property relativeReference

relativeReference?: boolean;

Allow refer to layouts/partials by relative pathname. To avoid arbitrary filesystem read, paths been referenced also need to be within corresponding root, partials, layouts. Defaults to true.

property renderLimit

renderLimit?: number;

For DoS handling, limit total time (in ms) for each render() call.

property root

root?: string | string[];

A directory or an array of directories from where to resolve layout and include templates, and the filename passed to .renderFile(). If it's an array, the files are looked up in the order they occur in the array. Defaults to ["."]

property strictFilters

strictFilters?: boolean;

Whether or not to assert filter existence. If set to false, undefined filters will be skipped. Otherwise, undefined filters will cause an exception. Defaults to false.

property strictVariables

interface PartialScope

interface PartialScope {}

property isolated

If true, names in scope will be added to a new, isolated scope before analyzing any child templates, without access to the parent template's scope.

property name

name: string;

The name of the partial template. We need this to make sure we only analyze each template once.

property scope

A list of names that will be in scope for the child template.
If an item is a [string, Argument] tuple, the string is considered an alias for the argument.

interface StaticAnalysis

The result of calling analyze() or analyzeSync().

property globals

globals: Variables;

Variables that are not in scope. These could be a "global" variables that are expected to be provided by the application developer, or possible mistakes from the template author.
If a variable is referenced before and after assignment, you should expect that variable to be included in globals, variables and locals, each with a different location.

property locals

locals: Variables;

Template variables that are added to the template local scope using tags like assign, capture or increment.

property variables

variables: Variables;

All variables, whether they are in scope or not. Including references to names such as forloop from the for tag.
