Settings let you define global metadata that can be accessed from the execution context or documents.

At execution time all settings are combined into a single set of metadata accessible via the execution context, which implements IMetadata for the purpose of exposing settings values.

Settings that you can use to control Statiq Framework include:

  • Host: The host to use when generating links (for example, "statiq.dev").
  • LinksUseHttps: Indicates if generated links should use HTTPS instead of HTTP as the scheme.
  • LinkRoot: The default relative root path to use when generating links (for example "/virtual/directory").
  • LinkHideIndexPages: Indicates whether to hide index pages by default when generating links.
  • LinkHideExtensions: Indicates whether to hide ".html" and ".htm" extensions by default when generating links.
  • LinkLowercase: Indicates that links should always be rendered in lowercase.
  • UseStringContentFiles: This will cause temporary backing files to be created for string document content instead of storing that content in memory.
  • UseCache: Indicates whether caching should be used.
  • CleanOutputPath: Indicates whether to clean the output path on each execution.
  • DateTimeInputCulture: Indicates the culture to use for reading and interpreting dates as input.
  • DateTimeDisplayCulture: Indicates the culture to use for displaying dates in output.

Settings keys are just strings, but most built-in settings are also defined as string constants in the Keys class.

As with any other metadata, setting values can be computed values or configuration delegates and their value will be evaluated at run-time.

Cascade To Documents

All settings cascade to documents (credit to 11ty for the excellent term). That means that any value defined in configuration files, environment variables, etc. is also available as document metadata unless otherwise overwritten by the document. This include settings that would conventionally be set just at a document level (for example, a page title). This feature can be very useful for situations when you want all documents to have a particular default value for a setting or when you want to use a common computed value to define a script to use to calculate a different value for each document.

For example, if you want to set the "Published" key of every document to the date the site was built you can add this to your appsettings.json file:

{
    "Published": "=> DateTime.Today"
}

Note that the setting demonstrated above uses a computed value to calculate the current DateTime at runtime.

Specifying Settings With The Bootstrapper

Settings can be provided directly to the engine, but the easiest and most common way to specify settings is to use a bootstrapper.

Configuration Files

As with many other .NET Core applications, Statiq supports the use of configuiration files with one of the following names:

  • appsettings.json
  • statiq.json

Support for both is provisioned by the bootstrapper by default.

Environment Variables

The bootstrapper adds all existing environment variables as settings by default. This makes it easy to define settings for your generation from build servers.

Fluent API

The bootstrapper also contains fluent methods for specifying settings.
