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/core_keymap.h | 68 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 68 insertions(+) create mode 100644 apps/core_keymap.h (limited to 'apps/core_keymap.h') diff --git a/apps/core_keymap.h b/apps/core_keymap.h new file mode 100644 index 0000000000..39d35e9cd9 --- /dev/null +++ b/apps/core_keymap.h @@ -0,0 +1,68 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Copyright (C) 2020 by William Wilgus + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * + * This software is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY + * KIND, either express or implied. + * + ****************************************************************************/ +#ifndef CORE_KEYMAP_H +#define CORE_KEYMAP_H + +#include +#include +#include "config.h" +#define KEYREMAP_VERSION 1 +#define KEYREMAP_HEADERID (LAST_ACTION_PLACEHOLDER | (TARGET_ID << 8)) + +/* If exists remap file will be loaded at startup */ +#define CORE_KEYREMAP_FILE ROCKBOX_DIR "/keyremap.kmf" + +/* open_key_remap(filename , *fd (you must close file_descriptor), *fsize) + * checks/strips header and returns remaining count + * fd is opened and set to first record + * filesize contains the size of the remaining records +*/ +int open_key_remap(const char *filename, int *fd, size_t *filesize); + +/* load a remap file to allow buttons for actions to be remapped */ +int core_load_key_remap(const char *filename); + +/* + * entries consist of 3 int [action, button, prebtn] + * the header (VERSION, LAST_DEFINED_ACTION, count) is stripped by open_key_remap + * + * context look up table is at the beginning + * action_code contains (context | CONTEXT_REMAPPED) + * button_code contains index of first remapped action for the matched context + * prebtn_code contains count of actions in this remapped context + * [-1] REMAP_VERSION, REMAP_HEADERID, entry count(9) / DISCARDED AFTER LOAD + * [0] CORE_CONTEXT_REMAP(ctx1), offset1=(3), count=(1) + * [1] CORE_CONTEXT_REMAP(ctx2, offset2=(5), count=(2) + * [2] sentinel, 0, 0 + * [3] act0, btn, 0 + * [4] sentinel 0, 0 + * [5] act1, btn, 0 + * [6] act2, btn1 + * [7] 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. + */ + +#endif /* CORE_KEYMAP_H */ + -- cgit v1.2.3
