Hpack.Dhall

Description

The functions in this module make it possible to configure an hpack package description with Dhall instead of YAML. When doing so, note that all functions resolve imports relative to the location of the given .dhall input file.

Synopsis

fileToJson :: FilePath -> IO (Either String ([String], Value))
showJson :: Maybe (Text -> Text -> Ordering) -> FilePath -> IO String
showYaml :: Maybe (Text -> Text -> Ordering) -> FilePath -> IO String
showDhall :: FilePath -> IO String
packageConfig :: FilePath

Documentation

fileToJson #

Arguments

:: FilePath	Path to a `.dhall` file
-> IO (Either String ([String], Value))

A file decoder for hpack. This should evaluate to a single record with hpack's top-level fields.

showJson #

Arguments

:: Maybe (Text -> Text -> Ordering)	An ordering of JSON fields.
-> FilePath	Path to a `.dhall` file
-> IO String

Pretty prints JSON for the package description.

showYaml #

Arguments

:: Maybe (Text -> Text -> Ordering)	An ordering of YAML fields.
-> FilePath	Path to a `.dhall` file
-> IO String

Pretty prints YAML for the package description.

showDhall #

Arguments

:: FilePath	Path to a `.dhall` file
-> IO String

Pretty prints the package description Dhall expression, resolving imports relative to the location of the .dhall file.

packageConfig :: FilePath #

The default package file name is package.dhall.
