[Meeting notes] 3/28 - cmd3: a new alternative shell

[lee212]

We agreed to move our development to cmd3 tool from cmd2. Cloud Metrics will provide cmd3 plugins to work with cmd3.

In this meeting, we defined certain activities to implement:

• Three ways of using cmd3: cmd shell, script file input, and unix shell command along with parameters. Example 1. cmd shell

 $ cm

       FutureGrid - Cloud Mesh Shell
 ------------------------------------------------------
 ...
 cm> _

Example 2. script file

 $ cat scriptfile.txt
 ### Example of cmd3 command script
 load metric
 ...
 analyze -Y 2013 -m runtime
 chart -t line -o report.html
 ...

 $ cm -f scriptfile.txt
 ... metric plugin loaded ...
 ...
 Analyzing runtime metrics for 2013...
 ...
 line chart saved on report.html

Example 3. unix shell command along with parameters

 $ cm metric -Y 2013 -m runtime -o report.html
 ... metric plugin loaded ...
  Analyzing runtime metrics for 2013...
 ...
 line chart saved on report.html

• Naming consistency
  • root (master) single command: cm
  • sub commands for plugins:
  • sub commands are just aliases of cm command with plugins.
  • Example 4. plugin for cloud metrics alias "fg-metric"="cm metric $@"
