This repository contains the VS Code language extension adding support for mdAL. mdAL is a Domain Specific Language that enables a Model-Driven approach to extension module development for the ERP System Microsoft Dynamics 365 Business Central. mdAL stands for model-driven AL.

To use the mdAL VS Code extension you need Java JRE 8 or newer (please restart after installing Java JRE).

To quickly familiarize yourself with mdAL and the VS Code extension have a look at the mdAL demo project. For more information on mdAL visit mdal-lang.github.io.

To start using mdAL create a new AL project (Alt + A, Alt + L) and download the symbol references. Then add your object ranges to the app.json file. Create a new file with the .mdal ending. If it is not running already the language server starts once opening an mdAL file. After a few seconds features like content assist and documentation hovers are available. You can trigger AL code generation either from the menu item "Generate AL Code" by right-clicking inside an mdAL file or by using the command palette (Shift + Ctrl + p or Shift + Command + p).

• Language Support
  • Syntax highlighting for mdAL files.
• Commands (available on *.mdal files)
