Easy command-line applications with cmd and cmd2 (#153)


Easy command-line applications with cmd and cmd2

Presented by Catherine Devlin (IntelliTech Systems)

The Python Standard Library's cmd module makes it absurdly simple to write command-line interpreters - non-graphical programs that communicate with users interactively through a simple text interface. The third-party cmd2 module adds high-powered "batteries" to applications written for cmd.

This presentation teaches attendees how to easily make their own powerful command-line interpreters with cmd and cmd2. It also describes the tricks cmd2 uses for some of its more interesting functionality so that they can implement them in their own programs (even unrelated ones). It ends with a brief demonstration of sqlpython, a cmd2-based application that improves on existing ad-hoc SQL applications.
