What do I need to do to initialize a GHCJS project using Haskell Stack?
Following the glass documentation , I am trying to initialize a GHCJS project so that I can compile Haskell code for JavaScript.
After execution, stack templatesI see that there is a GHCJS template
ghcjs - Haskell to JavaScript compiler, based on GHC
When I try to use a new command with this template, for example:
stack new ghcjsSetup ghcjs
I get this error message:
Downloading template "ghcjs" to create project "ghcjsSetup" in ghcjsSetup/ ...
The following parameters were needed by the template but not provided: author-email, author-name, category, copyright, github-username
You can provide them in /home/u/.stack/config.yaml, like this:
templates:
params:
author-email: value
author-name: value
category: value
copyright: value
github-username: value
Or you can pass each one as parameters like this:
stack new ghcjsSetup ghcjs -p "author-email:value" -p "author-name:value" -p "category:value" -p "copyright:value" -p "github-username:value"
Looking for .cabal or package.yaml files to use to init the project.
Using cabal packages:
- ghcjsSetup/ghcjsSetup.cabal
