Guida is a functional programming language that builds upon the solid foundation of Elm, offering backward compatibility with all existing Elm 0.19.1 projects.
Guida builds on the foundations of Elm, aiming to advance the future of functional programming. By translating Elm's compiler from Haskell to a self-hosted environment, Guida helps developers to build reliable, maintainable, and performant applications without leaving the language they love.
Continuity and Confidence (Version 0.x): Guida starts by ensuring full backward compatibility with Elm v0.19.1, allowing developers to migrate effortlessly and explore Guida with complete confidence.
This commitment to continuity means that this version will faithfully replicate not only the features and behaviors of Elm v0.19.1, but also any existing bugs and quirks. By doing so, we provide a stable and predictable environment for developers, ensuring that their existing Elm projects work exactly as expected when migrated to Guida.
Evolution and Innovation (Version 1.x and Beyond): As Guida evolves, we will introduce new features and improvements. This phase will foster a unified ecosystem that adapts to the needs of its users.
Core Principles:
- Backward Compatibility: Respect for existing Elm projects, ensuring a frictionless migration.
- Accessibility: Lowering barriers for developers by implementing Guida’s core in its own syntax.
Our ultimate goal is to create a language that inherits the best aspects of Elm while adapting and growing to meet the needs of its users.
Start by installing Node Version Manager.
Switch to the correct node version number by running:
nvm use
Install the dependencies:
npm install
Generate guida:
npm run build
Link the project to run guida command:
npm link
You should now be able to run guida:
guida --help
To run an example cd into the examples folder, and run the guida make command:
cd examples
guida make --debug src/Hello.elm
You can then open index.html.
To clear all cache and re-generate ./bin/guida.js run the following:
rm -rf ~/.guida guida-stuff; npm run build
Run all tests:
npm test
Run jest tests:
npm test:jest
Run elm-test tests:
npm run test:elm
Run elm-review tests:
npm run test:elm-review
Run elm-format validation:
npm run test:elm-format-validate
npm run elm-format
- Initial transpilation from Haskell to Elm done based on Elm compiler v0.19.1 (more specifically commit c9aefb6)
- Terminal logic implementation based on https://github.com/albertdahlin/elm-posix
