haskell_library

A haskell_library() rule is used to identity a group of Haskell sources.

Parameters

• name: (required)

  name of the target

• default_target_platform: (defaults to: None)

  specifies the default target platform, used when no platforms are specified on the command line

• target_compatible_with: (defaults to: [])

  a list of constraints that are required to be satisfied for this target to be compatible with a configuration

• compatible_with: (defaults to: [])

  a list of constraints that are required to be satisfied for this target to be compatible with a configuration

• exec_compatible_with: (defaults to: [])

  a list of constraints that are required to be satisfied for this target to be compatible with an execution platform

• visibility: (defaults to: [])

  a list of visibility patterns restricting what targets can depend on this one

• within_view: (defaults to: ["PUBLIC"])

  a list of visibility patterns restricting what this target can depend on

• metadata: (defaults to: {})

  a key-value map of metadata associated with this target

• tests: (defaults to: [])

  a list of targets that provide tests for this one

• modifiers: (defaults to: [])

  an array of modifiers associated with this target

• compiler_flags: (defaults to: [])

  Flags to pass to the Haskell compiler when compiling this rule's sources.

• deps: (defaults to: [])

  Either haskell_library() or prebuilt_haskell_library() rules from which this rules sources import modules or native linkable rules exporting symbols this rules sources call into.

• platform_deps: (defaults to: [])

  Platform specific dependencies. These should be specified as a list of pairs where the first element is an un-anchored regex (in java.util.regex.Pattern syntax) against which the platform name is matched, and the second element is a list of dependencies (same format as deps) that are exported if the platform matches the regex. See deps for more information.

• srcs: (defaults to: [])

  A list of Haskell sources to be built by this rule. The dictionary option is deprecated.

Examples

haskell_library(
  name = 'fileutil',
  srcs = [
    'FileUtil.hs',
  ],
)
