jinja2 static website template renderer

render.py

import shutil
import os
from jinja2 import Environment, FileSystemLoader

env = Environment(loader=FileSystemLoader('.'))

def renderFile(filename):
    origPath = "files/" + filename
    newPath = "output/" + filename
    template = env.get_template(origPath)
    output = template.render()
    with open(newPath, "wb") as fh:
        fh.write(output.encode('utf-8'))
    pass



if __name__ == "__main__":
    # copy all files from verbatim folder to output
    shutil.copytree("./verbatim", "./output", dirs_exist_ok=True)

    for subdir, dirs, files in os.walk("files"):
        for file in files:
            if file.endswith(".html"):
                print("rendering", file)
                renderFile(file)

Usage

The script is concerned with the following folders on the same directory:

• the output folder is where the final result is copied to
• the contents of the verbatim folder is copied 1:1 to output
• all .html files in the files folder gets rendered with jinja and copied to output

Personally in the main directory I have a template and then each html file in files simply extends it. This saves me (and you) from needlessly having to copy header, footer and scripts into every single subpage, keeping it all DRY. Static website with template rendering made easy!
