Unleash features and specs

  • Flexibility
    Unleash provides a highly flexible feature management system that allows teams to enable or disable features without deploying new code. This is particularly useful for A/B testing, gradual rollouts, and quick feature toggles.
  • Open Source
    Being an open-source platform, Unleash allows you to review the source code, contribute to improvements, and avoid vendor lock-in. This provides a greater degree of transparency and control.
  • Multiple Environment Support
    Unleash supports multiple environments (development, staging, production) out of the box, enabling seamless management of feature releases across different stages of software development and deployment.
  • Strong Community
    As an open-source project, Unleash boasts a strong community that contributes to its constant improvement and provides support through forums, documentation, and other channels.
  • Privacy and Security
    Unleash allows self-hosting, which can be a significant advantage for organizations concerned about data privacy and security. Self-hosting ensures that no feature flag data leaves your infrastructure.

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.

  • KILLSWITCH
    So my first instinct is to setup some sorta feature-flag thing within a CMS so managers can flip the boolean, I'm exploring getunleash.io and GrowthBook.io and we already use Contentful.com within the app but they're saying they "really don't think we need to use any third party thing for a killswitch"...

  • Need your opinion
    We are an Open Source Feature Flagging solution called Unleash, and we are looking to get some feedback from the community on a decision we are trying to make. We are considering offering our developers the option to either write technical content through a Community Content Program for us for a $200 fee, or to donate that amount to charity.

  • How we use analytics as a privacy focused OSS company
    TLDR: Privacy is really important for us at Unleash. Here you will find the full story on how we ended up with an analytics solution that does not collect personal data and has very short retention. Whenever we evaluate a new feature at Unleash, we always start with one question. How does this fit with our values? This question is powerful. It can quickly qualify or disqualify a feature from consideration, putting... - Source: dev.to / almost 3 years ago

  • 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 / about 1 month 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 / 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.

  • 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 / 7 months ago
