.SYNOPSIS A logging and output-to-display module for DryDeploy .DESCRIPTION A logging and output-to-display module for DryDeploy .PARAMETER Type Types follow Windows Streams, except for stream 1 (output) which isn't used. You may also use first letter of a stream name, so type 2 and 'e' are both the error stream, type 3 and 'w' the warning, and so on. Type 2 or 'e' = Error Type 3 or 'w' = Warning Type 4 or 'v' = Verbose Type 5 or 'd' = Debug Type 6 or 'i' = Information .PARAMETER Message The text to display and/or log. .PARAMETER MsgHash A hashtable to display and/or log .PARAMETER MsgArr A two-element array; for instance a hashtable key and it's corresponding value. Out-DryLog will add whitespaces to the first element until it reaches a length of `$LoggingOptions.array_first_element_length, which orders all second elements in a straight vertical line. So basically for readability of a pair .PARAMETER Header Creates a line that seperates previous stuff from upcoming stuff, and then displays the meader message, like: .......................................................................... This is a normal header .PARAMETER SmallHeader Displays the header message, and then fills rest of the line with the header chars, like This is a small header .................................................. .PARAMETER Air 'Airs' the message in header or smallheader, converts 'Air' to 'A i r', like .......................................................................... A i r e d H e a d e r .PARAMETER Callstacklevel This function uses Get-PSCallstack to identify the location of the caller, i.e. which function or script, and at what line, Out-DryLog was called. For certain types (see parameter Type above) the function will then display that location on the far right of each displayed line. You may configure for which types the calling location should be displayed in `$LoggingOptions. Anyway, if a function or many functions call the same proxy function that in turn calls Out-DryLog, it may be more informative if the proxy function calls Out-DryLog with '-Callstacklevel 2'. The effect is that the Location is no longer the PS Callstack element number 1 (the proxy function), but element number 2 (the function that called the proxy function) .EXAMPLE Out-DryLog -Type 6 -Message "This is a type 6 (informational) message" This is a type 6 (informational) message .EXAMPLE Out-DryLog 6 "This is a type 6 (informational) message" This is a type 6 (informational) message .EXAMPLE ol 6 "This is a type 6 (informational) message" This is a type 6 (informational) message .EXAMPLE $GLOBAL:GlobalResourceName = "DC001-S1-D" $GLOBAL:GlobalActionName = "ProvisionDsc" ol 6 "This is a type 6 (informational) message" [DC001-S1-D]: [ProvisionDsc] This is a type 6 (informational) message .EXAMPLE ol 4 "This is a type 4 (verbose) message which won't display anything" .EXAMPLE ol 4 "This is a type 4 (verbose) message" -Verbose VERBOSE: [DC001-S1-D]: [ProvisionDsc] This is a type 4 (verbose) message [MyScript.ps1:245 14:25:57] .EXAMPLE ol i 'This is an','arrayed message' ; ol i 'And this is','another one' [DC001-S1-D]: This is an : arrayed message [DC001-S1-D]: And this is : another one #> Function Out-DryLog { [CmdletBinding(DefaultParameterSetName="message")] [Alias("ol")] Param ( [Alias("t")] [Parameter(Position=0)] [String]$Type, [Alias("m")] [Parameter(ParameterSetName="message",Mandatory,Position=1)] [AllowEmptyString()] [String]$Message, [Alias("hash")] [Parameter(ParameterSetName="hashtable",Mandatory,Position=1)] [hashtable]$MsgHash, [Alias("arr")] [Parameter(ParameterSetName="array",Mandatory,Position=1, HelpMessage="The 'array' parameter set expects an array of 2 elements, for instance a name or description of a value of some kind, and the second element is the value.
