# Jekyll Archive Generator
**Deprecation notice:** *There is now an official archive plugin, [Jekyll Archives][1]. To avoid confusion and duplication of effort, 0.4.0 is planned to be the final release of Jekyll Archive Generator and you should probably use Jekyll Archives instead.*
This plugin creates a set of archive pages for a Jekyll website.
Oddly, Jekyll doesn't include a date-based archive for posts out of the box. For example, if you have a permalink structure like `blog/2014/01/01/title`, URL hacking won't work because going to `blog/2014` will return 404 Page Not Found.
Jekyll Archive Generator fixes that by generating all the necessary archive pages for each part of your blog URL structure.
## Installation
This plugin is provided as a gem:
```sh
gem install jekyll-itafroma-archive
```
Once the gem is installed, include it in your Jekyll site's configuration:
```yaml
gems: ['jekyll/itafroma/archive']
```
## Configuration
This plugin's configuration is contained within the `archive` key and supports multiple archives:
```yaml
archive:
- path: /blog/:year
layout: archive_blog
title: Blog archive — :year
include:
tags: ['PHP']
exclude:
categories: ['news']
tags: ['drafts']
- path: /blog/:year/:month
layout: archive_blog
title: Blog archive — :month :year
include:
tags: ['PHP']
exclude:
categories: ['news']
tags: ['drafts']
- path: /blog/:year/:month/:day
layout: archive_blog
title: Blog archive — :month :day, :year
include:
tags: ['PHP']
exclude:
categories: ['news']
tags: ['drafts']
```
### Directives
All directives are optional.
#### path
The tokenized path where the archive should be generated. For example, `/blog/:year` will generate a set of archive pages corresponding to post years: `/blog/2010`, `/blog/2011`, and so on. The following tokens are available:
* `year`: four-digit year
* `short_year`: two-digit year
* `month`: month with leading zeros
* `i_month`: month without leading zeros
* `short_month`: three-letter, capitalized month name (e.g. "Jan")
* `long_month`: full, capitalized month name (e.g. "January")
* `day`: day with leading zeros
* `i_day`: day without leading zeros
* `y_day`: day of the year (e.g. 252)
**Default value:** `/`
#### layout
The name of the layout to use for the archive pages. An example layout named `archive.html` is included in this repository. See **Usage** below for more information.
**Default value:** `archive`
#### title
The tokenized title of the archive pages. This uses the same tokens available for the `path` directive above. For example, `Blog archive — :year` will generate archive page titles like *Blog Archive — 2010*, *Blog Archive — 2011*, and so on.
**Default value:** `Blog archive`
#### include
A mapping of front matter keys used to "whitelist" posts for the archive. Each key in the mapping is an array of strings for that specific key to include. This is conjunctive: if a post matches at least one condition, it will be included in the archive.
For example, `categories: ['foo', 'bar']` will ensure that only posts in the `foo` or `bar` categories will be included in the archive.
If `include` is not present, all posts will be included in the archive.
**Default value:** empty (all posts will be included)
#### exclude
A mapping of front matter keys used to exclude posts from the archive. Each key in the sequence is an array of strings for that specific key to exclude.
For example, `categories: ['foo', 'bar']` will exclude any post that has the `foo` or `bar` category.
Exclusion filters are run *after* inclusion criteria specified by the `include` directive.
**Default value:** empty (no posts will be excluded)
## Usage
An example layout named `archive.html` is included in this repository. Two variables are exposed to the archive layout:
### page.archive.posts
The collection of posts for the specific time period in the archive. For example, `page.archive.posts` will only contain posts from May 2014 in the May 2014 archive page.
### page.archive.paginator
A paginator to navigate between archive pages at a specific date "resolution". For example, on the archive page for May 2014, the paginator will let you navigate between months. On the archive page for May 26, 2014, the paginator will let you navigate between days.
This paginator contains many of the same values found in [Jekyll's native paginator][2] (description of variables copied from that page):
* `page.archive.paginator.page`: the current page number
* `page.archive.paginator.total_pages`: the number of pagination pages
* `page.archive.paginator.previous_page`: the page number of the previous pagination page, or `nil` if no previous page exists
* `page.archive.paginator.previous_page_path`: the path of previous pagination page, or `nil` if no previous page exists
* `page.archive.paginator.next_page`: the page number of the next pagination page, or `nil` if no subsequent page exists
* `page.archive.paginator.next_page_path`: the path of next pagination page, or `nil` if no subsequent page exists
