TeX was designed with two main goals in mind: to allow anybody to produce high-quality books using minimal effort, and to provide a system that would give exactly the same results on all computers, at any point in time. This method, dating back to the 19th century, produced a “good classic style” appreciated by Knuth. 30 March 1977, he found them awful. Macbook auto open download pdf that time, Knuth saw for the first time the output of a high-quality digital typesetting system, and became interested in digital typography.

The disappointing galley proofs gave him the final motivation to solve the problem at hand once and for all by designing his own typesetting system. On 13 May 1977, he wrote a memo to himself describing the basic features of TeX. 1989, more than ten years later. 1978, when Knuth was developing his first version of TeX.

TeX from the same original file. A new version of TeX, rewritten from scratch and called TeX82, was published in 1982. 256 different characters in the text input. This is a reflection of the fact that TeX is now very stable, and only minor updates are anticipated.

The current version of TeX is 3. The design was frozen after version 3. Even though Donald Knuth himself has suggested a few areas in which TeX could have been improved, he indicated that he firmly believes that having an unchanged system that will produce the same output now and in the future is more important than introducing new features. Likewise, versions of METAFONT after 2. 1991, primarily to enhance TeX’s multilingual typesetting abilities.

Almost all of TeX’s syntactic properties can be changed on the fly, which makes TeX input hard to parse by anything but TeX itself. Expansion itself is practically free from side effects. In this sense, this stage is like lexical analysis, although it does not form numbers from digits. Here characters get assembled into a paragraph. TeX’s paragraph breaking algorithm works by optimizing breakpoints over the whole paragraph. The fourth stage breaks the vertical list of lines and other material into pages. The TeX system has precise knowledge of the sizes of all characters and symbols, and using this information, it computes the optimal arrangement of letters per line and lines per page.

This dvi file can be printed directly given an appropriate printer driver, or it can be converted to other formats. Knuth’s original default format, which adds about 600 commands, is Plain TeX. By default, everything that follows a percent sign on a line is a comment, ignored by TeX. TeX provides a different text syntax specifically for mathematical formulas. The formula is printed in a way a person would write by hand, or typeset the equation. TeX syntax, and closing again with another of the same symbol. Knuth explained in jest that he chose the dollar sign to indicate the beginning and end of mathematical mode in plain TeX because typesetting mathematics was traditionally supposed to be expensive.

The TeX software incorporates several aspects that were not available, or were of lower quality, in other typesetting programs at the time when TeX was released. Some of the innovations are based on interesting algorithms, and have led to several theses for Knuth’s students. While some of these discoveries have now been incorporated into other typesetting programs, others, such as the rules for mathematical spacing, are still unique. Knuth looked closely at these printed papers to sort out and look for a set of rules for spacing. While TeX provides some basic rules and the tools needed to specify proper spacing, the exact parameters depend on the font used to typeset the formula. Knuth for the first time, new spacing parameters had to be defined. The typesetting of Math in TeX is not without criticism, particularly with respect to technical details of the font metrics, which were designed in an era when significant attention was paid to storage requirements.
