Golf a TeX solution with tex-autogolfer (https://github.com/jared-hughes/tex-autogolfer), then submit to code.golf with golfc (https://github.com/jared-hughes/golfc). Requires those two dependencies, and a specific directory structure.

submit-tex.sh

#!/bin/bash
set -euo pipefail

if [[ $# -lt 1 ]]; then
  echo "Usage: submit-tex.sh [hole] [options]"
  echo "Example: ./submit-tex.sh ./src/fizz-buzz.tex"
  echo "Requires directory setup where all .tex files are in ./src."
  exit 1
fi

hole="$1"; shift
hole="${hole#*src/}"
hole="${hole%.tex}"

in="src/$hole.tex"
out="zout/$hole.tex"

~/tex-autogolfer/dist/cli.js "$@" "$in" > "$out"

printf "Bytes: %d [golfed from %d]\n" "$(wc --bytes < "$out")" "$(wc --bytes < "$in")"

golfc submit -i "$out" -l tex -h "$hole"
