* * eval.c (eval_init): Registered hash_update_1 as intrinsic.Kaz Kylheku2014-02-141-1/+25
| | | | | | | | * hash.c (hash_update_1): New function. * hash.h (hash_update_1): Declared. * txr.1: Documented hash-update-1.
* Different approach: optional arguments on hash-isec and hash-uni allowKaz Kylheku2014-02-141-18/+12
| | | | | | | | | | | | | | | | | | | | | for more flexible joining of data from the hash tables. * eval.c (eval_init): Remove hash_guni and hash_gisec. Change registration for hash_uni and hash_isec to three arguments with one optional. * hash.c (hash_uni): Third parameter introduced, join_func. The default behavior changes: in the two argument case, clashing keys prefer the value from hash1 rather than hash2. For this reason, we now iterate over hash2 first, then hash1. (hash_guni): Removed. (hash_isec): Third parameter introduced, join_func. (hash_gisec): Removed. * hash.h (hash_uni, hash_isec): Declarations updated. (hash_guni, hash_gisec): Delarations removed. * txr.1: Documentation updated.
* * eval.c (eval_init): Register hash_guni and hash_gisec as intrinsics.Kaz Kylheku2014-02-141-5/+18
| | | | | | | | | | | * hash.c (hash_guni, hash_gisec): New functions. (hash_isec): Bugfix: since gethash was naively used, keys in hash2 associated with the value nil were erroneously omitted from the intersection. * hash.h (hash_guni, hash_gisec): Declared. * txr.1: Documented new functions.

| | | | | | | | | | | | | static functions. (comb): Support hash tables. * hash.c (print_key_val): When values are nil, print in a more condensed way by omitting the second element. This notation is accepted as input already by the parser. (hash_insert_pair): New function. * txr.1: Description of comb updated to indicate that it works over hashes.
* Relaxed behavior: don't throw errors for impossible permutations,Kaz Kylheku2014-02-101-29/+37

We now make a blank environment upfront and extend it destructively with env_vbind. Except that after evaluating an init form, we create a new environment: this is in case a lexical closure was made by the init form, in which event we don't want to be destructively manipulating the environment any more. * txr.1: Clarified.
