From af9b0da125871c6bfbc3b7893d199a79420e5833 Mon Sep 17 00:00:00 2001 From: mame Date: Sat, 4 Nov 2017 14:24:16 +0000 Subject: Avoid usage of the magic number `(NODE*)-1` This magic number has two meanings depending upon the context: * "required keyword argument (no name)" on NODE_LASGN (`def foo(x:)`) * "rest argument (no name)" on NODE_MASGN and NODE_POSTARG ('a, b, * = ary` or `a, b, *, z = ary`) To show this intention explicitly, two macros are introduced: NODE_SPECIAL_REQUIRED_KEYWORD and NODE_SPECIAL_NO_NAME_REST. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60650 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- node.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'node.h') diff --git a/node.h b/node.h index 848ef1b76e..d85f86746a 100644 --- a/node.h +++ b/node.h @@ -445,6 +445,9 @@ typedef struct RNode { #define NEW_ATTRASGN(r,m,a) NEW_NODE(NODE_ATTRASGN,r,m,a) #define NEW_PRELUDE(p,b,o) NEW_NODE(NODE_PRELUDE,p,b,o) +#define NODE_SPECIAL_REQUIRED_KEYWORD ((NODE *)-1) +#define NODE_SPECIAL_NO_NAME_REST ((NODE *)-1) + RUBY_SYMBOL_EXPORT_BEGIN typedef struct node_buffer_struct node_buffer_t; -- cgit v1.2.3
