From f7bb9e21672566308ab837c370f27c10c154e6fc Mon Sep 17 00:00:00 2001 From: William Wilgus Date: Fri, 2 Apr 2021 21:34:29 -0400 Subject: Add custom action mapping to core results of an idea I discussed in IRC changed the way the lookup in the remap file works.. entries consist of 3 int [action, button, prebtn] context look up table is at the beginning action_code contains the (context | CONTEXT_REMAPPED) button_code contains the index of the first remapped action for the matched context [0] CORE_CONTEXT_REMAP(ctx1) offset1=(3), count=(1) [1] CORE_CONTEXT_REMAP(ctx2, offset2=(5), count=(1) [2] sentinel, 0, 0 [3] act0, btn, 0 [4] sentinel 0, 0 [5] act1, btn, 0 [6] sentinel, 0, 0 Note: last entry of each group is always the sentinel [CONTEXT_STOPSEARCHING, BUTTON_NONE, BUTTON_NONE] contexts must match exactly -- re-mapped contexts run before the built in w/ fall through contexts ie. you can't remap std_context and expect it to match std_context actions from the WPS context. -- Done -- Code for reading core remap entries -- Done -- import of core remap entires from disk -- Done -- plugin to set new key mapping (the hard part) The plugin is started and FULLY functional you can add actions and contexts you can change context, action, button, prebtn delete keymap files load keymapfiles save user keymaps test keymaps before applying them loading keymaps to core still requires restart ----------------------------------------------------------------------------------------------- Change-Id: Ib8b88c5ae91af4d540e1829de5db32669cd68203 --- apps/SOURCES | 1 + apps/action.c | 104 ++- apps/action.h | 11 + apps/core_keymap.c | 106 +++ apps/core_keymap.h | 68 ++ apps/main.c | 10 + apps/plugins/CATEGORIES | 1 + apps/plugins/SOURCES | 1 + apps/plugins/keyremap.c | 1616 ++++++++++++++++++++++++++++++++++ apps/plugins/lib/action_helper.h | 2 +- apps/plugins/lib/action_helper.pl | 2 + apps/plugins/lib/button_helper.h | 2 + apps/plugins/lib/button_helper.pl | 5 + apps/plugins/lua/rbdefines_helper.pl | 2 + 14 files changed, 1928 insertions(+), 3 deletions(-) create mode 100644 apps/core_keymap.c create mode 100644 apps/core_keymap.h create mode 100644 apps/plugins/keyremap.c diff --git a/apps/SOURCES b/apps/SOURCES index 1628524805..f440104a19 100644 --- a/apps/SOURCES +++ b/apps/SOURCES @@ -7,6 +7,7 @@ alarm_menu.c #endif abrepeat.c bookmark.c +core_keymap.c debug_menu.c filetypes.c language.c diff --git a/apps/action.c b/apps/action.c index b31c4fa927..3a4cc2ff64 100644 --- a/apps/action.c +++ b/apps/action.c @@ -69,6 +69,11 @@ static action_last_t action_last = .tick = 0, .wait_for_release = false, +#ifndef DISABLE_ACTION_REMAP + .check_remap = false, + .core_keymap = NULL, +#endif + #ifdef HAVE_TOUCHSCREEN .ts_data = 0, .ts_short_press = false, @@ -499,7 +504,7 @@ static inline int action_code_worker(action_last_t *last, int *end ) { int ret = ACTION_UNKNOWN;
