So I recently saw this post here where this guy got absolutely wrecked for posting his shitty code here, and not gonna lie, that was pretty funny.

So here is my turn!

Since the most popular Python lib for minifying HTML (htmlmin) is way too slow, I decided to make my own and honestly I'm surprised how short it is. It can't be that simple right? It is also about 10x faster than htmlmin. I challenge you to break this code to produce incorrect HTML:

from html.parser import HTMLParser
import rjsmin
import rcssmin


class MinifyHTMLParser(HTMLParser):
    def __init__(self):
        super().__init__()
        self.minified_html = ""

    def handle_decl(self, decl: str) -> None:
        self.minified_html += f"<!{decl}>"

    def unknown_decl(self, data: str) -> None:
        self.minified_html += f"<!{data}>"

    def handle_pi(self, data):
        self.minified_html += f"<?{data}>"

    def handle_startendtag(self, tag, attrs):
        self.add_tag(tag, attrs, "/>")

    def handle_entityref(self, name):
        self.minified_html += f"&{name};"

    def handle_charref(self, name):
        self.minified_html += f"&#x{name};"

    def handle_starttag(self, tag, attrs):
        self.add_tag(tag, attrs, ">")

    # TODO Rename this here and in `handle_startendtag` and `handle_starttag`
    def add_tag(self, tag, attrs, end_tag):
        self.minified_html += f"<{tag}"
        for attr in attrs:
            self.minified_html += f' {attr[0]}'
            if attr[1] is not None:
                self.minified_html += f'="{attr[1]}"'
        self.minified_html += end_tag

    def handle_endtag(self, tag):
        self.minified_html += f"</{tag}>"

    def handle_data(self, data):
        if self.lasttag == "style":
            self.minified_html += minify_css(data).strip()
        elif self.lasttag == "script":
            self.minified_html += minify_js(data).strip()
        elif self.lasttag in ["textarea", "pre", "code"]:
            self.minified_html += data
        else:
            self.minified_html += data.strip()

parser = MinifyHTMLParser()
parser.feed(html_text)
return parser.minified_html
