sean-m / PSAssert.ps1

Last active April 14, 2021 17:21

Don't use this! Use Pester. Simple functions for writing assertion tests that will throw exceptions in a composable way without any external dependencies. All test functions return $true if passed so they can be used as a predicate, they throw on failure to stop script execution. This exists to simplify testing for invariants in production scrip…


	class AssertionException : System.Exception {
	AssertionException ([string]$Message, [System.Exception]$InnerException) : base($Message,$InnerException) { }
	}

	function Assert-Contains {
	param (
	[object[]]$Collection,
	[string]$Property=$null,
	$Pattern,

sean-m / zip.ps1

Created June 22, 2020 23:43

helper for using Linq zip in powershell, short enough to write manually but easier to paste one that already behaves.

	function Zip {
	param ([object[]]$first, [object[]]$second)

	[Func[object,object,object]]$zipper = { param ($a, $b) New-Object PSObject -Property @{First=$a;Second=$b} }
	[System.Linq.Enumerable]::Zip($first, $second, $zipper)

sean-m / sshtunnel.sh

Last active May 31, 2020 20:18

Simple script for tunneling ports over ssh so I don't have to look up the ssh switches each time.

	while [[ $# -gt 0 ]]
	do
	key="$1"

sean-m / ping_log.ps1

Created April 29, 2020 17:33

One-liner for continuous ping with logging. Use it all the time and need a place to put it.

ping /t 192.168.1.1 | select -Skip 2 | % { "$(Get-Date -Format 'o'),$_" } | Tee-Object -FilePath "$env:temp\ping-$(Get-Date -UFormat %s).csv" 

sean-m / HeaderComment.ps1

Last active October 5, 2020 23:21

It gets old trying to do these by hand all the time, pipe to clip.exe and call it a day.

	## Generate comment blocks that can denote regions in your script
	filter HeaderComment {
	[Alias('HC')]
	param(
	[Parameter(Position=0, ValueFromRemainingArguments)]
	$msg
	)
	$msg = $msg -join ' '
	@"
