Elm Task Port Example
As discussed on Elm-Discuss, it would be useful to be able to define Elm port interactions as tasks.
This project is an example implementation of such a proposal. It consists of three parts:
- A modified version of the elm-compiler GitHub repo, on the feature branch "feature/task-ports"
- A modified version of the elm-core library GitHub repo, on the feature branch "feature/task-ports"
- An example application (in this repo) showing usage of the new feature, and a compiled version of the example application
Running the (pre-compiled) example app
git clone this repository, and open the index.html file (possibly via a local web server).
Trying out things for yourself
Read the instructions to set up the Elm Platform for development.
Run the master branch build, like elm-platform describes: runhaskell BuildFromSource.hs master
It will clone the official git repositories of the compiler, elm-make, elm-reactor etc.
Go into the elm-compiler directory, do a git pull from the feature/task-ports branch to get the modified compiler.
Run runhaskell BuildFromSource.hs master again. The compiler should now have the task port feature, and the example
app should compile.
The Elm runtime must also be updated to use the modified version. In order to do this, go into the example project,
in the elm-stuff folder, replace the source of the core package with the contents of the feature/task-ports branch.
Delete the build-artifacts folder if it's present.
Run elm-make again on the project, and it should work!
