  "message": "maprule: an improved version of genrule() (#86)\n\nmaprule() is an improved version of\r\nnative.genrule(), with the following advantages:\r\n\r\n- Maprule can process source files in parallel,\r\n  creating separate actions for each of them.\r\n\r\n- Maprule does not require declaring all output\r\n  files. Instead you declare templates for the\r\n  output files yielded for each source. Therefore\r\n  N source files and M templates yield N*M\r\n  outputs.\r\n\r\n- Maprule supports both Bash and cmd.exe syntax\r\n  for its commands via the specialized rules\r\n  bash_maprule and cmd_maprule.\r\n\r\n- Maprule\u0027s cmd attribute does deliberately not\r\n  support $(location) expression nor Make\r\n  Variables, in order to avoid issues and\r\n  challenges with quoting. (In case of cmd.exe\r\n  passing empty arguments is impossible). These\r\n  paths can be passed as envvars instead.\r\n\r\n- Maprule\u0027s add_env attribute does support\r\n  $(location) expressions (and some extra\r\n  placeholders) and is the idiomatic way to pass\r\n  execpaths of labels in \"tools\" or \"srcs\" (the\r\n  shared sources available for all actions) to the\r\n  command.\r\n\r\nSee https://github.com/bazelbuild/bazel/issues/4319",
