PR Summary

While watching some demos at PSConfAsia, it's obvious that cmdlet nouns have gotten descriptive and wordy (Azure and AWS are good examples). This experimental feature enables tab-completion of abbreviated cmdlets and functions:

i-psdf<tab>

returns: Import-PowerShellDataFile

u-akvmssdr<tab>

returns: Undo-AzKeyVaultManagedStorageSasDefinitionRemoval

Note that this only works for tab completion (interactive use), so i-psdf is still an invalid cmdlet name in scripts.

The matching is entirely based on the capital letters of the verb and noun. To test this, create test.json:

{
  "ExperimentalFeatures": [
    "PSUseAbbreviationExpansion"
  ]
}

And run:

pwsh -settingsfile ./test.json
