Build strategic advantage with DSLs

Domain-Specific Languages (DSLs) are purpose-built languages tailored to your business logic. They provide a way to express complexity clearly, accelerate delivery, and protect institutional knowledge. If you’ve ever wondered how to create domain-specific languages that truly enhance your development process, this course is for you!

DSLs are worth exploring when your domain complexity outgrows general-purpose tools.

A Domain-Specific Language can be a strategic asset when clarity, control, and efficiency are top priorities.

If your business logic is becoming too specialized for off-the-shelf solutions, DSLs offer a tailored approach.

When standard languages can’t keep up with your evolving domain needs, it’s time to think DSLs.

What are the struggles?

Communication Challenges
You spend a lot of energy making your experts and your developers communicate. You try every trick in the book! You use analysts to try to bridge the gap, and you write long documents of requirements that are a pain to write and difficult, or even impossible, to keep updated.
Long feedback cycles
You need to go back and forth: developers ask for clarifications and experts get frustrated. Developers get frustrated with receiving ideas that look half-baked to them. They miss the necessary details, prove incomplete and confused when trying to translate them into code.
Extended time-to-market
The process takes way longer than it should be: the ideas look simple, according to your experts, but it takes months at best to translate them into actual code. You won’t be able to react very quickly to the demand: this will cost you time and money.
Error-prone
Everyone makes mistakes, but some errors could be prevented if the experts had a system to analyze their work. It is when developers translate the experts’ ideas into code that you can “debug” them. Errors found late cost so much more than if you found them immediately.

It is nobody’s fault!

Don’t let outdated technology hold you back. Rising costs, security gaps, and limited scalability hold your business back. The longer you wait, the greater the impact. Modernize now to stay competitive and agile.

What can DSLs do?

A Domain-Specific Language (DSL) gives you the power to express complex ideas in a form that’s native to your business domain. Instead of bending general-purpose code to fit your needs, a DSL lets you encode rules, workflows, and logic in a way that’s intuitive, precise, and reusable.

Reduced feedback cycles: experts can experiment the DSL editor provides immediate feedback.
Experts can experiment because the DSL editors provides immediate feedback.
Shorter time to market
Iterations are much faster, and you can build your products more quickly.
Reduced errors
The DSL is a high-level language that captures many mistakes, even conceptual ones.
Increase productivity
The DSL abstracts away technological details and can make experts 10x more productive.
Preserve knowledge
Code is knowledge, and DSL code can be preserved across technological evolutions.

Designing a DSL is a process, not a recipe.
What you’ll get with
this course

There is no recipe to design a DSL: there is no standard solution to apply each time the same. Based on our experience, we have elaborated a process to implement an effective way to create a tool. A series of steps to make your company come together and create the tool that will make you more productive.

01A Clear Understanding of DSLs Fundamentals
Learn when and why to use Domain-Specific Languages, and how they differ from general-purpose programming tools.
Go from concept to implementation, with practical exercises that guide you through building a language tailored to a specific domain.
Discover how to create editors, parsers, interpreters, and other essential tools to make your DSL usable in real-world environments.
Learn how to introduce a DSL in your organization, get buy-in, and integrate it with existing systems and team workflows.

What this course covers that the free articles do not

Design, not syntax

Lessons 4 and 5 are an interactive process for designing a language and a DSL assessment: how to decide what the language must be able to say and, harder, what it must refuse. Grammar syntax is the part you can already learn for free; deciding what belongs in the language is the part that is not written down anywhere.

Including the decision not to build one

Lesson 3 is a guide to working out whether you should create a DSL at all. A course that could only ever conclude yes would not be worth your team’s time. Some domains are better served by a configuration file, and the lesson says when.

Two languages actually built

Lessons 7, 8 and 9 build a textual language and a graphical one, so the technology comparison in Lesson 6 is made against something you have implemented rather than read about. The bonus section adds worked examples and interviews with other practitioners.

Delivered to your team, on request

This is not a recording you buy and watch alone. We deliver it for a team, so the questions asked during it are about your domain and your codebase. Contact us to book it.
