设置vim折叠

  首先是按安装vim-full,alias vi='vim',syntax on!!!!再编辑/etc/vimrc,
添加set foldmethod=syntax

代码折叠
许多editor都支持代码折叠，Vim也不例外
常用的快捷键
zc 折叠代码
zo 打开折叠的代码
还有其他的快捷键可以查看帮助
:h fold

 unsigned char *tmp;

 33 struct icmp *icmp_hdr_make(unsigned char *buf,int icmp_type,unsigned int

 zo之后的代码:
 33 struct icmp *icmp_hdr_make(unsigned char *buf,int icmp_type,unsigned int
 34                            icmp_code,struct ip_header_fields *header) {
 35
 36         struct icmp *icmp_pt = (struct icmp *)(buf+sizeof(struct ip));
 37
 38         icmp_pt->icmp_type = icmp_type;
 39
 40 +--- 24 lines: switch(icmp_type) {----------------------------------------------------------------------------
 64
 65 +---  4 lines: if (!header->error) {--------------------------------------------------------------------------
 69  
 70         if (icmp_type == ICMP_TIMESTAMP)
 71                 icmp_pt->icmp_otime = orig_timestamp();
