Using environment variable in data-path

beginners
#1

I’m compiling an app for OSX and Windows. On OSX it is easy to move the ‘data’ folder from OF into the actual app itself using the following commands:
ofEnableDataPath();
ofSetDataPathRoot();

However, on Windows I would need to have the ‘data’ folder in the user’s AppData folder location. Typically the %APPDATA% is used in e.g. installers, but it doesn’t seem that OF is recognizing the environment variable in the strings. Is there a way to point the data-path-root to the appdata folder by using the environment variable?

No UI, no crash, no activity with app on Windows 10

not super familiar with window env variables but could you use something like this to read the environment variable?

I ended up using the getenv() command. Another tricky thing is that Windows uses backslashes in the locations, which you cannot add intro the string… so I need to add another char and replace it with the hexcode for backslash :confused: but it works

#ifdef TARGET_WIN32
string newRoot = ofToString( getenv(“PUBLIC”)) + ofToString("=Documents=Sxratch");
ofStringReplace(newRoot, “=”, “\x5C”); // need to put in the backslash
ofEnableDataPath();
ofSetDataPathRoot(newRoot);
#endif
