The "hack" to virtually parenthesize ? EXPR : made this unnecessary. The expression is effectively a?(b?(c):d):e and thus b?c:d is evaluated before continuing with the second : function old new delta evaluate_string 1148 1132 -16 Signed-off-by: Denys Vlasenko

shell/math: fix parsing of ?: and explain why it's parsed that way

2023-06-15T08:14:43+00:00

This fixes arith-precedence1.tests. This breaks arith-ternary2.tests again (we now evaluate variables on not-taken branches). We need a better logic here anyway: not only bare variables should not evaluate when not-taken: 1 ? eval_me : do_not_eval but any (arbitrarily complex) expressions shouldn't evaluate as well! 1 ? var_is_set=1 : ((var_is_not_set=2,var2*=4)) function old new delta evaluate_string 1097 1148 +51 Signed-off-by: Denys Vlasenko
