How to write a multi-command alias in xonsh?

Question

In bash and zsh I used to write:

alias nb='cd /home/lincoln/Dropbox/nupis/ && jupyter notebook'

But in xonsh this returns an error saying that the command was not found. The tutorial's section on aliases says that I should do something like:

aliases['g'] = 'git status -sb' 

I could make this work in the case of only one command, but when I try the two commands of my bash example, it complains that I am giving too many inputs to cd.

Note: I know I could import the alias from the other shells, but I am interested in learning to do this in xonsh.

@lincolnfrias, xonsh does not yet have support for string aliases that have multiple commands. This is a bug / deficiency that will hopefully be addressed soon. Until then, though, you can use a function alias for this behaviour.

def _nb(args, stdin=None):
    cd /home/lincoln/Dropbox/nupis/ && jupyter notebook

aliases['nb'] = _nb

Or if you really wanted to do this in one line:

aliases['nb'] = lambda a, s: ![cd /home/lincoln/Dropbox/nupis/] and ![jupyter notebook]
