# Following renames in gitlog

This demo serves as a minimal working example for the blog post

<https://peterbabic.dev/blog/following-renames-in-gitlog>

The method outlined here is curently used in my blog to determine when the
markdown blog post file was published and also when it was last edited.

## Setup

```bash
git clone https://git.peterbabic.dev/demo/following-renames-gitlog.git
cd following-renames-gitlog
npm install
npm run dev
```

This should produce the following output:

```js
{
  status: [ 'M' ],
  files: [ 'renamed-blog-post.md' ],
  subject: 'add additional sentence to to blog post',
  authorName: 'Peter Babič',
  authorDate: '2020-12-03 22:07:31 +0100'
}
{
  status: [ 'M' ],
  files: [ 'renamed-blog-post.md' ],
  subject: 'insert a chapter into post',
  authorName: 'Peter Babič',
  authorDate: '2020-12-03 21:51:19 +0100'
}
{
  status: [ 'R100', 'D' ],
  files: [ 'renamed-blog-post.md', 'blog-post.md' ],
  subject: 'rename blog post',
  authorName: 'Peter Babič',
  authorDate: '2020-12-03 21:49:27 +0100'
}
{
  status: [ 'A' ],
  files: [ 'blog-post.md' ],
  subject: 'insert blog post file to track',
  authorName: 'Peter Babič',
  authorDate: '2020-12-03 20:54:27 +0100'
}
```

Which is equivalent to the command

```bash
git log --follow --name-status renamed-blog-post.md
```

Producing the output

```

With the difference that the former is already parsed and ready to use in a
script.
