Title: CC with namespaces
Post by: Alpha on July 31, 2012, 03:41:03 am

I have been doing some work with OpenCV, and noticed that code completion appears to fail when namespaces are used.
For example:

Code

cv::Mat myMat;
myMat. // CC works here

But:

Code

using namespace cv;
Mat myMat;
myMat. // CC fails to launch

Is this a known shortcoming of the parser?  Is there a setting somewhere that I am missing?
(Code::Blocks rev 8160, OpenCV 2.4.2, Windows XP and Vista)

Both of the code snippet works here, they give the same suggestion list.
OpenCV 2.1, C::B nightly build, WinXP.

You can help to debug it by enable the smartsense log message, see:
8.4 Debug Smart Sense log output (http://wiki.codeblocks.org/index.php?title=Code_Completion_Design#Debug_Smart_Sense_log_output)

Strange... I cannot seem to reproduce the behavior now.  I will post again if I figure out in what situations it used to occur.

(I wonder what I changed?!)

If the using namespace line is placed in a header file, code completion fails within source files including it (but not specifying the namespace themselves).

Also, these typedef's from opencv2/core/core.hpp are not picked up:

Code

/*!
  \typedef

  shorter aliases for the most popular cv::Point_<>, cv::Size_<> and cv::Rect_<> specializations
*/
typedef Point_<int> Point2i;
typedef Point2i Point;
typedef Size_<int> Size2i;
typedef Size2i Size;
typedef Rect_<int> Rect;
typedef Point_<float> Point2f;
typedef Point_<double> Point2d;
typedef Size_<float> Size2f;
typedef Point3_<int> Point3i;
typedef Point3_<float> Point3f;
typedef Point3_<double> Point3d;

I enabled it, and now there is a lot of output; but what do I do with the log?  Is there something specific I should be looking for?

For the things with the typedefs you can also use the cc_test tool - a project within the CC plugin's sources. Then post the log here. These typedefs actually should work. What are your settings in CC?
