GNU gettext is a popular solution in free/open source software world to do i18n/l10n of software, by providing translated strings that will substitute strings in original language (typically, English).
gettext .mo is a binary database format which stores these string translation pairs in an efficient binary format, ready to be used by gettext-enabled software. .mo format is a result of compilation of text-based .po files using msgfmt utility. The reverse conversion (.mo -> .po) is also possible using msgunfmt decompiler utility.
This page hosts a formal specification of gettext binary database using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.
All parsing code for C++98/STL generated by Kaitai Struct depends on the C++/STL runtime library. You have to install it before you can parse data.
For C++, the easiest way is to clone the runtime library sources and build them along with your project.
Using Kaitai Struct in C++/STL usually consists of 3 steps.
std::istream
). One can open local file for that, or use existing std::string
or char*
buffer.
#include <fstream>
std::ifstream is("path/to/local/file.mo", std::ifstream::binary);
#include <sstream>
std::istringstream is(str);
#include <sstream>
const char buf[] = { ... };
std::string str(buf, sizeof buf);
std::istringstream is(str);
#include "kaitai/kaitaistream.h"
kaitai::kstream ks(&is);
gettext_mo_t data(&ks);
After that, one can get various attributes from the structure by invoking getter methods like:
data.signature() // => get signature
#ifndef GETTEXT_MO_H_
#define GETTEXT_MO_H_
// This is a generated file! Please edit source .ksy file and use kaitai-struct-compiler to rebuild
#include "kaitai/kaitaistruct.h"
#include <stdint.h>
#include <vector>
#if KAITAI_STRUCT_VERSION < 9000L
#error "Incompatible Kaitai Struct C++/STL API: version 0.9 or later is required"
