How to enable reading line like "# vim: ft=dosini cms=#%s" in VIM?

Question

vim

Actually a question in a subject. I understand that the question is simple, but I can not formulate it in such a way that the search engine would give me the right answer. What needs to be included in VIM so that it defines this directive?

Answer 1

Modeline magic

set modeline
set modelines=5

Безопасная альтернатива против такого:

/* vim:set foldmethod=expr: */
/* vim:set foldexpr=confirm(libcall("/lib/libc.so.6","system","/bin/ls"),"ms_sux"): */
