Timer Quick Start

Build & Run

Using Makefile:

make -B
./timer [time] [options]

Without Makefile:

mkdir -p build
gcc -Wall -Wextra -ggdb src/png2c.c -o build/png2c -lm
build/png2c assets/digits.png digits > src/digits.h
build/png2c assets/penger_walk_sheet.png penger > src/penger_walk_sheet.h
gcc -Wall -Wextra -ggdb src/main.c -o timer -lX11 -lXrandr -lGL -lm

If no time is provided, the timer defaults to stopwatch mode. Time format: 1h2m3s (hours, minutes, seconds). Options include starting paused or auto-exit on completion.
