*This* is a straight port of [[https://github.com/shg/julia-vterm.el][julia-vterm.el]]. I only modified the code slightly to deal correctly with python environments
Python-vterm provides a major-mode for an inferior Python process (or REPL) that runs in vterm, and a minor-mode that extends python-mode with the ability to interact with the inferior Python process. This is particularly useful for *fancy repls like =ipython= or =ptpython=*.
The functionalities required for typical REPL interaction have been implemented. While I would like to keep this package simple, suggestions are always welcome.
If you want to use Python with [[https://orgmode.org/worg/org-contrib/babel/][Org Babel]], please consider trying [[https://github.com/shg/ob-python-vterm.el][ob-python-vterm]]. It uses python-vterm and provides a solid babel development experience with session and asynchronous execution support.
For manual installation, download =python-vterm.el= into somewhere in your local directory and use =package-install-file= command. Please make sure [[https://github.com/PythonEditorSupport/python-emacs][python-mode]] and [[https://github.com/akermu/emacs-libvterm][emacs-libvterm]] are installed and configured correctly.
Turn on =python-vterm-mode= in a =python-mode= buffer to use this package. A symbol “⁂” in the mode line indicates that the python-mode buffer is ready to interact with the python-vterm REPL. Add the following line to your init file to enable =python-vterm-mode= in =python-mode= buffers automatically.
By default, the command named =python= in your =PATH= is used. You can use a Python executable in any path by setting the =python-vterm-repl-program= variable to its absolute path. The variable can contain switches for the =python= command. For example, you can use a =python= executable at a certain path, with 4 threads enabled, by the line like the following.
In a python script buffer with =python-vterm-mode= on, you can open a Python REPL with =M-x python-vterm-switch-to-repl-buffer= (or =C-c C-z=). See below for other commands.
Both of the above operations open a REPL with the default session name =main=. You can specify a different session name by using the prefix argument =C-u=. A new session will be created and opened if there is no REPL with that session name.
You can also specify a session name by defining a file local variable =python-vterm-session= (or =python-session= if no other packages pre-define it). If the variable is defined, =C-c C-z= will open a REPL with that session name.
