Generate scaffold for a Haskell project


This application generates a scaffold for Haskell project from a Git repository. The template can be specified by Git repository. hi-hspec will be used as a default template.


Basic Example

$ hi foo-bar-baz
Creating new project with git repository:git://
    create  foo-bar-baz/.gitignore
    create  foo-bar-baz/LICENSE
    create  foo-bar-baz/
    create  foo-bar-baz/foo-bar-baz.cabal
    create  foo-bar-baz/src/Foo/Bar/Baz.hs
    create  foo-bar-baz/src/Foo/Bar/Baz/Internal.hs
    create  foo-bar-baz/test/Foo/Bar/BazSpec.hs
    create  foo-bar-baz/test/Spec.hs

Specifying template

Specifying repository in GitHub has a shorthand like this:

$ hi foo-bar-baz --repository gh:fujimura/hi-flat
Creating new project from repository: [email protected]:fujimura/hi-flat.git
    create  foo-bar-baz/.gitignore
    create  foo-bar-baz/LICENSE
    create  foo-bar-baz/Main.hs
    create  foo-bar-baz/Foo/Bar/Baz.hs
    create  foo-bar-baz/
    create  foo-bar-baz/foo-bar-baz.cabal


  -h,--help                Show this help text
  -v,--version             Print version information
  -p,--package-name ARG    Name of package
  -m,--moduleName ARG      Name of Module
  -a,--author ARG          Name of the project's author
  -e,--email ARG           Email address of the maintainer
  -r,--repository ARG      Template repository
  --configuration-file ARG Use specified configuration file
                           Initialize with git repository
  --after-command ARG      The command to be run after generation

How to make your own template

Template is used for templating.

Available variables:

  • $packageName
    : name of package, like 'hi'
  • $moduleName
    : name of module, like 'Hi'
  • $author
    : name of author, like 'Fujimura Daisuke'
  • $email
    : email address of maintainer, like '[email protected]'

'package-name' and 'ModuleName' in filepath will be replaced with given variable.

Files under

will be used as the source of generated files. Files in root directory will not be copied.


I'm tired to organize directory structure for every new Haskell project which has some test. This library is heavily inspired by grunt-init.
