Clean /tmp/TinyTorch before EACH GIF generation, not just once at the start.
VHS executes real commands and captures actual output, so if /tmp/TinyTorch exists from a previous GIF, the git clone will fail with 'already exists' error.
Now each GIF gets a clean environment:
🧹 Cleaning /tmp/TinyTorch for this GIF...
This ensures GIF 01 shows successful clone on every generation.
Test script now measures actual execution time for every command using Python's time.time(), outputting recommendations to /tmp/tinytorch_timing.txt.
Measured timings:
- git clone: 3s (varies by network, using safe 3s)
- setup-environment.sh: 9s (measured 8.6s)
- tito system health: 0.5s (show for 3s for readability)
- tito module status: 0.2s (show for 3s)
- tito logo: 0.1s (show for 6s)
Updated 01-zero-to-ready.tape with measured delays to ensure:
- GIF shows actual command completion
- No typing ahead before previous command finishes
- Realistic demo of student experience
This fixes the issue where VHS would type commands faster than they execute.
Students should see the clean first-time workflow, not our test infrastructure.
Changes:
- VHS tape: Shows 'cd /tmp' then 'git clone' (no rm -rf)
- generate.sh: Cleans /tmp/TinyTorch BEFORE running VHS
- test_demo_workflow.sh: Already cleaned before testing
- README: Documents the separation of concerns
This presents the ideal student experience while maintaining reproducibility:
- Students: See clean setup flow (cd → clone → setup)
- Scripts: Handle cleanup behind the scenes
- Tests: Validate fresh environment every time
GIF size: 494KB → 467KB (optimized further)
Document the improved demo testing and generation workflow:
- Explains test_demo_workflow.sh purpose and usage
- Describes cleanup strategy to prevent 'directory exists' errors
- Provides troubleshooting guide for common issues
- Documents best practices for updating demo commands
- Maps file locations and workflow architecture
This ensures future demo updates maintain quality and accuracy.
- Create comprehensive test script for demo workflow validation
- Clean /tmp/TinyTorch before cloning to avoid conflicts
- Test full workflow: clone, setup, tito commands
- Update VHS tapes with proper cleanup steps
- Fix command names (tito status -> tito module status)
- Regenerate all 4 demo GIFs with corrected commands
- Log all test output for validation
