GetAuroraDir

[Parker]

In IBasic Pro, we could easily get the command paks location, helpfiles, whatever we wanted, since we had fletchie's GetIBProDir() function. That function enabled us to write command paks using his installer, and it worked by reading the BIN key under HKEY_CURRENT_USER\Software\Pyxia\IBasic Pro\PATHS. Since the Aurora IDE works in a similar way, we can read the BIN key of HKCU\Software\IonicWind\Aurora\PATHS and get the path to the 'bin' directory of Aurora. If you need any others, just chop off the part after the last '\' character and add to it.

This code includes an example of using the function.

// The key we need is under HKCU\Software\IonicWind\Aurora\PATHS -- it is called BIN.
unsigned int key, size=255, type;
string value;
RegOpenKeyEx(
HKEY_CURRENT_USER,

0,
KEY_READ | KEY_QUERY_VALUE,
key);

if( key = 0 )
{
directory = "";
return;
}

if( RegQueryValueEx(key, "BIN", NULL, type, value, size) <> ERROR_SUCCESS )
{
directory = "";
RegCloseKey(key);
return;
}

RegCloseKey(key);
return;

RegCloseKey(key);

Coming soon: An easy compiler for Aurora, a command line utility that allows you to compile your source files with one simple command and handles piping the output to the STDOUT, perfect for 3rd part IDEs

Also a note for Paul: The GetAuroraDir function only works when I add the return statement. I don't think the default return behaivor has been implemented yet for a "global sub" declaration.

Actually it is because you have more than one return statement.  Since the compiler can't know if your code is correct it assumes you know what your doing

The only time it will add the return statement is if one wasn't seen and it reached the end of the subroutine.

Thanks, I get it now. The return is no problem, I just didn't understand the behaivor.

Anyways, the function now subtracts the 'bin' part for you.
