  <h1>site-C-ing compile-time exception handling</h1>
  <p>
   Similar to <a href="/exceptions/preprocess">preprocessing exceptions</a>
   there is a wide range of errors you may put into your code which will pass
   through preprocessor and will be caught later at the compile-time.
  </p>
  <p>
   Once you complete writing your <a
   href="/view/htdocs/exceptions/development/compile.chtml" target="insert"
   title="the link opens in the frame below">erroneous code</a> and
   <em>site-C-ing</em> is done preprocessing it, it will feed the preprocessed
   code into c++ compiler which will refuse to compile the code like this. This
   is where <a href="/view/htdocs/handlers/exception_dev" target="insert"
   title="the link opens in the frame below">the exception handler</a>,
   specified in <a href="/view/htdocs/exceptions/development/.scrc"
   target="insert" title="the link opens in the frame below">the configuration
   file</a>, takes over the process and gives you <a
   href="/exceptions/development/compile" target="insert" title="the link opens
   in the frame below">the report</a>.  Like with any handler, you may wish to
   set some <a href="/view/htdocs/handlers/exception_prod" target="insert"
   title="the link opens in the frame below">different handler</a> in your <a
   href="/view/htdocs/exceptions/production/.scrc" target="insert" title="the
   link opens in the frame below">production configuration</a>, which just gives
   user <a href="/exceptions/production/preprocess" target="insert" title="the
   link opens in the frame below">a friendly yet lame excuse</a>.
  </p>
  <p class="note">
   Note, that these output pages are fakes -- I do not want to spawn the
   compiler each time you want to see the output and put this unnecessary load
   on cpu. These static pages are in fact saved output of the real exception
   handlers.

  <h1>site-C-ing exception handling</h1>
  <p>
   The purpose of this section is to give an overview of the <em>site-C-ing</em>
   exception handling mechanism. Before the web visitor can see the page each
   site-C-ing component goes through a few stages, namely, preprocessing,
   compiling and execution. Having three stages to go through also means the
   stages one can fail to go through and three exciting opportunities to handle
   different errors.
  </p>
  <p>
   First each component is preprocessed so that you can feed the valid c++ code
   to the compiler. Here is where the preprocessor can choke at your broken
   source code. Once preprocessor failes to parse your code it will throw an
   exception which <em>site-C-ing</em> will catch and pass to <a
   href="/sources/htdocs/handlers/exception_dev" title="development mode
   exception handler source">the exception handler component</a>. Want to <a
   href="/exceptions/preprocess">read more</a> about preprocessor exception
   handling?
  </p>
  <p>
   After the preprocessing stage is over we have a great opportunity to catch
   the compile-time errors. After <em>site-C-ing</em> fails to compile the
   component it throws another exception and passes it to the same handler which
   may show you some information on what's gone wrong with your source code from
   the compiler's perspective. If you've gone this far you definitely want to <a
   href="/exceptions/compile">read more</a> about the compiler error handling.
  </p>
  <p class="note">
   Note, that it is likely that you will want to disable the steps above for the
   production environment to save time on unnecessary checking whether the
   component is up to date.
  </p>
  <p>
   Finally, we need to execute the component and present its output to the web
   site visitor. This is also where things may go wrong and here is where your
   component may throw an exception for the engine to catch and pass to the
   handler. Feel free to <a href="/exceptions/runtime">learn more</a> about it
   as well.
  </p>
  <p class="note">
   One more thing you will likely want to have differently in production
   environment is <a href="/sources/htdocs/handlers/exception_prod"
   title="production mode exception handler source">an exception handler</a>
   which will not give out that much unnecessary information to the user.

  <h1>site-C-ing preprocessor exception handling</h1>

   It was one of those days when you just can't type right and can't think of
   what you're typing. It is not unusual that, under such circumstances, you end
   up with a code like <a
   href="/view/htdocs/exceptions/development/preprocess.chtml" target="insert"
   title="the link opens in the frame below">this</a> -- by the time you were
   about to close your <code>&lt;%code&gt;</code> block you were thinking about
   some constructor in some component elsewhere in the universe.
  </p>
  <p>
   <em>site-C-ing</em> parser will see the inconsistency and throw an exception
   which will be caught and passed to <a
   href="/view/htdocs/handlers/exception_dev" target="insert" title="the link

  <h1>site-C-ing runtime exception handling</h1>
  <p>
   The component may throw an exception while executing and the
   <em>site-C-ing</em> will gladly pass it to the handler component which will
   give the user appropriate output (unless it throws an exception itself, of
   course). Here you will see an example output provided by the handler bundled
   with the <em>site-C-ing</em>.
