To enable: create registry key under `HKEY_CURRENT_USER\Control Panel\Input Method\EnableHexNumpad` of type `REG_SZ` called `EnableHexNumpad`, set its value to 1, and reboot. This method is not recommended because of reliability and compatibility issue, use WinCompose method below instead. * UC_WINC: Windows Unicode input using WinCompose. Requires [WinCompose](https://github.com/samhocevar/wincompose). Works reliably under many (all?) variations of Windows. +To type multiple characters for things like (ノಠ痊ಠ)ノ彡┻━┻, you can use `send_unicode_hex_string()` much like `SEND_STRING()` except you would use hex values seperated by spaces. +For example, the table flip seen above would be `send_unicode_hex_string("0028 30CE 0CA0 75CA 0CA0 0029 30CE 5F61 253B 2501 253B")` + +There are many ways to get a hex code, but an easy one is [this site](https://r12a.github.io/app-conversion/). Just make sure to convert to hexadecimal, and that is your string. + # Additional Language Support In `quantum/keymap_extras/`, you'll see various language files - these work the same way as the alternative layout ones do. Most are defined by their two letter country/language code followed by an underscore and a 4-letter abbreviation of its name. `FR_UGRV` which will result in a `ù` when using a software-implemented AZERTY layout. It's currently difficult to send such characters in just the firmware. diff --git a/quantum/process_keycode/process_unicode_common.c b/quantum/process_keycode/process_unicode_common.c index 7f34ad57c..e6620b7ea 100644 --- a/quantum/process_keycode/process_unicode_common.c +++ b/quantum/process_keycode/process_unicode_common.c @@ -16,6 +16,8 @@ #include "process_unicode_common.h" #include "eeprom.h" +#include <string.h> +#include <ctype.h> static uint8_t input_mode; uint8_t mods; @@ -120,3 +122,29 @@ void register_hex(uint16_t hex) { unregister_code(hex_to_keycode(digit)); } } + +void send_unicode_hex_string(const char *str) +{ + if (!str) { return; } // Safety net + + while (*str) { + // Find the next code point (token) in the string + for (; *str == ' '; str++); + size_t n = strcspn(str, " "); // Length of the current token + char code_point[n+1]; + strncpy(code_point, str, n); + code_point[n] = '\0'; // Make sure it's null-terminated + + // Normalize the code point: make all hex digits lowercase + for (char *p = code_point; *p; p++) { + *p = tolower((unsigned char)*p); + } + + // Send the code point as a Unicode input string + unicode_input_start(); + send_string(code_point); + unicode_input_finish(); + + str += n; // Move to the first ' ' (or '\0') after the current token + } +} diff --git a/quantum/process_keycode/process_unicode_common.h b/quantum/process_keycode/process_unicode_common.h index 4d2b04fb3..814b60c57 100644 --- a/quantum/process_keycode/process_unicode_common.h +++ b/quantum/process_keycode/process_unicode_common.h @@ -31,6 +31,7 @@ uint8_t get_unicode_input_mode(void); void unicode_input_start(void); void unicode_input_finish(void); void register_hex(uint16_t hex); +void send_unicode_hex_string(const char *str); #define UC_OSX 0 // Mac OS X #define UC_LNX 1 // Linux |
