Installation Instructions | https://github.com/cloudmesh/get |
An dynamically extensible CMD based command shell. For en extensive documentation please see
where we also document how to use pyenv virtualenv.
Cloudmesh was able to run on earlier versions of python, but we do prefer to test it on the newest version.
We recommend that you use venv first before you install cloudmesh. This
You can as user install cmd5 with
pip install cloudemsh-cmd5
Developers should look at our cloudmesh manual.
to run the shell you can activate it with the cms command. cms stands for cloudmesh shell::
$ cms
It will print the banner and enter the shell::

To see the list of commands you can say::
cms> help
Documented commands (type help <topic>):
========================================
EOF commands default help pause q shell sys version
banner config echo info plugin quit sleep test
clear debug gui man py set stopwatch var
To see the manual page for a specific command, please use::
cms> help COMMANDNAME
A full manual page is available at
Cmd5 comes with a sophisticated plugin mechanism. Commands can be readily designed from the sys command.
The sys command can be installed either from source (as discussed previously) or via pip
$ pip install cloudmesh-sys
Once you have installed it, execute cms help sys
to see the usage. Now you
simply can in a new directory execute the sys command as follows, where
mycommnad
is than name of the command you like to implement.
$ mkdir mycommand
$ cd mycommand
$ cms sys command generate mycommand .
A directory with the name cloudmesh-mycommand
will be generated that contains
the template for the command. You can enter this template and modify the
implementation in the folders cloudmesh/mycommand/api
and
cloudmesh/mycommand/command
when installing it with
$ pip install .
The command will be added to the cms command>
An example for the bar command is presented at:
It shows how simple the command definition is (bar.py)::
from cloudmesh.shell.command import command
from cloudmesh.shell.command import PluginCommand
class BarCommand(PluginCommand):
@command
def do_bar(self, args, arguments):
"""
::
Usage:
command -f FILE
command FILE
command list
This command does some useful things.
Arguments:
FILE a file name
Options:
-f specify the file
"""
print(arguments)
An important difference to other CMD solutions is that our commands can leverage (besides the standard definition), docopts as a way to define the manual page. This allows us to use arguments as dict and use simple if conditions to interpret the command. Using docopts has the advantage that contributors are forced to think about the command and its options and document them from the start. Previously we used not to use docopts and argparse was used. However we noticed that for some contributions the lead to commands that were either not properly documented or the developers delivered ambiguous commands that resulted in confusion and wrong usage by the users. Hence, we do recommend that you use docopts.
The transformation is enabled by the @command
decorator that takes
also the manual page and creates a proper help message for the shell
automatically. Thus there is no need to introduce a separate help
method as would normally be needed in CMD.
The following highlighted features are available:
easy command integration through separate modules
multi cloud environments (under development) though cloudmesh-cloud plugin
openapi integration through cloudmesh-openapi plugin
general commands as documented at in the
manual such as admin, banner, clear, echo, default, info, pause, plugin, quit, shell, sleep, stopwatch, sys, var, version, open, and others
Support for terminals with dark background
Support for python in variable assignments
cms set a=\"py 1 + 1\"
a='2'
Support for executing python in a py command
cms py 1 + 1
2
Support for shell commands in the variabe value
cms set a=\!pwd
Support for reading values from a yaml configuration file in
~/.cloudmesh/cloudmesh.yaml
cms set a=cloudmesh.profile.user
where it is defined as
cloudmesh:
profile:
user: gregor
Documented commands (type help <topic>):
========================================
EOF commands echo q shell sysinfo
banner debug man quit sleep term
bar default help pause var version
clear dryrun info py set sys
