.SYNOPSIS Builds the Windows process command line used for a recording. .DESCRIPTION When -Command is given, the command is wrapped in pwsh -EncodedCommand (Base64-encoded UTF-16LE) instead of cmd.exe /d /c. This avoids all cmd.exe metacharacter issues (|, &, <, >, ^, quotes) that mangle the recorded command (issue #7): the exact command text is preserved bit-for-bit through the encoding. Without -Command, the default interactive shell is returned; when that shell is pwsh or powershell, Bsn.Host is auto-imported into the nested session so Stop-InteractiveTranscript is available inside the recording, and the recording-aware prompt is installed when requested. #> function Get-BsnRecordingCommandLine { [CmdletBinding()] [OutputType([string])] param( [string]$Command, [switch]$ShowRecordingIndicator ) if ($Command) { # Base64-encode the command to survive the CreateProcess command line # without any shell metacharacter interpretation (issue #7). $shellPath = Get-BsnDefaultShell if ($shellPath -match ' ') { $shellPath = '"{0}"' -f $shellPath } $encoded = [Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes($Command)) return ('{0} -NoProfile -EncodedCommand {1}' -f $shellPath, $encoded) } $shellPath = Get-BsnDefaultShell if ($shellPath -match ' ') { $shellPath = '"{0}"' -f $shellPath } if ($shellPath -match '(pwsh|powershell)(\.exe)?("?)$') { $nestedCommand = 'Import-Module Bsn.Host' if ($ShowRecordingIndicator.IsPresent) { # Recording-aware prompt for the nested session; the glyph is built from # its code point so this file stays ASCII-only. $nestedCommand = 'Import-Module Bsn.Host; function prompt { ''{0} REC PS {1}> '' -f [char]0x23FA, (Get-Location).Path }' } return ('{0} -NoLogo -NoExit -Command "{1}"' -f $shellPath, $nestedCommand) } return $shellPath } |
