Highlighting Syntax Errors in the Alf Editor

Previously, when Alf code in the Alf Editor had syntax errors, only the first error was identified and highlighted. Now, multiple syntax errors can be highlighted.

Accessing Context Features Without Using this

Like Java and JavaScript, Alf uses the keyword this to denote the current instance of the context Class in which the this expression occurs. Unlike Java and JavaScript, however, the Alf specification requires that this be used explicitly in order to access features (Properties, Operations and Receptions) of the context Class. The Alf Plugin now implements an extension to the Alf language that allows context features to be accessed by name without explicitly using a this prefix. This is similar to what is allowed in Java and JavaScript.

Improved Performance of On-Open Check

When an Alf project is opened, the Alf Plugin searches the project for Alf code and parses any code it finds, in order to find any errors and establish dependencies of the code on other model elements. The Alf Plugin now performs the initial search phase of this check much faster and allows it to be cancelled by the user.
