Only functions that are used in the script are returned.
Example:
int main(int argc, char* argv[])
{
Interpreter ir;
ir.addFunction("summ", [](const vector<string>& args) ->string {
int res = 0;
for (auto& v : args) {
if (isNumber(v)) res += stoi(v);
}
return to_string(res);
});
ir.addFunction("switch", [](const vector<string>& args) ->string {
if (!args.empty()) {
string key = args[0];
for (size_t i = 1; i < args.size(); ++i) {
if (key == args[i]) {
return "1";
}
}
}
return "0";
});
ir.addFunction("print", [](const vector<string>& args) ->string {
for (auto& v : args) {
printf("%s\n", v.c_str());
}
return "";
});
ir.addFunction("help", [&ir](const vector<string>& args) -> string
{
std::string result = "Available Functions: ";
for (auto& a : ir.allEntities()) {
if (a.type == Interpreter::EntityType::FUNCTION) {
result += a.name + ",";
}
}
result.pop_back();
return result;
});
string scenar = "$a; $b; summ($b, $a); switch($a, 5); help();";
string res = ir.cmd(scenar); // summ,switch,help
return 0;
}
