// Utility to embed a file in C++ binary.
//
// Usage:
// 1) Generate C++ code to be included in a source file.
// $ ./path/to/artifacts/embed_file
// --input=/path/to/file
// --name=kVarName
// --output=/path/to/header
//
// 2) Include the generated file (/path/to/header) in cc file:
//
// #include "base/embedded_file.h"
//
// namespace {
// // The definition of kVarName, which was specified in --name flag in 1),
// // is included here (#include in anonymous namespace is recommended).
// #include "/path/to/header"
// }
//
// // In this translation unit, the file content can be retrieved by:
// absl::string_view data = LoadEmbeddedFile(kVarName);
#include "base/port.h"
#include "absl/strings/string_view.h"
namespace mozc {
// Stores a byte data of file and its file size. To create this structure, use
// embed_file.py. The first address of embedded file data is aligned at 64 bit
// boundary, so we can embed data that requires normal alignment (8, 16, etc.).
