===================================

Installation guide

Theia Generator can be installed locally or globally

Here is how to install it globally:

using yarn:

$ yarn global add @eclipse-che/theia-generator

using npm:

$ npm install -g @eclipse-che/theia-generator

Then, a new command line tool is available : che:theia

Using the tool

Once the tool is installed, the following commands are available:

• che:theia init
• che:theia production

(help is also available with command che:theia --help)

che:theia init

This command needs to be launched inside a cloned directory of Eclipse Theia cloned directory

$ git clone https://github.com/theia-ide/theia
$ cd theia
$ che:theia init

once the init command has been launched:

• inside theia/che folder, all extensions and plugins have been cloned and checkout to their correct branches (if specified)
• all extensions have their package.json updated to the versions used by the current theia. (cloned)
• in packages folder, there are symlinks for each extension coming from theia/che folders. All packages are prefixed by @che-
• in plugins folder, there are symlinks for each plugin coming from theia/che folders.
• in examples folder, a new folder named àssemblyhas been generated and include theche-theia` assembly of Theia

In order to build the product, just run yarn at the root folder (where theia has been cloned)

Custom extension and plugin set

Also you can provide custom yaml with your extension set, by using -c or --config parameter of che:theia init :

che:theia init -c ./path/to/custom/che-theia-init-sources.yaml

The sample of che-theia-init-sources.yaml can be found there

Dev mode

Dev mode is the way to use all new extensions from master branch:

che:theia init -d

And che:theia will use master branch for all extensions and plugins, regardless of provided configuration

Development life-cycle

Che Theia should be built from root directory only (Root directory of Che Theia is the directory into which Theia was clonned and che:theia init was executed there). In case of building from subdirectories it will mess up dependencies, don't do it.

To build whole Che Theia just execute yarn command in the root directory. If only one module should be built, use npx run build <module-name>. For example npx run build @theia/plugin-ext.

Also one may set compilation on changes for some modules. To do so, run npx run watch <module-name> from the root directory. Then execute yarn watch from examples/assembly folder and run Che Theia with yarn run start command from the same directory. Make sure, you start watcher for all modules under development.

Note, this is not the case for embedded plugins. To develop them one should place copy of their sources somewhere else (outside of the Che Theia folder) and then include new binaries into the assembly.

Compiling the plugins

Plugins have to be compiled separately with the script plugins/foreach_yarn. This script simply run the yarn command on each subfolders of plugins and copy the .theia package in production/plugins folder to be reused by the che-theia product.

che:theia production

A production's ready assembly of che-theia can be obtained by running from the root folder of theia: che:theia production

It will generate in ${where theia has been cloned}/production folder a ready-to-use assembly of theia, without lot of files (like source maps, source code, etc)

It can be started with the command node ${where theia has been cloned}/production/src-gen/backend/main.js

che:theia clean

If you want to clean up your Theia repository use che:theia clean command, and it will undo all modification on your repository
