Overview
|
|
========
|
|
|
|
This is my personal userspace file. Most of my code exists here, as it's heavily shared.
|
|
|
|
|
|
Custom userspace handlers
|
|
-------------------------
|
|
|
|
Specifically QMK works by using customized handlers for everything. This allows for multiple levels of customization.
|
|
|
|
`matrix_scan` calls `matrix_scan_quantum`, which alls `matrix_scan_kb`, which calls `matrix_scan_user`.
|
|
`process_record` calls a bunch of stuff, but eventually calls `process_record_kb` which calls `process_record_user`
|
|
The same goes for `matrix_init`, `layer_state_set`, `led_set`, and a few other functions.
|
|
|
|
All (most) `_user` functions are handled here instead. To allow keyboard specific configuration, I've created `_keymap` functions that can be called by the keymap.c files instead.
|
|
|
|
This allows for keyboard specific configuration while maintaining the ability to customize the board.
|
|
|
|
My [Ergodox EZ Keymap](https://github.com/qmk/qmk_firmware/blob/master/keyboards/ergodox_ez/keymaps/drashna/keymap.c#L399) is a good example of this, as it uses the LEDs as modifier indicators.
|
|
|
|
|
|
Custom Keycodes
|
|
---------------
|
|
|
|
Keycodes are defined in the drashna.h file and need to be included in the keymap.c files, so that they can be used there.
|
|
|
|
A bunch of macros are present and are only included on boards that are not the Ergodox EZ or Orthodox, as they are not needed for those boards.
|
|
|
|
Included is a custom macro for compiling my keyboards. This includes the bootloader target (`:teensy`, `:avrdude`, or `:dfu`), and keeps RGBLIGHT, AUDIO and/or FAUXCLICKY enabled, if it previously was (regardless of the rules file).
|
|
|
|
This also includes a modified RESET keycode as well, that sets the underglow to red.
|
|
|
|
Layer Indication
|
|
----------------
|
|
|
|
This uses the `layer_state_set_*` command to change the layer color, to indicate which layer it is on. This includes the default keymap, as well.
|
|
|
|
Since this is done via userspace, it is the same between all systems.
|
|
|
|
Additionally, there is a custom keycode to toggle layer indication. And all RGB keycodes disable layer indication by default, as well. This way, I can leave special effects doing when I want.
|
|
|
|
Also. I use `rgblight_sethsv` since it works with animation modes (that support it).
|
|
|
|
|
|
Diablo Layer
|
|
------------
|
|
|
|
This layer has some special handling.
|
|
|
|
When Tap Dances are enabled, this layer has the ability to "spam" keypresses.
|
|
|
|
For instance, tapping the TD "1" twice causes the layer to hit "1" ever 1 second (appoximately). This is useful for auto-hotkeying skills (such as bone armor or devour).
|
|
|
|
Tappind once disables this, and switching layers temporarily disables this, until you switch back to the layer.
|
|
|
|
For critics that think this is cheating, search "diablo 3 num lock auto cast". This is just a simpler method, since I no longer own a normal (non QMK) numpad.
|
|
|
|
Secret Macros
|
|
-------------
|
|
|
|
With help from gitter and Colinta, this adds the ability to add hidden strings to be used for macros.
|
|
|
|
I have a number of long strings that I need to use that are semi-private. This uses the `__has_include` function to check for the file. If it exists, then it includes the custom text. Otherwise, it uses some default values.
|
|
|
|
If you would *also* like to take advantage of this feature, you'll first want to make sure your "secrets" file isn't included in the repo. Open `.git/info/exclude` and add `secrets.h` to that file, below the comments.
|
|
|
|
###### .git/info/exclude
|
|
```
|
|
# git ls-files --others --exclude-from=.git/info/exclude
|
|
# Lines that start with '#' are comments.
|
|
# For a project mostly in C, the following would be a good set of
|
|
# exclude patterns (uncomment them if you want to use them):
|
|
# *.[oa]
|
|
# *~
|
|
/users/drashna/secrets.h
|
|
```
|
|
|
|
Then you can create this file and add your macro strings to it:
|
|
|
|
###### secrets.h
|
|
```
|
|
PROGMEM const char secret[][64] = {
|
|
"secret1",
|
|
"secret2",
|
|
"secret3",
|
|
"secret4",
|
|
"secret5"
|
|
};
|
|
```
|
|
|
|
Replacing the strings with the codes that you need.
|
|
|
|
|
|
These are called in the `process_record_user` function, using this block:
|
|
```
|
|
case KC_SECRET_1 ... KC_SECRET_5:
|
|
if (!record->event.pressed) {
|
|
send_string_P(secret[keycode - KC_SECRET_1]);
|
|
}
|
|
return false;
|
|
break;
|
|
```
|
|
|
|
And this requires `KC_SECRET_1` through `KC_SECRET_5` to be defined, as well.
