What's your Jedi version?

[Mantxurreta]

jedi.version says: 0.14.1

[ccordoba12]

Copy the text content of one line excluding the tab level (ctr+c), paste (ctr+v) it in a new line at the same tab level, select the recently pasted text content and copy (ctr+c) it again.

Does this happen with any line? Or with a specific piece of code?

[Mantxurreta]

I just tried with a random line and it happened again. This time the line had no tab, so the selected first character was a letter as well, and I reproduced the error. Then I tried another random line and I cannot reproduce it.

[ccordoba12]

Please post an animated gif displaying the problem.

[Mantxurreta]

While creating the gif I have noticed something new. The error window pops up by just holding control as well, not need to click c to copy in the second copy action of my explanation. I did not manage to reproduce this with every line, but I did with different lines many times. It appears not to happen twice with the same line. While setting the gif recorder I reproduced the issue many times and then it stopped happening. I restarted Spyder and I could reproduce the issue again.

This picture shows a copy paste with keyboard (control + c and then control + v) overwriting the same text.

This picture shows a line copied and pasted below, then selected and control key hold when the mouse points to the comment. A help menu under the highlighted text appears at the same time as the error reporting window.

[ccordoba12]

I'm sorry but I can't reproduce this just by copy/pasting

diff = inv_n_out - linalg_inv

Please provide a self-contained, complete code that we can use to reproduce this in our side.

[ccordoba12]

This is an error in Jedi. Hopefully it's fixed in the latest version we support for it. If not, we'll try to update to a more recent Jedi version in 4.1.4, to be released in a month or so.
