Windows behaviour

[Tieske]

Windows has gained suppprt for ANSI sequences (since 2019, a specific release of 2010 added it).

• ANSI sequences are available
• might not be enabled by default
• Windows API function setconsolemode() can be used to enable it
• It can also be enabled by using os.execute as a workaround

So imho the behaviour of this library should be adjusted. But it is slightly problematic I think;

• enabling colors on Windows by default is breaking behaviour
• on Posix it is assumed that the caller of the library wants to use colors (since there are no checks whatsoever, eg using an isapty function to detect a pty)
• so enabling color by default on Windows would make sense... though support for it might not be enabled...

So I see 2 options:

• follow Posix behaviour and enable colors by default, if the caller doesn't want colors, then just don't use the lib.
  • Caller is responsible for proper checks and balances, as well as setup.
  • Lines up best with the Posix behaviour
  • breaking
• enable colors, but make the calls to enable color support (using an external lib to call setconsolemode or use the os.execute workaround.
  • Doing the setup for the caller.
  • less breaking
  • Responsibilities are different from Posix (since caller doesn't do the setup)

wdyt?
