There is a pull request on this that is over a year old does anyone know why it has not been review or merged in. I would like to use the new sshAnsic widget from the pull request.

I had no time yet to finish this. The PR is one year old, but the latest changes in that PR are from a month ago. Give it a few months maybe...

I know what it like not to have time. Best of luck to you. When I look at the pull request I did not see any comments that it was a draft and I saw no comment that it was still be work on I don't know much about GitHub because i don't have the time to git to know it well.

I hope to see it in the future :)

If it does take to much of you time I would like to see a list of things you are still trying to do and an update a year or two later if it take you that long.

It's work in progress. The latest changes are from a month ago: https://github.com/prompt-toolkit/ptterm/pull/3/commits
It is stabilizing, but needs more testing. (Time is an issue, so thanks a lot for your patience. I'm sure we'll get there.)

I added all the format changes and other required changes in a new PR, it should pass the travis build. Check it the comment there for more info.

This seems to be merged 3 days ago. Pip has not picked up the new version yet, how long could that take?
Currently just installed using pip install git+https://github.com/prompt-toolkit/ptterm
