Is Haskell Good for Scripting?


Scott Campbell

Haskell is a programming language that is known for its strong type system, lazy evaluation, and functional programming paradigm. While it is often praised for its use in building large-scale applications and solving complex problems, one may wonder if Haskell is a good choice for scripting tasks. In this article, we will explore the features of Haskell and discuss its suitability for scripting purposes.

What is Scripting?

Scripting refers to the process of writing small programs or scripts that automate specific tasks or perform simple computations. These scripts are usually interpreted rather than compiled, allowing for quick prototyping and easy modifications. Scripting languages are commonly used in system administration, web development, and data manipulation.

The Advantages of Haskell

Haskell offers several features that make it a powerful language for building applications. Let’s take a look at some of these advantages:

  • Strong Type System: Haskell has a strong static type system that helps catch errors at compile-time, reducing the likelihood of bugs in your code.
  • Laziness: Haskell uses lazy evaluation, which means that expressions are only evaluated when their values are needed. This can be beneficial in scripting scenarios where you want to avoid unnecessary computations.
  • Functional Programming Paradigm: Haskell encourages pure functional programming, which promotes immutability and helps write clean and modular code.

Haskell’s Suitability for Scripting

While Haskell has many advantages, it may not be the best choice for all scripting tasks. Here are some factors to consider:

  • Learning Curve: Haskell has a steep learning curve compared to some other scripting languages like Python or Ruby. If you are new to Haskell, it may take some time to become proficient.
  • Libraries: The availability of libraries and packages is crucial for scripting.

    While Haskell has a rich ecosystem of libraries, it may not have the same breadth and diversity as more mainstream scripting languages.

  • Interoperability: Interoperability with other tools and systems is an important aspect of scripting. Haskell, being a compiled language, may require additional effort to integrate with existing scripts or tools.

Use Cases for Haskell Scripting

Although Haskell may not be the most popular choice for scripting tasks, there are certain scenarios where it can shine:

  • Data Manipulation: Haskell’s strong type system and functional programming features make it well-suited for processing and transforming data.
  • Numerical Computing: If your scripting task involves heavy numerical computations or complex algorithms, Haskell’s lazy evaluation can provide performance benefits.
  • Domain-Specific Languages (DSLs): Haskell’s expressive syntax and type system make it an excellent choice for creating DSLs tailored to specific domains or problem spaces.


In conclusion, while Haskell may not be the most conventional choice for scripting tasks due to its learning curve and potential interoperability challenges, it offers numerous advantages such as a strong type system, laziness, and functional programming paradigm. It can excel in scenarios involving data manipulation, numerical computing, or creating domain-specific languages. Ultimately, the suitability of Haskell for scripting depends on the specific requirements of your task and your familiarity with the language.
