#include "CommandLineInterface.h"

#include <clocale>

#include <iostream>

#include <boost/exception/all.hpp>

using namespace std;

The equivalent of setlocale(LC_ALL, "C") is called before any user code is run.

If the user has an invalid environment setting then it is possible for the call

to set locale to fail, so there are only two possible actions, the first is to

throw a runtime exception and cause the program to quit (default behaviour),

or the second is to modify the environment to something sensible (least

surprising behaviour).

The follow code produces the least surprising behaviour. It will use the user

specified default locale if it is valid, and if not then it will modify the

environment the process is running in to use a sensible default. This also means

that users do not need to install language packs for their OS.

static void setDefaultOrCLocale()

{

#if __unix__

if (!std::setlocale(LC_ALL, ""))

{

setenv("LC_ALL", "C", 1);

}

#endif

}

int main(int argc, char** argv)

{

setDefaultOrCLocale();

dev::solidity::CommandLineInterface cli;

if (!cli.parseArguments(argc, argv))

return 1;

if (!cli.processInput())

return 1;

bool success = false;

try

{

success = cli.actOnInput();

}

catch (boost::exception const& _exception)

{

cerr << "Exception during output generation: " << boost::diagnostic_information(_exception) << endl;

success = false;

}

return success ? 0 : 1;

}
