4 What is LA Installing LA A computer program (language and interpreter) created by Donald Knuth in Knuth wrote the typesetting engine to explore potential of the digital printing equipment. He aimed to revert trend of deteriorating typographical quality that affected his own books and articles. Two main aims: highest quality and highest durability. 4 / 48 Miguel Vidal LA in a Nutshell

5 What is LA Installing LA as we use it today was released in 1982, with some slight enhancements added in 1989 (8-bit characters support). One of the most sophisticated digital typographical systems ( The greatest contribution in the printing world since Gutenberg ). Popular in academia, especially in mathematics, computer science, engineering, and physics. Open Source Software ( public domain dedication): but any modified version must not be called! 5 / 48 Miguel Vidal LA in a Nutshell

6 What is LA Installing LA understands about 300 low-level commands ( primitives ). Primitives are rarely used directly by users. The smallest unit of length handled by TeX is 0, mm! (scaled point, 1 mm = sp) Functionality is provided by format files (predumped memory images of after large macro collections have been loaded). 6 / 48 Miguel Vidal LA in a Nutshell

7 What is LA Installing LA Written in a literate programming language called Web. TRIP and TRAP tests ( conformance test ): portable, same output with all versions. The design was frozen (and dedicated to Public Domain) in October 1990 (v3.1* π, no new features, only bug fixes). 7 / 48 Miguel Vidal LA in a Nutshell

8 METAFONT LA Installing LA Font description language to describe characters (glyphs) algorithmically with geometrical equations. It uses Bézier curves (vector graphics). Also created by Knuth but not strictly part of. It is possible to use and L A without METAFONT. Adobe PostScript fonts may be used instead. 8 / 48 Miguel Vidal LA in a Nutshell

10 What is L A LA Installing LA Set of macros from primitives that abstracted away many of the complexities. A format originally developed by Leslie Lamport. It incorporates document styles for books, letters, slides, etc. The current version is L A 2e. L A is Open Source Software (LaTeX Project Public License - LPPL), OSI-compliant. 10 / 48 Miguel Vidal LA in a Nutshell

11 LA Installing LA How to pronounce and spell L A, L A, or LaTeX (ASCII), no Latex. Pronounced /látej/ or /látek/, no latex! It derives from the Ancient Greek: τ ɛχνη (tejné: skill, art, technique ) χ: Ji letter (voiceless velar fricative, as ojo or Bach ), Chi /kai/ in English. IPA (International Phonetic Alphabet): [x] phonem 11 / 48 Miguel Vidal LA in a Nutshell

13 Advantages LA Installing LA Control Quality Flexibility Portability Scalability Stability 13 / 48 Miguel Vidal LA in a Nutshell

14 Advantages (2) LA Installing LA Typesetting, not word processing (LibreOffice, MS Office, etc.). Accurate, precise output (device independent). It prevents formatting errors (by forcing to declare logical structure). Separate content and styling. 14 / 48 Miguel Vidal LA in a Nutshell

15 Advantages (3) LA Installing LA Modular (add-on packages), powerful and highly portable (text files). Easy to make global changes; encourage content reuse. Complex structures (footnotes, references, table of contents, and bibliographies) can be generated easily. Professional output: look as if printed. 15 / 48 Miguel Vidal LA in a Nutshell

16 Caveats LA Installing LA Not WYSIWIG. Hard learning curve. Absolute space/positioning is tricky (it s very hard to write disorganized documents). Design of a whole new layout is difficult and takes a lot of time. Need to be compiled. 16 / 48 Miguel Vidal LA in a Nutshell

29 Installing L A LA Installing LA For using L A you need: A text editor for editing your L A source files. A L A distribution for processing (compiling) your L A source files into PDF or DVI documents. A PDF/DVI viewer for previewing and printing documents. 22 / 48 Miguel Vidal LA in a Nutshell

33 DVI Output LA Installing LA Device independent file format (.dvi) Binary data independent on any specific image format, display hardware or printer. A L A distribution for processing (compiling) your L A source files into PDF or DVI documents. DVI is not a document encryption format. Not support embedded fonts (fonts must be already installed). 26 / 48 Miguel Vidal LA in a Nutshell
