Ruby学习笔记二帮助生成Vim添加代码头的代码

脚本语言真是太强了。

我的目的是把我的默认代码头功能加到vim里面。

#include <bits/stdc++.h>
#include <cmath>
#include <cstdio>
#include <string>
#include <cstring>
#include <iomanip>
#include <iostream>
#include <algorithm>
using namespace std;
template<class t>inline bool updatemin(t& a, t b){ return a > b ? a = b, 1: 0; }
template<class t>inline bool updatemax(t& a, t b){ return a < b ? a = b, 1: 0; }

/*//stl
#include <map>
#include <vector>
#include <list>
#include <stack>
#include <deque>
#include <queue>
*/

/*//computational geometry
#include <complex>
#define x real()
#define y imag()
typedef complex<double> point;
*/

typedef long long int64;

void solve()
{

}

int main()
{

 return 0;
}

用ruby10行就搞定了字符串的处理。简直爽爆了。

def load( path )
 file.foreach(path) do |line|
  line["\n"] = ""
  str = "let l = l + 1 | call setline(l, \'#{line}\')"
  file.open("s.txt", "a") do |f|
   f << "#{str}\n"
  end
 end
end

load("defaultcode.cpp")

最后人工把头尾一加，搞定了。
