This is a generalization of the existing concept of tri-layer support
that's already well known. Essentially, a conditional-layer
configuration activates a particular layer (the then-layer) when one or
more other layers (the if-layers) are activated.
This is commonly used on ortho keyboards to activate a third "adjust"
layer while the primary two layers ("lower" and "raise") are active.
* Add optional `hold-trigger-key-positions` hold-tap configuration
* Leverage configuration for decision making around when to trigger
hold decision in hold-taps.
* Add docs for new configuration.
* Tests for the new config/decision logic.
Switched the GPIO matrix driver to debouncing using a simple integrator
algorithm. Whenever a key is pressed, we now scan at a rate controlled
by debounce-scan-period-ms (default 1 ms) until all keys are released,
then return to either waiting for an interrupt or polling more slowly.
The timers for key press and release can now be controlled separately,
so debounce-period is deprecated in favor of debounce-press-ms and
debounce-release-ms. Global Kconfig options
ZMK_KSCAN_DEBOUNCE_PRESS_MS and ZMK_KSCAN_DEBOUNCE_RELEASE_MS are also
added to make these easier to set.
Added documentation for debouncing options.
* Some runtimes (e.g. podman), require explicit registries in image URLs
or will prompt for the user to select one, which breaks things like
VSCode remote container rebuilds.
* Make the synthetic "base name" property double underscore prefixed,
since internal, and to avoid future conflicts w/ YAML format add'ns.
* Switch to PS hash dictionaries for our metadata collections for saner
data inspection/use.
* Use unified config template repo that uses an external
build matrix YAML file.
* Proper handling for onboard keyboards, including splits, and
supports for appending the right build matrix once selected.
Recent refactoring of the font handling seems to have broken the display
of the last symbol of the output status widget. From my analysis the
last symbol is truncated because the buffer simply is too small.
Increasing the buffer size to 9 fits all three possible symbols.
For example, Debian Bullseye (current stable) packages Node.js version
12, which is too old to build the docs successfully. At least version 14
is required, and version 16 is current. General advice seems to be to
install from the NodeSource repo instead of your distro's repo, so I
added a suggestion to the docs.
* Add ZMK_HID_CONSUMER_REPORT_USAGES choice to allow choosing
between full consumer usage range, with poor OS compat,
or basic consumer usage range, with broader compat.
