Reference Card

The data-flow diagram below shows the main tools from the StrategoXT and SDF2 packages. The red edges indicate the standard composition of a transformation system consisting of a parser, a transformation component (trafo), and a pretty-printer for programs in language Lang. The blue edges show the generation of components for this transformation system. The black edges show other tools.

Composition of a transformation system using files

• sglri -p Lang.tbl -i file.lang -o file.ast
• trafo -i file.ast -o file-trafo.ast
• ast2text -p Lang.pp -i file-trafo.ast -o file-trafo.lang

using pipes

• sglri -p Lang.tbl -i file.lang | trafo | ast2text -p Lang.pp -o file-trafo.lang
