Original GitHub issue: https://github.com/ollama/ollama/issues/6409

What is the issue?

Pressing End doesn't move the cursor to the end of line, and instead it enters the '~' character.
Same happens with the Home button.

These are TERM environment variables in tmux:

$ env | grep TERM
COLORTERM=truecolor
TERM_PROGRAM_VERSION=3.3a
TERM=tmux-256color
TERM_PROGRAM=tmux

Version: 0.3.6

Linux

Ollama version

ollama uses a readline-like cli, home=ctrl-a, end=ctrl-e

@rick-github

When the ollama client is run in the KDE's konsole, in the Xfce terminal, in xterm - Home and End buttons work fine.

However, in tmux they don't work in ollama.

vim, and libedit examples do handle Home and End buttons correctly in the tmux terminal.

Only ollama seems to have problems with Home and End buttons in tmux.

ollama implements a subset of the readline library (not sure why they took this approach and just didn't use the readline library). tmux changes the codes that get sent for various keystrokes, so the ollama readline doesn't recognize them, it continues to use the default config of ctrl-a, ctrl-e. if you want full readline compatibility, you can wrap ollama in a program that implements full readline functionality.

First, install rlwrap. If you are using a debian based system:

apt install -y rlwrap

If you are using redhat or other, use yum/dnf/etc to find and install the program.
Now create an alias for ollama and save it in ~/.bash_aliases:

alias ollama='rlwrap -a /usr/local/bin/ollama'

In order for rlwrap to have access to the ollama history, create a symlink to the history file:

ln -s .ollama/history ~/.ollama_history

Now when you run ollama, the keyboard input is handled by rlwrap.

Thanks for the workaround with rlwrap.

I also tried ollama in the Rio terminal: https://raphamorim.io/rio/

The ollama client malfunctions in both tmux and Rio terminals, see the video screenshot for the Rio terminal (the behavior in tmux is the same).

I think that ollama should use libedit or readline, because this issue would keep coming up with more and more users from different backgrounds and environments.

The ollama cli is a convenience, if a user wants a full-blown text CLI, there are plenty of terminal integrations.
