For example, the following program
def foo(k1: 1); end # line 1
foo(k2: 2) # line 2
causes "unknown keyword: k2 (ArgumentError)".
Before this patch, the backtrace location is only line 2.
However, error should be located at line 1 (over line 2 in
stack trace). This patch fix this problem.
* class.c (rb_keyword_error_new): separate exception creation logic
from rb_keyword_error(), to use in vm_args.c.
* vm_insnhelper.c (rb_arg_error_new): rename to rb_arity_error_new().
* vm_args.c (argument_arity_error): rename to argument_arity_error().
* vm_args.c (arugment_kw_error): added to fix backtrace.
* test/ruby/test_keyword.rb: add tests.
