This commit improves the heuristic used in generate-keyboard-c for inferring key handedness from keyboard.json geometry data. Heuristic summary: 1. If the layout is symmetric (e.g. most split keyboards), guess the handedness based on the sign of (x - layout_x_midpoint). 2. Otherwise, if the layout has a key of >=6u width, it is probably the spacebar. Form a dividing line through the spacebar, nearly vertical but with a slight angle to follow typical row stagger. 3. Otherwise, assume handedness based on the widest horizontal separation. I have tested this strategy on a couple dozen keyboards and found it to work reliably. * Use Optional instead of `| None`. * Refactor to avoid lambdas. * Remove trailing comma in chordal_hold_layout. * Minor docs edits. * Revise to allow combining multiple same-hand mods. This commit revises Chordal Hold as described in discussion in https://github.com/qmk/qmk_firmware/pull/24560#discussion_r1894655238 1. In "RCTL_T(KC_A)↓, RSFT_T(KC_C)↓, RCTL_T(KC_A)↑" before the tapping term, RCTL_T(KC_A) is settled as tapped. 2. In "RCTL_T(KC_A)↓, RSFT_T(KC_C)↓, RSFT_T(KC_C)↑", both RCTL_T(KC_A) and RSFT_T(KC_C) are settled as tapped. 3. In "RCTL_T(KC_A)↓, RSFT_T(KC_C)↓, KC_U↓" (all keys on the same side), both RCTL_T(KC_A) and RSFT_T(KC_C) are settled as tapped. 4. In "RCTL_T(KC_A)↓, RSFT_T(KC_C)↓, LSFT_T(KC_T)↓", with the third key on the other side, we allow Permissive Hold or Hold On Other Keypress to decide how/when to settle the keys. 5. In "RCTL_T(KC_A)↓, RSFT_T(KC_C)↓" held until the tapping term, the keys are settled as held. 1–3 provide same-hand roll protection. 4–5 are for combining multiple same-hand modifiers. I've updated the unit tests and have been running it on my keyboard, for a few hours so far, and all seems good. I really like this scheme. It allows combining same-side mods, yet it also has roll protection on streaks. For me, this feels like Achordion, but clearly better streak handling and improved responsiveness. * Fix formatting. * Add a couple tests with LT keys. * Remove stale use of CHORDAL_HOLD_LAYOUT. * Fix misspelling lastest -> latest * Handling tweak for LTs and tests. * Fix formatting. * More tests with LT keys. * Fix formatting. |

THIS IS THE DEVELOP BRANCH
Warning- This is the develop branch of QMK Firmware. You may encounter broken code here. Please see Breaking Changes for more information.
Quantum Mechanical Keyboard Firmware
This is a keyboard firmware based on the tmk_keyboard firmware with some useful features for Atmel AVR and ARM controllers, and more specifically, the OLKB product line, the ErgoDox EZ keyboard, and the Clueboard product line.
Documentation
The docs are powered by VitePress. They are also viewable offline; see Previewing the Documentation for more details.
You can request changes by making a fork and opening a pull request.
Supported Keyboards
The project also includes community support for lots of other keyboards.
Maintainers
QMK is developed and maintained by Jack Humbert of OLKB with contributions from the community, and of course, Hasu. The OLKB product firmwares are maintained by Jack Humbert, the Ergodox EZ by ZSA Technology Labs, the Clueboard by Zach White, and the Atreus by Phil Hagelberg.
Official Website
qmk.fm is the official website of QMK, where you can find links to this page, the documentation, and the keyboards supported by QMK.
