Prototype command line script to convert ai2html output to valid React

ai2html2react.py

import sys
import os 
import re

dir_path = os.path.dirname(os.path.realpath(__file__)) + '/'

static_content_folder = 'static/custom/ai2html-output/'

# script takes two arguments "input" and "output" and optional static content folder arg
# .js extension is added to output
# check if there are any arguments, else exit.

if len(sys.argv)>1:

    # ignore script name
    args = sys.argv[1:]
    for arg in args:
        print(arg)

    print(dir_path)

    INPUT = args[0]
    OUTPUT = args[1]
    # if we pass a folder argument
    try:
        static_content_folder = args[2]
    except:
        pass

    # start and end strings
    react_start = "// converted from "  + INPUT + "\n\n\nimport React from 'react'\nexport default ({ props }) => (\n\n    <div className='container'>\n\n"

    react_end = "\n    </div>\n  )"


    # here we put replacements: 
    # 0-1 comments, 
    # 2-3 style def
    # 4 className
    replacements = [
        ('<!--','{/*'), 
        ('-->','*/}'),
        ("<style type='text/css' media='screen,print'>"
    , "<style jsx type='text/css' media='screen,print'>{`"),
        ("</style>", "`}</style>"),
        ('class', 'className')]

    text = open(dir_path + INPUT).read()

    text_new = text

    for r in replacements:
        text_new = text_new.replace(*r)

    # split string into two parts, style defs and contents
    parts = re.split('(</style>)', text_new)
    style_defs = parts[0] + parts[1]

    divs = parts[2]


    # quote inline style defs 
    divs = re.sub('(?<=style\=)"([a-z\,0-9\s\-\.%\(\):;]+)"', '{{\g<1>}}', divs )


    divs = re.sub('(?<=:)([a-z\,0-9\s\-\.%\(\)]+);', '"\g<1>", ', divs)

    divs = re.sub('\s-(\w)',' \g<1>' , divs)


    callback = lambda pat: pat.group(1).upper()

    divs = re.sub('-(\w)(?=[\w\-]+:)',callback , divs)

    divs = re.sub('src="', 'src="'+ static_content_folder, divs )

    content = react_start + style_defs + divs +react_end
    print(content)


    f= open(dir_path + args[1] +'.js',"w+")

    f.write(content)

    f.close()

else: print("please provide names of input and output files: ai2html2react.py -input -output")

Super helpful script. One small issue I've found is that it replaces instances of the word "class" in text blocks with "className."
