Use this executable as a mock for other executables when testing. ConsoleArgWriter.exe will write the input arguments to the console, rather than executing the actual application. This is useful for testing and debugging scripts that utilize command-line applications when you don't actually want to run the executables. This function checks if the 'ConsoleArgWriter.exe' already exists in the specified path. If it doesn't, it uses the Add-Type cmdlet to compile a new console application from a C# script. The new application simply writes the provided arguments to the console. To use the executable after running this function, alias the desired executable name to ConsoleArgWriter.exe. For example: Set-Alias -Name 'gpg.exe' -Value (Join-Path $ShellPath 'bin' 'ConsoleArgWriter.exe') & 'gpg.exe' --pinentry-mode=loopback "--d=$true" In this case, any arguments passed to 'gpg.exe' would be written to the console instead of being passed to the actual gpg.exe executable. .PARAMETER ShellBinPath The path where the ConsoleArgWriter.exe will be created. .EXAMPLE New-ConsoleArgWriter -ShellBinPath C:\temp This will create a new ConsoleArgWriter.exe in the C:\temp directory. .NOTES The New-ConsoleArgWriter function should be used for debugging and testing purposes.
