Module Meta File

In a module meta file you can define meta information for a Stratego module. The meta file must have the same name as the module, with the .meta extension and is in ATerm^? format. The information in the meta file is targeted at some tool that processes the module. A meta file can contain any meta information for any tool, but an obvious target tool is the Stratego Compiler. The parse-stratego tool uses a Syntax specification in the meta file to determine the syntax that has to be used for parsing the module. This is required for programming with concrete syntax.

For example, to use concrete syntax for XML using the xml-front package, you must instruct the compiler to use the Stratego-xml syntax:

Meta([
  Syntax("Stratego-xml")
])

Meta information

Currently, the following meta information is recognized by parse-stratego:

• Syntax("Language") defines the syntax to be used for parsing this module. The include path should contain a file Language.def or Language.tbl.

• HeuristFilters(Off) or HeuristFilters(On) disables or enables (default) the heuristic filters of SGLR for parsing this module. Disabling these filters is encouraged.
