DefaultInfo

A provider that gives general information about a target's direct and transitive files. Every rule type has this provider, even if it is not returned explicitly by the rule's implementation function.Each DefaultInfo instance has the following fields:
  • files
  • files_to_run
  • data_runfiles
  • default_runfiles
See the rules page for more information.

Members

data_runfiles

runfiles DefaultInfo.data_runfiles

the files that are added to the runfiles of a target that depend on the rule via the data attribute. May return None.

default_runfiles

runfiles DefaultInfo.default_runfiles

the files that are added to the runfiles of a target that depend on the rule via anything but the data attribute. May return None.

files

depset DefaultInfo.files

A depset of File objects representing the default outputs to build when this target is specified on the bazel command line. By default it is all predeclared outputs. May return None.

files_to_run

FilesToRunProvider DefaultInfo.files_to_run

A FilesToRunProvider object containing information about the executable and runfiles of the target. May return None.

to_json

string DefaultInfo.to_json()

Creates a JSON string from the struct parameter. This method only works if all struct elements (recursively) are strings, ints, booleans, other structs, a list of these types or a dictionary with string keys and values of these types. Quotes and new lines in strings are escaped. Examples:
struct(key=123).to_json()
# {"key":123}

struct(key=True).to_json()
# {"key":true}

struct(key=[1, 2, 3]).to_json()
# {"key":[1,2,3]}

struct(key='text').to_json()
# {"key":"text"}

struct(key=struct(inner_key='text')).to_json()
# {"key":{"inner_key":"text"}}

struct(key=[struct(inner_key=1), struct(inner_key=2)]).to_json()
# {"key":[{"inner_key":1},{"inner_key":2}]}

struct(key=struct(inner_key=struct(inner_inner_key='text'))).to_json()
# {"key":{"inner_key":{"inner_inner_key":"text"}}}

to_proto

string DefaultInfo.to_proto()

Creates a text message from the struct parameter. This method only works if all struct elements (recursively) are strings, ints, booleans, other structs or dicts or lists of these types. Quotes and new lines in strings are escaped. Struct keys are iterated in the sorted order. Examples:
struct(key=123).to_proto()
# key: 123

struct(key=True).to_proto()
# key: true

struct(key=[1, 2, 3]).to_proto()
# key: 1
# key: 2
# key: 3

struct(key='text').to_proto()
# key: "text"

struct(key=struct(inner_key='text')).to_proto()
# key {
#   inner_key: "text"
# }

struct(key=[struct(inner_key=1), struct(inner_key=2)]).to_proto()
# key {
#   inner_key: 1
# }
# key {
#   inner_key: 2
# }

struct(key=struct(inner_key=struct(inner_inner_key='text'))).to_proto()
# key {
#    inner_key {
#     inner_inner_key: "text"
#   }
# }

struct(foo={4: 3, 2: 1}).to_proto()
# foo: {
#   key: 4
#   value: 3
# }
# foo: {
#   key: 2
#   value: 1
# }
