| * | New macros: each-true, some-true, each-false, some-false. | Kaz Kylheku | 2022-01-12 | 1 | -10/+40 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisplib.c (arith_each_set_entries): Trigger autoload on new symbols. * stdilb/arith-each.tl (sys:arith-each): Generalize macro to handle short-circuiting logical operations. The op-iv parameter, which is a cons, is spread into two op and iv parameter. One new argument appears, short-circ. This specifies a code for short-circuiting behavior: t means iteration continues while the result is true; nil means it continues while it is nil, and + means iteration continues while the accumulator is nonzero. A new convention is in effect: the operator has to be specified as a list in order to request accumulating behavior, e.g (+) or (*). Otherwise the operator specifies a predicate that is applied to the forms, without taking into account the prior value. (sum-each, sum-each*, mul-each, mul-each*): Spread the op-iv arguments. Wrap the op argument in a list to request accumulation. In the case of mul-each and mul-each*, specify + for the short-circ argument, which means that iteration stops when the accumulator becomes zerop. sum-each and sum-each* specify : for the short-circ argument which is unrecognized, and so ther is no short-circuiting behavior. (each-true, some-true, each-false, some-false): New macros. * tests/016/arith.tl: New tests. * txr.1: Documented new macros and added note about possible short-circuiting in mul-each and mul-each*. * stdlib/doc-syms.tl: Updated. | ||||
| * | sum-each, mul-each: handle no vars case. | Kaz Kylheku | 2022-01-11 | 1 | -9/+13 |
| | | | | | | | | | | | | | | | | * stdlib/arith-each.tl (sys:arith-each): If there are no vars, then just reduce to the identity element value. This is alreading happening fine for the each-prod family of operators. * tests/016/arith.tl: Test cases covering the no vars and empty iteration identity element cases for sum-each and mul-each, as well as the *-prod variants. * txr.1: Document empty iteration and empty vars behavior for arithmetic each operators as well as the each-prod family. | ||||

| * | product/arithmetic each: missing block nil. | Kaz Kylheku | 2021-12-20 | 1 | -24/+39 |
| | | | | | | | | | | | | | | | | | | | | * stdlib/arith-each.tl (sys:vars-check): New function, copy and pasted from each-prod.tl. (sys:arith-each): New macro. (sum-each, sum-each*, mul-each, mul-each*): Reworked using sys:arith-each macro. This macro uses logic borrowed from a stripped-down expand-each in the compiler. * stdlib/each-prod.tl (sys:expand-each-prod, sys:expand-arith-each-prod*): Add the block nil around the mapping call, taking care that the initialization forms are evaluated outside of the block, and their values bound to gensyms that then form the function arguments. * txr.1: Document the missing requirements for all the affected macros that there must be an anonymous block around the body, which, if used, determines the return value. | ||||
| * | New variants of each operator for sum and product. | Kaz Kylheku | 2021-09-23 | 1 | -0/+54 |
| * lisplib.c (arith_each_instantiate, arith_each_set_entries): New functions. (each_prod_set_entries): Add sum-each-prod, sum-each-prod*, mul-each-prod and mul-each-prod* as autoload triggers for each-prod.tl, where those macros are now defined. (lisplib_init): Register autoloading of arith-each.tl via the two new functions. * stdlib/arith-each.tl: New file. * stdlib/each-prod.tl (sys:expand-each-prod*): Handle sum-each-prod* and mul-each-prod* in the same way, by mapping to their parallel binding counterparts. (sys:expand-arith-each-prod): New function. (sym-each-prod, mul-each-prod, sum-each-prod*, mul-each-prod*): New macros. * tests/016/arith.tl: New tests. * txr.1: Documented. * stdlib/doc-syms.tl: Updated. | |||||
