Method Detail

define

public Declaration define(Symbol name,
                          TemplateScope templateScope,
                          ScopeExp scope,
                          Translator comp)

parsePatternNext

public java.lang.Object parsePatternNext(Pair patList,
                                         Translator comp)

parsePatternCar

public java.lang.Object[] parsePatternCar(Pair patList,
                                          int scanNesting,
                                          ScopeExp scope,
                                          Translator comp)

Parse a declaration or more generally a pattern. The actual pattern is an initial sublist (using just the initial car) of the patList.

Returns:

A 2-element array, where element 0 is the unused remainder of patList, while element 1 is a Declaration for that pattern.

parsePatternCar

public java.lang.Object[] parsePatternCar(Pair patList,
                                          Expression init,
                                          TemplateScope templateScope,
                                          int scanNesting,
                                          ScopeExp scope,
                                          Translator comp)

parseBracketListPattern

public void parseBracketListPattern(Pair patpair,
                                    int scanNesting,
                                    ScopeExp scope,
                                    Declaration decl,
                                    Translator comp)

Handle patterns of the form [pat1 ... patN].

setInitializer

public static void setInitializer(Declaration decl,
                                  Expression init,
                                  ScopeExp scope,
                                  Translator comp)

literalPattern

public QuoteExp literalPattern(java.lang.Object patval,
                               Translator comp)

compareLiteral

public Expression compareLiteral(Declaration param,
                                 QuoteExp literal)
