Samuel's Literate QMK Config

This is my qmk firmware for my keyboard. I grew tired of organizing the keycode array in plain text so I made it a literate .org file. I've never done this before, so bear with me.

Keymap

- - - - - - - - - - - -
- - - - - - - - - - - -
- - - - - - - - - - - -
- - - - - - - - - - - -

This is my "pretty" org mode organized table for my main dvorak layer. If you don't use org mode, it won't be that exiting, but if you enjoy working in org mode, you can edit this table directly, and this file is tangled to the actual keymap. No more organizing spaces or converting to and from comments.

T_LRSE QUOT COMM DOT P Y F G C R L T_RRSE
T_LSFT A O E U I D H T N S T_RSFT
T_LCTL SCLN Q J K X B M W V Z T_RCTL
T_LGUI T_LALT UP DOWN BSPC TAB ENT SPC LEFT RIGHT T_RALT T_RGUI

I tried to keep my layout bare bones, just what would be available on a normal keyboard, minus some keys I never used. The bottom left copies a normal keyboards symbols from shifted numbers, and the rest is placed where convenient, with some considerations for one handed use, hence the shortcuts in the top left.

EZUNDO EZCOPY EZCUT EZPSTE INS EQL 7 8 9 F11
ESC CAPS PGUP PGDN F4 ASTR 4 5 6 0
EXLM AT HASH DLR PERC CIRC 1 2 3 F12
EZUP EZDOWN AMPR PIPE EZLEFT EZRGHT

But wait, we are missing several important keys!? yes, well, the modifier keys all do other keys when tapped. More about that in the keymap section.

Keymap Conversion in Python

This python can convert that table into the array needed for the keymap file. It simply prepends every key with "KC_". I used to use a dictionary to convert some keys from the table into qmk keycodes, but the double convertion was unneccessary so I simply prepended all my macros with KC and moved all the implementation to the `process-user-input` function.

#+NAME:layer-to-array

results = "{"
row = 0
while row < len(keys):
  results += '{ '
  key = 0
  while key < len(keys[row]):
    keyName = str(keys[row][key])
    if keyName == '--':
      keyName = 'TRANSPARENT'
    results += 'KC_' + keyName
    if key != 11:
      results += ', '
    key+=1
  results += '}'
  if row != 3:
    results += ','
  results += '\n'
  row+=1
results += '},\n'
return results

keymap.c

Now that we have done all the hard work, lets layout our keymap file then define our macros.

Headers And Layer Declaration

#include QMK_KEYBOARD_H

extern keymap_config_t keymap_config;

static uint16_t tap_timers[10]  = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};

char last_mod = -1;

enum planck_layers {
  _DVORAK,
  _RISE
};

// where the 'T_' communicates how the key does something different when tapped.
enum planck_keycodes {
  DVORAK = SAFE_RANGE,
  KC_T_LALT,
  KC_T_RALT,
  KC_T_LGUI,
  KC_T_RGUI,
  KC_T_LCTL,
  KC_T_RCTL,
  KC_T_LSFT,
  KC_T_RSFT,
  KC_T_LRSE,
  KC_T_RRSE,

  KC_EZLEFT,
  KC_EZUP,
  KC_EZDOWN,
  KC_EZUNDO,
  KC_EZCOPY,

};

const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {

Import Key table

[_DVORAK] =
<<layer-to-array(home-layer)>>
[_RISE] =
<<layer-to-array(secondary-layer)>>

Process User Input

Tap Key Functionality

These methods define how I implemented the tap mechanic. Basically, I believe that pressing any other key should be grounds for the hold functionality to be assumed. My natuaral typing style experiences no delays from my method.

};

void mod_press(uint16_t hold_code, int id) {
    tap_timers[id] = timer_read();
    last_mod = id;
    register_code(hold_code);
}

void mod_lift(uint16_t tap_code, uint16_t hold_code, int id) {
    unregister_code(hold_code);
    if (last_mod == id && timer_elapsed(tap_timers[id]) < TAPPING_TERM) {
      tap_code16(tap_code);
      last_mod = -1;
    }
}

Set DVORAK layout

The function that filter's user inputs and applies macros, the begginning is pretty basic, setting our main layer and configuring our secondary layer.

bool process_record_user(uint16_t keycode, keyrecord_t *record) {
  switch (keycode) {
    case DVORAK:
      if (record->event.pressed) {
        set_single_persistent_default_layer(_DVORAK);
      }
      return false;
      break;

Alt and ()

Left and right alt are ( and ) when tapped. I put them on alt instead of a more conveniant key like control because parentheses do not need to be shift modified ever, unlike some other tap keys seen in the next sections.

case KC_T_LALT:
if (record->event.pressed) {
  mod_press(KC_LALT, 0);
 } else {
  mod_lift(S(KC_9), KC_LALT, 0);
 }
return false;
break;
case KC_T_RALT:
if (record->event.pressed) {
  mod_press(KC_RALT, 1);
 } else {
  mod_lift(S(KC_0), KC_RALT, 1);
 }
return false;
break;

Gui and `\

I place gui in the bottom corner because I believe it is the hardest key to reach, so gui seemed like a good fit for a dedicated key that I never want to have to spam. For tap keys, I used equally unused keys that are not apart of the number pad or shifted number keys.

case KC_T_LGUI:
if (record->event.pressed) {
  mod_press(KC_LGUI, 2);
 } else {
  mod_lift(KC_GRAVE, KC_LGUI, 2);
 }
return false;
break;
case KC_T_RGUI:
if (record->event.pressed) {
  mod_press(KC_RGUI, 3);
 } else {
  mod_lift(KC_BSLASH, KC_RGUI, 3);
 }
return false;
break;

Ctrl and []

Left and right control are [] respectively when they are tapped, making { and } also very convenient.

case KC_T_LCTL:
if (record->event.pressed) {
  mod_press(KC_LCTL, 4);
 } else {
  mod_lift(KC_LBRACKET, KC_LCTL, 4);
 }
return false;
break;
case KC_T_RCTL:
if (record->event.pressed) {
  mod_press(KC_RCTL, 5);
 } else {
  mod_lift(KC_RBRACKET, KC_RCTL, 5);
 }
return false;
break;

Shft and =-

I place shift on the home row, so having '-' right of my pinkie is standard, and it only felt natural to put its opposite, '=/+' on the other side. I put an extra one on the right side in the secondary layer for the num pad.

case KC_T_LSFT:
if (record->event.pressed) {
  mod_press(KC_LSFT, 6);
 } else {
  mod_lift(KC_EQUAL, KC_LSFT, 6);
 }
return false;
break;
case KC_T_RSFT:
if (record->event.pressed) {
  mod_press(KC_RSFT, 7);
 } else {
  mod_lift(KC_MINUS, KC_RSFT, 7);
 }
return false;
break;

Rise, DEL, and /

I use the top corners as rise because I decided that I do not like using layers with my thumbs. It feels uncomfortable to hold keys down with the side of my thumb, and backspace, tab, enter, and spacebar keep them satisfied. My pinky is for holding modifiers, so it makes sense to put the layer key with the other modifiers. Both my left and right layer keys activate the same layer which also makes sense to me. You wouldn't want left and right shift to do different things

I used to have escape in the top left, but I use delete a lot more, and putting escape under a layer has not been a problem at all. I put / in the top right corner again mimicing a standard dvorak keyboard.

case KC_T_LRSE:
if (record->event.pressed) {
  tap_timers[8] = timer_read();
  last_mod = 8;
  layer_on(_RISE);
 } else {
  layer_off(_RISE);
  if (last_mod == 8 && timer_elapsed(tap_timers[8]) < TAPPING_TERM) {
    tap_code16(KC_DELETE);
    last_mod = -1;
  }
 }
return false;
break;
case KC_T_RRSE:
if (record->event.pressed) {
  tap_timers[9] = timer_read();
  last_mod = 9;
  layer_on(_RISE);
 } else {
  layer_off(_RISE);
  if (last_mod == 9 && timer_elapsed(tap_timers[9]) < TAPPING_TERM) {
    tap_code16(KC_SLASH);
    last_mod = -1;
  }
 }
return false;
break;

EZ keys

I use ctrl+shift+arrows keys a lot, so when the layer key is pressed they became lazy versions of themselves with control and shift already pressed.

I also added undo, copy, paste, and cut to be easily available with only the left hand like on a qwerty or colemek keyboard.

case KC_EZRGHT:
if (record->event.pressed) {
  register_code(KC_LCTL);
  tap_code16(S(KC_RGHT));
  unregister_code(KC_LCTL);
  last_mod = -1;
 }
return false;
break;
case KC_EZLEFT:
if (record->event.pressed) {
  register_code(KC_LCTL);
  tap_code16(S(KC_LEFT));
  unregister_code(KC_LCTL);
  last_mod = -1;
 }
return false;
break;
case KC_EZDOWN:
if (record->event.pressed) {
  register_code(KC_LCTL);
  tap_code16(S(KC_DOWN));
  unregister_code(KC_LCTL);
  last_mod = -1;
 }
return false;
break;
case KC_EZUP:
if (record->event.pressed) {
  register_code(KC_LCTL);
  tap_code16(S(KC_UP));
  unregister_code(KC_LCTL);
  last_mod = -1;
 }
return false;
break;
case KC_EZUNDO:
if (record->event.pressed) {
  tap_code16(C(KC_Z));
  last_mod = -1;
}
return false;
break;
case KC_EZCOPY:
if (record->event.pressed) {
  tap_code16(C(KC_C));
  last_mod = -1;
}
return false;
break;
case KC_EZCUT:
if (record->event.pressed) {
  tap_code16(C(KC_X));
  last_mod = -1;
}
return false;
break;
case KC_EZPSTE:
if (record->event.pressed) {
  tap_code16(C(KC_P));
  last_mod = -1;
}
return false;
break;

Standard inputs interupt tap

Finally, if just a standard key is tapped, set the interupted flag.

  }
  last_mod = -1;
  return true;
}
