4 5 // Package text implements the text format for protocol buffers.
6 // This package has no semantic understanding for protocol buffers and is only
7 // a parser and composer for the format.
8 //
9 // There is no formal specification for the protobuf text format, as such the
10 // C++ implementation (see google::protobuf::TextFormat) is the reference
11 // implementation of the text format.
12 //
13 // This package is neither a superset nor a subset of the C++ implementation.
14 // This implementation permits a more liberal grammar in some cases to be
15 // backwards compatible with the historical Go implementation.
16 // Future parsings unique to Go should not be added.
17 // Some grammars allowed by the C++ implementation are deliberately
18 // not implemented here because they are considered a bug by the protobuf team
19 // and should not be replicated.
20 //
21 // The Go implementation should implement a sufficient amount of the C++
22 // grammar such that the default text serialization by C++ can be parsed by Go.
23 // However, just because the C++ parser accepts some input does not mean that
24 // the Go implementation should as well.
25 //
26 // The text format is almost a superset of JSON except:
27 // - message keys are not quoted strings, but identifiers
28 // - the top-level value must be a message without the delimiters
