*	printer: [] shouldn't print as [. nil].	Kaz Kylheku	2023-03-23	1	-1/+7
\| \| \| \| \| \| \| \| \| \|	* lib.c (obj_print_impl): In the case when dwim has no args, and the logic short circuits to a closing brace, bypassing the loop, we should only use the dot notation if the terminating atom is other than nil. * tests/012/readprint.tl: Tests added.
*	syntax: read and print [. x] and [. @x].	Kaz Kylheku	2022-09-08	1	-0/+7
	* lib.c (obj_print_impl): Handle (dwim . atom) syntax by printing [. atom]. Note that (dwim . @var) and (dwim . @(expr)) already print as [. @var] and [. @(expr)]; this is not new. But none of these forms are supported by reading without the accompanying change to the parser. * parser.y (dwim): Handle the [. expr] and [ . expr] syntax, so that forms like [. a] and [. @a] have print-read consistency. The motivation is to be able to [. @args] in pattern matching to match a DWIM forms; I tried that and was surprised to have it blow up in my face. * tests/012/readprint.tl: New test file. Future printer/parser changes will be tested here. Historically, changes to the syntax have not been consistently unit-tested. * y.tab.c.shipped: Regenerated.
