Ceylon distribution

Here you can find out how to build a Ceylon distribution from code.

Distribution layout

  • bin - Unix/Windows commands
  • contrib - Sample Ceylon command-line plugins
  • doc - Documentation about Ceylon including the spec in HTML and PDF format
  • lib - Required libraries for the Ceylon commands
  • repo - Required bootstrap Ceylon modules (language, tools)
  • samples - Sample Ceylon modules
  • templates - Templates for new Ceylon projects
  • LICENSE-ASL - The Ceylon ASL license
  • LICENSE-GPL-CP - The Ceylon GPL/CP license
  • README.md - This file

Building the distribution

To begin, make sure you have:

  • the Java 7 JDK or Java 8 JDK and Ant 1.8+ installed and that both are working correctly (if you installed Ant using your platform's package manager make sure it installed the ant-junit.jar as well, which can be found in a package named ant-junit or ant-optional depending on your distribution)
  • Git set up correctly
  • created a new directory for the Ceylon project
  • opened a terminal and changed to the newly created directory

And now you either set things up for HTTPS access (recommended for most people):

  • Clone ceylon:
$ git clone https://github.com/ceylon/ceylon.git

(If you encounter an issue like "fatal: unable to access 'https://github.com/ceylon/ceylon.git/': Failed connect to github.com:443; No error", make sure you've set up your proxy as git config, ie:

    $ git config --global http.proxy http://userName:password@proxyServer:port

that should fix it.)

  • Go into the newly created ceylon directory and build the complete distribution by running:
$ ant clean dist

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 PATH environment variable (either by adding the bin folder to your 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

$ git pull --rebase
$ ant clean dist

NB: The git pull --rebase 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:
    • browse - Open module documentation in the browser
    • classpath - Print a classpath suitable for passing to Java tools to run a given Ceylon module
    • compile - Compile a Ceylon program for the Java backend
    • compile-js - Compile a Ceylon program for the JavaScript backend
    • config - Manage Ceylon configuration files
    • copy - Copy modules from one module repository to another
    • doc - Document a Ceylon program
    • help - Display help about another tool
    • info - Print information about modules in repositories
    • import-jar - Import a Java .jar file into a Ceylon module repository
    • new - Generate a new Ceylon project
    • plugin - Package or install command-line plugins
    • 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
    • test-js - Test a Ceylon program on node.js (JavaScript)
    • version - Show and update version numbers in module descriptors
    • war - Generate a WAR file from a compiled .car file

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

  • repo/ceylon/language/1.2.1/module-doc/api

Running the sample programs

To compile and run the samples, read the README.md contained in the samples sub folder for instructions.

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:

ceylon help compile

Setting up Eclipse

See README.eclipse for the instructions in setting up your Eclipse environment for Ceylon development.

Ant tasks for Ceylon

We include support for Ceylon ant tasks which are documented at http://ceylon-lang.org/documentation/1.2.1/reference/tool/ant/.

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

cd samples/helloworld
ant
