pattrstorage autorestore and standalones

Hi,

Here is a solution for doing this that I have used. It uses a bit of javascript to work out the absolute path to the /contents/support folder (if running as a standlaone), then explicitly reads/writes the named json file there.

As noted in another thread on this topic, this only works if the pattrstorage object has no reference to the json file when app is built (i.e. do not 'read' the json file before building) My patch only automatically reads when the javascript detects that the patch is running in Max Runtime (i.e. as a standalone) to avoid creating this reference.

(Trying to write to a json file which is 'included' in the application currently doesn't seem to work, throwing a '-1 write error' in the Max window)

The max patch will require changing a few messages to match your application name in the 'writeSettings' patcher

The javascript (save as getPathToPattrstorageDefaults.js)

// Platform independent initialisation of default file path (for pattrstorage)
// Differentiates between runtime (i.e. standalone) or full Max environment
// Will Crossland

outlets = 2;
setoutletassist(0, "Bang (if standalone)")
setoutletassist(1, "filepath");

function bang()
{
if (0 == max.isruntime) {
outlet (1, jsarguments[2]);
return;
}

if (max.os == "windows") {
outlet (1, max.apppath + "/support/" + jsarguments[2]);
}

if (max.os == "macintosh") {
outlet (1, max.apppath + "/" + jsarguments[1] + ".app/Contents/support/" + jsarguments[2]);
}
outlet(0, "bang");
}
