Ruby學習筆記二協助產生Vim添加代碼頭的代碼_ruby專題

指令碼語言真是太強了。

我的目的是把我的預設代碼頭功能加到Vim裡面。

/*******************************************************************************  COPYRIGHT NOTICE*  Copyright (c) 2014 All rights reserved*  ----Stay Hungry Stay Foolish----**  @author  : Shen*  @name   :*  @file   : G:\My Source Code\DefaultCode.cpp*  @date   : 2014/06/14 02:44*  @algorithm :******************************************************************************///#pragma GCC optimize ("O2")//#pragma comment(linker, "/STACK:1024000000,1024000000")#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行就搞定了字串的處理。簡直爽爆了。

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 endendload("DefaultCode.cpp")

最後人工把頭尾一加，搞定了。
