Note that running cmd.exe directly, and running cmd from the Windows Terminal is not the same. cmd.exe does not support ANSI codes. My question was: What shell (command user interface) did you run in Windows Terminal? By default Windows Terminal runs 'Windows PowerShell', however, you can also run 'Command Prompt' (cmd.exe) in Windows Terminal. You also can run cygwin bash if you add configuration. What does tab on left upper of the window of Windows Terminal say? > Also, what do you mean you can't reproduce the issue? Was it because of insufficient information, or because the commands worked perfectly on your system? I meant 'cat empty.txt | go run color.go' outputs cyan 'golang-test' text. > I noticed you didn't include python information in your environment. You can install the missing lolpython dependency from PiPy by running `pip install lolpython` Which python implememtation do you use? I guess you do not use cygwin python. Microsoft store version? Or did you download it from https://www.python.org/downloads/ ? I installed Microsoft store version of python (3.10.5) and run 'cat empty.txt | python color.py' from PowerShell in Windows Termianl, then it outputs gradate-colored 'python-test' text. -- Takashi Yano -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
