Convert between pointfree and pointful expressions.

Latest on Hackage:1.0.2

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow to host generated Haddocks.

Blunt is a web front end to the pointfree and pointful libraries. While you can install and run it locally, there’s no real reason to prefer it over the pointfree and pointful executables. Instead, use the hosted version:


$ cabal update
$ cabal install 'blunt ==1.*'


$ blunt
# http://localhost:8080

$ env PORT=8888 blunt
# http://localhost:8888


$ git clone
$ cd blunt

$ cabal sandbox init
$ cabal install happy
$ cabal install --only-dependencies
$ cabal run
# http://localhost:8080


# Create a new app on Heroku using the Haskell on Heroku buildpack.
$ heroku apps:create --buildpack

# Let Halcyon know that we need happy installed.
$ heroku config:set HALCYON_SANDBOX_EXTRA_APPS='happy'

# Configure AWS S3.
$ heroku config:set HALCYON_AWS_ACCESS_KEY_ID='...'
$ heroku config:set HALCYON_AWS_SECRET_ACCESS_KEY='...'
$ heroku config:set HALCYON_S3_BUCKET='...'

# Push the code up to Heroku. Note that this build is expected to fail.
$ git push heroku master

# Build the app on a PX dyno.
$ heroku run --size PX build

# Force Heroku to rebuild the app using the cache built in the last step.
$ git commit --amend --no-edit
$ git push --force heroku master

# Scale up a web dyno to serve requests.
$ heroku ps:scale web=1
