Notice


Suggestions Suppliers are an experimental characteristic of seven.4-preview2+ and so you can be required to make use of one of many 7.4 previews for JSON Adapters to work.

Putting in JSON Adapter Suggestions Supplier

First to get the newest PowerShell preview for this to work on you’ll be able to obtain them on our GitHub launch web page right here.

The discharge is on the market from the PowerShell Gallery.

What are JSON Adapters?

A JSON adapter is a script that may parse the textual content output of a local executable and convert it to
PowerShell Object. JSON adapters will be made for
any command, it’s simply required to make use of the precise identify of the command because the prefix to the script.
The script should be named like so <identify of command>-json.ps1 to be recognized by the JSON
adapter utility. This script’s file location should even be added to your $env:PATH variable to be
discovered.

Making a JSON Adapter

For instance, say you’re on a Mac and need to use the command vm_stat like a PowerShell object. If
you add the next to a file referred to as vm_stat-json.ps1 and add the placement of this file to your
$env:PATH variable, the JSON Adapter suggestions supplier will determine it as a attainable suggestion
for vm_stat.

[CmdletBinding()]
param ( [Parameter(ValueFromPipeline=$true)][string]$inputObject )
BEGIN {
    $h = @{}
}

PROCESS {
    if ( $inputObject -match "^Mach Digital") {
        if ($inputObject -match "web page measurement of (d+) ") {
            $h['PageSize'] = [int]$matches[1]
        }
    }
    else {
        $ok,$v = $inputObject -split ":"
        $AdjustedK = ($ok -replace "[ -]","_").trim() -replace '"'
        $AdjustedV = "$v".Trim() -replace ".$"
        $h[$AdjustedK] = [int64]$AdjustedV
    }
}

END {
    [pscustomobject]$h
}

 

That is what the expertise appears like within the shell.

JC

JC or JSON Converter, is a command line utility that may convert textual content to JSON for number of command
line instruments. You could find directions on the right way to set up jc and a full record of supported instructions
on the repo of jc. It may be an excellent device to make use of to transform the outputs with out writing a JSON
Adapter your self. The JSON Adapter module helps utilizing jc as a JSON Adapter if the person has it
put in. This implies when you have the jc utility put in and use a command that’s supported by JC, the JSON
Adapter suggestions supplier will recommend utilizing JC piped to ConvertFrom-JSON.

It is very important notice that not all jc supported utilities are supported. The record of supported instructions is:

"arp", "cksum", "crontab", "date", "df", "dig", "dir", "du", "file", "finger",

"netstat", "route", "stat", "sysctl", "traceroute", "uname", "uptime", "w", "wc",
"who", "zipinfo"

Moreover, you have to to make use of the suitable parameters that jc requires to work correctly. For
instance, if you wish to use jc with uname, you have to to make use of uname -a as that’s what jc
requires to correctly convert the output to JSON.
