A haskell_binary() rule represents a groups of Haskell sources and deps which build an executable.

Parameters​

  • name: name of the target
  • default_target_platform: specifies the default target platform, used when no platforms are specified on the command line
  • target_compatible_with: a list of constraints that are required to be satisfied for this target to be compatible with a configuration
  • compatible_with: a list of constraints that are required to be satisfied for this target to be compatible with a configuration
  • exec_compatible_with: a list of constraints that are required to be satisfied for this target to be compatible with an execution platform
  • visibility: a list of visibility patterns restricting what targets can depend on this one
  • within_view: a list of visibility patterns restricting what this target can depend on
  • metadata: a key-value map of metadata associated with this target
  • tests: a list of targets that provide tests for this one
  • modifiers: an array of modifiers associated with this target
  • compiler_flags: Flags to pass to the Haskell compiler when compiling this rule's sources.
  • deps: 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.
  • link_group_deps: Additional targets to traverse when building link groups, but which should not be direct dependencies of the main executable.
  • link_group_public_deps_label: Surface nodes with this label as "public" nodes in the main executable when linking with with link groups.
  • link_style: Determines whether to build and link this rule's dependencies statically or dynamically. Can be either static, static_pic or shared.
  • main: The main module serving as the entry point into the binary. If not specified, the compiler default is used.
  • platform_deps: 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: A list of Haskell sources to be built by this rule. The dictionary option is deprecated.
