C++ (Cpp) OptTable::getOptionName Examples

Example #1

File: OptTable.cpp Project: My-Source/root

static std::string getOptionHelpName(const OptTable &Opts, OptSpecifier Id) {
  std::string Name = Opts.getOptionName(Id);

  // Add metavar, if used.
  switch (Opts.getOptionKind(Id)) {
  case Option::GroupClass: case Option::InputClass: case Option::UnknownClass:
    llvm_unreachable("Invalid option with help text.");

  case Option::MultiArgClass:
    llvm_unreachable("Cannot print metavar for this kind of option.");

  case Option::FlagClass:
    break;

  case Option::SeparateClass: case Option::JoinedOrSeparateClass:
    Name += ' ';
    // FALLTHROUGH
  case Option::JoinedClass: case Option::CommaJoinedClass:
  case Option::JoinedAndSeparateClass:
    if (const char *MetaVarName = Opts.getOptionMetaVar(Id))
      Name += MetaVarName;
    else
      Name += "<value>";
    break;
  }

  return Name;
