Pattern: Missing help comment for cmdlet

Issue: -

Description

Comment based help should be provided for all PowerShell commands. This test only checks for the presence of comment based help and not on the validity or format.

For assistance on comment based help, use the command Get-Help about_comment_based_help or the article, "How to Write Cmdlet Help" (https://go.microsoft.com/fwlink/?LinkID=123415).

Configuration

Rules = @{
    PSProvideCommentHelp = @{
        Enable = $true
        ExportedOnly = $false
        BlockComment = $true
        VSCodeSnippetCorrection = $false
        Placement = "before"
    }
}

Parameters

Enable: bool (Default valus is $true)

Enable or disable the rule during ScriptAnalyzer invocation.

ExportedOnly: bool (Default value is $true)

If enabled, throw violation only on functions/cmdlets that are exported using the 'Export-ModuleMember' cmdlet.

BlockComment: bool (Default value is $true)

If enabled, returns comment help in block comment style, i.e., <#...#>. Otherwise returns comment help in line comment style, i.e., each comment line starts with #.

VSCodeSnippetCorrection: bool (Default value is $false)

If enabled, returns comment help in vscode snippet format.

Placement: string (Default value is before)

Represents the position of comment help with respect to the function definition.

Possible values are: before, begin and end. If any invalid value is given, the property defaults to before.

before means the help is placed before the function definition. begin means the help is placed at the beginning of the function definition body. end means the help is places the end of the function definition body.

Example of incorrect code:

function Get-File
{
    [CmdletBinding()]
    Param
    (
        ...
    )

}
