`In` in `SignIn` is truncated from command names

[peombwa]

Given an operationId of reports_ListApplicationSignInDetailedSummary, AutoREST.PowerShell currently generates a command name of Get-ReportApplicationSign instead of Get-ReportApplicationSignInDetailedSummary. It looks like AutoREST.PowerShell treats the In in SignIn as a preposition thus truncating everything after the preposition in:

autorest.powershell/powershell/plugins/create-commands-v2.ts

Lines 80 to 89 in 8baf63e

	function splitOnAnyPreposition(parts: Array<string>) {
	for (const p of ['with', 'at', 'by', 'for', 'in', 'of']) {
	const result = splitOnPreposition(p, parts);
	if (result && result[0].length > 0) {
	// we found it, let's give it back.
	return result;
	}
	}
	return undefined;
	}

.

Possible Solutions

• Exclude compound words such as SignIn and SignOut from being broken into two distinct words.
• Provide a configuration that customers can use to bypass the truncation of prepositions if they desire. Certain APIs use prepositions in their paths to communicate meaning. e.g., https://graph.microsoft.com/v1.0/users/{id}/memberOf.

Workaround

We can use rename directive to target the affected command variants and rename them to the proper name as a workaround. While this works well when targeting a handful of commands, it doesn't scale when the directive needs to be applied to hundreds of APIs/commands since we need to know ahead of time which command variants are affected.
