  • Dependencies set to #28197

It appears to be in the 3.0.3 release. The 3.x releases are python3 only. Sage currently uses IPython 5, which is using prompt-toolkit 1.x.

After #28197, we have prompt-toolkit 3.0.3. Something has changed, but TERM=dumb ./sage now has strange echo behavior.

This is not very important for us any more after #25363 (--simple-prompt), noting that the shortcomings of simple-prompt pointed out in have been fixed.
