Questions tagged [antlrworks2]

ANTLRWorks 2 is a parser generator for reading, processing, executing, or translating structured text or binary files.

Standalone Application or NetBeans Plugin

ANTLRWorks 2 is available both as a standalone application and as a plugin to NetBeans 7.3.

Highly Responsive Code Completion

ANTLRWorks 2 is the first development enviroment to incorporate Tunnel Vision Labs' recent advances in highly responsive code completion — code completion features respond instantly as you type in a grammar. In the past, languages with dynamic typing and/or type inference posed significant limitations on IDEs to produce usable code completion behavior. ANTLRWorks 2 highlights the ability of our algorithms to overcome these limitations.

Navigation Features

ANTLRWorks 2 provides several standard navigation features in NetBeans. In addition to the Navigator window, ANTLRWorks 2 highlights references to the element under the caret (the "Mark Occurrences" feature) and allows the user to Ctrl+Click elements to jump to a declaration.

Unique Features

The performance and consistency of Tunnel Vision Labs' source analysis algorithms allows us to provide several additional features to help users understand large amounts of code with less effort. ANTLRWorks 2 allows users to hover over an element in a grammar to see a tooltip with information about the referenced rule.

Interpreting / Testing strings in ANTLRWorks 2

ANTLRWorks 1.5 has an "Interpreter" tab where you could enter strings to test your parser on. So far I haven't been able to find anything equivalent in ANTLRWorks 2. Does it have anything like that, and if so, how is it accessed?
