" PIKA coding style for vim "

" To enable these vim rules for PIKA only, add this command to your vimrc:
" autocmd BufNewFile,BufRead /path/to/pika/*.[ch] source /path/to/pika/devel-docs/c.vim
"
" Do not use `set exrc` which is a security risk for your system since vim may
" be tricked into running shell commands by .vimrc files hidden in malicious
" projects (`set secure` won't protect you since it is not taken into account
" if the files are owned by you).
