App.tsx Modularization Refactor

• Refactored large UI sections out of src/App.tsx into focused components:
  • src/components/AppHero.tsx
  • src/components/AutomatonEditorPanel.tsx
  • src/components/AutomatonVisualizationPanel.tsx
• Updated src/App.tsx to act as an orchestration layer for state + handlers while delegating render blocks to the new components.
• Added shared handler helpers in src/App.tsx to reduce repeated per-automaton update logic:
  • updateSelectedUiState
  • handleSimulationInputChange
  • handlePreviousStep
  • handleNextStep
  • handlePauseAutoPlay
• Consolidated simulation panel props into a single simulationPanelProps object passed to the visualization component.
• Switched App declaration to React.FC typing for consistency with the extracted components.
• Added functionality to other Automata types and made the sim work properly

DFA Simulation UI Integration

• Connected parsed Deterministic Finite Automaton definitions to simulateDFA in src/App.tsx.
• Added simulation input controls (input string + Run).
• Added simulation result output:
  • Accept/Reject status
  • final state
  • simulation/validation errors (when present)
• Added related simulation styles in src/App.css.
• Updated TODO to mark immediate Step 5 complete.

TODO Clarification

• Added explicit Simulation UI task: Allow simulating step by step.
• Next immediate implementation target: TODO Step 6 (interactive step runner).

Validation Runs

• pnpm lint passed
• pnpm test passed

Project Setup and Foundation

• Initialized project foundation tasks from TODO Section 1.
• Replaced starter Vite/React counter UI with an AutomataSim shell.
• Added base project documentation and local/deploy instructions in README.md.
• Created base source structure:
  • src/components/
  • src/lib/
  • src/types/

CI / Deployment Fix

• Investigated GitHub Actions failure at actions/setup-node@v4 with pnpm cache.
• Root cause: pnpm-workspace.yaml existed without a required packages field.
• Fix applied:
  • Added:
    • packages:
    • - .
• Verified command success locally:
  • pnpm store path --silent
  • pnpm install --frozen-lockfile

Scope and Terminology

• Completed TODO Section 2 (MVP scope definition).
• Set MVP automaton scope to Deterministic Finite Automaton only.
• Standardized wording to use full automata names instead of acronyms in TODO/app text.

Text-Based Automaton Input + Rendering

• Switched approach from field-by-field editor to text-based automaton definition input.
• Added new types in src/types/automaton.ts.
• Added parser/validator in src/lib/parseAutomaton.ts:
  • Parses states, alphabet, start, accept, and transitions.
  • Validates missing sections, invalid references, duplicates, and transition format.
• Rebuilt UI in src/App.tsx:
  • Textarea input for definition.
  • Live parse error output.
  • SVG rendering of states and transitions.
  • Start arrow and accepting-state double-circle rendering.
• Added supporting styles in src/App.css.

Validation Runs

• pnpm install passed
• pnpm dev started successfully
• pnpm lint passed
• pnpm build passed

Next Planned Work

• Implement Deterministic Finite Automaton simulation engine (simulateDFA).
• Add input string execution (accept/reject + step trace).

this project already has some features, but for now it’s only local files on your android device

the calculator CLI is now fully working, tomorrow ill probably try to make it an app instead of a cli interface

I have working on this for about an hour and a half, I have learned a lot about Rust, but for now it is still command line
