Load mapping definitions automatically (in Max)

Load mapping definitions automatically (in Max)

I'm at a stage in my work where I'm very satisfied with my current mappings.  Do I need to use Webmapper to load mapping connections?

I'm looking through the mapper .maxhelp files, searching for any examples of how to instantiate mapping connections within a Max patch. In the past, we've been able to format messages to, say, [mapper] to create the actual mapping connections. Ideally, this bit of programming should read the .JSON file, which is generated by the GUI.

Is this still possible?

By the way, I've also noticed that one can use @definition with [mapper]. Very nice !!  It would be interesting if [mapper] could contain a similar argument for the actual mapping connections.

[mapper @alias foo @definition sample_device_definition.json @connection mapping_connections.json]

However, timing issues would need to be worked out, correct? The devices need to be identified on the network, before [mapper] reads mapping connections.



Thank you

Or, some cmd line I can use to load the .JSON mapping connections file?

Hi Andrew,

The mappersession python module (which works as the backend for webmapper) can be used in this way, e.g.

python3 -m mappersession --load mymapping.json

You can also use it to save or unload mapping files. There are flags you can pass to determine whether mappersession should try to load maps flexibly or using exact device/signal name matching, whether to wait for the devices to show up, whether to keep waiting and keep recreating the maps if the devices appear again, etc.

You can even load multiple files at the same time, and if you pass the flag -—interactive mappersession will also declare its own libmapper signals for controlling loading/unloading of the maps.

Controlling things from within Max still requires seeing messages (e.g. /map, /unmap) to the libmapper admin bus using the [oscmulticast] object. There is not currently a [mpr.graph] object for Max but we have considered creating one.

Cheers,

Joe

Thanks

`/map and /unmap`...of course I remember that now.  I probably have a Max subpatch already built for this.  If I remember well, I simply need to make sure the actual syntax of what follows `/map` is still the same as when I used it, last time.  I know the syntax (e.g., @argument names get changed, some times)

I really like the `mappersession` option, though; however, was not able to get it to work.  Here's a print-out of what I did (below).  I'm sure this is just an issue with my lack of knowledge of implementation.  So, as always, if `mappersession` has been formally documented somewhere, please let me know. Thanks a bunch.
