## Overview

#### Purpose and Operating Model
WebLatex is a repository template for authoring LaTeX documents in GitHub Codespaces/VS Code rather than a standalone web application. It combines a containerized TeX environment with VS Code extensions for editing, compilation, PDF preview, Git workflows, AI assistance, language checking, and collaboration.

#### Entry Points
- `demo.tex` is the included LaTeX document and primary authoring/compilation input.
- `.devcontainer/devcontainer.json` is the operational entry point: Codespaces/dev-container creation reads it to provision the runtime, editor extensions, and LaTeX Workshop behavior.
- `README.md` defines the intended user flow: create a repository from the template, open a Codespace, then edit and save `.tex` files.

#### Development Container Runtime
The dev container is the core deployment unit, not application code. `.devcontainer/devcontainer.json` selects/configures a TeX Live-capable environment and VS Code settings. It is expected to provide the full LaTeX toolchain, including support for alternate engines selected through TeX magic comments in source documents.
Relevant paths: `.devcontainer/devcontainer.json`, `.devcontainer/devcontainer.json`.

#### Authoring and Compilation Pipeline
A user edits a `.tex` source file such as `demo.tex`; VS Code autosave/save events trigger LaTeX Workshop compilation. The extension selects the configured or source-declared TeX engine, invokes TeX Live in the container, emits compiler diagnostics to VS Code, and writes generated PDFs to the configured output directory (documented as `/PDF` by default).
Relevant paths: `demo.tex`, `.devcontainer/devcontainer.json`.

#### PDF Preview and Editor Feedback
LaTeX Workshop supplies editor-facing features—live PDF preview, errors/logs, formatting, linting, citations/references, and dark-mode PDF rendering. Configuration in the dev container controls output path, compile behavior/delay, and viewer colors; this makes editor settings part of the repository’s architecture.
Relevant paths: `.devcontainer/devcontainer.json`, `demo.tex`.

#### Collaboration and External Services
The environment integrates external VS Code services via extensions configured in `.devcontainer/devcontainer.json`:
- GitHub Codespaces provides the hosted development runtime; Git/GitHub provide version control and repository sharing.
- GitHub Copilot supplies in-editor completion.
- Grammarly is enabled for writing assistance; LanguageTool is an optional alternative.
- Visual Studio Live Share enables real-time collaboration.
These are client/editor integrations rather than repository-hosted backend services.

#### Extension and Customization Boundary
Users customize document content in `.tex` files and environment behavior in `.devcontainer/devcontainer.json`. The template intentionally keeps infrastructure declarative and document-first: there is no server source, frontend source, package manifest, or application API in the repository tree. `LICENSE` establishes reuse terms; `README.md` is the operational guide.
Relevant paths: `demo.tex`, `.devcontainer/devcontainer.json`, `LICENSE`.

Main entry points: [`.devcontainer/devcontainer.json`](https://github.com/balajicm24/weblatex/blob/main/.devcontainer/devcontainer.json) (Dev container config), [`README.md`](https://github.com/balajicm24/weblatex/blob/main/README.md) (Usage guide), [`LICENSE`](https://github.com/balajicm24/weblatex/blob/main/LICENSE) (Reuse terms), [`demo.tex`](https://github.com/balajicm24/weblatex/blob/main/demo.tex) (LaTeX document)
