Online LaTeX Editor

This tool provides an online LaTeX editing and compilation environment designed for researchers, students, and academic writers. It solves the problem of coordinating authoring, compiling, and sharing LaTeX documents across teams without local tool installation. It supports articles, theses, and presentations and emphasizes reproducible builds.

Core Logic & Features: The system manages document structure (preamble, document class, packages) and supports multiple compilers (pdflatex, xelatex, lualatex). Required features include real-time collaboration, incremental builds, error highlighting, package management, and version history. Optional features include templates library, citation management, build logs, and export to PDF or ZIP archives.

Inputs & Outputs: Inputs include source_text, document_class, preamble, packages (list), compiler_choice, output_format (pdf, dvi, log), and project_id. Outputs include compiled_pdf, compilation_log, and error/warning messages with line references, plus a per-project revision history.

Algorithms & Calculations: The tool parses LaTeX source, resolves dependencies, performs incremental builds, and maps compiler errors to source lines. It caches successful builds for large documents and uses UTF-8 handling, font fallbacks, and license-aware template resolution.

Error & Edge Cases: Missing \\begin{document} or invalid syntax triggers precise error messages with line numbers. Incompatible package versions, missing fonts, or external font/font package failures yield actionable fallbacks. If a dependency is unavailable, the system reports the issue and suggests alternatives.

Industry/Region & Localization: TeX Live baseline 2024; UTF-8 input; standard Latin and multilingual support; templates and packages follow common LaTeX licensing and regional citation styles; no currency or measurement localization beyond LaTeX defaults.

Assumptions & Exclusions: Not a word processor or WYSIWYG editor; editing is LaTeX-source based. It does not edit non-LaTeX content directly. Excludes proprietary fonts without license and does not provide publishing workflows beyond generation of LaTeX artifacts.
