Defining and Using a Symbol Analogue for Error Reporting in C++

Abstract

The use of exceptions isn't a viable error handling approach in all cases and returning codes for error handling is sometimes preferable. However, using integral types for error identification is problematic as there is no good mechanism to guarantee that each value uniquely

using bfs = boost::filesystem;

void recursive_copy(const bfs::path &src, const bfs::path &dst)
{
  if (bfs::exists(dst)){
    throw std::runtime_error(dst.generic_string() + " exists");
  }

  if (bfs::is_directory(src)) {
    bfs::create_directories(dst);

This is the example that comes with the reagent template converted to use HTML5 based history. This means there are no # in the urls.

I just got this working, so there might be better approaches

The changes are

• use goog.history.Html5history instead of goog.History
• listen to clicks on the page, extract the path from them, and push them onto the history
• listen to history changes, and have secretary do its thing in response
