# Patches Jekyll's built-in pagination to work with files *other* than the base index.html.
# Expects the following to be specified in your _config.yml:
#
# paginate_base: "blog" # Puts all pagination folders in the "blog" dir, e.g. "/blog/page2"
# paginate_index: "blog/index.html" # Paginates using the specified file
module Jekyll
class Page
# Added for easier access to a page's path relative to the src directory.
# e.g. "/my-jekyll-site/src/blog/index.html" -> "blog/index.html"
def base_relative_path
File.join(@dir, @name).gsub(/^\//, "")
end
# Added for convenience - implies that perhaps the page.dir method
# is wonky or has content overwritten at some point, but no time to investigate
# right now
def base_relative_dir
@dir.gsub(/^\//,"")
end
end
class Pagination < Generator
# Patched to send "page" rather than "page.name" to the enabler query
def generate(site)
site.pages.dup.each do |page|
paginate(site, page) if Pager.pagination_enabled?(site.config, page) # PATCHED HERE
end
end
# Patched to write pagination output directories into the paginate_base OR root
