# Git diff parser

## Install
```
npm install git-diff-parser
```

## Introduction
This is a very simple - and rough - parser for `git diff` and `git format-patch`.

I made this in an hours time as I needed it for another project of mine. No error handling or tests of any sorts implemented yet.

## Usage
Instead of describing the resulting objects I figured an example was self explanatory (right?):
```js
const parser = require("git-diff-parser");
const diff   = parser(require("fs").readFileSync("some.diff"));

// Better viewing of linenumbers
const pad = function(input, toLeft) {
  if (input === null) { input = "-"; }
  if (toLeft === null) { toLeft = false; }
  let result = `${input}`;

while (result.length < 5) {
    result = toLeft ? `${result} ` : ` ${result}`;
  }

return result;
};

// Loop all the commits
diff.commits.forEach(function(commit, idx) {
  if (idx !== 0) {
    console.log("\n\n\n");
  }

if (diff.detailed) {
    console.log(`Commit #${commit.sha} by ${commit.author} <${commit.email}> at ${commit.date}`);
  }

console.log(commit.message);
  console.log("");
  
  commit.files.forEach(function(file, idx) {
    if (idx !== 0) {
      console.log("");
      
      if (file.deleted) { console.log(`[deleted] ${file.name}`); }
      if (file.added) { console.log(`[added] ${file.name}`); }
      if (file.renamed) { console.log(`[renamed] ${file.oldName} -> ${file.name}`); }
      if (!file.added && !file.deleted && !file.renamed) { console.log(`[file] ${file.name}`); }
      
      if (file.binary) {
        console.log("<<< binary >>>");
      } else {
        file.lines.forEach(function(line) {
          if (line.break) { console.log(""); }
          if (line.type === "added") {console.log(`${pad()}/${pad(line.ln1, true)} + ${line.text}`); }
          if (line.type === "deleted") { console.log(`${pad(line.ln1)}/${pad("-", true)} - ${line.text}`); }
          if (line.type === "normal") { console.log(`${pad(line.ln1)}/${pad(line.ln2, true)}   ${line.text}`); }
        });
      }
    }
  });
});
```
