printing blitz arrays via GDB

[kishore1947]

We would like your inputs on a couple of queries related to blitz usage.
It is very useful that Blitz supports printing any multidimensional arrays with a very simple statement as below
std::cout<<blitz_array_name<<std::endl

We are working on a large codebase, and we would like to print the array contents during the debug sessions as well.
We use GDB for debugging. We tried an option as below

a) overloaded functions for different type of arrays which we like to print, as below

void printBlitz(blitz::Array<bool, 1> &in)
{
std::cout<<in<<std::endl;
}

void printBlitz(blitz::Array<int, 1> &in)
{
std::cout<<in<<std::endl;
}

and so on
on the gdb debugger, we can simply call this function as below

(gdb) call printBlitz(blitz_array_name)

The issue now is we use many types of multi-dimensional arrays (including complex), we have to make overloads for every possible array

If you have any suggestions to directly print the blitz contents via GDB, please let us know.

This will simplify our debug to a large extent.
Any suggestion is highly appreciated

Thank you so much in advance !!

Would the use of templates address your problem?

Hi, Thanks a lot for the response ! I tried doing this but no luck, also it is not very straight forward to call template functions via GDB, but is still ok. Could you please help provide an example with the same code as I gave, by writing a template function to print a blitz array Thanks a lot ! Thanks and Best Regards, Kishore On Sun, May 10, 2020 at 2:05 PM Elizabeth Fischer <[email protected]> wrote:
