Squel's QMK keymap for the GMMK Pro (rev1/ansi)

Compile and flash instructions

Prerequisites:

• qmk cli and compiler dependancies
• qmk_firmware repository
  • git clone --recurse-submodules https://github.com/qmk/qmk_firmware, optionally specify --depth 1

git clone https://codeberg.org/squel/qmk
ln -s path/to/keymap ~/qmk_firmware/keyboards/gmmk/pro/rev1/ansi/keymaps/custom
cd qmk_firmware
# qmk compile -kb gmmk/pro/rev1/ansi -km custom -j 16 # just compile
qmk flash -kb gmmk/pro/rev1/ansi -km custom -j 16 # compile & flash

# optional, some magic to make clang/intellisense behave :P
bear -- qmk compile -kb gmmk/pro/rev1/ansi -km custom -j 16

Alternative Docker build:

git clone https://codeberg.org/squel/qmk
cd qmk
docker compose up --build # note that the keymap is copied during docker's image build
