allow-abstract-classes

Determines if the abstract modifier may be used with classes. For more details, see Abstract Classes in ActionScript.

-allow-abstract-classes

allow-import-aliases

Determines if alias syntax for for imported symbols is allowed or not.

-allow-import-aliases

allow-private-constructors

Determines if the private namespace may be used with class constructors. For more details, see Private Constructors in ActionScript.

-allow-private-constructors

closure-lib

Sets the path to a custom distribution of Google’s Closure library, instead of the default version used by the compiler.

-closure-lib path/to/closure

js-define

Defines a global constant at compile time. May be a boolean, number, string, or expression.

-define CONFIG::debugging true -js-define CONFIG::release false

For boolean and numeric values, you may pass in literals like true, false, or 123. Format string values with nested quotes, like “‘hello’”, because the compiler will attempt to evaluate an expression when it encounters a quotation mark.

Maven configuration:

<defines>
    <property>
        <name>BUILD::buildNumber</name>
        <value>'"${buildTimestamp}"'</value>
    </property>
    <property>
        <name>BUILD::buildVersion</name>
        <value>'"${project.version}"'</value>
    </property>
</defines>

Then in AS3 you can do:

// Build Number
private static var _buildNumber:String = BUILD::buildNumber;

// Project Version
private static var _projectVersion:String = BUILD::buildVersion;

html-output-filename

-html-template ./path/to/template.html

Maven configuration:

<htmlTemplate>${basedir}/target/javascript/bin/js-debug/jewel-example-index-template.html</htmlTemplate>

inline-constants

Determines if primitive constant values (such as numbers, booleans, and strings) will be inlined.

-inline-constants

Maven configuration:

<additionalCompilerOptions>-inline-constants=true;</additionalCompilerOptions>

js-compiler-option

Specifies one or more custom compiler options to pass to the Google Closure Compiler, which is used to create the release build of an Apache Royale application.

-js-compiler-option+="--variable_map_output_file gccvars.txt" -js-compiler-option+="--compilation_level SIMPLE_OPTIMIZATIONS"

js-default-initializers

Defaults to true. Enables or disables initialization of primitive (Number, Boolean, etc.) variables with default values in the generated JavaScript. Corresponds to AVM runtime implicit type intialization values.

Note that some reflection utility functions require this to be set to true in order for them to work correctly in JavaScript.

-js-default-initializers

Maven configuration:

<additionalCompilerOptions>-js-default-initializers=true;</additionalCompilerOptions>

js-define

Defines a global constant at compile time for the JavaScript output, but not the SWF output. May be a boolean, number, string, or expression.

-js-define CONFIG::debugging true -js-define CONFIG::release false

For boolean and numeric values, you may pass in literals like true, false, or 123. Format string values with nested quotes, like “‘hello’”, because the compiler will attempt to evaluate an expression when it encounters a quotation mark.

Maven configuration:

<defines>
    <property>
        <name>BUILD::buildNumber</name>
        <value>'"${buildTimestamp}"'</value>
    </property>
    <property>
        <name>BUILD::buildVersion</name>
        <value>'"${project.version}"'</value>
    </property>
</defines>

Then in AS3 you can do:

// Build Number
private static var _buildNumber:String = BUILD::buildNumber;

// Project Version
private static var _projectVersion:String = BUILD::buildVersion;

js-dynamic-access-unknown-members

If the definition of a member cannot be resolved at compile time, emit dynamic access instead of normal member access. Ensures that dynamic members aren’t renamed.

-js-dynamic-access-unknown-members 

Maven configuration:

<additionalCompilerOptions>-js-dynamic-access-unknown-members=true;</additionalCompilerOptions>

js-load-config

Specifies the locations of XML configuration files that define extra compiler options for JavaScript output.

Maven configuration:

js-output

The path where the generated JavaScript output should be saved, if your are also using it for the .swf output path.

-js-output path/to/output

Maven configuration:

Use instead outputDirectory in configuration xml node

prevent-rename-internal-instance-variables

In a release build, determines if instance (non-static) variables in the internal namespace may be renamed or not. The default value is true. This option will be ignored if the prevent-rename-internal-symbols compiler option is false.

-prevent-rename-internal-instance-variables=false

Note: This option applies only to compiling applications using mxmlc. If you are compiling a library (using compc), this option does not exist, and you will get a warning if you try to use it.

Maven configuration:

<additionalCompilerOptions>-prevent-rename-internal-instance-variables=false;</additionalCompilerOptions>

prevent-rename-internal-static-accessors

In a release build, determines if static accessors (getters and setters) in the internal namespace may be renamed or not. The default value is true. This option will be ignored if the prevent-rename-internal-symbols compiler option is false.

-prevent-rename-internal-static-accessors=false

Note: This option applies only to compiling applications using mxmlc. If you are compiling a library (using compc), this option does not exist, and you will get a warning if you try to use it.

remove-circulars

Tells the Apache Royale compiler to remove circular dependencies in the generated JavaScript, where possible.

-remove-circulars

Maven configuration:

<removeCirculars>true</removeCirculars>

show-binding-warnings

Set to false to remove all binding warnings.

-show-binding-warnings=false

Maven configuration:

<additionalCompilerOptions>-show-binding-warnings=false;</additionalCompilerOptions>

skip-transpile

(Advanced) Set to false to skip transpiling ActionScript and MXML to JavaScript, and only run the release build. Generally used by contributors to the compiler only. Default s to false.

-skip-transpile=true

Maven configuration:

<additionalCompilerOptions>-skip-transpile=true;</additionalCompilerOptions>

strict-identifier-names

Determines if names of identifiers must follow the strict rules of ActionScript 3.0, or if they may use the looser rules introduced in ECMAScript 5. Defaults to false.

-strict-identifier-names

source-map

Emits a source map in the debug build for each ActionScript file. The default value is false.

-source-map

Maven configuration:

<additionalCompilerOptions>-source-map=true;</additionalCompilerOptions>

source-map-source-root

Sets a custom value for the sourceRoot property in the generated source map files. This option will be ignored if the source-map compiler option is false.

-source-map-source-root=my/custom/path

Maven configuration:

<additionalCompilerOptions>-source-map-source-root=my/custom/path;</additionalCompilerOptions>

targets

Specifies the target format of the code generated by the Apache Royale compiler. You can specify multiple targets.

-targets JSRoyale,SWF

The compiler supports the following values for “targets”:

  • “JSRoyale”
  • “JS”
  • “JSNode”
  • “JSNodeModule”
  • “SWF”

Maven configuration:

<targets>JSRoyale</targets>

warn-public-vars

Enables or disables warnings about using public variables when it may be considered dangerous to use them.

-warn-public-vars

Maven configuration:

<additionalCompilerOptions>-warn-public-vars=true;</additionalCompilerOptions>

watch

After initial compilation completes, the compiler keeps running to watch for source file changes. When .as or .mxml files are changed, the compiler runs a fast incremental build. Use Ctrl+C to exit the compiler.

-watch

Maven configuration:

<additionalCompilerOptions>-watch=true;</additionalCompilerOptions>
