Meta Data
Introduction
Meta data goes at the top of documents, and is defined by any character that repeats 3 or more times. For example, --- is the most common usage, but you can also use ### or whatever repeats 3 or more times. By default, we parse the meta data with YAML but you can also use CSON by doing --- cson instead.
An example document that uses meta data will look like this:
---
title: "Example Document"
layout: "default"
---
​
My example document content
Special Meta Data
For Files & Documents
title
The title for the document. Useful for headings.
layout
Tells DocPad what layout to use from the layouts folder. Layout files can use other layouts for advanced layout nesting.
There is no default value. Layouts may have a layout called "default", but that is just a naming choice, rather than an implicit default.
name
Defaults to the filename. The name of the document. Useful for listings.
date
Defaults to mtime. Useful for setting a custom date via your documents meta data.
slug
Defaults to a slugified version of the relativeBase. Appears deprecated in favour of url.
url
The URL that you would like to use as the primary URL for the document. When a user accesses a document via a secondary URL, the user will be redirected to the primary URL automatically.
urls
The secondary URLs for a document. It can be a comma separated values list, or an array of values.
ignored
Defaults to false. If set to true, the document will not be parsed. Useful for draft documents.
standalone
Defaults to false. If set to true, when a change is detected for the document, we will only regenerate this document and not anything else (e.g., documents with referencesOthers set to true).
For Documents
referencesOthers
Defaults to false. If set to true, this document will be regenerated when a change occurs in another document. It is automatically set to truewhenever a template helper is called that references another document. This makes so for instance on a blog listing page, when a blog post is changed, we will also regenerate the listing as well as the blog post.
tags
Defaults to []. Tags can be a comma separated values list, or an array of values. While DocPad doesn't use tags for anything specifically, it is nice to have it handled uniformly across websites without you having to do it yourself.
dynamic
Defaults to false. If set to true, the document will be re-rendered on each request. This also adds the req object to the template data.
Special Attributes
For Files & Documents
id
The unique document identifier. Defaults to the cid. When we get the relativePath, we set the id to that instead.
basename
The file's name without the extension.
extension
The file's last extension (e.g., will be set to eco for the file hello.md.eco).
outExtension
The extension used for the output file. Same method as extension however it takes layouts into account as well.
extensions
The file's extensions as an array (e.g., will be set to ["md","eco"] for the file hello.md.eco).
filename
The file's name with the extension.
path
The full path of our source file.
outPath
The full path of our output file.
dirPath
The full directory path of our source file.
outDirPath
The full directory path of our output file.
outFilename
The file's name with the output extension.
relativePath
The relative path of our source file.
relativeOutPath
The relative path of our output file.
relativeDirPath
The relative directory path of our source file.
relativeOutDirPath
The relative directory path of our output file.
relativeBase
The relative path of our source file without the file's extension.
contentType
The MIME content-type for the source file.
outContentType
The MIME content-type for the output file.
ctime
The Date object for when this file was created.
mtime
The Date object for when this file was modified.
encoding
The encoding of the file. Either binary or utf8.
source
When encoding isn't binary, this is set to the raw contents of the file, stored as a string.
content
When encoding isn't binary, this is set to the contents of the file, stored as a string. This is used internally during the rendering process, end-users should never use this property, instead they should either source or contentRendered depending on the use case.
For Documents
write
Defaults to true. Whether or not this document should be written to the output directory.
render
Defaults to true. Whether or not this document should be rendered.
header
The file meta data (header) in String format before it has been parsed.
parser
Defaults to yaml. The parser we used to parse the document's meta data header.
body
The file content (without the meta data header) before we've rendered it.
rendered
Defaults to false. Set to true once we have been rendered.
contentRendered
The rendered content (after is has been wrapped in the layouts).
contentRenderedWithoutLayouts
The rendered content (before being wrapped by the layouts).
