Redefinition of function with namespace

[Huichu Zhang]

Hi, in cling 0.7.0, function redefinition is supported, which is great!
I can run the following cell and redefine function as many time as I want

int test(int x) {
    return x+2;
}

However, if I specify namespace, an error will occur

namespace myname {
    int test(int x) {
        return x+2;
    }
}

input_line_14:2:9: error: redefinition of 'test'
    int test(int x) {
        ^
input_line_13:2:9: note: previous definition is here
    int test(int x) {
        ^

Is there a way to work around this?

Also, I want to redefine system function like

void system(const std::string &cmd) {
    std::cout << "system: " << cmd << std::endl;
}

However, when I call system("123"), I still get the original system function.

Hello @zhc134,

Providing a new definition for a namespace member is not currently supported. In regards to redefining the system() function, we are currently working on allowing this, but it still has some caveats. I will leave this issue open until it completely works.

Cheers,
J.

Works fine with current master. Please reopen if it still fails.

int test(int x) { return x+1; }
namespace myname { int test(int x) { return x+2; } }
test(1)
(int) 2
myname::test(1)
(int) 3

Also, I want to redefine system function like

Works fine with latest master if you choose the right signature:

extern int system( const char* command ) { std::cout << "system: " << std::endl; return 1; }
system("123");
system:
