Input:

stack new sample

Output:

Downloading template new-template to create project sample in directory sample\...
C:\UC:\UDownloaded C:\Users\むずでょ\AppData\Roaming\stack\templates\new-template.hsfiles.

Note: The following parameters were needed by the template but not provided: author-email, author-name, category, copyright and github-username.

      You can provide them in Stack's global YAML configuration file (C:\Users\むずでょ\AppData\Roaming\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 on the command line as parameters like this:

      stack new sample new-template -p "author-email:value" -p "author-name:value" -p "category:value" -p "copyright:value" -p "github-username:value"

# Resolver to choose a 'specific' stackage snapshot or a compiler version.
# A snapshot resolver dictates the compiler version and the set of packages
# to be used for project dependencies. For example:
#
# resolver: lts-3.5
# resolver: nightly-2015-09-21
# resolver: ghc-7.10.2
#
# The location of a snapshot can be provided as a file or url. Stack assumes
# a snapshot provided as a file might change, whereas a url resource does not.
#
# resolver: ./custom-snapshot.yaml
# resolver: https://example.com/snapshots/2018-01-01.yaml
resolver:
  url: https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/lts/20/8.yaml

# User packages to be built.
# Various formats can be used as shown in the example below.
#
# packages:
# - some-directory
# - https://example.com/foo/bar/baz-0.0.2.tar.gz
#   subdirs:
#   - auto-update
#   - wai
packages:
- .
# Dependency packages to be pulled from upstream that are not in the resolver.
# These entries can reference officially published versions as well as
# forks / in-progress versions pinned to a git hash. For example:
#
# extra-deps:
# - acme-missiles-0.3
# - git: https://github.com/commercialhaskell/stack.git
#   commit: e7b331f14bcffb8367cd58fbfc8b40ec7642100a

# extra-deps: []

# Override default flag values for local packages and extra-deps
# flags: {}

# Extra package databases containing global packages
# extra-package-dbs: []

# Control whether we use the GHC we find on the path
# system-ghc: true
#
# Require a specific version of Stack, using version ranges
# require-stack-version: -any # Default
# require-stack-version: ">=2.9"
#
# Override the architecture used by Stack, especially useful on Windows
# arch: i386

#
# Extra directories used by Stack for building
# extra-include-dirs: [/path/to/dir]
# extra-lib-dirs: [/path/to/dir]
