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.

DefaultInfo

DefaultInfo DefaultInfo(files=None, runfiles=None, data_runfiles=None, default_runfiles=None, executable=None)

The DefaultInfo constructor.

Parameters

Parameter	Description
files	depset 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.
runfiles	runfiles set of files acting as both the data_runfiles and default_runfiles.
data_runfiles	runfiles the files that are added to the runfiles of a target that depend on the rule via the data attribute.
default_runfiles	runfiles the files that are added to the runfiles of a target that depend on the rule via anything but the data attribute.
executable	File If this rule is marked executable or test, this is a File object representing the file that should be executed to run the target. By default it is the predeclared output ctx.outputs.executable.

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
# }
