Helps.ps1 provides functions for building PowerShell XML help files from help scripts and for creating help script templates for existing objects. Help may be created for everything that supports XML help: cmdlets, providers, scripts, and functions in scripts or modules.
Help scripts are similar to the result help and they are easier to compose than XML. Scripts make a lot of things easy. One of them is building localized help.
Step 1: Helps is distributed as the NuGet package Helps. Download it by NuGet tools or directly. In the latter case save it as ".zip" and unzip. Use the package subdirectory "tools". Consider adding this directory to the path.
Step 2: Choose the command, for example My-Command cmdlet from MyModule, and make the command available, i.e. import the module. If My-Command is a script function then dot-source the script.
Import-Module MyModule
Step 3: Dot-source the script Helps.ps1. This command loads its utility functions into the current scope, the global scope if it is called from the command line:
. Helps.ps1
Step 4: Create and copy/save the template help script of My-Command, paste/open the script in an editor and fill the empty placeholders it with proper content.
New-Helps -Command My-Command
New-Helps -Command My-Command | Set-Clipboard
New-Helps -Command My-Command > MyModule.dll-Help.ps1
Step 5: Build the XML help Module.dll-Help.xml from the help script. Copy the result to the module/script directory or a culture resource subdirectory, say, en-US.
Convert-Helps MyModule.dll-Help.ps1 MyModule.dll-Help.xml
This is it. In a new PowerShell session import the command's module or dot-source the command's script and get the command help:
Import MyModule
Get-Help My-Command
Make sure Helps-Help.xml is in the same directory with Helps.ps1 or in a culture resource subdirectory (like en-US or ru-RU in the package).
For Helps.ps1. Assuming it is in the path:
help Helps.ps1
For its functions. At first dot-source the script and then call help:
. Helps.ps1
help Convert-Helps -Full
help New-Helps -Full
