get-reader-module in drscheme:language:language<%>

• (send a-drscheme:language:language get-reader-module) -> sexp-representing-a-require-spec or #f

  The result of this method is used when saving or loading files.

  If the result is a sexp, saved files get a prefix inserted at the beginning (the prefix is determined by calling get-metadata). When the file is then loaded, DrScheme recognizes this prefix and sets the language back to match the saved file.

  See also metadata->settings, get-metadata-lines, and get-metadata.
