Since composed grammars are often ambiguous, grammar composition requires a mechanism for dealing with ambiguity: either ruling it out entirely through the use of delimiters, or by selecting the desired parse tree from the parse forest. In this paper we show that language boxes – a delimiter-based algorithm atop incremental parsing – can be extended in a way that creates a new point in the design space between these two extremes. In essence, we retain the use of delimiters, but introduce an algorithm which provides a default disambiguation scheme that can automatically insert, remove, or resize language boxes – leading to what we call automatic language boxes. The very nature of the problem means that automatic language boxes cannot always match a user’s intention. However, our experimental evaluation shows that it behaves acceptably in 96.9% of tests involving compositions of real-world programming languages.

This program is tentative and subject to change.
