- Miryoku QMK
Miryoku QMK
Miryoku is an ergonomic, minimal, orthogonal, and universal keyboard layout. Miryoku QMK is the Miryoku implementation for QMK.
Branches
QMK master
Miryoku QMK is periodically merged upstream into QMK master and it is generally recommended to build directly from QMK master.
QMK master is at https://github.com/qmk/qmk_firmware/tree/master, and the corresponding Miryoku QMK readme is at https://github.com/qmk/qmk_firmware/tree/master/users/manna-harbour_miryoku.
Miryoku QMK development branch
The Miryoku QMK development branch is miryoku
and may contain new commits not yet merged into QMK master.
miryoku
is at https://github.com/manna-harbour/miryoku_qmk/tree/miryoku, and the corresponding Miryoku QMK readme is at https://github.com/manna-harbour/miryoku_qmk/tree/miryoku/users/manna-harbour_miryoku.
New commits can be seen at the top of the history with commit messages beginning [miryoku]
. After the new commits are squashed and merged upstream into QMK master by pull request the miryoku
branch is renamed and a new miryoku
branch is created from QMK master.
To checkout the miryoku
branch in your existing QMK build environment:
git remote add miryoku_qmk git@github.com:manna-harbour/miryoku_qmk.git # if using SSH
git remote add miryoku_qmk https://github.com/manna-harbour/miryoku_qmk.git # if using HTTPS
git fetch miryoku_qmk
git checkout --track miryoku_qmk/miryoku
Building
Local Builds
First set up the QMK build environment and build the default keymap for your keyboard.
Build with manna-harbour_miryoku
as the keymap name. Customised defaults for alternative layout options can be set in custom_rules.mk. Options can also be set or overridden at build time.
qmk
Build with the qmk
command. E.g.
qmk compile -c -kb crkbd -km manna-harbour_miryoku # build for crkbd
qmk flash -c -kb crkbd -km manna-harbour_miryoku # build for crkbd and flash
qmk compile -c -kb crkbd -km manna-harbour_miryoku -e MIRYOKU_ALPHAS=QWERTY -e MIRYOKU_NAV=INVERTEDT -e MIRYOKU_CLIPBOARD=WIN -e MIRYOKU_LAYERS=FLIP # build for crkbd with alternative layouts
make
First cd
to the repository root. Then build with make
. E.g.
make clean crkbd:manna-harbour_miryoku # build for crkbd
make clean crkbd:manna-harbour_miryoku:flash # build for crkbd and flash
make clean crkbd:manna-harbour_miryoku MIRYOKU_ALPHAS=QWERTY MIRYOKU_NAV=INVERTEDT MIRYOKU_CLIPBOARD=WIN MIRYOKU_LAYERS=FLIP # build for crkbd with alternative layouts
Workflow Builds
Firmware can be built via GitHub Actions workflows without use of a local build environment. Local tools are still required for flashing.
First log in to GitHub, fork the Miryoku QMK development branch repository, and enable workflows.
To access a workflow, visit the Actions tab and select the workflow. To download the firmware from a workflow run, select the workflow, select the workflow run, select the desired Artifacts, and unzip the downloaded zip file.
Workflow files are in /tudattr/qmk_firmware/src/commit/78c4907f34cc7936299ae5cc78460cb45f286e56/.github/workflows.
Build Examples
Copy one of the included Build Example workflow files, edit the name
value, and edit and add options and values as desired. Select Run workflow, select the Branch if desired, and activate Run workflow.
Options are specified in the with
section and are of the following form.
option: '["value"]'
For multiple values per option use the following form, and a matrix build will be performed for each combination of values across all options.
option: '["value1","value2"]'
The keyboard
option specifies the keyboard and is required. All other options are optional.
The alphas
, nav
, clipboard
, and layers
options correspond to the alternative layout options. The mapping
option corresponds to the alternative mapping options. Alternative layout and mapping options are given in the documentation in the form MIRYOKU_OPTION=VALUE
. To use here, convert to the form specified above. Use default
to represent the default value. Values for these five options are case-insensitive. See the Test All Configs workflow file for all supported values.
The rules
and config
options can be used to specify values to be appended to custom_rules.mk
and custom_config.h
, respectively. Separate multiple lines with \n
.
Build Inputs
The Build Inputs workflow can be used without editing workflow files. Select Run workflow, select the Branch and fill out the form as desired, and activate Run workflow.
Options are specified by entering values directly in the corresponding field. Multiple comma separated values can be entered per option and a matrix build will be performed for each combination of values across all options.
The Keyboard
option specifies the keyboard and is required. All other options are optional.
The Miryoku Alphas
, Miryoku Nav
, Miryoku Clipboard
, and Miryoku Layers
options correspond to the alternative layout options. The Miryoku Mapping
option corresponds to the alternative mapping options. Alternative layout and mapping options are given in the documentation in the form MIRYOKU_OPTION=VALUE
. To use here, enter the value
in the corresponding Miryoku Option
field. Use default
to represent the default value. Values for these five options are case-insensitive.
The custom_rules.mk
and custom_config.h
options can be used to specify values to be appended to the corresponding files. Join multiple lines with \n
.
Subset Mapping
The keymap, build options, and configuration are shared between keyboards. The layout is mapped onto keyboards with different physical layouts as a subset without code duplication using the QMK userspace feature and C macros.
Userspace
The keymap is defined for LAYOUT_miryoku
which is 10x4, with the outer 2
positions on the bottom row unused and the rest of the bottom row being the
thumb keys.

Community Layouts
To use the keymap on a keyboard supporting the community layouts feature,
LAYOUT_miryoku
is defined as a macro mapping onto the layout's own LAYOUT
macro, leaving the unused keys as KC_NO
.
For keyboards supporting multiple layouts for which subset mappings are
available, select the layout with FORCE_LAYOUT
in the make
command line when
building. E.g.:
make planck/rev6:manna-harbour_miryoku:flash FORCE_LAYOUT=planck_mit # planck_mit
make planck/rev6:manna-harbour_miryoku:flash FORCE_LAYOUT=ortho_4x12 # ortho_4x12
60_ansi
An angled ortho split layout is mapped onto the row-staggered keyboard. The rows are moved up to better position the thumb keys, the hands are separated as much as possible, and the left hand column angle is reversed to reduce ulnar deviation of the wrists.
An alternative subset mapping is also provided without reverse column angle. To
select this mapping, append MIRYOKU_MAPPING=NOREVERSEANGLE
to the make
command line when building.
Another alternative subset mapping is provided mapping only the 3x10 alphas,
plus spacebar for space / Nav, with the remainder being the default 60_ansi
keymap with semicolon in place of quote. To select this mapping, append
MIRYOKU_MAPPING=LITE
to the make
command line when building.

make dz60:manna-harbour_miryoku:flash MIRYOKU_MAPPING=NOREVERSEANGLE # dz60, without reverse column angle
make dz60:manna-harbour_miryoku:flash MIRYOKU_MAPPING=LITE # dz60, with lite mapping
alice
This is a hybrid mapping. Only the 3x10 alphas plus spacebars as primary thumb keys are mapped. The remaining keys are the same as the default keymap but with semicolon in place of quote. The keys adjacent to the spacebars are also mapped as corresponding thumb keys but may not be usable as such.
Keyboards supporting this layout: cheshire/curiosity, handwired/owlet60, mechlovin/adelais, projectkb/alice, sck/osa, axolstudio/yeti, coarse/cordillera, edda, evyd13/wonderland, fallacy, kb_elmo/sesame, keebsforall/coarse60, ramonimbao/aelith, sneakbox/aliceclone, tkc/osav2, zoo/wampus.
alice_split_bs
This is a hybrid mapping. Only the 3x10 alphas plus spacebars as primary thumb keys are mapped. The remaining keys are the same as the default keymap but with semicolon in place of quote. The keys adjacent to the spacebars are also mapped as corresponding thumb keys but may not be usable as such.
Keyboards supporting this layout: cheshire/curiosity, ergosaurus, handwired/colorlice, handwired/owlet60, mechlovin/adelais, projectkb/alice, sck/osa, tgr/alice, xelus/valor/rev1, xelus/valor/rev2, axolstudio/yeti, coarse/cordillera, edda, evyd13/wonderland, fallacy, kb_elmo/sesame, keebsforall/coarse60, nightly_boards/alter/rev1, ramonimbao/aelith, seigaiha, sneakbox/aliceclone, tkc/osav2, zoo/wampus.
ergodox
For the ergodox layout, the main 5x3 alphas are used as usual. The primary and secondary thumb keys are the inner and outer 2u thumb keys and the tertiary thumb key is the innermost key of the partial bottom row. The remaining keys are unused.
An alternative subset mapping is provided with all keys shifted up one row creating thumb keys in the original alpha area. To select this mapping, append MIRYOKU_MAPPING=SHIFTED_ROWS
to the make
command line when building.
Another alternative subset mapping is provided as for MIRYOKU_MAPPING=SHIFTED_ROWS
but with the thumb keys shifted one position in the direction of thumb extension. To select this mapping, append MIRYOKU_MAPPING=SHIFTED_ROWS_EXTENDED_THUMBS
to the make
command line when building.
Another alternative subset mapping is provided as for MIRYOKU_MAPPING=SHIFTED_ROWS_EXTENDED_THUMBS
but with the pinkie column moved down one row. To select this mapping, append MIRYOKU_MAPPING=SHIFTED_ROWS_EXTENDED_THUMBS_PINKIE_STAGGER
to the make
command line when building.
Keyboards supporting this layout: ergodone, ergodox_ez, ergodox_infinity, hotdox.
Example build command lines:
make ergodox_infinity:manna-harbour_miryoku:flash # ergodox_infinity
make ergodox_ez:manna-harbour_miryoku:flash # ergodox_ez
make ergodox_ez:manna-harbour_miryoku:flash MIRYOKU_MAPPING=SHIFTED_ROWS # ergodox_ez, shifted rows

An alternative with 180 degree rotation is also provided to enable the USB cable to be relocated for use with laptops. To select this mapping, append MIRYOKU_MAPPING=ROTATE
to the make
command line when building.
Keyboards supporting this layout: newgame40, nimrod, marksard/rhymestone, pabile/p40.
Example build command lines:
make marksard/rhymestone:manna-harbour_miryoku:flash # marksard/rhymestone
make pabile/p40:manna-harbour_miryoku:flash MIRYOKU_MAPPING=ROTATE # pabile/p40, rotate
ortho_4x12
For the ortho_4x12 layout, the middle two columns, and the 2 keys on each end of the bottom row are unused. This allows the hands to be positioned without ulnar deviation of the wrists.
For split keyboards using this layout the halves can be positioned and rotated
for each hand and so an alternative mapping is provided. The right half is as
follows: The rightmost column bottom 3 keys is the pinkie column. The middle 4
columns top 3 rows are for the remaining fingers. The pinkie column is one row
lower than the other columns to provide some column stagger. The bottom row
left 3 keys are the thumb keys. The remaining keys are unused. To select this
mapping, append MIRYOKU_MAPPING=SPLIT
to the make
command line when
building.
An alternative with extended thumb position but without pinkie column stagger is
also provided. To select this mapping, append MIRYOKU_MAPPING=EXTENDED_THUMBS
to the make
command line when building.
