Enjoying Switches in Personal Powershell

The concern is documenting my recent enjoyment of switching for personal use when I just run

shp com.acme-prod1 c

… from anywhere and this pulls the recent updates from the acme repo + immediately opens a config file I want to check

1. backstory

• I was listening to programmers saying “don’t do switching”
• But I realized this is advice starts to pay off at the certain level of complexity
• In my personal use of PowerShell, I use lots of procedures where I pass a letter of the alphabet that is suggestive of the name of the feature I want to use and it does it
• take for example this go-ToRepo function living in my $profile
• and I am using all of them and it (I believe) reads well (sorry for the cmdlet aliases)

2. CODE

# the concern is pulling recent updates from a repo + doing a required action as per the feature flag
function go-toRepo ($repoString, $featureFlag) {
    $repostring = $repoString -replace "-.*", ""
    $configFile = ".\jobs\config.yml.tmpl"
    $redShiftFile = ".\jobs\enriched_redshift.json.tmpl"
    $scheduleFolder = ".\schedules"
    $repoFolder = "C:\Users\Admin\repos\"
    if (Test-Path "$repoFolder\*$repoString*\") {
        pushd "$repoFolder\*$repoString*\"
        git pull 
        switch ($featureFlag) {
            "b" { gc $configFile | sls "buckets:" -Context 15; Break }
            "c" { ii $configFile; Break }
            "r" { ii $redshiftFile; Break }
            "s" { dir $scheduleFolder | gc; Break }
        }        
    }
    else { Write-Host "was not cloned yet" -ForegroundColor cyan }
}
# within $profile
Set-Alias shp go-toRepo
