Project description

`tagz`

tagz – is an extremely simple library for building html documents without using templates, just with python code.

from tagz import Page, StyleSheet, Style, html


page = Page(
    lang="en",
    body_element=html.body(
        html.h1("Hello"),
        html.div(
            html.strong("world"),
        ),
        html.a(
            "example link",
            html.i("with italic text"),
            href="https://example.com/"
        ),
    ),
    head_elements=(
        html.meta(charset="utf-8"),
        html.meta(name="viewport", content="width=device-width, initial-scale=1"),
        html.title("tagz example page"),
        html.link(href="/static/css/bootstrap.min.css", rel="stylesheet"),
        html.script(src="/static/js/bootstrap.bundle.min.js"),
        html.style(
            StyleSheet({
                "body": Style(padding="0", margin="0"),
                (".container", ".container-fluid"): Style(transition="opacity 600ms ease-in"),
            })
        )
    ),
)

# `pretty=False` should be faster but performs not a human-readable result
print(page.to_html5(pretty=True))

writes something like this:

<!doctype html>
<html lang="en">
	<head>
		<meta charset="utf-8"/>
		<meta name="viewport" content="width=device-width, initial-scale=1"/>
		<title>
			tagz example page
		</title>
		<link href="/static/css/bootstrap.min.css" rel="stylesheet"/>
		<script src="/static/js/bootstrap.bundle.min.js">
		</script>
		<style>
			body {padding: 0; margin: 0;}
			.container, .container-fluid {transition: opacity 600ms ease-in;}
		</style>
	</head>
	<body>
		<h1>
			Hello
		</h1>
		<div>
			<strong>
				world
			</strong>
		</div>
		<a href="https://example.com/">
			example link
			<i>
				with italic text
			</i>
		</a>
	</body>
</html>

        })
    )
)

More examples

Building page from parts

You can reuse the code, and assemble the page piece by piece, to do this you can modify elements already added to the tags:

from tagz import html, Page

# Make an content element
content = html.div(id='content')

page = Page(
    lang="en",
    body_element=html.body(
        html.h1("Example page"),
        html.hr(),
        # Adding it to the page
        content,
    ),
    head_elements=(
        html.meta(charset="utf-8"),
        html.title("tagz partial page"),
    ),
)

content.append("Example page content")

print(page.to_html5(pretty=True))

This prints something like this:

<!doctype html>
<html lang="en">
	<head>
		<meta charset="utf-8"/>
		<title>
			tagz example page
		</title>
	</head>
	<body>
		<h1>
			Example page
		</h1>
		<hr/>
		<div id="content">
			Example page content
		</div>
	</body>
</html>

Convert CSV to html table

from io import StringIO
from urllib.request import urlopen
from csv import reader
from tagz import html, Page, Style

url = (
    'https://media.githubusercontent.com/media/datablist/'
    'sample-csv-files/main/files/organizations/'
    'organizations-10000.csv'
)

csv = reader(StringIO(urlopen(url).read().decode()))
table = html.table(border='1', style=Style(border_collapse="collapse"))
content = list(csv)

# Make table header 
table.append(html.tr(*map(html.th, content[0])))

# Add table rows
for csv_row in content[1:]:
    table.append(html.tr(*map(html.td, csv_row)))

page = Page(
    lang="en",
    body_element=html.body(
        html.h1("Converted CSV"),
        table,
        "Content of this page has been automatically converted from",
        html.a(url, href=url),
    ),
    head_elements=(
        html.meta(charset="utf-8"),
        html.title("tagz csv example page"),
    ),
)

with open("/tmp/csv.html", "w") as fp:
    fp.write(page.to_html5())
