Developing Concurrently on 4D Server in Project Mode

Since its release in 4D v18, Projects drastically expanded 4D’s capabilities by bringing compatibility with version control systems —among other things.

With excellent feedback, we couldn’t be prouder to see significant adoption of this feature among the 4D community. This pushed us to improve it to make it even better. 

Your feedback included a request for the possibility to work simultaneously on a single development server as a team. Again, 4D listened, and we are thrilled to announce that with 4D v19 R6, you can work on a development server in project mode!

4D and Git: From Beginner to Expert

So by now, you know that projects come with a tremendous benefit: the ability to use Git (the revision control system) and GitHub (the hosting service) to get your 4D application up and running in a more productive development environment.

Newbie or full-fledged senior developer version control has been a staple in every work environment where multiple resources collaborate to participate in what could be called a software chain of production.

To help you get familiar with Git, we’ve made available many resources at your disposal. This blog post is a compilation of everything we’ve provided on this topic… so far. If you feel lost and don’t know where to start, keep reading; we’ve included:

  • other blog posts,
  • a detailed guide,
  • a top-rated summit video,
  • and even a training course.

Saving project source code without tokens

Commands, constants, tables and fields are stored with their tokens in the project source code files (4dm files). This allows 4D to rename them automatically. But sometimes, you would like these source code files to be stored without tokens for a better readability with a version control system or an external code editor, or for better code sharing between projects. Let’s see how to make 4D store source code without these tokens.

Quickly jump to different functions of a class

Classes were introduced with 4D v18 R3. They allow you to organize your business logic and separate it from the UI part more quickly.

Classes are composed of several functions of varying lengths, so it’s not always easy to find the function you want to modify, or to move from one function to another. You can use the explorer, which displays classes and functions, but when you’re coding in the editor window, you don’t want to waste time changing windows.

With 4D v19 R4, the list of functions in your class is displayed in the code editor toolbar, allowing you to easily jump to a specific function.

An introductory guide to 4D and Version Control Systems

For many years, 4D has allowed you to develop binary databases as part of a team with a 4D Server. This way of developing is straightforward, but many developers asked us to be more efficient on source code management to deliver better traceability. 4D has heard them and developed Project mode to fit this need. This mode opened a new era of collaboration thanks to version control systems!
