Online Name-Based Navigation for Software Meta-languages

Software language design and implementation often involve specifications written in various esoteric meta-languages. Language workbenches generally include support for precise name-based navigation when browsing language specifications <i>locally</i>, but such support is lacking when browsing the same specifications <i>online</i> in code...

A Constraint Language for Static Semantic Analysis Based on Scope Graphs

In previous work, we introduced scope graphs as a formalism for describing program binding structure and performing name resolution in an AST-independent way. In this paper, we show how to use scope graphs to build static semantic analyzers. We use constraints extracted from the AST to specify facts about binding, typing, and initialization. We...

A Constraint Language for Static Semantic Analysis Based on Scope Graphs with Proofs

In previous work, we introduced scope graphs as a formalism for describing program binding structure and performing name resolution in an AST-independent way. In this paper, we show how to use scope graphs to build static semantic analyzers. We use constraints extracted from the AST to specify facts about binding, typing, and initialization. We...

A Language Designer's Workbench: A One-Stop-Shop for Implementation and Verification of Language Designs

The realization of a language design requires multiple artifacts that redundantly encode the same information. This entails significant effort for language implementors, and often results in late detection of errors in language definitions. In this paper we present a proof-of-concept language designer's workbench that supports generation of IDEs...

Declarative specification of template-based textual editors

Syntax discoverability has been a crucial advantage of structure editors for new users of a language. Despite this advantage, structure editors have not been widely adopted. Nevertheless, the Cheetah system, developed at Capgemini, leverages a structure editor to aid domain experts modeling tax-benefit rules in a domain specific language. The...
