Re: [Cppcms-users] How to set default response().out() stream precision?

[Artyom B. <art...@ya...>]

See changing defaults is very bad idea - especially at framework level.

If you have some trouble in all over the code, that seems that you
had some **design** problem at the beginning and you try to solve it by
altering the framework itself.

The correct way to solve it is to set the precision on template
level where you need:

  <% gt "{1,precision =10}" using my_high_precision_value %>


See: http://www.boost.org/doc/libs/1_49_0/libs/locale/doc/html/localized_text_formatting.html

If you need to change it globally create a small function in you topmost application
class that all your classes are derived from:

   void render(std::string const &template_name,cppcms::basi_context &c)
   {
         response().out() << std::setprecision(10);
         cppcms::application::render(template_name,c);
   }

Or even better create render_with_high_precision(...) function
and do small refactoring.
