haskell-ci - CI generator for multiple GHC versions

At the moment haskell-ci support GitHub Actions workflow generation. There is also legacy Travis-CI configuration generator, which is unmaintained.

haskell-ci relies on hvr-ppa or ghcup to install GHC and cabal-install.

Quick-start instructions

• Step 1: Clone and install this project in/from any directory

  $ git clone https://github.com/haskell-CI/haskell-ci.git
  $ cd haskell-ci
  $ cabal install haskell-ci:exe:haskell-ci
  

  or

  cabal install haskell-ci
  

• Step 2: Change directories to your project:

  $ cd path/to/your-project
  

• Step 3: Edit your project's *.cabal file to add a tested-with line, such as this one:

  $ cat your-project.cabal
  ...
  tested-with: GHC ==9.6.3 || ==9.4.8 || ==9.2.8
  ...
  

  Add as many or as few GHC versions to test as you want.

• Step 4: Generate a workflow file for your project:

  $ # You run the following command from your project's directory, even
  $ # though it references the script from the `haskell-ci` project
  $ haskell-ci github your-project.cabal
  

  Note: If you have multiple local Cabal projects that you wish to build together using a cabal.project file, pass that file to haskell-ci instead:

  $ haskell-ci github cabal.project
  

  The haskell-ci tool looks at the Tested-With line in your *.cabal files and generates a configuration that tests each compiler version you listed in parallel.

• Step 5: Create a pull request with your new CI configuration.

  ... or push directly to your main branch if you feel lucky.

  Sometimes you may need to regenerate CI script, for example, when adding new compiler version to tested-with. You may simply run haskell-ci regenerate.
