Using title formatting (precompiling scripts, console output)

Hello,
more questions.

Can't seem to understand how title formatting is done.

Here's my attempt which I made from various posts I found on this forum.

My code:
Code: [Select]
#include "SDK\foobar2000.h"

DECLARE_COMPONENT_VERSION("foo_test","1.777","blah")

const GUID myguid = { 0x000F0001, 0x3300, 0x3452, { 0x00, 0x00, 0x12, 0x10, 0xAF, 0x00, 0x45, 0xFF } };

void context_click( const pfc::list_base_const_t<metadb_handle_ptr> & p_data )
{
    service_ptr_t<titleformat_object> g_to_global;
    service_ptr_t<titleformat_compiler> compiler;
    compiler->compile_safe(g_to_global,"%artist%");
    for (int i=0;i<p_data.get_count();i++){
        pfc::string8 out;
        p_data.get_item(i)->format_title(NULL,out,compiler,NULL);
        console::print(out.get_ptr());
    }

    return;
}


class entry: public initquit
{
public:
    virtual void on_init()
    {
        console::print("plugin started");
    }
    virtual void on_quit(){}
};

DECLARE_CONTEXT_MENU_ITEM (item_test,
                            "Copy artist name",
                            "foo_test", 
                            context_click, 
                            myguid, 
                            "Copy artists") 

static initquit_factory_t<entry> myinstance;


Thanks

Full-quoting makes you scroll past the same junk over and over.

I actually tried that first, but the compiler throws me:

error C2664: 'metadb_handle::format_title' : cannot convert parameter 3 from 'static_api_ptr_t<t_interface>' to 'const service_ptr_t<T> &'

So I thought I needed to use the service_ptr_t template instead.

You need to pass the compiled script to metadb_handle::format_title(), not the compiler.
Also, it is recommendable to pre-allocate and reuse the output string.

Code: [Select]
titleformat_object::ptr script;
static_api_ptr_t<titleformat_compiler>()->compile_safe(script, "%artist%");
pfc::string8_fast_aggressive buffer;
buffer.prealloc(128);
console::formatter out;
for (t_size i = 0, n = p_data.get_count(); i < n; ++i) {
    if (p_data[i]->format_title(NULL, buffer, script, NULL)) {
        out << buffer.get_ptr() << "\n";
    }
}
