2. On the other hand if the majority of the TEX community spends time and energy on BIFX ConTEXt LuaTpx in general on successors of TEX it is hard to stay with plain TEX to stay with Knuth which means without development However if one thinks a little deeper it is an ill posed rhetorical suggestion TEX is a fixed point only the environment changes Adaptation to PS is for example taken care of by the driver dvi 2 ps and ilks and pdf output can be obtained by Distiller or Acrobat not tested though by me for a document or just one of the various pstopdfs TEX commands for handling colors and inclusion of graphics are dictated by the drivers and have to be included in specials I have no problems at all to leave MetaFont for MetaPost because well again an ill posed suggestion I don t leave MetaFont I just don t use it for graphics any longer l m not a font designer Well again partially true I ll continue to use MetaFont as my poor man s limited MetaPost previewer Kees van der Laan MetaFont and MetaPost have different purposes the first one is aimed at bitmap font design the second at creating PS graphics for inclusion in AnyTgX or troff The MetaFontbook is still needed because of the unusual concepts suffix vardef primarydef secondarydef and tertiarydef which MetaPost has taken over from MetaFont and which I don t grasp completely yet A middle road is provided by ConTpXt which also comes wi

He continues that he would like to use TEX and provided macros well his pre processor TEX has a more powerful gen eral mechanism for placing images in a paragraph But HTML Word are simpler to use Be aware Sveta uses Photoshop interactively for a o coloring MetaPost and ilks allow for coloring in a workflow I don t know how to achieve by MetaPost the effects Sveta can do in Photoshop Libraries for macros and pictures are necessary for reusing parts AnyTEX is a preprocessor of TEX TEX itself has a built in preprocessor called macro expander MetaPost is a preprocessor of PostScript and even can produce SVG with the MetaFont ingenuities inherited So at the basis is plain TEX and PS A nicety in the table chapter of PWT next to the wealth of examples similar to those given in the TEXbook and some more is a little spreadsheet function ality which can be used in budget table markup to en hance data integrity It automates addition or subtraction of table entries which is not that trivial because TEX does not come with the ordinary calculator functionalities rano bz MACROS IN PLAIN eZ a PICT IN PS This is similar to my plea of long ago in the IFIPWG2 5 write portable numerical library algorithms in the lowest higher level language FORTRAN for use in all other higher level languages Moreover those FORTRAN algorithms could be highly optimized for example the m
4. TEX From now on if I refer to TEX in the perspective of LuaTEX I mean Good Old TEX the language as well as the functionality Although LuaTgX provides a couple of extensions it remains pretty close to compatible to its ancestor certainly from the perspective of the end user As most Con TgXt users code their documents in the TeX language this will remain the focus of mxiv After all there is no real reason to abandon it However although ConTEXt already stimulates users to use struc ture where possible and not to use low level TEX com mands in the document source we will add a few more structural variants For instance we already introduced startchapter and startitem in addition to chapter and item We even go further by using key value pairs for defining section titles bookmarks running headers ref erences bookmarks and list entries at the start of a chapter And as we carry around much more informa tion in the for TEX so typical auxiliary data files we provide extensive control over rendering the numbers of these elements when they are recalled like in tables of contents So if you really want to use different texts for all references to a chapter header it can be done startchapter label emcsquare title About e mc 2 bookmark einstein list About e mc 2 Einstein reference e mc 2 content Nstopchapter Under the hood the mx v code base is becoming quite a mix and on
5. jargon Mathematics from the language point of view is a jargon with its own symbols structures meanings and definitions In typesetting Math TFX is superb still unmatched But Microsoft with its Cambria project and the use of OpenType Math fonts may have taken the lead Other jargons can be typeset equally well but you have to write the equivalent of the intelligent math mode yourself I have not heard of such an effort Jargon books are more complicated than novels es pecially with respect to tradition in typesetting the jargon such as contents back matter an index tables of contents pictures tables references and cross links For typesetting Math one must be a mathematician have enjoyed a Math education in short one must know the jargon But That is not enough at least with the mathematical training I enjoyed No typesetting conventions of math was ever taught to me No Mathematical writing 1989 by Knuth as main author who else existed Happily TEX embodies it all the subtle spacing around Math symbols the awareness of operators and how to typeset them in context the composition of symbols with limits for example is all taken care of by TEX though TEX is not perfect In line Math and displayed Math may look different The choices made by TEX implemented in the Math mode are wired in but parameterized Math constructs can be marked up by using macros The Math fonts are not just o

13. When using a font family which provides optical design sizes a typical setup will use font sizes of 10 pt 7 pt 5 pt for the text font and the first and second level indices In this case the 7 pt indices are usually small enough so that a build up of superscripts and subscripts does not exceed the body size When using a font without optical design sizes the second level indices may become unreadable if a scaled down version of the base font is used at 5 pt so a different progression of sizes is used such as 10 pt 7 5 pt 6 pt In this case the 7 5 pt indices may turn out a little too big so that a build up of superscripts and subscripts may require the next larger sizes of roots or delimiters Spacing and backspacing By default TEX does a good job of spacing in math mode based on the various classes of math symbols such as ordinary symbols binary operators relations openings closings or punctuation However in some cases it may be desirable or even required to insert space manually for better results The most common example of manual spacing occurs in integrals where a thinspace is usually inserted before each differential term such as in res ev 5e rarsinsatae There is no need for a thinspace after an index or exponent such as in r2dr where a visual gap may not be needed or before an operator such as before sin where space is inserted automatically However there is a need for a thinspace before d

24. Besides that the Lua side also has special treatment for encapsulated Python functions and methods The most obvious way to implement calling of Python objects inside the Lua interpreter is to implement a call function in the bridging object metatable Unfortunately this mechanism is not supported in certain situations since some places test if the object type is a function which is not the case of the bridging object To over whelm these problems Python functions and methods are automatically converted to native Lua function closures becoming accessible in every Lua context Callable object instances which are not functions nor methods on the other hand will still use the metatable mechanism Luckily they may also be converted in a native function closure using the asfunc function if necessary e According to 68 page 47 a closure is a function plus all it needs to access non local variables correctly a non local variable is neither a global variable nor a local variable For example consider newCounter function newCounter local i 0 return function i i l return i end end c1 newCounter print c1 gt 1 print c1 gt 2 c2 newCounter print c2 gt 1 print c1 gt 3 print c2 gt 2 i is a non local variable we see that there is no interference between c1 and c2 they are two different closures over the same function E35 E36 MAPS 39 It s better to track a

43. 5 22 Our starting point is that this modus operandi has too many drawbacks especially for non English speaking future users in particular for French speaking ones First only a few students are familiar with typing texts quickly and intensively even if some have already used comput ers They may make some typing mistakes in command names Of course any BIFX teacher is able to fix them but the price to pay is loss of time and dynamic Besides students need to be convinced of BIEX from their first experiments They should see that this word processor is suitable for large sized texts at the beginning they should be able to observe that it is easy with TEX to ap ply some changes related to layout changing characters basic size switching one column and two column lay outs All these goals can be reached only if students are given a text already typed and ready to be processed That is compiling this text should be successful the first time so there is no anxiety about this point Besides let us not forget that the most natural choice for a text to be typed by French students is a text in French But some typographical rules are different from English ones for example a thin space produced by the TEX command is to be put just before a high punctuation sign such as an exclamation or question mark Joie bonheur et d lectation whereas the same signs are glued to the preceding text in English E
