github-actions-dhall
This is a demonstration using Dhall to generate YAML for github actions.
github-actions-dhall is self-hosting.
Example
Haskell
Store the following in example.dhall:
let haskellCi = https://raw.githubusercontent.com/vmchale/github-actions-dhall/master/haskell-ci.dhall
in haskellCi.generalCi
haskellCi.matrixSteps
( Some
{ ghc =
[ haskellCi.GHC.GHC8101
, haskellCi.GHC.GHC883
, haskellCi.GHC.GHC865
]
, cabal = [ haskellCi.Cabal.Cabal32 ]
}
)
: haskellCi.CI.TypeThen, generate YAML with dhall-to-yaml --file example.dhall
