zmk-javelin-steno

ZMK module that integrates the Javelin steno engine for on-board stenography on ZMK keyboards.

Status

Dropped — my hardware (nice_nano_v2, 1MB flash) can't fit any dictionary. Build passes on boards with sufficient flash but has not been hardware tested. Contributions welcome.

Flash Requirements

Total flash usage (firmware + engine + dict) on a corne split (central half):

Dictionary Total flash
Plover + Lapwing 3.78 MB
Plover only 2.53 MB
Lapwing only 2.08 MB
No dict (engine only) 534 KB

Setup

Add to your west.yml:

manifest:
  remotes:
    - name: afiqzudinhadi
      url-base: https://github.com/afiqzudinhadi
    - name: jthlim
      url-base: https://github.com/jthlim
  projects:
    - name: zmk-javelin-steno
      remote: afiqzudinhadi
      revision: main
    - name: javelin-steno
      remote: jthlim
      revision: main
      path: zmk-javelin-steno/javelin

Add to your .conf:

CONFIG_ZMK_JAVELIN_STENO=y
CONFIG_ZMK_JAVELIN_STENO_DICT_PLOVER=y
CONFIG_ZMK_JAVELIN_STENO_DICT_LAPWING=y
CONFIG_CPLUSPLUS=y
CONFIG_LIB_CPLUSPLUS=y
CONFIG_HEAP_MEM_POOL_SIZE=32768

Set CONFIG_ZMK_JAVELIN_STENO_DICT_PLOVER and CONFIG_ZMK_JAVELIN_STENO_DICT_LAPWING to choose which dictionaries to include. Both can be enabled simultaneously.

Add to your .keymap (see steno_keys.h for all available key bindings):

#include <dt-bindings/zmk/javelin_steno.h>
#include <behaviors/javelin_steno.dtsi>

steno_layer {
    bindings = <
        &javsteno STENO_S1  &javsteno STENO_TL  &javsteno STENO_PL ...
    >;
};
