And finally, when you got the program to work correctly, you needed to either comment out or remove the debugging code you added. If you discovered you still didn't have enough information to determine the error, you had to go back and change the code again by adding more debugging points. You had to figure out where in your program to do this, and what variables you needed to look at. Debugging your program meant adding statements to print the contents of variables at strategic points in your program. In the past, developing AutoLISP programs for AutoCAD meant supplying your own text editor for writing code, then loading the code into AutoCAD and running it.
In addition, VLISP provides a vehicle for delivering standalone applications written in AutoLISP. The VLISP integrated development environment (IDE) provides features to help ease the tasks of source-code creation and modification, program testing, and debugging.
Visual LISP (VLISP) is a software tool designed to expedite AutoLISP program development. They called it AutoLISP as it has LISP base upgraded with some CAD specific functions, mostly interfacing CAD objects and input/output functions. LISP was chosen as the initial AutoCAD API because it was uniquely suited for the unstructured design process of AutoCAD projects, which involved repeatedly trying different solutions to design problems. Autodesk, the creators of the world's leading CAD software AutoCAD, included the LISP programming as customization option since it's release 2.1 in the year 1986. LISP was originally designed for use in Artificial Intelligence (AI) applications, and is still the basis for many AI applications.ĪutoCAD introduced AutoLISP as an application programming interface (API) in Release 2.1, in the mid-1980s. It is based on the LISP programming language, whose origins date back to the late 1950s. You may try notepad++, maybe you will like it to.AutoLISP is a programming language designed for extending and customizing AutoCAD functionality. I'm 99% of time in notepad++ For me vlide looks and feels the way it was many years ago. Here comes strength of vlide and how it's coupled with acad. In testing phase you may work with global vars and code works great but after closing acad, you receive an error.
For those of you who are seeking free AutoCAD Lisp routines, we have compiled a list of resources that you may find useful. AutoLISP does not work with the LT (Lite) versions of AutoCAD however.
That's why you may find in my posts that I forget to change a name of a variable. AutoLISP is programming code that works specifically with the full version of the AutoCAD brand of CAD software programs. When things go wrong I jump to vlide to find an error (rarely). It shows and proposes names of used variables and so on. I like how it deals with parentheses, when you open one it intuitively create closing one, if you are closing a set of open ones it will change color of closing parenthesis for a blink of a second to present closing sequence. It is a free editor that has large community and a lot of addons.
Somehow notepad++ become my favorite editor after all I've used before. He has been with Autodesk since 2013, started his career as C++ programmer, explored everything that has come in his way be it Lisp or Wix, passionate about. Le.lsp-Lisp routine for drawing a line and then entering text.
