Class SightlyCompiler

java.lang.Object

org.apache.sling.scripting.sightly.compiler.SightlyCompiler

public final class SightlyCompiler
extends java.lang.Object

The SightlyCompiler interprets a HTL script and transforms it internally into a CommandStream. The CommandStream can be fed to a BackendCompiler for transforming the stream into executable code, either by transpiling the commands to a JVM supported language or by directly executing them.

Method Detail

withKnownExpressionOptions

public static SightlyCompiler withKnownExpressionOptions(@NotNull
                                                         @NotNull java.util.Set<java.lang.String> options)

Returns an instance of the SightlyCompiler with the provided options added to the list of known expression options.

The compiler builds internally a set of allowed options from the options permitted by the expressions or plugins. As soon as an expression contains an unknown option the compiler logs a warning. Since the compiler works with dynamically registered RuntimeCalls, some of them can work with additional expression options, not known to the compiler.

NOTE: The data-sly-template, data-sly-call, data-sly-use plugins allow arbitrary options which define parameters and do not generate warnings.

Parameters:

options - the options to add to the compiler's set of known expression options

Returns:

an instance of the compiler

compile

public CompilationResult compile(CompilationUnit compilationUnit)

Compiles a CompilationUnit.

Parameters:

compilationUnit - a compilation unit

Returns:

the compilation result

compile

public CompilationResult compile(CompilationUnit compilationUnit,
                                 BackendCompiler backendCompiler)

Compiles a CompilationUnit, passing the processed CommandStream to the provided BackendCompiler.

Parameters:

compilationUnit - a compilation unit

backendCompiler - the backend compiler

Returns:

the compilation result
