What is Catala Programming Language?
Table of Contents
Catala is a domain-specific programming language designed to bridge the gap between human-readable text and executable code. It is a high-level language that prioritizes human understanding and expressiveness. Unlike traditional programming languages that can be challenging to understand for non-programmers, Catala aims to make coding more accessible to a broader audience, including lawyers, regulators, and subject matter experts.
Why was Catala Created?
Catala was created to address a fundamental problem in software development: the gap between legal and regulatory documents written in natural language and the code that implements them. This gap often leads to misunderstandings, errors, and compliance issues. By providing a language that is closer to natural language, Catala aims to reduce ambiguity and make it easier to translate legal and regulatory requirements into executable code.
Features of Catala Programming Language
Here are some key features of Catala programming:
1. Declarative Syntax
Catala employs a declarative syntax that is closer to natural language than traditional programming languages. This feature allows legal professionals, who may not have a strong programming background to read and understand the code more easily. For example, a clause in a contract written in Catala might look like this:
| contract CarRental { when { date of return < date of pickup -> “Invalid return date”; } obligation { date of return > date of pickup -> “Late return fee of $50”; } } |
The code above clearly specifies the conditions and obligations related to a car rental contract.
2. Static Analysis
One of Catala’s most powerful features is its ability to perform static analysis on legal code. It can detect potential issues and conflicts within contracts before they become legal disputes. This proactive approach not only saves time and money but also reduces the likelihood of legal disputes.
3. Modularity
Catala promotes modular coding practices, allowing legal professionals and developers to break down complex contracts into smaller, more manageable components. This modularity enhances code reusability and makes it easier to maintain and update legal documents over time.
4. Multilingual Support
In an increasingly globalized world, legal documents often need to be available in multiple languages. Catala programming language is designed to support multilingual contracts, enabling users to define clauses in various languages and automatically generate translations.
5. Integration with Legal Systems
Catala is not meant to replace legal systems or lawyers but to enhance their capabilities. It can be integrated into existing legal systems and workflows, allowing legal professionals to work more efficiently and accurately. This integration can significantly reduce the time and effort required to draft, review, and execute legal documents.
Key Goals and Principles Of Catala Programming Language
Catala is guided by several key principles and goals:
1. Human-First: Catala prioritizes human readability and comprehension. Its syntax and structure resemble natural language, making it easier for non-programmers to understand and contribute to code.
2. Declarative: The language encourages a declarative programming style, where the focus is on specifying what should be done, rather than how to do it. This leads to more concise and expressive code.
3. Error Prevention: Catala programming language incorporates safety features to catch errors at compile-time rather than runtime. This reduces the likelihood of bugs and improves code reliability.
4. Domain-Specific: While Catala can be used for a wide range of applications, it excels in domains where legal and regulatory compliance are critical.

Syntax and Structure Of Catala Programming
Basic Syntax
Catala’s syntax is designed to resemble natural language as closely as possible. Here’s a simple example of a variable declaration in Catala:
| let age: number = 30 |
In this example, we declare a variable ‘age’ of type ‘number’ and assign it the value ‘30’. The syntax is clear and concise, making it easy for anyone to understand.
Variables and Data Types
Catala programming language supports a range of data types, including numbers, strings, booleans, and custom data types. Variables are declared using the ‘let’ keyword, as shown in the previous example.
| let name: string = “Alice” let isAdult: boolean = true |
Control Structures
Catala provides familiar control structures like ‘if’, ‘else’, and ‘while’ loops. Here’s an example of an ‘if’ statement:
| if (age >= 18) { “You are an adult” } else { “You are a minor” } |
Functions and Modules
Functions in Catala are defined using the ‘fun‘ keyword. They can take parameters and return values. Here’s a simple function that calculates the square of a number:
| fun square(x: number): number { x * x } |
Modules allow you to organize your code into reusable components. You can import modules using the ‘import’ keyword and access their functions and variables.
| mport math from “math” let result = math.square(5) |
Use Of Catala Programming Language
Let’s explore the major uses of Catala programming:
Legal and Regulatory Compliance
One of the primary uses of Catala is in the field of legal and regulatory compliance. Lawyers and regulatory experts can use Catala to translate complex legal documents and regulations into executable code. This ensures that software systems adhere to legal requirements, reducing the risk of non-compliance and legal disputes.
For example, Catala can be used to automate contract generation, ensuring that contracts are always in compliance with the latest legal changes.
Financial Applications
Catala’s DSL capabilities make it well-suited for financial applications. Financial institutions can use Catala to encode complex financial calculations and regulations in a way that is both accurate and easily maintainable. In the realm of finance, precision and compliance with ever-evolving regulations are paramount.
Natural Language Interfaces
Catala’s natural language-like syntax isn’t just about making code accessible to non-programmers; it’s also about creating interfaces that feel intuitive. This opens up exciting possibilities for creating natural language interfaces for software applications. Imagine a voice-activated personal assistant that understands your commands in plain language and executes complex tasks. Catala programming language can play a pivotal role in bringing this vision to life.
For instance, in a voice-controlled financial application, you could say, “Calculate my monthly mortgage payment based on a 30-year loan with a 4% interest rate,” and Catala would interpret and execute the command accurately.
Education and Accessibility
Education is another domain where Catala shines. It simplifies the learning curve for programming, making it an ideal choice for teaching coding to beginners. With its human-readable syntax, students can grasp programming concepts more easily, fostering a deeper understanding of the subject.
Moreover, Catala can enhance accessibility for individuals with limited programming experience or disabilities. It can power applications that assist users with everyday tasks through natural language interactions, promoting inclusivity in technology.
