* Made DZ60 layout with calculator
* Cleaned up and commented, preparing to fix bug with negative in front of open parenthesis as first character
* Fixed bug where negative sign infront of parenthesis as first character was parsed incorrectly
* Made a better solution for the bug from the previous commit
* Modularized and added a userfile so that this code can be used on various keyboards, found in doogle999
* Removed commented code from keymap
* Made the layer that is used for calculations a define so that it can be changed per keyboard
* Made the readme
* Made the readme in the correct place
* Revert "Made the readme in the correct place"
This reverts commit 7f8b59ed9e.
* Manually synced with qmk upstream
* Stopped repeat, made keys print character that they are defined as rather than what the keyboard wants them to do
* Added support for numpad, might make all keycodes custom so that there is no need to change doogle999.c if you want to change the keycode that is associated with a function, also made numpad automatically activating an option
* Fixed some bugs with backspacing, updated the readme
* Fixed some bugs with numlock turning on at the wrong times when a shift key was down
* Made the return to layer work automatically instead of just forcing it to layer 0
* fixes and style changes, 20% decreased binary size
* Fixed some bugs with double printing and compilation errors on my side
* Fixed bug with exceeding the buffer size
* Removed changes that added const-ness
* Made changes so that backspace does not repeat to remove backspace bugs, still some bugs with recalculating without having typed anything
* Fixed obo error with calc main loop
* Made includes more accurate in keymap for dz60
* Moved flags to user makefile
