TemplateVariableInfo

WARNING: The constructor of this provider is experimental and may go away at any time.

Encapsulates template variables, that is, variables that can be referenced by strings like $(VARIABLE) in BUILD files and expanded by ctx.expand_make_variables and implicitly in certain attributes of built-in rules.

TemplateVariableInfo can be created by calling its eponymous constructor with a string-to-string dict as an argument that specifies the variables provided.

Example: platform_common.TemplateVariableInfo({'FOO': 'bar'})

to_json

string TemplateVariableInfo.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 TemplateVariableInfo.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 a list of these types. Quotes and new lines in strings are escaped. 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"
#   }
# }

variables

dict TemplateVariableInfo.variables

Returns the make variables defined by this target as a dictionary with string keys and string values
