Using `streamly` package

Latest stable release is available on Hackage.
Latest development version is available on github.
See recommended compilation options here.

If you are using stack or nix please make sure to add the latest version from Hackage to your tool configuration.

Using with `cabal`

Make sure you have cabal version 3.0 or later installed and you have ghc available in your PATH. Refresh your package list:

$ cabal update

Using hackage version in repl

# Run repl with the latest version from Hackage
$ cabal repl --build-depends streamly

# Run repl with a specific version from Hackage
$ cabal repl --build-depends streamly==0.7.1

Using github version in repl

Create a directory for your playground (e.g. test) and create a cabal.project file in it as follows:

packages: .
source-repository-package
  type: git
  location: https://github.com/composewell/streamly
  tag: master

Create a cabal file (e.g. test.cabal) as follows

cabal-version: 2.4
name: test
version: 0

library
  build-depends: base, streamly

Run repl:

$ cabal repl

Using with ghc or ghci

Before you can use a package with ghc or ghci directly you need to install the package:

$ cabal install streamly-0.7.1 --lib

$ cat hello.hs
import qualified Streamly.Prelude as S

main = S.runStream $ S.fromListM [putStrLn "hello", putStrLn "world"]

$ ghc hello.hs

Using in a Project

Add streamly to the build-depends section of your library/executable in your <package>.cabal file. Appropriate version from Hackage will be picked depending on the version bounds that you specify. See the github version in repl section above for a sample <package>.cabal file and optionally use the cabal.project file if you want to use the development version from github in your project.
