// This program takes a list of files as an input, and produces C++ code that
|
||||
// contains the contents of all these files as a collection of strings.
|
||||
//
|
||||
// Usage:
|
||||
// 1. Compile this file:
|
||||
// cc -o generate-translations-header generate-translations-header.c
|
||||
//
|
||||
// 2. Convert list of files into single header:
|
||||
// ./generate-translations-header monero_fr.qm monero_it.qm > translations_files.h
|
||||
//
|
||||
// 3. In your application code, include translations_files.h, then you can
|
||||
// access the files using this function:
|
||||
// static bool find_embedded_file(const std::string &file_name, std::string &data);
|
||||
// std::string data;
|
||||
// find_embedded_file("monero_fr.qm", data);
