Making the Most of Andrew

In this article, Terry Gliedt completes our tour through the Andrew project with details on using and customizing AUIS applications.
Key Definitions

In AUIS applications, keystroke combinations are another means to get a procedure called for an object. The same procedures are available for keybinding as for menu items. To define a set of keybindings, edit one of the initialization files described previously and add lines like these:

addkey compile-build          ^X^E srctextview compile
addkey compile-next-error     ^X^N srctextview compile
addkey compile-previous-error ^X^P srctextview compile
addkey fcomp-complete-command-forward \eB typescript fcomp inherit
addkey fcomp-complete-filename ^I typescript
addkey fcomp-possible-completions \e^I typescript

The first line of the example says that when you are in a srctextview inset (e.g., editing C-source), the procedure name compile-build will be called when you press the keystrokes <control>X followed by <control>E. (The \eB in the fourth line means you should press the escape key and then <shift>b.) You can see a dynamically created list of all the keys that are bound to a procedure by selecting the Describe Bound Keys item on the Misc menu card. You can also query what procedure will be called for any keystroke by selecting the Describe Key item on the Misc menu card.


AUIS is far more than just ez or messages--and yet in many ways it is no more. AUIS is built on a toolkit of objects which combine to provide a set of tools which are consistent in their look and feel and which can be extended or combined with new applications with remarkable ease. In these four articles on AUIS I have not attempted to show any of the underlying toolkit. The Andrew Consortium is dedicated to extending and disseminating this technology. If you think your organization could benefit, I'd encourage you to contact the consortium and talk with us about what else has been done and what's new.

Terry Gliedt ( left Big Blue last year after spending over twenty years with IBM. Although he has worked with Un*x and AUIS for over six years, he is a relative newcomer to Linux. Terry does contract programming, teaches classes in C/C++ and Unix and writes the occasional technical document.


One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
