This is my personal PowerShell profile, containing my own extensions and extension loader. The extension loader can be found in spse-init.ps1, which is intended to be imported from your PowerShell profile script (Microsoft.PowerShell_profile.ps1). Inside of spse-init.ps1, an object called SPSEEnv is defined - this object stores the configuration for the extension loader.

The SPSEEnv object is defined like this, and should have its values modified according to where the repository is stored on your computer:

New-Variable -Name SPSEEnv -Value @{
    repositoryDirectory            = [String]"$HOME\Dropbox\Repositories\shaynas-powershell-extensions"
    repositoryExtensionsDirectory  = [String]"$HOME\Dropbox\Repositories\shaynas-powershell-extensions\extensions"
    enabledUserExtensionsDirectory = [String]"$HOME\shaynas-powershell-extensions\enabled-user-extensions\"
    loadedExtensions               = [Array]@()
}

The extension loader recognizes all .ps1 PowerShell scripts within repositoryExtensionsDirectory to be "extensions", and it will consider the extension enabled if a symlink exists within enabledUserExtensionsDirectory that points to that extension. Upon startup, all symlinks within enabledUserExtensionsDirectory that point to .ps1 files inside of repositoryExtensionsDirectory will be imported.

Extensions can be "enabled" or "disabled" using the SPSE_SetExtensionEnabled command, which will create or delete a symlink within enabledUserExtensionsDirectory for the given extension, like this:

SPSE_SetExtensionEnabled Get-Weather.ps1 -Disable

Extensions and their state can be viewed using the SPSE_GetExtensions command, where the -Pretty switch can also be specified to prettify the output.

➜ SPSE_GetExtensions -Pretty
--------------------------------------------------
[ E ] Encryption-Utilities.ps1
[ E ] Get-PublicIP.ps1
[ E ] Get-Weather.ps1
[ E ] OhMyPosh-Setup.ps1
[ D ] RegistryConsoleFontManager.ps1
[ E ] Set-TitlebarColor.ps1

When the -Pretty switch isn't used, an array of PSCustomObject's is returned, which can have the following methods called on them: .IsEnabled(), .Enable(), .Disable() to be able to query and manage the state of the extensions programmatically.

Additionally, the state of a specific extension can be queried using the SPSE_IsExtensionEnabled command.

If for whatever reason, an extension is deleted from repositoryExtensionsDirectory without being disabled first, any lingering symlinks can be cleaned up using the SPSE_RemoveZombieSymlinks command.
