If a translation file exists in a "translations" directory located in the same directory as the binary, it is used in priority (this can be useful when working on translations as you don't have to recompile the whole program all the time), and if no such file is found the embedded translation file is used (if it exists).

// 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);
