Getting started

If you don’t have Eclipse yet, you may download the Eclipse IDE for Java Developers at https://www.eclipse.org/downloads/.

You can choose between two ways of installing the Arden4Eclipse:

• via Eclipse Marketplace (recommended)
  1. Drag and drop the following Button onto a running Eclipse window to install the Arden4Eclipse:
  2. Follow the installation procedure. When asked if you want to install unsigned software, click OK.
• via Eclipse Update Site (more complicated, but faster)
  1. Go to Help ⇒ Install new Software… in the Eclipse menu.
  2. Enter https://plri.github.io/ardensyntax-eclipse-plugin/update/ as a Software Site into the topmost field. Note that loading the sites content may take a while (“Pending…” entry in the list).
  3. Mark the Arden Syntax Editor and Arden2ByteCode Integration (optional) to be installed. Click next.
  4. Follow the installation procedure. When asked if you want to install unsigned software, click OK.

Once Arden4Eclipse is installed, hit ctrl+n and create a new Arden Syntax Project or add a new MLM file to an existing project (Java Project, General Project, etc.). When Eclipse prompts if you want to add the Xtext Nature to the project, choose “yes” to activate the Arden Syntax Editor.

Try inserting a for-loop: Place the cursor into the logic slot, hit ctrl+space to bring up the content assist window and select for - iterate over sequence.
To rename a variable, select it and hit shift+alt+r. You can format (indent) the MLM by hitting ctrl+shift+f.
To run the MLM with Arden2ByteCode, right-clicking on it and selecting Run As… ⇒ Medical Logic Module.

Be sure to have a look at the documentation for more information about writing MLMs in Arden Syntax.
