_ yarv-3.0

You can get Rite now. もうRubyにパッチを当てなくても良いのか。それは素晴らしい。

ar rcu libruby-static.a array.o ascii.o bignum.o class.o compar.o dir.o (略)  dmyext.o

しょぼーん。というか、

$ grep ruby_in_eval *.c
error.c:int ruby_in_eval;
error.c:    ruby_in_eval = 0;
error.c:    if (ruby_in_eval) {
eval.c:int ruby_in_eval;
parse.c:// static int ruby_in_eval = 1;
parse.c:    compile_for_eval = ruby_in_eval;
yarvcore.c:RUBY_EXTERN int ruby_in_eval;
yarvcore.c:    ruby_in_eval++;
yarvcore.c:    ruby_in_eval--;

なんだから、error.cのruby_in_evalをRUBY_EXTERNで修飾すれば良いのか。と言いながら、今日はここまで。

ちなみに

でも、1行ならやっちまえ。……でけた。
