sequences into a flat sequence like this

using peSHIr.Collections;
//...
IEnumerable<List<int>> values = [[1, 2, 3, 4, 5], [99], [2024,2025]];
IEnumerable<int>? flat = values.Flatten();

Don't worry, winter... ehh... more useful code... is coming, including the code from a blog post of mine from 2011. 😉

There is more there already now, but it's not fleshed out or documented all yet. That should (also) be coming.

Version	Downloads	Last Updated
1.0.0	63	8/1/2025

Removed compact framework targeting and changed .NET Framework from 4.7 to 4.7.2 to easily enable
     multi targeted unit testing due to xunit.runner.visualstudio 3.1.0 compatibility with 4.7.2 and
     8.0, but not compact. (Did not use compact myself, so..)

     Corrected Tuple/ValueTuple inconsistency bug in MakeBatches() that could cause CastExceptions.
     Increase the unit code count as well, and no longer have any nullable related warnings any more.

     From 0.0.33-alpha the matrix code from https://www.microsoft.com/en-us/research/people/jammc with some extra usability wrappers and all test is finally there.
     (Still not everything is all documented and unit tested properly; this is still a work in progress, mostly for internal reuse for now.)
