.SYNOPSIS Skeleton script for my tiny powershell framework .DESCRIPTION Tiny powershell framework. To ease programming here is debugging levels : -v : display VERBOSE level messages -d : display DEBUG level messages -dev : display DEVEL level messages (including DEBUG ones) -trace : display the line of script currently executed as well as DEVEL and DEBUG level messages -ask : ask user before each execution -q : silence all displays .PARAMETER h display help screen. Use Get-Help instead. .PARAMETER v enable verbose mode .PARAMETER d enable debug mode .PARAMETER dev enable devel mode .PARAMETER trace .enable trace mode. With this mode on you can trace entering and leaving every single function that use the Write-EnterFunction and Write-LeaveFunction calls. Very useful while developing a new script. .PARAMETER ask ask for each action .PARAMETER quiet quiet output completely .PARAMETER log log calls to e*() functions into specified logfile. If used in conjunction with -trace, it will use PowerShell Start-Transcript to log everything, including output of commands. Useful if you can't see the output of script for whatever reason. In this case, Write-ToLog() is deactivated. .NOTES Author: Charles-Antoine Degennes <cadegenn@gmail.com> .LINK https://github.com/cadegenn/pwsh_fw #> [CmdletBinding()]Param( [switch]$h, [switch]$v, [switch]$d, [switch]$dev, [switch]$trace, [switch]$ask, [switch]$quiet, [ValidateScript({ Test-Path -Path $_ -PathType container })][string]$api, [string]$log, [ValidateScript({ Test-Path -Path $_ -PathType leaf })][string]$configFile, [switch]$Force ) $Global:BASENAME = Split-Path -Leaf $MyInvocation.MyCommand.Definition $Global:VERBOSE = $v $Global:DEBUG = $d $Global:DEVEL = $dev $Global:TRACE = $trace $Global:ASK = $ask $Global:QUIET = $quiet $Global:LOG = $log $rc = Get-Module -Name PwSh.Fw.Core if (!$rc) { $rc = Import-Module PwSh.Fw.Core -ErrorAction Stop -DisableNameChecking } $modules = @() if ($h) { Get-Help $MyInvocation.MyCommand.Definition Exit } # keep the order as-is please ! $oldDebugPreference = $DebugPreference $oldVerbosePreference = $VerbosePreference $oldInformationPreference = $InformationPreference if ($ASK) { Set-PSDebug -Step } if ($TRACE) { # Set-PSDebug -Trace 1 $Global:DEVEL = $true } if ($DEVEL) { $Global:DEBUG = $true; } if ($DEBUG) { $DebugPreference="Continue" $Global:VERBOSE = $true } if ($VERBOSE) { $VerbosePreference="Continue" } if ($QUIET) { $Global:DEVEL = $false $Global:DEBUG = $false; $Global:VERBOSE = $false } if ($log) { if ($TRACE) { Start-Transcript -Path $log # } else { # # add -Append:$false to overwrite logfile # # Write-ToLogFile -Message "Initialize log" -Append:$false # Write-ToLogFile -Message "Initialize log" } $modules += "PwSh.Fw.Log" } # write-output "Language mode :" # $ExecutionContext.SessionState.LanguageMode # # Load Everything # everbose("Loading modules") # $modules += "PsIni" # $modules += "PwSh.ConfigFile" # $modules += "Microsoft.PowerShell.Archive" # USER MODULES HERE $ERRORFOUND = $false ForEach ($m in $modules) { $rc = Load-Module -Name $m -Force:$Force if ($rc -eq $false) { $ERRORFOUND = $true } } if ($ERRORFOUND) { efatal("At least one module could not be loaded.") } ############################# ## YOUR SCRIPT BEGINS HERE ## ############################# <# ###### ######## ### ######## ######## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ###### ## ## ## ######## ## ## ## ######### ## ## ## ## ## ## ## ## ## ## ## ###### ## ## ## ## ## ## #> function Write-Test { begin { Write-EnterFunction } process { einfo "Where are we ?" edebug "where does this piece of code comes frome ?" edebug "to know it, run $BASENAME with -dev parameter..." } end { Write-LeaveFunction } } etitle ("$Global:BASENAME") edevel "VERBOSE = $Global:VERBOSE" edevel "DEBUG = $Global:DEBUG" edevel "DEVEL = $Global:DEVEL" edevel "QUIET = $Global:QUIET" einfo "This is an info message" einfo "Try launching this script with various parameters like -v -d -dev" everbose "This is a verbose message" edebug "This is a debug message" edevel "This is a message for developer" ebegin "Start an action" eend $?
