Module Meta File
Stratego -- Strategies for Program Transformation
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.
