Move tex files and compiles them in a temp dir, then move pdf file to root. Works on linux and requires nodemon and latexmk

tex.py

#!/usr/bin/env python3
import argparse
import os
from tempfile import mkdtemp

parser=argparse.ArgumentParser()
parser.add_argument("input",type=str)
args=parser.parse_args()
 
pwd=os.path.realpath(os.getcwd())

tmp_dir=mkdtemp(prefix="tex.py-")

out_pdf=os.path.splitext(os.path.split(args.input)[-1])[0] +".pdf"

with open(out_pdf,"w") as f:
	f.write("%PDF-1.0\n1 0 obj<</Pages 2 0 R>>endobj 2 0 obj<</Kids[3 0 R]/Count 1>>endobj 3 0 obj<</MediaBox[0 0 3 3]>>endobj\ntrailer<</Root 1 0 R>>")
os.system(f"evince {out_pdf}&")

cmds="&&".join([
	f'rsync -av . {tmp_dir} --exclude=".*"',
	f"cd {tmp_dir}",
	f"latexmk -pdf {args.input} ",
	f"cp {out_pdf} {pwd}/",
	f"cd {pwd}"
])
os.system(f"nodemon --exec '{cmds}' -e 'tex bib' .")

os.system("rm -rf {tmp_dir}")
