 kawa.lang.Syntax
kawa.lang.Quote
All known Subclasses: kawa.standard.syntax,
| Quote | | public class Quote extends Syntax (Code) | | The Syntax transformer that re-writes the "quote" "quasiquote" primitive.
In both cases recursively resolves SyntaxForm wrappers and resolves
namespaces of symbols. In the case of quasiquote also handles unquoting.

|
| Method Summary | |
| public static Object | append$V(Object[] args)
Same as regular append, but handle SyntaxForm wrappers. | | protected Expression | coerceExpression(Object val, Translator tr)
| | public static Object | consX$V(Object[] args)
A wrapper around LList.consX to make it a "variable-arg method". | | protected Object | expand(Object template, int depth, Translator tr)
| | Object | expand(Object template, int depth, SyntaxForm syntax, Object seen, Translator tr)
Backquote-expand a template. | | protected boolean | expandColonForms()
| | Object | expand_pair(Pair list, int depth, SyntaxForm syntax, Object seen, Translator tr)
| | protected Expression | leaf(Object val, Translator tr)
| | public static Object | quote(Object obj, Translator tr)
Quote an object (without namespace-expansion).
Basically just recursively removes SyntaxForm wrappers. | | public static Object | quote(Object obj)
Quote an object (without namespace-expansion).
Basically just recursively removes SyntaxForm wrappers. | | public Expression | rewrite(Object obj, Translator tr)
|
| QUOTE_DEPTH | | final protected static int QUOTE_DEPTH(Code) | | An initial value for 'depth' for plain (non-quasi) quote.
|
| isQuasi | | protected boolean isQuasi(Code) | | True for quasiquote; false for plain quote.
|
| append$V | | public static Object append$V(Object[] args)(Code) | | Same as regular append, but handle SyntaxForm wrappers.
|
| consX$V | | public static Object consX$V(Object[] args)(Code) | | A wrapper around LList.consX to make it a "variable-arg method".
|
| expand | | Object expand(Object template, int depth, SyntaxForm syntax, Object seen, Translator tr)(Code) | | Backquote-expand a template.
Parameters:
template - the quasiquoted template to expand
Parameters:
depth - - the (net) number of quasiquotes we are inside.The value QUOTE_DEPTH is a special case when we're insidea quote rather than a quasiquote.
Parameters:
tr - the rewrite context the expanded Expression (the result can be a non-expression,in which case it is implicitly a QuoteExp). |
| expandColonForms | | protected boolean expandColonForms()(Code) | | |
| quote | | public static Object quote(Object obj, Translator tr)(Code) | | Quote an object (without namespace-expansion).
