#!/bin/sh
set -e

datecmd="date +%Y-%m-%d"

if [ -z "$1" ]; then
  printf "Post title: " >&2
  read -r title
else
  title="$1"
fi

file="$($datecmd)_$title.md"

if [ -f "$file" ]; then
  printf "Error: post '$file' already exists.\n" >&2
  exit 1
fi

${EDITOR:-nano} "$file"

im not sure why i made it since i could just look at what date it is and write it down manually in the file name, but i felt like doing that as a quick hack
