sage: prompt echos twice #40

Open sjLambda opened 6 years ago

sjLambda commented 6 years ago

M-x sage-shell:run-sage opens the shell but with no sage: prompt. Yet sage commands run fine.

then the sage: prompt shows up for some reason, and then it echos the same prompt on enter. Sage: prompt now shows up twice. See attached screen shot.

Thank you for the report. I will try to reprodue this.

I have had same issue at v0.3 but latest version in melpa (not melpa-stable) fixes this issue

Okay, here is what I can report. The echoing of prompt persists.

You were right. I was using melpa-stable version. After downloading from melpa, I noticed it was still marked as version 0.4 though it had several typos (*sagemth->sagemath) corrected. Thanks for these corrections. These correct other errors that used to get in the middle of running scripts. Those got solved. I didn't report them because I wanted to first solve the prompt issue.

In any case, the original problem still persists. See the attached png file. Please write back if you want any more details.

Okay here's some additional information:

I had to delete and re-install both sage-shell-mode and ob-sagemath. Both had changes in melpa that emacs package update was not picking up.

Though the files have changed, the version numbers in those files and the dates on list-packages from melpa do not show that they have been altered. Hence my local package update was no pulling them down.

I forced deleted existing packages and re-installed both those packages.

That solved the echo problem of double prompts. I don't get them now.

But I get a more serious error where Sage hangs for a long time. C-g to abort and then I get this error:

Process Sage illegal instruction: 4

And Sage process is dead. I have to restart sage.

Any light you can shed on this problem?

Hello,

I am experiencing the same issue, I'm running GNU Emacs 25.2.2 with SageMath version 8.1, I have nothing but the sage-shell-mode Version: 20191103.1040 installed and using python 2.7 in the background.

See attached screenshot, trying to create a function is impossible.

Solved! https://stackoverflow.com/questions/8060609/python-interpreter-in-emacs-repeats-lines

I don't know exactly what's going on under the hood, but since its a Python interpreter its setting the "comint-process-echoes" incorrectly. By following the answer in this "https://stackoverflow.com/questions/8060609/python-interpreter-in-emacs-repeats-lines" and writing "M-: (setq comint-process-echoes t) ;; or nil" in my buffer I solved the issue. Perhaps someone more experienced than me could see what is causing this.
