When I do sudo keyd with the following settings, I get ERROR: max layers (32) exceeded.

Can we Increase max layers?

nsbgn commented 1 year ago

Age-old question: what's your use case? ;)

tkna91 commented 1 year ago

I have been doing the following, but have reached our limits.

Calling another layer from a layer
Create a layer of layer + modifier key (like [layer1+shift])

Of course, I could organize and make less important layers unused, etc., but I thought it would be nice to have more upper limits.

tkna91 commented 1 year ago

If it is not a problem by design, I would suggest eliminating the upper limit and using the amount of memory as the upper limit. The flexibility of keyd's key remapping is the highest I have seen so far, and I think one of the charms of keyd is that it is structured in such a way that it is possible to increase the number of layers exponentially.

If eliminating the upper limit would cause design problems, I would be happy to see it increased.

rvaiya commented 1 year ago

Everything in keyd is statically allocated for reasons of efficiency (and portability). The limits set are intended to accommodate most real world use cases. If users find themselves bumping up against them, then they either need to modify their config (common), or the limits need to be re-evaluated. I am not opposed to increasing the layer limit, but I would need to see a compelling use case first.

Can you post your config?

tkna91 commented 1 year ago

My setup was too confusing to show to anyone but myself, so I reorganized it a bit and reduced the number of layers. However, I am almost at the upper limit.

rvaiya commented 1 year ago

@tkna91 That is indeed a lot of layers :P. But by my count, you still have another 11 to play with in your largest example. Have you run up against this limit in practice?

tkna91 commented 1 year ago

Yes, before I organized my settings, I was commenting out or deleting things that were used infrequently and making do.

tkna91 commented 4 months ago

In the music production software called REAPER, you can assign 128 values * 16 channels = 2048 operations per MIDI controller to any action (like a command) using the Control Change protocol of MIDI. https://anotherproducer.com/online-tools-for-musicians/midi-cc-list/

I would like to control this with the keyboard using keyd layers and the following commands, etc., but unfortunately the maximum number of layers is currently not enough.

sendmidi dev "Midi Through Port-0" ch 16 cc 127 0

Is it possible to increase the maximum number of layers used, for example, with something like the global option below?

[global]
max_layers = 128

I may have asked this question sometime ago? Sorry if fixed values are required by design.

By rewriting the symbolic link to /etc/keyd/common, I was able to set up a pseudo-setup of what I wanted to do! Glad I did. @rvaiya Thanks to the command() you created, I was able to make it happen. Isn't this a pretty good idea?
