}| | | }| |r| S |S )a Convert protobuf message to text format.
Double values can be formatted compactly with 15 digits of
precision (which is the most that IEEE 754 "double" can guarantee)
using double_format='.15g'. To ensure that converting to text and back to a
proto will result in an identical value, double_format='.17g' should be used.
Args:
message: The protocol buffers message.
as_utf8: Return unescaped Unicode for non-ASCII characters.
as_one_line: Don't introduce newlines between fields.
use_short_repeated_primitives: Use short repeated format for primitives.
pointy_brackets: If True, use angle brackets instead of curly braces for
nesting.
use_index_order: If True, fields of a proto message will be printed using
the order defined in source code instead of the field number, extensions
will be printed at the end of the message and their relative order is
determined by the extension number. By default, use the field number
order.
float_format (str): If set, use this to specify float field formatting
(per the "Format Specification Mini-Language"); otherwise, shortest float
that has same value in wire will be printed. Also affect double field
if double_format is not set but float_format is set.
double_format (str): If set, use this to specify double field formatting
(per the "Format Specification Mini-Language"); if it is not set but
float_format is set, use float_format. Otherwise, use ``str()``
use_field_number: If True, print field numbers instead of names.
descriptor_pool (DescriptorPool): Descriptor pool used to resolve Any types.
indent (int): The initial indent level, in terms of spaces, for pretty
print.
message_formatter (function(message, indent, as_one_line) -> unicode|None):
Custom formatter for selected sub-messages (usually based on message
type). Use to pretty print parts of the protobuf for easier diffing.
print_unknown_fields: If True, unknown fields will be printed.
force_colon: If set, a colon will be added after the field name even if the
field is a proto message.
Returns:
str: A string of the text formatted protocol buffer message.

NOTE: for historical reasons this function does not clear the input
message. This is different from what the binary msg.ParseFrom(...) does.
If text contains a field already set in message, the value is appended if the
field is repeated. Otherwise, an error is raised.
Example::
a = MyProto()
a.repeated_field.append('test')
b = MyProto()
# Repeated fields are combined
text_format.Parse(repr(a), b)
text_format.Parse(repr(a), b) # repeated_field contains ["test", "test"]
# Non-repeated fields cannot be overwritten
a.singular_field = 1
b.singular_field = 2
text_format.Parse(repr(a), b) # ParseError
# Binary version:
b.ParseFromString(a.SerializeToString()) # repeated_field is now "test"
Caller is responsible for clearing the message as needed.
Args:
text (str): Message text representation.
message (Message): A protocol buffer message to merge into.
allow_unknown_extension: if True, skip over missing extensions and keep
parsing
allow_field_number: if True, both field number and field name are allowed.
descriptor_pool (DescriptorPool): Descriptor pool used to resolve Any types.
allow_unknown_field: if True, skip over unknown field and keep
parsing. Avoid to use this option if possible. It may hide some
errors (e.g. spelling error on field name)
Returns:
Message: The same message passed as argument.
