Overview

learningfoundry takes a single curriculum.yml file and generates a fully self-contained SvelteKit learning application. The generated app supports:

• Text — Markdown content rendered in the browser
• Video — YouTube embeds
• Quiz — Interactive assessments via quizazz (optional)
• Exercise — Executable notebooks via nbfoundry (stub provided)
• Visualization — D3-based charts via d3foundry (stub provided)

Learner progress is persisted locally in SQLite (via sql.js) — no backend required.

---

Installation

pip install learningfoundry

With optional quizazz support:

pip install "learningfoundry[quizazz]"

Requirements:

• Python 3.12+
• pnpm (for preview command and generated app development)
• Node.js 18+ (for the generated SvelteKit app)

---

Quick Start

1. Create a curriculum file (see Curriculum YAML Format):

   cat > curriculum.yml << 'EOF'
   version: "1.0.0"
   curriculum:
     title: "My Course"
     description: "A short description."
     modules:
       - id: mod-01
         title: "Module One"
         lessons:
           - id: lesson-01
             title: "Getting Started"
             content_blocks:
               - type: text
                 ref: content/lesson-01.md
               - type: video
                 url: "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
   EOF
   

2. Validate the curriculum:

   learningfoundry validate
   # OK — curriculum is valid.
   

3. Build the SvelteKit app:

   learningfoundry build
   # Build complete → dist/
   

4. Preview locally (builds then starts a dev server):

   learningfoundry preview
   # Preview server started at http://localhost:5173

  --help                  Show this message and exit.

Prints OK — curriculum is valid. on success, or a list of errors and exits with code 1.

learningfoundry preview

Build then launch a local Vite dev server.

Usage: learningfoundry preview [OPTIONS]

Curriculum YAML Format

version: "1.0.0"

curriculum:
  title: "Course Title"           # required
  description: "Course overview." # optional

  modules:
    - id: mod-01                  # required, kebab-case
      title: "Module One"         # required
      description: "..."          # optional

      # Optional pre/post assessments (requires quizazz-builder)
      pre_assessment:
        source: quizazz
        ref: assessments/mod-01-pre.yml

      post_assessment:
        source: quizazz
        ref: assessments/mod-01-post.yml

      lessons:
        - id: lesson-01           # required, kebab-case; unique within module
          title: "Lesson One"     # required

          content_blocks:

            # Text block — Markdown file
            - type: text
              ref: content/mod-01/lesson-01.md

            # Video block — YouTube URL only
            - type: video
              url: "https://www.youtube.com/watch?v=XXXXXXXXXXX"

            # Quiz block — requires learningfoundry[quizazz]
            - type: quiz
              source: quizazz
              ref: assessments/mod-01-quiz.yml

            # Exercise block — requires nbfoundry (stub included)
            - type: exercise
              source: nbfoundry
              ref: exercises/mod-01-exercise.yml

            # Visualization block — requires d3foundry (stub included)
            - type: visualization
              source: d3foundry
              ref: visualizations/mod-01-vis.yml

Rules:

• Module and lesson id values must be unique within their scope, and match the pattern [a-z0-9][a-z0-9-]*.
• Every curriculum must have at least one module; every module at least one lesson.
• All ref paths are resolved relative to --base-dir (default: directory containing the curriculum YAML).
• Only YouTube URLs are accepted for video blocks (youtube.com/watch?v= or youtu.be/).

---

Configuration File

An optional config file can set defaults for logging. The CLI always takes precedence.

Default location: ~/.config/learningfoundry/config.yml

logging:
  level: INFO      # DEBUG | INFO | WARNING | ERROR
  output: stdout   # stdout | stderr

Pass a custom config location with -c / --config.

• pnpm 9+ and Node.js 18+

Setup

git clone https://github.com/pointmatic/learningfoundry.git
cd learningfoundry

# Create the Python environment and install the package in editable mode
pyve init
pip install -e .

# Create the test runner environment and install dev dependencies
pyve testenv --init
pyve testenv --install -r requirements-dev.txt

Running Tests

# Fast unit + integration tests (~2 min)
pyve test

# End-to-end SvelteKit smoke tests (requires pnpm, ~15 s extra)
pyve test tests/test_smoke_sveltekit.py -v

Linting and Type Checking

pyve testenv run ruff check .
pyve testenv run mypy src/
