If you manage a custom JMP application, you may not have a DevOps team that codes in JMP Scripting Language (JSL). But that shouldn’t stop you from harnessing the most effective development practices available today.

This article will provide you six development resources (used by the Predictum DevOps team!)to help you code proficiently in JSL.

1: Use a Text Editor

Using a text editor makes coding an easier experience. This software is designed for heavy-duty coding and gives you a comfortable, organized space to create the custom JMP applications you need.

Of course, nothing is stopping you from writing JSL code in JMP software’s default editor. In fact, it’s useful for small scripts and quick tasks. However, you will find yourself overwhelmed if you are managing thousands of lines of code or supporting the needs of multiple departments in your business.

At Predictum, we use Visual Studio Code (VS Code for short). It’s a well-supported editor with a wide array of workflow automation plugins, such as syntax lint readers, command lines, and deployment tools. No matter what text editor you choose, you will be able to manage larger codebases and facilitate development of custom JMP applications.   

2: Download Predictum’s JSL for VSCode Plugin

If you use VS Code, here’s an opportunity to make life a lot easier for yourself: Predictum’s very own JSL Plugin for VS Code Editor. 
This easytouse plugin adds JSL syntax to your editor. Now, when you develop, VS Code will recommend the scripts and code you need within keystrokes. To learn more and download, you can visit Predictum’s GitHub JSL project, where you can see project updates and maintenance by our DevOps team. 

3:  Post Questions about Your JSL Challenges on the JMP User Community

In my early days as a JSL coder at Sanofi Pasteur, I was tasked with creating annual product report graphs for our data science teams. Sure, I had my own knowledge and resources available, but for problems I couldn’t solve I quickly found a wealth of industry and hands-on knowledge at JMP Discussions. 

The JMP User Community and its discussion boards give you a deep community of experience across industries and JMP use cases. It is the definitive support forum for JSL coders of all skill levels. Our Predictum staff are active members of JMP Discussions, contributing to its knowledge share.

If you have a problem, post it to JMP Discussions. Perhaps some of our team members will chat with you! And, by the way, you might make some new friends and partnerships there. Now, that’s a deal!  

4: Use Version Control for Your JSL Scripts with GitLab, Git, or GitHub

Version control is critical in software development across the world. Why shouldn’t it be for JMP scripting?  That’s where Git hosting solutions, such as GitLab, come in.

Git is an open-source version control software, originally authored in 2005 by Linus Torvalds for use in Linux development. Nowadays, Git, its cloud-based sibling GitHub, and GitLab are viable solutions for managing mission-critical, custom JMP applications. For proprietary knowledge work in a larger organization, you may want to consider using GitLab.  

GitLab acts as a central repository, keeping internal scripts securely managed in a company’s internal network. Implementing a GitLab server internally will take individual and team-based work to the next level.

At Predictum, deployment services are a standing part of our development framework, the Predictum System Framework (PSF).

With our unique, integrated GitLab-PSF DevOps platform, we can run JSL scripts in our clients’ custom applications and rigorously test any new changes made to them. We perform automated testing and validation, pairing JMP’s Hamcrest functionality with GitLab. This is to ensure our clients’ applications work error-free as intended. If the testing and validation conditions are met, we deploy clients’ custom applications on their desired version of JMP or JMP’s latest version (and even early adopter versions, when available!)


For process-monitoring teams, ensuring that code works error-free as intended and is compatible with JMP’s statistical discovery platform is critical. You can’t have that ability without a strong application environment for version control and documentation.

5: Hit the Books! JSL Guides and Documentation

One sure-fire way to notch up on your JSL skills is to read the JMP Scripting Guide. Every JMP application comes with the JMP Scripting Guide included in the application interface. To get started, launch JMP and use the following navigation: 

Help > JMP Documentation Library. Select “Scripting Guide” in the table of contents.

Other resources offered online by JMP software include: 

You can only become a better JSL developer by reading JSL documentation and working on your applications habitually. The Buddha says, “Drop by drop is the pot of water filled.” If you are able, set time aside to read and practice. It is an investment in yourself as a skilled JSL coder and JMP user, and in your custom application’s ability to deliver steadfast insights.

6: Know When to Consult a DevOps Team

Maintaining custom JMP applications is typically not the primary job of the engineers and scientists who learn JSL to meet a pressing business need.

The challenge grows exponentially when JSL scripts get passed on to others extend and maintain, or the original code author is no longer available to help. When the problems or challenges occur in running your custom application, you, as the developer, will end up pressed to provide support. Add to it that others in your company may request feature enhancements to meet emerging business needs. All said and done, some JSL developers end up living the expression: “No good deed goes unpunished.” 

When your custom applications don’t meet your changing business needs, it may be time to work with a fast, effective DevOps team. 

Predictum’s DevOps team offers highly skilled software engineers who are proficient in JSL development to build and maintain custom JMP applications that meet your organizational needs.

We can help get your custom application back on track and maintained in a DevOps environment that facilitates building feature enhancements, testing for quality assurance, and effective version control.  Want to see how? Check out our development practices and our recent client success stories! 

The result is software quality assurance of a higher standard and greater robustness, reliability, and scalability of your custom software applications.
