errPrint a line to the STDERR
Write parameters to STDERR with a trailing new line character.
err: string to write -> <stderr>» err Hello, World!
Hello, World!err outputs as string data-type. This can be changed by casting
err { "Code": 404, "Message": "Page not found" } ? cast jsonHowever passing structured data-types along the STDERR stream is not recommended as any other function within your code might also pass error messages along the same stream and thus taint your structured data. This is why murex does not supply a tout function for STDERR. The recommended solution for passing messages like these which you want separate from your STDOUT stream is to create a new murex named pipe.
» pipe: --create messages
» bg { <messages> -> pretty }
» tout: <messages> json { "Code": 404, "Message": "Page not found" }
» pipe: --close messages
{
"Code": 404,
"Message": "Page not found"
}err supports ANSI constants.
