Animation — CSS/SVG Animation Code Generator#

Generate production-ready CSS keyframe animations, SVG motion paths, transitions, and easing functions from the command line. Animations are stored locally in JSONL format for reuse, chaining, and export.

Prerequisites#

• Python 3.6+
• Bash 4+

Data Storage#

All animation records are persisted to ~/.animation/data.jsonl. Each record is a JSON object with fields like id, name, type, code, created_at, etc.

Commands#

Run via: bash scripts/script.sh <command> [options]

Usage Examples#

bash

# Create a fade-in animation
bash scripts/script.sh create --name fadeIn --type css --property opacity --from 0 --to 1 --duration 0.5s

# Generate keyframes
bash scripts/script.sh keyframe --name bounce --steps '0%:translateY(0);50%:translateY(-20px);100%:translateY(0)'

# Create a transition
bash scripts/script.sh transition --property transform --duration 0.3s --easing ease-in-out

# List all saved animations
bash scripts/script.sh list

# Preview an animation in HTML
bash scripts/script.sh preview --name fadeIn

# Export animations to a CSS file
bash scripts/script.sh export --name fadeIn --format css --output animations.css

# Chain two animations
bash scripts/script.sh chain --names fadeIn,bounce --delay 0.2s

# Show available easing functions
bash scripts/script.sh easing --list

# Set loop count
bash scripts/script.sh loop --name bounce --count infinite

# Build a multi-step sequence
bash scripts/script.sh sequence --names fadeIn,bounce --mode sequential

Output Format#

All commands output to stdout. Structured data is returned as JSON. Generated code is printed as raw CSS or SVG text suitable for copy-paste or piping.

Notes#

• Animation IDs are auto-generated UUIDs.
• The preview command creates a self-contained HTML file that can be opened in any browser.
• chain and sequence reference animations by name; they must exist in the data store.
• export --format svg wraps animations in an <svg> + <animate> / <animateTransform> structure.
