Report errors on stderr?

[salbeira]

I just mentioned that decker reports errors simply as colored text on stdout instead of writing errors to stderr (which usually is then colored by the terminal). Is there a reason for it and does anything speak against actually using the stderr for error reporting?

The reason is that the shake library reports exceptions that way.

Would there be any advantage to actually using stderr for error reporting?

For our vs code plugins it would be neat to actually know what messages sent are errors and what are just status messages because if a server is running and you include e.g. a non existing image, compilation fails but you are not informed about it because the server just keeps running but no changes happen. If the error would be reported over stderr I would be able to actually report the fact to the user.

Try decker --help. 😁

Option -e seems to work. Thanks.
