2017-08-02tap-dance: key + layer helperGergely Nagy
This adds the `ACTION_TAP_DANCE_DUAL_ROLE` helper, which makes it easy to have keys that act as a key on the first tap, and as a layer toggle on the second. Fixes #1532, reported by @Ptomerty. Signed-off-by: Gergely Nagy <algernon@madhouse-project.org>

2017-01-29race condition between oneshot_mods and tap_danceSjB
since the keycode for a tap dance process gets process only after the TAPPING_TERM timeout, you really only have ONESHOT_TIMEOUT - TAPPING_TERM time to tap or double tap on the key. This fix save the oneshot_mods into the action.state structure and applies the mods with the keycode when it's registered. It also unregisters the mod when the the tap dance process gets reset.

2016-08-17tap-dance: Major rework, to make it more reliableGergely Nagy
This reworks how the tap-dance feature works: instead of one global state, we have a state for each tap-dance key, so we can cancel them when another tap-dance key is in flight. This fixes #527. Since we have a state for each key, we can avoid situation where a keyup would mess with our global state. This fixes #563. And while here, we also make sure to fire events only once, and this fixes #574. There is one breaking change, though: tap-dance debugging support was removed, because dumping the whole state would increase the firmware size too much. Any keymap that made use of this, will have to be updated (but there's no such keymap in the repo). Also, there's a nice trick used in this rework: we need to iterate through tap_dance_actions in a few places, to check for timeouts, and so on. For this, we'd need to know the size of the array. We can't discover that at compile-time, because tap-dance gets compiled separately. We'd like to avoid having to terminate the list with a sentinel value, because that would require updates to all keymaps that use the feature. So, we keep track of the highest tap-dance code seen so far, and iterate until that index. Signed-off-by: Gergely Nagy <algernon@madhouse-project.org>

2016-07-22tap-dance: Support user_data for the callbacksGergely Nagy
Refactored the code a little, so all callbacks now receive a `user_data` pointer, which can be anything. As an example, the key pairs from `ACTION_TAP_DANCE_DOUBLE` now use this, and custom, built-in functions. This makes it easier to extend the tap dance functionality, and also simplifies the code a little. Signed-off-by: Gergely Nagy <algernon@madhouse-project.org>
2016-07-22tap-dance: Support for holding keysGergely Nagy
With this change, tap dance will now store the pressed state of the tap-dance key, and allow one to make an action sooner, while the key is still held, and only unregister when the key is released. The registration must happen in the `on_dance_finished` callback, while unregistering goes to `on_reset`. The surrounding code makes sure not to call either multiple times.

2016-07-16add an `anyway` and a `reset` callbackPavlos Vinieratos
when using tap dance, we have the `regular` callback that is called on the last tap. this commit adds an `anyway` callback that is called on every tap, and a `reset` callback that is called on reset of the tap dance taps.

To make it clear how this is different from `ACTION_FUNCTION_TAP`, lets explore a certain setup! We want one key to send `Space` on single tap, but `Enter` on double-tap. With `ACTION_FUNCTION_TAP`, it is quite a rain-dance to set this up, and has the problem that when the sequence is interrupted, the interrupting key will be send first. Thus, `SPC a` will result in `a SPC` being sent, if they are typed within `TAPPING_TERM`. With the tap dance feature, that'll come out as `SPC a`, correctly. The implementation hooks into two parts of the system, to achieve this: into `process_record_quantum()`, and the matrix scan. We need the latter to be able to time out a tap sequence even when a key is not being pressed, so `SPC` alone will time out and register after `TAPPING_TERM` time. But lets start with how to use it, first! First, you will need `TAP_DANCE_ENABLE=yes` in your `Makefile`, because the feature is disabled by default. This adds a little less than 1k to the firmware size. Next, you will want to define some tap-dance keys, which is easiest to do with the `TD()` macro, that - similar to `F()`, takes a number, which will later be used as an index into the `tap_dance_actions` array. This array specifies what actions shall be taken when a tap-dance key is in action. Currently, there are two possible options: * `ACTION_TAP_DANCE_DOUBLE(kc1, kc2)`: Sends the `kc1` keycode when tapped once, `kc2` otherwise. * `ACTION_TAP_DANCE_FN(fn)`: Calls the specified function - defined in the user keymap - with the current state of the tap-dance action. The first option is enough for a lot of cases, that just want dual roles. For example, `ACTION_TAP_DANCE(KC_SPC, KC_ENT)` will result in `Space` being sent on single-tap, `Enter` otherwise. And that's the bulk of it! Do note, however, that this implementation does have some consequences: keys do not register until either they reach the tapping ceiling, or they time out. This means that if you hold the key, nothing happens, no repeat, no nothing. It is possible to detect held state, and register an action then too, but that's not implemented yet. Keys also unregister immediately after being registered, so you can't even hold the second tap. This is intentional, to be consistent. And now, on to the explanation of how it works! The main entry point is `process_tap_dance()`, called from `process_record_quantum()`, which is run for every keypress, and our handler gets to run early. This function checks whether the key pressed is a tap-dance key. If it is not, and a tap-dance was in action, we handle that first, and enqueue the newly pressed key. If it is a tap-dance key, then we check if it is the same as the already active one (if there's one active, that is). If it is not, we fire off the old one first, then register the new one. If it was the same, we increment the counter and the timer. This means that you have `TAPPING_TERM` time to tap the key again, you do not have to input all the taps within that timeframe. This allows for longer tap counts, with minimal impact on responsiveness. Our next stop is `matrix_scan_tap_dance()`. This handles the timeout of tap-dance keys. For the sake of flexibility, tap-dance actions can be either a pair of keycodes, or a user function. The latter allows one to handle higher tap counts, or do extra things, like blink the LEDs, fiddle with the backlighting, and so on. This is accomplished by using an union, and some clever macros. In the end, lets see a full example! ```c enum { CT_SE = 0, CT_CLN, CT_EGG }; /* Have the above three on the keymap, TD(CT_SE), etc... */ void dance_cln (qk_tap_dance_state_t *state) { if (state->count == 1) { register_code (KC_RSFT); register_code (KC_SCLN); unregister_code (KC_SCLN); unregister_code (KC_RSFT); } else { register_code (KC_SCLN); unregister_code (KC_SCLN); reset_tap_dance (state); } } void dance_egg (qk_tap_dance_state_t *state) { if (state->count >= 100) { SEND_STRING ("Safety dance!"); reset_tap_dance (state); } } const qk_tap_dance_action_t tap_dance_actions[] = { [CT_SE] = ACTION_TAP_DANCE_DOUBLE (KC_SPC, KC_ENT) ,[CT_CLN] = ACTION_TAP_DANCE_FN (dance_cln) ,[CT_EGG] = ACTION_TAP_DANCE_FN (dance_egg) }; ``` This addresses #426.
