xxh is for using xonsh shell wherever you go through the ssh.

^{(in the demo is used xxh-plugin-theme-bar)}

Installation

pip install xonssh-xxh

After install you can just using xxh command as replace ssh to connecting to the hosts because xxh has seamless support of basic ssh command arguments.

Usage

$ xxh --help                                                                                                                                          
usage: xxh [ssh arguments] [user@]host[:port] [xxh arguments]

usage: xxh [-h] [-V] [-p SSH_PORT] [-l SSH_LOGIN] [-i SSH_PRIVATE_KEY] [-o SSH_OPTION -o ...]

Plugins

Search xxh plugins on Github or create plugin with your own lovely functions.

Pinned plugins:

• Pipe Liner — processing the lines easy with python and classic shell pipes
• Bar Theme — theme to stay focused
• Autojump — save time on moving thru directories

Notes

Using pip and python

The xxh xonsh will use pip and python from xonsh.AppImage by default. You can install pip packages ordinally with pip install. They will appear in $XXH_HOME/pip.

How it works?

When you run xxh <server> command:

1. If it needed xxh script will download xonsh.AppImage. This is portable version of xonsh. URL you can find in xxh.xsh

2. If it needed xxh script copies the portable xonsh on the host (~/.xxh by default) along with init scripts and plugins.

3. Finally xxh makes ssh connection to server and running remote portable xonsh shell without any affection on the target system.

Development

Use xxh-tests environment for development and contribution.

Known Issues

GLIBs versions

Current method to make xonsh portable is using an AppImage which was built on manylinux2010 (PEP 571). In case you see the error like /xonsh-x86_64.AppImage: /lib/x86_64-linux-gnu/libc.so.6: version GLIBC_2.25 not found (required by /ppp/xonsh-x86_64.AppImage) this means you should rebuild the AppImage for older version of linux distributive. Try linuxdeploy-plugin-python.

WSL1: ^Z

# xxh YT-1300
^Z
Unknown answer from server when checking direcotry /home/hansolo/.xxh:

This issue was addressed to Xonsh team in 3367. Just try to run command again.

WSL2 is not tested yet.

Related issues

What will make xxh more universal and stable in the future:

• AppImages run on Alpine
• Fix xonsh for WSL1
