How to Load PowerShell Functions On-Demand? - powershell

Question

In my personal PowerShell profile that loads whenever I start PowerShell, I want to include a set of functions by calling a function.
So I want to do something like this:
function loadMyFunctions{
. \MyFunctions.ps1
}
Now, in MyFunctions.ps1 I have a function:
function bobtest{
write-host "My name is Bob Newhart."
}
I am able to load the script MyFunctions.ps1, but after that is loaded I am not able to call bobtest in the console - I get the error message The term bobtest is not recognized...
However, if I just load the script outside the function then that script is loaded and I can call bobtest normally - but that means that I can't just not load MyFunctions when the profile is loaded - I have to load MyFunctions and cannot choose.
You see, I want to load the other functions on demand and not have them available until I choose.
Is there another way to do this or can it even be done?

Answer 1

Have a look at this page, How to Create PowerShell Modules and Manifests.
This will enable you to create a module which will have all your custom functions! Then inside of your loadMyFunctions cmdlet add Import-Module NewModuleName.
This will enable you to use your cmdlets.
Hope this Helps,

Best way is to use modules. But still if you want to get in some different ways , then you can try with your approach.
See the below screenshots which I have performed.
I have a function addition which simply does addition and I saved it as funct1.ps1
Now I am calling the same function from another function of the other script just using dot source without using as module and it results me properly.
Funct1.ps1
Triggered the function from another function in another script .
Hope it helps...!!!
