|Covid-19|ASF+SDF Meta Environment Wikipedia
The ASF+SDF Meta-Environment is an IDE and toolset for interactive program analysis and transformation. It combines SDF (Syntax Definition Formalism), ASF (Algebraic Specification Formalism) and other technologies.
Some of the features:Program analysis
Generation of interactive programming environments (IDEs)
Visualization of parse trees
Pretty printer generation
Components:MetaStudio, the IDE
PGEN parse table generator
Scannerless GLR parser (SGLR) for parsing terms over SDF grammars
SGLR parser generator for SDF
ASF, allows term rewriting and automatic generic tree traversals
ATerms for generic data representation
ApiGen, generates strongly typed APIs in C and Java
ToolBus architecture for connecting the various tools
The ToolBus is a component interconnection architecture (somewhat like D-Bus or CORBA) based on a process algebra formalism. ATerms is a generic data representation format that is very efficient in terms of resource usage, due to maximal subterm sharing and automatic garbage collection. It is used throughout most of the tools in the toolset, and APIs are provided in C and Java so developers can use it in their own applications.
