Components

Basics

  • packsdfGT: collect Sdf modules into a single Sdf definition file.
  • unpacksdfGT: split a single Sdf definition file into separate Sdf modules (unpackGT is a non-Sdf-specific variant).
  • sdfppGT, sdf2textGT: pretty-print Sdf syntax definitions.
  • ast2boxGT: a generic pretty-printer.
  • ast2aboxGT: ??
  • parseGT: parse terms over grammars in the GrammarBase?.
  • ppgenGT: generate a pretty-print table for a grammar.
  • ast2aboxGT: transforms an abstract syntax tree to BOX.
  • asfix2aboxGT: transforms a parse tree to BOX.

  • sdf2sdfGT: combine transformations on Sdf syntax definitions

Grammar analysis

  • sdfbenchGT: benchmarking parsers generated from grammars.
  • sdfwfGT: grammar well-formedness checker.
  • tohtmlsdfGT: creating clickable (visual) representations of grammars.
  • importssdfGT: analyze the import structure of a grammar.
  • importsstrategoGT: analyze the import structure of a Stratego specification.
  • getsortgraphGT, sdf2sgGT, sdfdocGT, GraphXML2dot?.

Grammar (re)construction

  • yacc2sdfGT: transform Yacc input into an Sdf definition.
  • happy2yaccGT: transform Happy input into Yacc input.
  • dtd2sdfGT: transform an XML DTD into an Sdf definition.
  • sdfconsGT, rmconsGT: add cons annotations to an Sdf grammar, or remove them.
  • addlabelsGT, rmlabelsGT: add labels to an Sdf grammar, or remove them.
  • asfix2sdfGT: reconstruct an Sdf grammar from a parse tree.
  • sdfnormalizeGT, sdfdenormalizeGT: introduce kernel Sdf productions, or eliminate them.

Tree manipulation

  • asfixyieldGT, also known as asourceGT: unparsing parse trees.
  • implodeasfixGT: transforming parse trees to abstract syntax trees.
  • sdf2asdfGT: generating an AbstractSdf? definition from an Sdf definition.

Libraries

  • asfixGT: library code related to the parse tree formalism AsFix.
  • libGT: miscelaneous library code.

Download

  • XtDownload: The grammar tools are distributed as part of the XT distribution.
