#include <tts/tools/as_text.hpp>

Value-to-string conversion.

When displaying the data required to understand a test's failures, TTS may need to print out value of various types. as_text provides a centralized way to perform such a task by handling most common types including:

• pointers
• floating points
• integers
• sequences of such types

as_text takes care of applying any command-line options related to formatting to the value printed. For user defined types, an overload of a to_text function must be found via ADL.

Examples

#define TTS_MAIN // No need for main()
#include <tts/tts.hpp>
 
namespace space
{
  struct some_type
  {
    int i;
  };
 
  tts::text to_text(some_type const& s) { return "some_type[" + tts::as_text(s.i) + "]"; }
 
  struct some_other_type
  {
    int              j;
 
    friend tts::text to_text(some_other_type const& s) { return "[[" + tts::as_text(s.j) + "]]"; }
  };
}
 
TTS_CASE("Check display of type with specific to_text")
{
  TTS_EQUAL(tts::as_text(space::some_type {42}), "some_type[42]");
  TTS_EQUAL(tts::as_text(space::some_other_type {63}), "[[63]]");
};

Parameters

e	Value to convert to tts::text

Returns

An instance of tts::text containing a representation of the value of e
