Dhall Configuration Language features and specs

  • Deterministic
    Dhall is designed to be a deterministic configuration language, meaning that given the same input, it will always produce the same output. This ensures consistency and repeatability across environments.
  • Type-Safe
    Dhall includes a strong static type system, preventing many common errors associated with misconfigurations. Types are checked at compile time, ensuring configuration values meet specific criteria before deployment.
  • Total Programming Language
    Unlike many other configuration languages, Dhall is a total functional programming language, which means every program written in Dhall will terminate. This prevents infinite loops and other runtime issues.
  • Interoperability
    Dhall can generate JSON, YAML, and other data interchange formats, making it highly interoperable with existing systems that require these formats for configuration.
  • Modular
    Dhall allows for modular configuration files. You can define reusable components and import them across different configurations, promoting DRY (Don't Repeat Yourself) principles.

Possible disadvantages of Dhall Configuration Language

  • Learning Curve
    While Dhall is designed to be simple, the presence of a type system and functional programming concepts can present a learning curve to new users, especially those without a programming background.
  • Tooling Support
    Compared to more established languages, Dhall has less tooling support. Users might find fewer IDE extensions, plugins, or community libraries to assist in development.
  • Limited Ecosystem
    Being relatively new, Dhall has a smaller ecosystem that may lack the breadth of community contributions, such as templates and integration examples, found in more mature configuration languages.
  • Performance Overhead
    The type checking and interpretation of Dhall can introduce some performance overhead compared to more traditional configuration formats like JSON or YAML, which are simpler to parse.
  • Complexity for Simple Configurations
    For simple configurations, the added complexity of Dhall's type system and functional features may be unnecessary, leading to overhead without a clear benefit.

  • Any program can be a GitHub Actions shell
    I'll give a shot at some guiding principals: 1. Do not use yaml. All github action logic should be written in a language that compiles to yaml, for example dhall (https://dhall-lang.org/). Yaml is an awful language for programmers, and it's a worse language for non-programmers. It's good for no one. 2. To the greatest extent possible, do not use any actions which install things. For example, don't use... - Source: Hacker News / 28 days ago
  • StrictYAML
    I'm a fan of anything that moves us away from stringly typed nonsense. See also Dhall (which can render to yaml). I like the idea but found the veneer broke a little too often and left me squinting at Haskell. https://dhall-lang.org/. - Source: Hacker News / about 2 months ago
  • Some Programming Language Ideas
    I think you're asking for Starlark (https://starlark-lang.org), a language that strongly resembles Python but isn't Turing-complete, originally designed at Google for use in their build system. There's also Dhall (https://dhall-lang.org), which targets configuration use cases; I'm less familiar with it. One problem is that, while non-Turing-completeness can be helpful for maintainability, it's not really... - Source: Hacker News / 4 months ago
  • 8 months of OCaml after 8 years of Haskell in production
    > Lambda calculus is as pure as can be, and also has terms that don't normalize. That is not considered a side effect. Many typed lambda calculi do normalise. You can also have a look https://dhall-lang.org/ for some pragmatic that normalises. > A better example of impurity in Haskell for pragmatic's sake is the trace function, that can be used to print debugging information from pure functions. Well, but that's... - Source: Hacker News / 5 months ago
  • Thoughts on ThoughtWorks Radar 2024
    I was first turned onto Pkl during my Dhall Trough of Disillusionment phase (Dhall is cool, but man is it hard) by James Ward. It looked to be a language that had enough types to compile YAML/JSON configuration files wayyyy more safely. I’ve had enough YAML/JSON misconfigurations break production, that I started looking into ways to compile those problems away, and Dhall helped a lot, but the learning curve and... - Source: dev.to / 6 months ago
