| 5 # This file is meant to be included into a target to provide a rule | |
| 6 # to invoke protoc in a consistent manner. This is only to be included | |
| 7 # for Java targets. When including this file, a .jar-file will be generated. | |
| 8 # For other targets, see protoc.gypi. | |
| 9 # | |
| 10 # To use this, create a gyp target with the following form: | |
| 11 # { | |
| 12 # 'target_name': 'my_proto_lib', | |
| 13 # 'sources': [ | |
| 14 # 'foo.proto', | |
| 15 # 'bar.proto', | |
| 16 # ], | |
| 17 # 'variables': { | |
| 18 # 'proto_in_dir': '.' | |
| 19 # }, | |
| 20 # 'includes': ['path/to/this/gypi/file'], | |
| 21 # } | |
| 22 # | |
| 23 # The 'proto_in_dir' variable must be the relative path to the | |
| 24 # directory containing the .proto files. If left out, it defaults to '.'. | |
| 25 # | |
| 26 # The 'output_java_files' variable specifies a list of output files that will | |
| 27 # be generated. It is based on the package and java_outer_classname fields in | |
| 28 # the proto. All the values must be prefixed with >(java_out_dir), since that | |
| 29 # is the root directory of all the output. | |
| 30 # | |
| 31 # Implementation notes: | |
| 32 # A target_name of foo and proto-specified 'package' java.package.path produces: | |
| 33 # <(PRODUCT_DIR)/java_proto/foo/{java/package/path/}{Foo,Bar}.java | |
| 34 # where Foo and Bar are taken from 'java_outer_classname' of the protos. | |
| 35 # | |
| 36 # How the .jar-file is created is different than how protoc is used for other | |
| 37 # targets, and as such, this lives in its own file. | |
