Ceylon distribution

This is the 1.1 "Unflatzburged" release of the Ceylon command line tools (version 1.1.0). This is a production version of the platform.

Ceylon is a programming language for writing large programs in a team environment. The language is elegant, highly readable, extremely typesafe, and makes it easy to get things done. And it's easy to learn for programmers who are familiar with mainstream languages used in business computing. Ceylon has a full-featured Eclipse-based development environment, allowing developers to take best advantage of the powerful static type system. Programs written in Ceylon execute on any Java 7 compatible JVM or Node.js.

Building the distribution

Make sure you have the Java 7 JDK and Ant 1.8+ installed and that both are working correctly
Make sure you have Git set up correctly
Make sure you have GitHub SSH access set up correctly

For the rest of the steps this assumes you have cloned the ceylon-dist repository and you are currently inside it reading this file. If not first do:

Create a new directory for the Ceylon project
Inside that directory clone ceylon-dist by typing

$ git clone git@github.com:ceylon/ceylon-dist.git

Now that you have everything you need continue with the following steps:

Go into the newly created ceylon-dist directory and run the setup

$ cd ceylon-dist ; ant setup

Now to build the complete distribution run

$ ant clean publish-all

After this you'll have a newly built distribution in the dist folder of your current directory. You can run the ceylon command without any further setup or installation by simply running

$ dist/bin/ceylon

But it's advisable to add the ceylon command to your class path (either by adding the bin folder to your class path or by creating a symbolic link to it in an appropriate place like ~/bin/).

If at any time you want to update the distribution to the latest code from GitHub just run

$ ant update-all
$ ant clean publish-all

NB: The update-all command assumes that your projects are "clean", that is you don't have uncommitted changes. If that's not the case you'll have to manually update those projects or first stash your changes (using git stash).

After the build finishes the command line tools will be located in the bin directory.

bin/ceylon - The ceylon tool which provides at least the following subcommands:
- new - Create a new Ceylon project
- compile - Compile a Ceylon program for the Java backend
- compile-js - Compile a Ceylon program for the JavaScript backend
- doc - Document a Ceylon program
- info - Print information about modules in repositories
- new - Generate a new Ceylon project
- run - Run a Ceylon program on the Java VM
- run-js - Run a Ceylon program on node.js (JavaScript)
- src - Fetch source archives from a repository and extract them
- test - Test a Ceylon program on the Java VM
- version - Show and update version numbers in module descriptors
- import-jar - Import a Java .jar file into a Ceylon module repository
- help - Displays help about another tool

The API documentation for the language module ceylon.language may be found here:

repo/ceylon/language/1.0.0/module-doc

Running the sample programs

To compile and run the samples, start from the distribution directory containing this file.

Sample module

To run the "hello world" program, type:

cd samples/helloworld

For Java:

../../bin/ceylon compile com.example.helloworld
../../bin/ceylon doc --non-shared --source-code com.example.helloworld
../../bin/ceylon run com.example.helloworld/1.0.0 John

For JavaScript:

../../bin/ceylon compile-js com.example.helloworld
../../bin/ceylon run-js com.example.helloworld/1.0.0

Sample with no module

To run a program defined in the default module, type:

cd samples/no-module

For Java:

../../bin/ceylon compile default
../../bin/ceylon doc --non-shared --source-code default
../../bin/ceylon run default

For JavaScript:

../../bin/ceylon compile-js default
../../bin/ceylon run-js default

Sample module with Java interoperability

To run the "Java interop" program, type:

cd samples/interop-java
../../bin/ceylon compile com.example.interop
../../bin/ceylon doc --non-shared --source-code com.example.interop
../../bin/ceylon run com.example.interop/1.0.0 John

Note: this is only available for the Java backend.

Tool usage

To see a list of command line options for a particular subcommand use the help subcommand. For example, to get help on the compile tool:

./bin/ceylon help compile

Ant tasks for Ceylon

We include support for Ceylon ant tasks which are documented on at http://ceylon-lang.org/documentation/1.0/reference/tool/ant/.

To run the "hello world" program using ant, type:

cd samples/helloworld
ant

Systems where Ceylon is known to work

Since Ceylon is running on the JVM it should work on every platform that supports a Java 7 compatible JVM. However we have tested the following platforms to make sure it works:

Linux

Ubuntu "quantal" 12.10 (64 bit) JDK 1.7.0_09 (IcedTea) Node 0.10.15
Fedora 17 (64 bit) JDK 1.7.0_09 (IcedTea)
Fedora 16 (64 bit), JDK 1.7.0_b147 (IcedTea)

Windows

Windows 7 (64 bit) 1.7.0_05 (Oracle)
Windows Server 2008 R2 SP1 JDK 1.7.0_04

OSX

OSX 10 Lion (10.8.5) JDK 1.7.0_40 (Oracle) Node 0.10.17
