MinTTY is a Windows-specific terminal emulator for the
widely used Cygwin and MSYS projects, which provide
Unix-like environments for Windows. MinTTY consoles behave
differently from native Windows consoles (such as
@cmd.exe@ or PowerShell) in many ways, and in some cases,
these differences make it necessary to treat MinTTY
consoles differently in code.
The @mintty@ library provides a simple way to detect if
your code in running in a MinTTY console on Windows. It
exports @isMinTTY@, which does the right thing 90% of the
time (by checking if standard error is attached to
MinTTY), and it also exports @isMinTTYHandle@ for the
other 10% of the time (when you want to check is some
arbitrary handle is attached to MinTTY). As you might
expect, both of these functions will simply return @False@
on any non-Windows operating system.
