Search tips

apple banana
Find rows that contain at least one of the two words.

+apple +juice
Find rows that contain both words.

+apple macintosh
Find rows that contain the word 'apple', but rank rows higher if they also contain 'macintosh'.

+apple -macintosh
Find rows that contain the word 'apple' but not 'macintosh'.

+apple ~macintosh
Find rows that contain the word 'apple', but if the row also contains the word 'macintosh', rate it lower than if row does not. This is "softer" than a search for '+apple -macintosh', for which the presence of 'macintosh' causes the row not to be returned at all.

+apple +(>turnover >strudel)
Find rows that contain the words 'apple' and 'turnover', or 'apple' and 'strudel' (in any order), but rank 'apple turnover' higher than 'apple strudel'.

apple*
Find rows that contain words such as 'apple', 'apples', 'applesauce', or 'applet'.

"some words"
Find rows that contain the exact phrase 'some words' (for example, rows that contain 'some words of wisdom' but not "some noise words").

VectorCAST C++ 14 Support for Variable Templates

Last updated: 2019-10-02

C++ 14 Variable Templates in VectorCAST 2018 SP3 now has support for:

  1. Environments with source code containing non-const template variables.
  2. Template variables in the Parameter Tree with template parameters.
  3. Importing Template variables in test scripts (.tst).

Example code for Variable Templates:

#include <type_traits>
#include <string>

struct WantName {};
struct WantDir {};

template <typename Tag, typename ... Tags>
const std::string config_data = config_data<Tag> + '\n' + config_data<Tags...>;

template <>
const std::string config_data<WantName> = "Name: grep";

template <>
const std::string config_data<WantDir> = "Directory: /usr/bin/";

std::string templated_variables_test(int n) {
  std::string ret;
  if(n > 0) {
    ret = config_data<WantDir, WantName>;
  }
  else if(n == 0) {
    ret = config_data<WantDir>;
  }
  else {
    ret = config_data<WantName>;
  }
  return ret;
}
