filter_entries(entries, base_directory = nil) click to toggle source

Filter out any files/directories that are hidden or backup files (start with “.” or “#” or end with “~”), or contain site content (start with “_”), or are excluded in the site configuration, unless they are web server files such as ‘.htaccess’.

entries - The Array of String file/directory entries to filter. base_directory - The string representing the optional base directory.

Returns the Array of filtered entries.

# File lib/jekyll/reader.rb, line 141
def filter_entries(entries, base_directory = nil)
  EntryFilter.new(site, base_directory).filter(entries)
end
get_entries(dir, subfolder) click to toggle source

Read the entries from a particular directory for processing

dir - The String representing the relative path of the directory to read. subfolder - The String representing the directory to read.

Returns the list of entries to process

# File lib/jekyll/reader.rb, line 151
def get_entries(dir, subfolder)
  base = site.in_source_dir(dir, subfolder)
  return [] unless File.exist?(base)

  entries = Dir.chdir(base) { filter_entries(Dir["**/*"], base) }
  entries.delete_if { |e| File.directory?(site.in_source_dir(base, e)) }
end
read() click to toggle source

Read Site data from disk and load it into internal data structures.

Returns nothing.

# File lib/jekyll/reader.rb, line 14
def read
  @site.layouts = LayoutReader.new(site).read
  read_directories
  read_included_excludes
  sort_files!
  CollectionReader.new(site).read
  ThemeAssetsReader.new(site).read
  read_data
end
read_data() click to toggle source

Read and merge the data files. If a theme is specified and it contains data, it will be read. Site data will overwrite theme data with the same key using the semantics of Utils.deep_merge_hashes.

Returns nothing.

# File lib/jekyll/reader.rb, line 30
def read_data
  @site.data = DataReader.new(site).read(site.config["data_dir"])
  return unless site.theme&.data_path

  theme_data = DataReader.new(
    site,
    :in_source_dir => site.method(:in_theme_dir)
  ).read(site.theme.data_path)
  @site.data = Jekyll::Utils.deep_merge_hashes(theme_data, @site.data)
end
read_directories(dir = "") click to toggle source

Recursively traverse directories to find pages and static files that will become part of the site according to the rules in filter_entries.

dir - The String relative path of the directory to read. Default: ”.

Returns nothing.

# File lib/jekyll/reader.rb, line 55
def read_directories(dir = "")
  base = site.in_source_dir(dir)

  return unless File.directory?(base)

  dot_dirs = []
  dot_pages = []

  dot = Dir.chdir(base) { filter_entries(Dir.entries("."), base) }
  dot.each do |entry|
    file_path = @site.in_source_dir(base, entry)
    if File.directory?(file_path)
      dot_dirs << entry
    elsif Utils.has_yaml_header?(file_path)
      dot_pages << entry
    else
      dot_static_files << entry
    end
  end

  retrieve_pages(dir, dot_pages)
  retrieve_static_files(dir, dot_static_files)
end
retrieve_dirs(_base, dir, dot_dirs) click to toggle source

Recursively traverse directories with the read_directories function.

base - The String representing the site’s base directory. dir - The String representing the directory to traverse down. dot_dirs - The Array of subdirectories in the dir.

Returns nothing.

# File lib/jekyll/reader.rb, line 102
def retrieve_dirs(_base, dir, dot_dirs)
  dot_dirs.each do |file|
    dir_path = site.in_source_dir(dir, file)
    rel_path = PathManager.join(dir, file)
    @site.reader.read_directories(rel_path) unless @site.dest.chomp("/") == dir_path
  end
end
retrieve_pages(dir, dot_pages) click to toggle source

Retrieve all the pages from the current directory, add them to the site and sort them.

dir - The String representing the directory retrieve the pages from. dot_pages - The Array of pages in the dir.

Returns nothing.

# File lib/jekyll/reader.rb, line 117

  site.pages.concat(PageReader.new(site, dir).read(dot_pages))
end
retrieve_posts(dir) click to toggle source

Retrieves all the posts(posts/drafts) from the given directory and add them to the site and sort them.

dir - The String representing the directory to retrieve the posts from.

Returns nothing.

# File lib/jekyll/reader.rb, line 88
def retrieve_posts(dir)
  return if outside_configured_directory?(dir)

  site.posts.docs.concat(post_reader.read_posts(dir))
  site.posts.docs.concat(post_reader.read_drafts(dir)) if site.show_drafts
end
retrieve_static_files(dir, dot_static_files) click to toggle source

Retrieve all the static files from the current directory, add them to the site and sort them.

dir - The directory retrieve the static files from. dot_static_files - The static files in the dir.

Returns nothing.

Internal

Determine if the directory is supposed to contain posts and drafts. If the user has defined a custom collections_dir, then attempt to read posts and drafts only from within that directory.

Returns true if a custom collections_dir has been set but current directory lies outside that directory.

# File lib/jekyll/reader.rb, line 169
def outside_configured_directory?(dir)
  collections_dir = site.config["collections_dir"]
  !collections_dir.empty? && !dir.start_with?("/#{collections_dir}")
end
