+# User Space Code for Paul Ewing
+
+This folder contains my user space code.
+
+## Key Repeater
+
+I've implemented a key repeater utility in [./key_repeater.h](./key_repeater.h)
+and [./key_repeater.c](./key_repeater.c) that is similar in concept to the
+"rapid fire" feature many game controllers come with. The intent behind this is
+that the user can hold down a key and while it is pressed, a keycode will be
+repeatedly sent. I have found this useful in certain games and during game
+development.
+
+The duration of the key press as well as the time between key presses is
+slightly randomized by design. This is to simulate more realistic human
+behavior. By setting the minimum and maximum duration fields to the same value
+in the configuration, this randomization can be disabled.
+
+**Note:** Please be aware that this might be against the terms of service in
+certain games so use your own discretion before using this feature.
+
+### How to Use
+
+Define the repeater and then configure and allocate it in your keymap's
+initialization process:
+
+```c
+static struct key_repeater_t* click_repeater = NULL;
+
+void keyboard_post_init_user(void) {
+ // Seed the random number generator which is used by the key repeater
+ srand(timer_read32());
+
+ // Configure and instantiate a key repeater for mouse button 1 "rapid fire"
+ struct key_repeater_config_t cfg = {
+ .key = KC_BTN1, // Press mouse button 1 (Left click)
+ .key_duration_min = 20, // Press key for 20 to 50 milliseconds
+ .key_duration_max = 50,
+ .wait_duration_min = 90, // Wait for 90 to 140 milliseconds before pressing again
+ .wait_duration_max = 140,
+ };
+
+ click_repeater = kr_new(&cfg);
+}
+```
+
+Make sure the key repeater is polled during matrix scanning:
+
+```c
+void matrix_scan_user(void) {
+ kr_poll(click_repeater);
+}
+```
+
+Define a custom keycode that will enable/disable the repeater:
+
+```c
+enum {
+ RP_BTN1 = SAFE_RANGE, // Click repeatedly while key is held
+};
+```
+
+Assign the keycode to a key in your `LAYOUT(...)` macro.
+
+Define the logic to enable/disable the repeater when the custom keycode is
+pressed or released:
+
+```c
+bool process_record_user(uint16_t keycode, keyrecord_t *record) {
+ switch (keycode) {
+ case RP_BTN1:
+ if (record->event.pressed) {
+ kr_enable(click_repeater);
+ } else {
+ kr_disable(click_repeater);
+ }
+ return false;
+ default:
+ return true;
+ }
+}
+```
+
