What is a .TeX file?
TEX is a TeX or LaTeX typesetting source file. TeX was created by Donald Knuth; LaTeX, the macro package most authors actually write in, came later from Leslie Lamport.
- Did you know
- Knuth created TeX in 1978, and it still typesets most of the world’s mathematics and physics papers.
- Since version 3, TeX’s version number has gained extra digits that creep towards π, signalling how stable it has become.
- Knuth designed the companion Metafont system alongside TeX to define the very shapes of its letters.
- What Analyser shows you
- Open lightweight document and markup formats as selectable page previews: Rich Text Format (RTF, control words stripped to readable prose), AbiWord (ABW), FictionBook e-books (FB2), Hangul HWPX, MHTML web archives (the saved HTML rendered with scripts removed) and Safari .webarchive saved pages (every frame rendered, so Word Online and webmail pages show their text, with the stored images in a grid), plus markup and typesetting source - DITA, TEI, JATS journal XML, reStructuredText, AsciiDoc, Org-mode, Textile, TeX/LaTeX and BibTeX - shown with every page selectable and copyable. Also opens the small sidecar files unpacked from 3MF and OOXML bundles: OPC relationship XML (.rels) and MD5 checksum text (.md5).
- Open a .TeX file
- Drag a .TeX file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
