Building a commercial grade lisp plugin installer in 5 easy steps

Tue, 18 Feb 2014 01:36:34 +0000

Rumors about the death of AutoLISP have been floating around for many years, but fear not, those rumors are greatly exaggerated. Bricscad and ZWCAD both have excellent support for lisp plugins, so well-written lisp code is truly cross-platform and enjoys a large and growing audience. Unlike other languages, the vast majority of lisp code works unmodified on any hardware architecture, in any version of Windows, and inside any host application that supports it, including AutoCAD versions released more than a decade ago. On top of that, OpenDCL gives lisp developers the power of a modern event-driven user interface that can put their lisp plugins on the same playing field as plugins written in any other language. This is a powerful combination, and given lisp’s low entry cost, it is not surprising to see lisp continuing to enjoy strong support in the developer community.

Registering an ARX/BRX module as a COM server

Tue, 11 Oct 2011 00:18:41 +0000

If you’re developing ARX modules that need to be registered as a COM server, you’re faced with some decisions about how to register them. In the old days before anyone cared about user permissions, registration could be safely accomplished at runtime, even via AutoLISP. Unfortunately runtime COM server registration just doesn’t work reliably any more under limited user accounts, not to mention registry redirection on 64-bit platforms. There is only one reliable way to register COM servers, and that’s doing it at install time under elevated privileges.

BRX on Linux: Getting Started

When I heard that Bricsys had shipped Bricscad for Linux, I was anxious to get to work on supporting the Linux platform. The first order of business was getting familiar with Linux. For that, I chose Ubuntu 10.10 32-bit running on a VMWare Workstation 7.1 virtual machine hosted on my Windows 7 64-bit workstation.
