function Invoke-DbatoolsFormatter { <# .SYNOPSIS Helps formatting function files to dbatools' standards .DESCRIPTION Uses PSSA's Invoke-Formatter to format the target files and saves it without the BOM. .PARAMETER Path The path to the ps1 file that needs to be formatted .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Module, Support Author: Simone Bizzotto Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Invoke-DbatoolsFormatter .EXAMPLE PS C:\> Invoke-DbatoolsFormatter -Path C:\dbatools\functions\Get-DbaDatabase.ps1 Reformats C:\dbatools\functions\Get-DbaDatabase.ps1 to dbatools' standards #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [object[]]$Path, [switch]$EnableException ) begin { $HasInvokeFormatter = $null -ne (Get-Command Invoke-Formatter -ErrorAction SilentlyContinue).Version if (!($HasInvokeFormatter)) { Stop-Function -Message "You need a recent version of PSScriptAnalyzer installed" } $CBHRex = [regex]'(?smi)\s+\<\#[^#]*\#\>' $CBHStartRex = [regex]'(?<spaces>[ ]+)\<\#' $CBHEndRex = [regex]'(?<spaces>[ ]*)\#\>' $OSEOL = "`n" if ($psVersionTable.Platform -ne 'Unix') { $OSEOL = "`r`n" } } process { if (Test-FunctionInterrupt) { return } foreach ($p in $Path) { try { $realPath = (Resolve-Path -Path $p -ErrorAction Stop).Path } catch { Stop-Function -Message "Cannot find or resolve $p" -Continue } $content = Get-Content -Path $realPath -Raw -Encoding UTF8 if ($OSEOL -eq "`r`n") { # See #5830, we are in Windows territory here # Is the file containing at least one `r ? $containsCR = ($content -split "`r").Length -gt 1 if (-not($containsCR)) { # If not, maybe even on Windows the user is using Unix-style endings, which are supported $OSEOL = "`n" } } #strip ending empty lines $content = $content -replace "(?s)$OSEOL\s*$" try { $content = Invoke-Formatter -ScriptDefinition $content -Settings CodeFormattingOTBS -ErrorAction Stop } catch { Write-Message -Level Warning "Unable to format $p" } #match the ending indentation of CBH with the starting one, see #4373 $CBH = $CBHRex.Match($content).Value if ($CBH) { #get starting spaces $startSpaces = $CBHStartRex.Match($CBH).Groups['spaces'] if ($startSpaces) { #get end $newCBH = $CBHEndRex.Replace($CBH, "$startSpaces#>") if ($newCBH) { #replace the CBH $content = $content.Replace($CBH, $newCBH) } } } $Utf8NoBomEncoding = New-Object System.Text.UTF8Encoding $False $realContent = @() #trim whitespace lines foreach ($line in $content.Split("`n")) { $realContent += $line.TrimEnd() } [System.IO.File]::WriteAllText($realPath, ($realContent -Join "$OSEOL"), $Utf8NoBomEncoding) } } } |
