We cannot use the same symbol for the + literal form from the parser, and for the expanded form, + because this creates a confusion when there are multiple + nestings of quasiquote expansion. + + * eval.c (vector_lit_s, vector_list_s, hash_lit_s): New symbol + variables. + (hash_construct_s): Relocated here from hash.c. + (expand_qquote): Part of bugfix: look for hash_lit_s + instead of has_construct_s. Translate to a hash_construct_s + form which is no longer recognizes as a hash literal. + Implementing recognition of a quasiquote vector literal, + handled similarly. + (eval_init): Initialize vector_lit_s, vector_list_s, + hash_list_s and hash_lit_s. + Use vector_list_s when registering vector_list function. + + * eval.h (vector_lit_s, vector_list_s, hash_lit_s, + hash_constuct_s): Declared. + + * hash.c (hash_construct_s): Variable removed + and relocated into eval.c. + (hash_init): Initialization of hash_construct_s removed. + + * hash.h (hash_construct_s): Declaration removed. + + * parser.y: (vector): Action updated to generate + a (vec-lit ...) form if the object contains unquotes, + otherwise generate a vector object. + (hash): Generate hash-lit form, not a + hash-construct form. + +2012-03-14 Kaz Kylheku <kaz@kylheku.com> + Allow quasi-quoting over hash table literals, to express dynamic hash table construction |
