Bundle of templates

A Telosys project may require a lot of templates, that's why the templates are organized in "bundles".
A "bundle" is just a set of "templates" (and sometimes resources) grouped together in a folder.
Thus it is possible to have clearly defined groups of templates for each part of the code to be generated (persistence, REST-API, DTO, HTML pages, testing, etc)

What's in a bundle ?

Each bundle folder contains:
  • 1 file "templates.cfg" (mandatory)
  • 1 file "" (to provide information about the bundle)
  • 1..N templates (Velocity ".vm" files)
  • 0..N resources files (static files)
  • any other useful file for the bundle
  • 0..N subfolders (to organize the different files)

How it works ?

All code generation is driven by the "templates.cfg" file. This file defines the target files to generate, the directory in which to place the result and the templates to use. For example, if a template (".vm" file) is present in the bundle folder but not present in "templates.cfg", it will not be used.
The "templates.cfg" file is used to launch different types of processing defined by the last character of each line:
  • "*" : code generation executed multiple times with the same template (1 time for each selected entity)
  • "1" : code generation executed only once independently of entities
  • "R" : simple resources files copy in a destination folder

How to install a bundle?

Whatever your Telosys tool (CLI or Eclipse), it allows you to install remote bundles from GitHub.

Installation from GitHub with Telosys-CLI

Use the following commands :
  • "gh" ("GitHub") to print/change the current GitHub account
  • "lb" ("list bundles") to see the bundles already present in the current project
  • "ib" ("install bundle") to install new bundle(s) from the remote Git repository

Installation from GitHub with Telosys Eclipse plugin

In the project properties / "Telosys tools" - Select "Templates" tab - Choose your GitHub account - Click "Get available bundles" - Select the desired bundles - Click "Download selected bundle(s)" with "Install downloaded bundle(s)" checked

Installation from any Git remote repository with Git

You can install a bundle from any Git repository just using Git commands.
Get the Git repository URL for the bundle to install (on your remote Git server). For example : http://server-name/xxx/yyy/bundle-name.git
Clone the Git repository in the Telosys project templates directory. For example : git clone http://server-name/xxx/yyy/bundle-name.git
There you have it. You can now use the bundle to generate your code and eventually modify it and update it on the remote Git repository (with git commit and push).

How to customize a bundle?

Telosys was designed to allow users to customize code generation. So, if you reuse existing bundles, you will probably want to change some its parts.
What you can do:
  • modify existing templates (.vm files) with a text editor
  • add new templates (.vm files) in the bundle (don't forget to reference them in "templates.cfg")
  • delete certain templates (in this case you can only delete the line in "templates.cfg")
  • add new resources (static files) to be copied

How to create a new bundle?

  • Create the bundle folder in "TelosysTools/templates" (the folder name is the bundle name)
  • In the new folder : - Copy an existing "templates.cfg" file and adapt it - Create a "" file - Create (or copy/paste/modify) the bundle ".vm" files

How to publish a bundle?

Once you've created (or customized) a bundle, you might want to publish it as a Git repository so that you can reuse it later from anywhere.
Here's the procedure to follow:

1) Prepare the local Git repository

The bundle folder will become a Git project. So, in the bundle folder...
  • Initialize the Git repository with initial branch “master” $ git init -b master
  • You can also define your user name and email for the current repo (optional) $ git config "Your Name" $ git config [email protected]
  • Add all the bundle files to be committed $ git add .
  • Commit the files $ git commit -m "Initial commit"

2) Publish on remote repository

On the remote Git server (GitHub, GitLab, your own server, etc): - if you don't already have a repository to host the bundle, create it. - copy the repository URL For example : or
On the local bundle folder:
  • Add the remote repository as a new remote (with name “origin”) $ git remote add origin https://xxx/yyy/repo-name.git
  • Check Git remote $ git remote -v origin https://xxx/yyy/repo-name.git (fetch) origin https://xxx/yyy/repo-name.git (push)
  • Push to remote “origin” (the GitHub repository) $ git push origin master (if not authenticated Git ask for user & password)
And that's all. The remote Git repository contains now all the bundle files. The bundle is now installable by Telosys on any workstation.
