Modern Natural Development with NaturalONE – Legacy Coder Podcast #3

Modern Natural Development with NaturalONE

Why would anyone dismiss the good old Natural editor and switch over to NaturalONE? Let’s find out what features NaturalONE has to offer in the third episode of the Legacy Coder Podcast.

Why should you switch over to NaturalONE?

  • Increased developer productivity
    • Use Copy and Paste (duh!) for high quality Natural programming 😉
    • Syntax Highlighting will help you understand the source code faster.
    • Make use of intelligent search and replace features with regular expressions.
    • Code Completion makes you type way less than before.
      Code Completion in NaturalONE
    • Code Navigation (jump to a variable definition etc.) lets you explore the code base with a few keystrokes.
    • You can use Code Folding for focussing on the really important stuff.
    • Multiple compile errors are displayed instantly without uploading the source to the server.
      Multiple compile errors in NaturalONE
  • Repository based development
    • Finally develop software like the cool kids do!
    • Every code change is documented and can be rolled back with just a few commands. It can even be attached to an issue tracker like Jira or Redmine.
      Git integration in NaturalONE
    • You can try out new things in an isolated environment.
    • You can automate your coding with code generators like Xtext.
  • Modernize your development environment
    • Share knowledge and open up towards other (maybe younger) developers (Java etc.).
    • Be and stay attractive as a company to new employees.
    • Automate your build process
    • NaturalONE is Software AG’s platform of choice for the future.
    • The old Natural editor will be shut down!
  • Extendable with additional plugins
    • Software AG’s innovations will only take place in NaturalONE (e.g. Code Coverage, Screen Testing).
    • Attach your IDE to an issue tracker like Jira or Redmine with Mylyn.
    • Use Snipmatch for even less typing. Plugin Snipmatch used in NaturalONE
    • Create your own extensions (e.g. NatUnit) for whatever requirement you have.

Automating Your Natural Build Process – Legacy Coder Podcast #2

Automating Your Natural Build Process

How can you automate the build process for your application based on Software AG’s Adabas and Natural? I talk about our journey towards a completely automated build from scratch after each push to Git in the second episode of the Legacy Coder Podcast.

How to automate the build process for an Adabas/Natural application

  • Why would I want to automate the build process?
    • What hurts should be done more often!
    • No more long integration phases before each release!
    • You’ll get a faster time to market for new features.
    • You can get rid of knowledge silos concerning the release of your application.
  • What steps may need to be automated?
    • Upload (transfering the Natural source code to the server)
    • Compile (CATALOG, STOW, CATALL etc.)
    • Unit Tests (e.g. with NatUnit, see Unit Testing Natural Applications)
    • Deployment (the actual release of the new version on the target stage)
    • Restarting RPC servers or whatever individual steps might be necessary in your environment
  • What tools are available for automating the Natural build process?
    • It all starts with Git or any other versioning control system (Subversion, TFS, CVS).
    • You can use Jenkins for Continuous Integration.
    • Software AG’s command line tools (ftouch etc.) can be scripted.
    • Even the CATALL can be scripted by calling into Natural BATCHMODE.
    • NaturalONE’s ant scripts for uploading and compiling Natural sources.
    • Any additional tool that you might need (Bash scripts etc.)
  • How can I get started?
    • Make your project fully compilable. There can be no compile errors whatsoever.
    • Start with a single step, e.g. automate only the compile step first.
    • Script everything (e.g. with Bash) right from the beginning. You can easily call these scripts from Jenkins later on.
    • Hook Jenkins up to your source code repository. It provides plugins for every major system (e.g. Git, Subversion).
    • Try to automate the build with Jenkins. It’s completely free and easy to setup. Perhaps ask a Java colleague if he can help you.
  • How can you go even further than what’s possible today?
    • Try to automate imports of Adabas data that’s important for your application.
    • Try to automate Adabas schema migrations.
    • Implement feature toggles for more fine grained control over your application’s functionality at runtime.

Unit Testing Natural Applications – Legacy Coder Podcast #1

Unit Tests for Natural Applications with NatUnit

Unit testing with Software AG’s Natural – is that even possible? Let’s find out in the very first episode of the Legacy Coder Podcast.

Unit testing Natural applications

  • Why would I want to unit test my Natural code?
    • You get instant feedback whether your code works. That’s fun! 😀
    • You get a safety net for refactoring and optimizing your Natural code.
    • You can catch regression as early as possible. That makes evolving your code base easy and painless.
    • Unit tests can be integrated into your build process (Continuous Integration, Continuous Delivery, Continuous Deployment).
    • Unit tests are the first step on your way to a fully automated build process.
  • What tools are available for unit tests with Natural?
    • Subprogram testing within NaturalONE
      • Only subprograms can be tested.
      • Different “language” for defining your tests.
      • Tests have to be defined manually from a GUI.
      • Tests cannot be executed from within Natural itself.
      • Proprietary software maintained by Software AG.
      • Professional support by Software AG is available.
    • NatUnit – an open source framework for unit testing with Natural
      • Everything that can be called from a subprogram can be tested (subprogram, subroutine, function).
      • Tests are written in the same language that is used for production code.
      • Tests can be written as Natural code with full IDE support.
      • Tests can be executed within any Natural runtime.
      • Open source project that can be extended by everybody – including yourself.
      • There’s no professional support for the framework.
  • What do I have to do differently when writing testable Natural modules?
    • You need more fine grained modularization!
    • You have to decouple the User Interface, Database access, and the core Business Logic from each other.
    • You need to extract the functionality to test into its own callable module.

NatUnit in action

Here are a few screenshot of our NatUnit Eclipse plugin in action.

You can run a NatUnit test from within the IDE.

NatUnit Eclipse Plugin: RunAs NatUnit Test

If the tests are successful, you instantly see the famous “green bar”.

And if the tests are broken, you’ll definitely notice that, too. 😉
