mini-svg 1.1.8

Educational SVG generation library for learning programming with Python.

mini-svg

mini-svg is a lightweight educational Python library for generating SVG graphics using simple programming constructs.

It is designed for classrooms and beginner-friendly workshops where students can:

• write Python code,
• generate an .svg file,
• open it in Inkscape,
• and immediately see the visual result.

Why SVG?

SVG is a standard vector format:

• readable as text,
• editable in tools like Inkscape,
• ideal for “code → visual output” feedback loops.

Small code changes produce immediate visual differences, which makes it perfect for teaching programming concepts.

---

Features

• Zero dependencies (Python standard library only)
• Progressive learning levels
• Flat API for simplicity
• Explicit modular API for classroom restriction
• Clean packaging (pyproject-based)
• Version read dynamically from package metadata

---

Installation (recommended)

Using venv + pip

Create a virtual environment:

python -m venv .venv
source .venv/bin/activate     # Windows: .venv\Scripts\activate
pip install -U pip
pip install -e .

Test the installation:

python -c "import mini_svg as minisvg; print(minisvg.__version__)"

---

Alternative: using pipenv

If you prefer pipenv:

pipenv install -e .
pipenv shell

This is optional. The project does not require pipenv.

---

Quick Start (Flat API — Recommended)

The simplest way to use the library:

import mini_svg as minisvg

parts = [minisvg.svg_begin(400, 300)]
parts.append(minisvg.circle(200, 150, 80, fill="red"))
parts.append(minisvg.svg_end())

minisvg.save_svg("demo.svg", parts)

Open demo.svg in Inkscape.

This flat API exposes the full (advanced) feature set.

---

Progressive Levels (Classroom Mode)

If you want to restrict students to a specific level, import one of:

• minisvg_basic
• minisvg_intermediate
• minisvg_advanced

---

Level 1 — minisvg_basic

Includes:

• svg_begin()
• svg_end()
• save_svg()
• line()
• rect()
• circle()

Example:

from mini_svg import minisvg_basic

parts = [minisvg_basic.svg_begin(400, 300)]
parts.append(minisvg_basic.circle(200, 150, 80))
parts.append(minisvg_basic.svg_end())

minisvg_basic.save_svg("basic.svg", parts)

Recommended for beginners learning:

• Functions
• Parameters
• Simple geometry
• File writing

---

Level 2 — minisvg_intermediate

Includes everything from Level 1, plus:

• text()
• group()
• regular_polygon()
• star()
• cubic_bezier()

Example:

from mini_svg import minisvg_intermediate

parts = [minisvg_intermediate.svg_begin(500, 300)]
parts.append(minisvg_intermediate.star(5, (150, 50, 200, 200), fill="gold"))
parts.append(minisvg_intermediate.text(20, 30, "Hello SVG!", font_size=24))
parts.append(minisvg_intermediate.svg_end())

minisvg_intermediate.save_svg("intermediate.svg", parts)

Recommended for students comfortable with:

• Loops
• Math functions
• Coordinate transformations

---

Level 3 — minisvg_advanced

Includes everything from Level 2, plus:

• bezier_path_cubic()

Example:

from mini_svg import minisvg_advanced

parts = [minisvg_advanced.svg_begin(600, 300)]

start = (50, 150)
segments = [
    (150, 50, 250, 250, 350, 150),
    (400, 100, 500, 200, 550, 150),
]

parts.append(minisvg_advanced.bezier_path_cubic(start, segments, stroke="black", stroke_width=3))
parts.append(minisvg_advanced.svg_end())

minisvg_advanced.save_svg("advanced.svg", parts)

Recommended for advanced students working with:

• Lists of tuples
• Structured data
• SVG <path> syntax
