qmk userspace for kuchosauronad0

Thanks to drashna and everyone else in the qmk_firmware/users/ directory :)

Overview

Keyboard Layout Templates

This borrows from @jola5's "Not quite neo" code. This allows me to maintain blocks of keymaps in the userspace, so that I can modify the userspace, and this is reflected in all of the keyboards that use it, at once.

This makes adding tap/hold mods, or other special keycodes or functions to all keyboards super easy, as it's done to all of them at once.

The caveat here is that the keymap needs a processor/wrapper, as it doesn't like the substitutions. However, this is as simple as just pushing it through a define. For instance:

#define LAYOUT_ergodox_wrapper(...) LAYOUT_ergodox(__VA_ARGS__)

Once that's been done and you've switched the keymaps to use the "wrapper", it will read the substitution blocks just fine.

Credit goes to @jola5 for first implementing this awesome idea.

Custom Keycodes

Declared in process_records.h and template.h and defined in process_record_user in template.c

Tap Dances

Set TAP_DANCE_ENABLE = yes in rules.mk. See file tap_dances.{c,h}

Leader Key

Set LEADER_ENABLE = yes in rules.mk. TODO: document tmux / vim / os

Unicode

TODO: Set idk in idc

Diablo Layer

Currently not in use.

Secret Macros

Set NO_SECRETS = yes in rules.mk.

With help from gitter and Colinta, this adds the ability to add hidden macros from other users.

First, I have several files that are hidden/excluded from Git/GitHub. These contain everything needed for the macros. To hide these files, open .git/info/exclude and add secrets.c and secrets.h to that file, below the comments.

And this requires KC_SECRET_1 through KC_SECRET_5 to be defined in your <name>.h file to define the keycodes for the new macros.

.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/kuchosauronad0/secrets.c
/users/kuchosauronad0/secrets.h

Then you can create these files:

secrets.c

#include "kuchosauronad0.h"  // replace with your keymap's "h" file, or whatever file stores the keycodes

#if (__has_include("secrets.h") && !defined(NO_SECRETS))
#include "secrets.h"
#else
// `PROGMEM const char secret[][x]` may work better, but it takes up more space in the firmware
// And I'm not familiar enough to know which is better or why...
static const char * const secret[] = {
  "test1",
  "test2",
  "test3",
  "test4",
  "test5"
};
#endif

bool process_record_secrets(uint16_t keycode, keyrecord_t *record) {
  switch (keycode) {
    case KC_SECRET_1 ... KC_SECRET_5: // Secrets!  Externally defined strings, not stored in repo
      if (!record->event.pressed) {
        clear_oneshot_layer_state(ONESHOT_OTHER_KEY_PRESSED);
        send_string_with_delay(secret[keycode - KC_SECRET_1], MACRO_TIMER);
      }
      return false;
      break;
  }
  return true;
}

secrets.h

static const char * const secrets[] = {
  "secret1",
  "secret2",
  "secret3",
  "secret4",
  "secret5"
};

Replacing the strings with the codes that you need.

name.c

In the <name>.c file, you will want to add this to the top:

__attribute__ ((weak))
bool process_record_secrets(uint16_t keycode, keyrecord_t *record) {
  return true;
}

This is so that the function can be called here, and replaced in the secrets.c file, and so it won't error out if it doesn't exist.

And then, in the process_record_user function, assuming you have return process_record_keymap(keycode, record) here, you'll want to replace the "final" return with the following. Otherwise, you want to replace the return true; with return process_record_secrets(keycode, record);

  return process_record_keymap(keycode, record) && process_record_secrets(keycode, record);
}

rules.mk

Here, you want your /users/<name>/rules.mk file to "detect" the existence of the secrets.c file, and only add it if the file exists. To do so, add this block:

ifneq ("$(wildcard $(USER_PATH)/secrets.c)","")
  SRC += secrets.c
endif

Additionally, if you want to make sure that you can disable the function without messing with the file, you need to add this to your /users/<name>/rules.mk, so that it catches the flag:

ifeq ($(strip $(NO_SECRETS)), yes)
    OPT_DEFS += -DNO_SECRETS
endif

Then, if you run make keyboard:name NO_SECRETS=yes, it will default to the test strings in your <name>.c file, rather than reading from your file.
