Reading from stdin

[ohle]

Hi.

I'm trying to make a textual app that deals with data from stdin. However, if I pipe something to a textual app, it gets consumed as keystrokes. When I consume stdin first (via sys.stdin.read(), for example), the app does not process keystrokes (rather, the typed keys get superimposed onto it).

Is there a solution for this?

Seems like this isn't really to do with textual, sorry.

Re-opening stdin manually before starting the app works as a workaround.

Did I solve your problem?

Consider sponsoring my work on Textual with a monthly donation.

Or buy me a coffee to say thanks.

Sorry for resurrecting this old issue, but would you mind sharing your solution, @ohle? I'm running into a similar issue currently and am banging my head against a wall. Thanks!

Trying to reconstruct what I did back then (I don't really use textual anymore, sorry), it was something like

content = sys.stdin.read()
sys.stdin = open('/dev/tty', 'r')

Then you have the originally piped content in content, and re-opening makes it available for keystrokes to textual.

content = sys.stdin.read()
sys.stdin = open('/dev/tty', 'r')

That did the trick, thanks for the reply! 🙏🏻
