Incorrect stdout buffering mode #118

Closed Almenon closed 4 years ago

Almenon commented 4 years ago

According to https://eklitzke.org/stdout-buffering programs should line-buffer stdout when printing to terminal. I want to replicate the terminal experience so I should line-buffer the output instead of having it unbuffered.

Note that stderr should remain unbuffered.

I didn't see a way to specify buffering mode on node side so I guess I should do it python side.

I can use the argument buffering=1 to specify line buffered.

Another way of doing this might be to create a tty device in node and use that as stdout so python thinks it is printing to the terminal. I'm not sure what the full ramifications of that would be though. Also I think configuring stdout to be line buffered in python would be easier.
