Two or more apps sharing same data directory?

in Programming Questions • 2 years ago

I want two separate apps (each will run on its own display) to share the same data directory, but can't make it work.

Tried making app2's data directory a symlink to app1's but that doesn't work.

Sym links of any kind were generally failing to work.

I also tried saving app2's PDE file to same directory as app1, but then you get "duplicate methods" errors.

I realize processing must not be designed to allow two apps to share a data directory, but does anyone know if it can be done?

The general goal is that app1 creates files that app2 needs to read. Simple but not easy to accomplish.

Any ideas are appreciated.

UPDATE: I discovered dataPath() and sketchPath() and am having some success with relative paths.

Still interested in other techniques. Again the reason these are two apps is so each can run on its own monitor.

as you already found out, you can direcly link to any path on your computer. doesnt have to be in the sketch or data folder.

still dont understand what it hast to do with running on different monitor. there are probably better ways to do that.

Thanks for replying.

I want to have two monitors off of one computer. Each one needs to run in "full screen" mode (no windows, no menubar).

I can't think of any way to do that without it being two apps -- even then I'm not sure it will work, probably depends on the the graphics card driver settings and all that stuff. I don't have two monitors to test with.

I'd do it with a single Processing app, but can one app have two windows? One of the windows MUST be full screen, the other could have a window I suppose.

I don't know about your monitor configuration. I have two stacked vertically (laptop on bottom, hires monitor above).

size(640, 2000);

creates a window the spans both. It they had the same dimensions, which they don't, it should be possible to create single window spanning and filling both screens.
