<ceylon-compile-js> Ant task

Usage

Note: You must declare the tasks with a <typedef>.

This task compiles Ceylon code to JavaScript, by means of the ceylon-js command-line tool.

The <ceylon-compile-js> task is fairly similar to <ceylon-compile>; the difference lies mainly with some options that are specific to JavaScript code generation.

To compile the module com.example.foo whose source code is in the src directory to a module repository in the build directory, with verbose compiler messages:

<target name="compile" depends="ceylon-ant-taskdefs">
  <ceylon-compile-js src="src" out="build" verbose="true">
    <module name="com.example.foo"/>
  </ceylon-compile-js>
</target>

Description

Compiles Ceylon source code to JavaScript and directly produces module and source archives in a module repository

The <ceylon-compile-js> ant task wraps the ceylon compile-js command.

Nested elements

<define>

A <define> element is used to set system properties for the ant task being executed. Equivalent to the --define command line option. Set a system property

The value for the system property can either be passed as a value attribute:

<define key="org.example.helloworld.greeting" value="Hi"/>

or it can be the text between the begin and end tags:

<define key="org.example.helloworld.greeting">Hi</define>

Alternatively, it is posible to dispense with the attributes and use the syntax

<define>org.example.helloworld.greeting=Hi</define>

Element	Description	Required
key	The property to be defined	No
value	The value of the define	No

<files>

Ceylon files to be compiled`

<module>

A ceylon module to be compiled`

A <module> element must specify a name, and may specify a version. If the relevant ceylon task don't require a version it will be ignored.

Element	Description	Required
name	The module name.	Yes
version	The module version. Whether this is required depends on the task	No

<moduleset>

Ceylon modules to be compiled`

A <moduleset> containing a number of <sourcemodule>s and/or <module> subelements. It can be defined at the top level and then used by reference using the refid attribute, so you don't have to repeat the same list of modules all the time.

Element	Description	Required
refid	A reference to a <moduleset> defined elsewhere.	No

<rep>

A module repository containing dependencies. Can be specified multiple times. Defaults to <rep url="./modules"/>.

Element	Description	Required
url	The URL or path of the module repository.	Yes, unless a `refid` is given
refid	A reference to a <rep> defined outside this task.	No

<reposet>

A set of module repositories containing dependencies. Can be specified multiple times. Default to modules.

A <reposet> element contains a number of <repo> and/or <reposet> elements. It can be defined at the top level, and then used by reference using the refid attribute so you don't have to repeat the same list of repositories all the time.

Element	Description	Required
refid	A reference to a <reposet> defined elsewhere.	No

<source>

A <source> path, specifying a source path, for example:

<source>my/src/directory</source>

or

<source value="/src/directory"/>

Equivalent to the --src command line option. Path to source files. Can be specified multiple times; you can also specify several paths separated by your operating system's PATH separator. (default: ./source)

Element	Description	Required
value	The source path.	No

<src>

Synonymous with <source>

Element	Description	Required
value	The source path.	No

<suppressWarning>

Equivalent to the --suppress-warning command line option. Suppress the reporting of the given warnings. If no warnings are given then suppresss the reporting of all warnings, otherwise just suppresss those which are present. Allowed flags include: filenameNonAscii, filenameClaselessCollision, deprecation, compilerAnnotation, doclink, expressionTypeNothing, unusedDeclaration, unusedImport, ceylonNamespace, javaNamespace, suppressedAlready, suppressesNothing.

Suppresses compiler warnings. Warnings can be suppressed by type, for example

<suppressWarning>filenameNonAscii</suppressWarning>

or eqiuvalently

<suppressWarning value="filenameNonAscii">

or all warnings can be suppressed by not naming any specific warnings:

<suppressWarning/>

Element	Description	Required
value	The name of the warning(s) to be suppressed.	No
