PyTempl

Build HTML user interfaces in Python.

Introduction

PyTempl is a DSL that lets you build HTML components as Python objects, offering a clean, component-based approach that avoids the complexities of traditional templating engines. Create reusable components that generate HTML fragments to build complex views, pages, or even entire web applications, all within your Python workflow.

Getting Started

Installation:

pip install pytempl  

Simple Example:

from pytempl.tags.html import H1, Div, P
from pytempl import render

page = Div(_class="container")(
    H1()("My Awesome Page"),
    P()("This is a paragraph of text.")
)

print(render(page))

This will output neatly formatted HTML.

Advanced Example 1: Dynamic Content and Components

from pytempl.tags.html import Li, Span, Ul
from pytempl import render

items = ["apple", "banana", "cherry"]
item_list = Ul()(Li()(item) for item in items)

name = "Alice"
greeting = Span()(f"Hello, {name}!")

print(render(Div()(greeting, item_list)))

This demonstrates creating dynamic content and nesting components. The output will be an HTML <div> containing a greeting and the unordered list of fruits.

Advanced Example 2: HTMX Support

from pytempl.tags.html import Div, Button, Img
from pytempl import render

click_to_load = Div(id="replace_me")(
    Button(
        _class="btn primary",
        hx_get="/example/?data=1",
        hx_target="#replace_me",
        hx_swap="outerHTML",
    )(
        "Load More Data...",
        Img(_class="htmx-indicator", src="/img/bars.svg", alt="Loading..."),
    )
)

print(render(click_to_load))

Backwards Compatibility Note

This project is under active development and has not yet reached v1.0.0. This means that while we are working hard to build the best possible package, we may need to make changes that affect how your code works.

Version Stability:

• Minor Version Updates (e.g., 0.1.x -> 0.2.x): These updates may introduce breaking changes as we refine and improve the package's functionality and APIs.
• Patch Version Updates (e.g., 0.1.1 -> 0.1.2): These updates will maintain compatibility within the same minor version and generally include bug fixes or small enhancements.

To avoid unexpected disruptions, it is recommended to pin your dependency to a specific minor version (v0.x) and carefully review release notes before upgrading to a new minor version.

We appreciate your understanding and welcome feedback as we work towards a stable and robust v1.0.0!
