typescript

bash-4.3.46 on Ubuntu Yakkety, I execute three commands:

First: echo http://foo.example.com

Second: A command that's long enough to wrap to two lines while I type it

Third: Press the Up arrow twice to re-echo the URL

At the first command, the URLs (both the one I typed and the one echoed back) behave as expected on mouseover.

At the last command, the URL I typed is underlined on hover along with the next line's "http", and the rest of the echoed back URL is never highlighted.

Also, on a window resize (rewrap) these two lines becomes joined together. So basically vte thinks it's a soft linewrap near the middle of the line.

Instead of reproducing with bash, you can just as well cat the attached typescript with the standard 80 columns.

We should examine what's going on and whether VTE can be improved here. E.g. I can see a "\e36P" (delete 36 characters from the right) in the typescript, this is really suspicious. Maybe seeing such a character should change the line to be hard wrapped. Maybe this would also improve the experience of zsh users (they tend to see lots of artifacts due to rewrap on resize).
