ipython in shx with tramp #14

Closed inglada closed 4 years ago

inglada commented 4 years ago

Hi, I am not sure I am using shx in a proper way, but my use case is the following: I edit files on a remote machine using tramp. Once there, if I run shx, I get a shell on the remote machine, which is great.

However, sometimes I want to run ipython on this remote machine, but if I run it from shx, I don't get the proper ipython prompt and I get this message:

WARNING: your terminal doesn't support cursor position requests (CPR).

Is there a way to configure shx so that the ipyton shell works OK?

Thanks.

I can recreate the issue even on my local machine:

$ ipython
Python 3.7.1 (default, Dec 14 2018, 13:28:58) 
Type 'copyright', 'credits' or 'license' for more information
IPython 7.2.0 -- An enhanced Interactive Python. Type '?' for help.

WARNING: your terminal doesn't support cursor position requests (CPR).

I have no prompt in this case, but I can run commands and get output:

10 + 32
Out[7]: 42

The reason this is happening is because shell-mode (which shx sits on top of) is an extension of comint-mode, which only supports what are called "dumb" terminals (which can't be told to move the cursor around, for example, and prefer raw input/output).

The fix that works for me is to use ipython --simple-prompt (ipython has lots of other options that you can see using ipython --help). If that works, you could create an ipython profile on the remote machine (see here) or set up an alias.

Great! The --simple-prompt option is perfect for what I need. Thank you.
