1. 在官网下载最新版Lua源码
2. 解压后进入目录,找到/src/llex.c,打开修改
找到如下内容
修改为下面代码,并保存。
default: {
if (lislalpha(ls->current)|| ls->current >= 0x80) { /* identifier or reserved word? *///修改
TString *ts;
do {
if (ls->current >= 0x80) { //修改
save_and_next(ls); //修改
if(ls->current !='('&&ls->current >=0x80)//修改
save_and_next(ls); //修改
}
else if(ls->current !='('){ //修改
save_and_next(ls); //修改
}
} while (lislalnum(ls->current)|| ls->current >= 0x80);//修改
ts = luaX_newstring(ls, luaZ_buffer(ls->buff),
luaZ_bufflen(ls->buff));
seminfo->ts = ts;
if (isreserved(ts)) /* reserved word? */
return ts->extra - 1 + FIRST_RESERVED;
else {
return TK_NAME;
}
}
else { /* single-char tokens (+ - / ...) */
int c = ls->current;
next(ls);
return c;
}
}
3. 编译
- Mac OS X 系统
cd lua-5.3.4 #进入lua目录
make macosx test
make install
- Linux 系统
cd lua-5.3.4
make linux test
make install
- Win 系统可以用vs编译。
ps.这样修改也支持中文函数名,网上修改的方法 function 跑()
运行会报错如下:
lua: 任务.lua:18: '(' expected near ')'
