virtual pages

Virtual pages is the best way to create pages without content (front matter only).

It consists of a list of pages with a path and some front matter variables.

  virtual:
    - path: code
      redirect: https://github.com/ArnaudLigny

output

Defines where and in what format(s) content is rendered.

dir

Directory where rendered pages’ files are saved.

output:
  dir: <directory> # `_site` by default

formats

List of output formats, in which of them pages’ content is rendered (e.g. HTML, JSON, XML, RSS, Atom, etc.).

output:
  formats:
    - name: <name>            # name of the format, e.g.: `html` (required)
      mediatype: <media type> # media type (MIME), ie: 'text/html' (optional)
      subpath: <sub path>     # sub path, e.g.: `amp` in `path/amp/index.html` (optional)
      filename: <file name>   # file name, e.g.: `index` in `path/index.html` (optional)
      extension: <extension>  # file extension, e.g.: `html` in `path/index.html` (required)
      exclude: [<variable>]   # don’t apply this format to pages identified by listed variables, e.g.: `[redirect, paginated]` (optional)

Those formats are used by pagetypeformats (see below) and by the output page’s variable.

pagetypeformats

Array of output formats by each page type (homepage, page, section, vocabulary and term).

output:
  pagetypeformats:
    page: [<format>]
    homepage: [<format>]
    section: [<format>]
    vocabulary: [<format>]
    term: [<format>]

Several formats can be defined for the same type of page. For example the section page type can be automatically rendred in HTML and Atom.

Example:

output:
  dir: _site
  formats:
    - name: html
      mediatype: text/html
      filename: index
      extension: html
    - name: atom
      mediatype: application/xml
      filename: atom
      extension: xml
      exclude: [redirect, paginated]
  pagetypeformats:
    page: [html]
    homepage: [html, atom]
    section: [html, atom]
    vocabulary: [html]
    term: [html, atom]

debug

Enables the debug mode, used to display debug information like Twig dump, Twig profiler, SCSS sourcemap, etc.

debug: <true|false>

There is 2 others way to enable the debug mode:

  1. Run a command with the -vvv option
  2. Set the CECIL_DEBUG environment variable to true

When debug is enabled, you can easily dump a variable in your templates using:

{{ dump(variable) }}
# or
{{ d(variable) }} # HTML dump
