MiKTeX is a comprehensive, cross-platform TeX distribution that provides a complete typesetting system for Windows, macOS, and Linux. The repository contains the source code for TeX engines (pdfTeX, XeTeX, LuaTeX, e-upTeX, etc.), companion tools (dvipdfmx, dvisvgm, asymptote, metapost, tex4ht, etc.), the TeXworks editor, and the MiKTeX package manager (Console) and DVI viewer (Yap). It also bundles a large number of third-party libraries (FreeType, HarfBuzz, Poppler, LibreSSL, cURL, GMP, MPFR, etc.) as vendored dependencies. The architecture is monolithic: each executable compiles independently but shares a common core library (MiKTeX Core) that provides session management, file I/O, package management, and platform abstraction. The primary data flow is user-driven: packages are downloaded from remote repositories, TeX documents are compiled via one of the engines producing DVI or PDF output, and fonts are handled via system or bundled resources. The codebase is actively maintained with frequent releases, but the reliance on many vendored libraries and extensive platform-specific `#ifdef` blocks introduces moderate technical drift risk.
