)abbrev package SPADPRSR SpadParser
++ Author: Gabriel Dos Reis
++ Date Created: October 10, 2006
++ Date Last Updated: November 12, 2007
++ Description: This package provides a simple Spad algebra parser.
++ Related Constructors: Syntax.
++ See Also: Syntax.
SpadParser(): Public == Private where
Public ==> with
parse: String -> List Syntax
++ parse(f) parses the source file f (supposedly containing
++ Spad algebras) and returns a List Syntax. The filename f
++ is supposed to have the proper extension. Note that this
++ function has the side effect of executing any system command
++ contained in the file f, even if it might not be meaningful.
Private ==> add
parse f ==
parseSpadFile(f)$Lisp : List(Syntax)
