Instance Method Details

#dependencies ⇒ Object

:call-seq:

Returns a list of dependencies (resource files, the template file, etc). Useful when creating a Rake task based on this template.

# File 'lib/docter/collection.rb', line 286

def dependencies #:nodoc:
  files = @sources.map { |path| File.directory?(path) ? FileList[path, File.join(path, '**/*')] : path }.flatten +
    (@toc_resource ? [@toc_resource.filename] : [])
end

#exclude(*paths) ⇒ Object

:call-seq:

exclude(*paths) => self

Excludes files or directories from the collection.

def exclude(*paths)
  @sources.exclude *paths.flatten
  self
end

#file(path) ⇒ Object

:call-seq:

file(path) => filename

Returns the full path based on the relative path. For example:

collection.include('pages', 'LICENSE')
collection.find('index.textile') => 'pages/index.textile'
collection.find('LICENSE') => 'LICENSE'

  @sources.inject(nil) do |found, file|
    break found if found

      base = file + '/'
      FileList[File.join(file, '**/*')].find { |file| file.sub(base, '') == path }
    else
      file if File.basename(file) == path

#generate(template, to_dir, *args) ⇒ Object

:call-seq:

generate(template, to_dir, :all?)
generate(template, to_dir, pages)
generate(template, to_dir, page)
generate(template, to_dir, :one_page)

The first form generates all pages from the ToC into the destination directory. The :all argument is optional. In addition, it copies all other resource files to the destination directory.

The second form works the same way but only for the specified pages, and the third form for a single page. Neither copies any resource files.

The fourth form generates a single HTML document in the destination directory (index.html) with all pages from the ToC, and copies all resource files to the destination directory. It will typically use a different template than the first three forms.

#render(template, *args) ⇒ Object

:call-seq:

render(template, page, options?) => html
render(template, options?) => html

Render page or collection using the template.

The first form attempts to reload the page if modified and passes the page to the template context, returning a single HTML document generated from that page.

The second form attempts to reload all modified pages from the ToC, and passes all these pages to the template context, returning a single HTML document generates from pages as ordered by the ToC.
