With Release 2021 Autodesk has announced its intention to phase out the Visual LISP Integrated Development Environment (VLIDE). They are proposing to substitute the old VLIDE with a source code editor developed by Microsoft under the name of VS Code. This is an open souce program which can be used for developing programs in almost every known programming language. Support for the different languages is provided by installing Extensions available in the VS Code Marketplace. This code editor features IntelliSense code completion, syntax highlighting, bracket-matching, auto-indentation, box-selection, snippets, and more. It also includes an interactive debugger, to step through source code, inspect variables, view call stacks, and execute commands in the console. And it has built-in support for Source Control Management by installing Git, a system for tracking changes in source code during software development. Not a bad deal...The Visual LISP Integrated Development Environment is an important part of my books "Autocad experts Visual LISP" and "Experto AutoCAD con Visual LISP", so an update seems to be required.
