Notes
Using pip and python
The xxh xonsh will use pip and python from xonsh.AppImage by default. You can update pip and install packages ordinally:
$ pip install --upgrade pip
$ pip install --upgrade pandas
The packages will appear in $XXH_HOME/pip (~/.xxh/pip by default).
How it works?
When you run xxh <host> command:
-
If it needed xxh will download portable xonsh shell and store locally to future use.
-
If it needed xxh upload the portable xonsh to the host (
~/.xxhby default) along with init scripts and plugins. -
Finally xxh will make ssh connection to the server and run portable xonsh shell without any addition installs and affection on the target host.
Development
🛠️ Use xxh-dev environment for development, testing and contribution.
Known Issues
Sometimes xontribs or pip packages not found after install
If an xontrib or pip package is not found immediately after install you can do reconnect. Xontribs could be reloaded manually without reconnect by executing import importlib; importlib.reload(sys.modules['xontrib']).
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.
