+
+## About
+This Python 3 script, by [Tsan-Kuang Lee](https://github.com/tsankuanglee) takes the keymap.c downloaded from [ErgoDox EZ Configurator](https://configure.ergodox-ez.com/) and beautifies it for easier customization, allowing one to quickly draft a layout to build upon.
+
+## Features
+For example, the original `keymap.c` looks like
+
+```
+[0] = LAYOUT_ergodox(KC_EQUAL,KC_1,KC_2,KC_3,KC_4,KC_5,LCTL(KC_MINUS),KC_DELETE,KC_Q,KC_W,KC_E,KC_R,KC_T,KC_LBRACKET,KC_BSPACE,KC_A,KC_S,KC_D,KC_F,KC_G,KC_LSPO,CTL_T(KC_Z),KC_X,KC_C,KC_V,KC_B,ALL_T(KC_NO),LT(1,KC_GRAVE),KC_QUOTE,LALT(KC_LSHIFT),KC_LEFT,KC_RIGHT,ALT_T(KC_APPLICATION),KC_LGUI,KC_HOME,KC_SPACE,KC_UNDS,KC_END,LCTL(KC_EQUAL),KC_6,KC_7,KC_8,KC_9,KC_0,KC_MINUS,KC_RBRACKET,KC_Y,KC_U,KC_I,KC_O,KC_P,KC_BSLASH,KC_H,ALT_T(KC_J),KC_K,KC_L,LT(2,KC_SCOLON),GUI_T(KC_QUOTE),MEH_T(KC_NO),KC_N,KC_M,KC_COMMA,KC_DOT,CTL_T(KC_SLASH),KC_RSPC,KC_UP,KC_DOWN,KC_LBRACKET,KC_RBRACKET,TT(1),KC_LALT,CTL_T(KC_ESCAPE),KC_PGUP,KC_PGDOWN,LT(1,KC_TAB),KC_ENTER),
+```
+
+The beautifier parses it and outputs:
+
+```
+[0] = LAYOUT_ergodox(
+// left hand
+
+KC_EQUAL , KC_1 , KC_2 , KC_3 , KC_4 , KC_5, LCTL(KC_MINUS),

+
+// left thumb
+
+ ALT_T(KC_APPLICATION), KC_LGUI,

+KC_SPACE, KC_UNDS , KC_END ,

+
+// right thumb
+
+KC_LALT , CTL_T(KC_ESCAPE),
+KC_PGUP ,
+KC_PGDOWN, LT(1,KC_TAB) , KC_ENTER
+)
+```
+
+Optionally, it can also render [LAYOUT_ergodox_pretty](https://github.com/qmk/qmk_firmware/blob/ee700b2e831067bdb7584425569b61bc6329247b/keyboards/ergodox_ez/keymaps/bpruitt-goddard/keymap.c#L49-L57):

+
+## Usage
+
+### With docker
+This is the cleaner way. `Docker` is the only requirement. The program executes within a container that has all dependencies installed.
+
+First build the images. (Run once)
+```
+cd QMK_GIT_REPO_dir/keyboards/ergodox_ez/util/keymap_beautifier
+docker build -t keymapbeautifier:1.0 .
+```
+Run it
+```
+cd QMK_GIT_REPO_dir/keyboards/ergodox_ez/util/keymap_beautifier
+cp PATH_TO_YOUR_C_SOURCE_FILE.c input.c
+./docker_run.sh input.c -p -c -o output.c
+```
+The prettified file is written to `output.c`. See the section Tweaks for non-default settings.
+
+### Without docker
+Requirements:
+* python3 (tested on 3.7.4)
+* python module `pycparser` installed (with `pip install pycparser`)
+
+To run:
+```
+cd QMK_GIT_REPO_dir/keyboards/ergodox_ez/util/keymap_beautifier
+cp PATH_TO_YOUR_C_SOURCE_FILE.c input.c
+./KeymapBeautifier.py input.c -p -c -o output.c
+```
+The prettified file is written to `output.c`. See the section Tweaks for non-default settings.
+
+## Tweaks
+```
+usage: KeymapBeautifier.py [-h] [-o OUTPUT_FILENAME] [-p] [-c] input_filename
+
+Beautify keymap.c downloaded from ErgoDox-Ez Configurator for easier
+customization.
+
+positional arguments:
+ input_filename input file: c source code file that has the layer
+ keymaps
+
+optional arguments:
+ -h, --help show this help message and exit
+ -o OUTPUT_FILENAME, --output-filename OUTPUT_FILENAME
+ output file: beautified c filename. If not given,
+ output to STDOUT.
+ -p, --pretty-output-layout
+ use LAYOUT_ergodox_pretty for output instead of
+ LAYOUT_ergodox
+ -c, --justify-toward-center
+ for LAYOUT_ergodox_pretty, align right for the left
+ half, and align left for the right half. Default is
+ align left for both halves.
+```
+For example,
+```
+./docker_run.sh input.c -p -c -o output.c
+# or if you don't want to use docker:
+#./KeymapBeautifier.py input.c -p -c -o output.c
+```
+will read `input.c`, and produce `output.c` with LAYOUT_ergodox_pretty, and have the key symbols gravitating toward the center.
