將.patch轉換爲HTML格式輸出，以便在線觀看

因此，我有一個工具，用戶可以將用戶上傳SVN .patch文件。與其單獨下載和查看它，我希望能夠通過紅色的綠色設計直接在線觀看。將.patch轉換爲HTML格式輸出，以便在線觀看

你的問題是什麼？ – scragar 2014-09-02 12:22:59

@scragar如何做到這一點？以補丁文件作爲輸入和輸出HTML – 2014-09-02 13:00:16

你可以試試沿線的東西：

<?php 

$file = __DIR__ . '/foo.patch'; 

echo '<doctype html> 
<html> 
<head> 
<style> 
.header { 
    color: black; 
} 
.header-comment { 
    color: grey; 
} 
.file-input, .file-change { 
    color: green; 
} 
.file-output { 
    color: blue; 
} 
.file-line-nos { 
    color: blue; 
} 
.line-context { 
    color: darkgrey; 
} 
.line-add { 
    color: green; 
} 
.line-change { 
    color: yellow; 
} 
.line-del { 
    color: red; 
} 
</style> 
</head> 
<body> 
';
