Hi,
Apologies if this is the wrong forum for this question - redirection to the correct place would be appreciated…
I am running
lldb --version
lldb-900.0.64
Swift-4.0
with binaries compiled using g++
g+±5 --version
g+±5 (Homebrew GCC 5.5.0_2) 5.5.0

The website implies that gcc std library formatters should be available:
By default, several categories are created in LLDB:
-
default: this is the category where every formatter ends up, unless another category is specified -
objc: formatters for basic and common Objective-C types that do not specifically depend on Mac OS X -
gnu-libstdc++: formatters for std::string, std::vector, std::list and std::map as implemented by libstdcpp
However I see:
(lldb) type category list Category: default (enabled)
Category: VectorTypes (enabled, applicable for language(s): objective-c++)
Category: runtime-synthetics (enabled, applicable for language(s): objective-c++, swift)
Category: system (enabled, applicable for language(s): objective-c++)
(lldb) type category enable gnu-libstdc++ warning: empty category enabled (typo?)
And the std containers do not print nicely:
containerTest: cat main.cpp
#include
#include
using namespace std;
int main()
{
auto v = vector< unsigned >{ 0, 1, 2, 3, 4, 5, 6, 7, 9 };
for( auto i : v )
{
cout << i << “\n”;
}
return( 0 );
}

Anyone able to point me at either a python pretty printer or solution to this?
Cheers, Bryan.
