Some are subjective. + \StopItem + \StartItem + You like the way it works: you edit a document using a simple editor, + add a couple of directives and delay rendering. It's the content and + structure that matter. + \StopItem + \StartItem + You need it for instance because you have to typeset math and you believe that + no other tool can do a better job on that. + \StopItem + \StartItem + You found out that it can save time because it is programmable and after all, + programming is a nice distraction from writing. + \StopItem + \StartItem + You don't want to change a 20 year old habit and why quit using something that + you know well by now. + \StopItem + \StartItem + You like an occasional fight with a batch oriented system and updating (sometimes to + the extend of compiling) can be done while watching a movie. + \StopItem + \StartItem + You dislike learning a new program every 5 years. Of course it would be different + if we'd live for 500 years. + \StopItem +\StopItems + +\StartItems{My reasons to use \TEX} + \StartItem + I've always used \TEX\ and can do what I need to do with it. I like to + focus on what can be done instead of what can't. + \StopItem + \StartItem + I don't like disposable tools and am quite lucky that \TEX\ still + can adapt to my needs. + \StopItem + \StartItem + I like my job but only when using the current tools and cooking up + reuseable solutions. + \StopItem + \StartItem + I need it for rendering (often educational) content and also use it + for fun. + \StopItem + \StartItem + In the process I need to implement styles based on designs provided by + designers, most probably only know click and point tools but some of them + can think outside that box. + \StopItem +\StopItems + + +\StartItems{Using \TEX\ in projects} + \StartItem + Each project has at least a few challenges, the input, + the design, graphics, the boundary conditions, interfaces, etc. + \StopItem + \StartItem + In quite some cases a printed product is an afterthought and coding is + driven by viewing on the web. + \StopItem + \StartItem + Most time goes into mapping structure. Coding is done in \XML\ because + we can then manipulate content and publishers can reuse it. + \StopItem + \StartItem + Publishers often use a preselected designer and ask him/her to come + up with a design. + \StopItem + \StartItem + Chapter openings and title pages take some effort as well, especially + if the implementation has to be exact. For some reason design comes before + content so the designer has to guess. + \StopItem + \StartItem + Although one can try to catch bordercases it hardly pays off as the eventual + solutions are not that logic. Simplification is preferred over heuristics. + \StopItem + \StartItem + Unfortunately designers never use the fact that we can program variations and + and flexible solutions. On the other hand in a later stage we can quite conveniently + provide solutions for problems resulting in the editorial workflow. + \StopItem +\StopItems + +\StartItems{Struggling with structure} + \StartItem + Structure in regular \TEX\ documents assumes a proper nesting of chapters, + sections, subsections etc. + \StopItem + \StartItem + In \CONTEXT\ we can clone heads and configure them independently. Often we end up with + tens of variants. + \StopItem + \StartItem + In practice numberings can intermix, for instance subsections can be numbered + per chapter instead of per subsection. + \StopItem + \StartItem + Numbers seldom run like 1 \unknown\ 1.1 \unknown\ 1.1.1 and individual components can be omitted and can + have different properties (font, color). This quickly becomes messy as more (unexpected) + structure is added. + \StopItem + \StartItem + It's for this reason that we now have a more complex model of resetting and synchronization + of states in \CONTEXT. Actually we keep adding more structure support. + \StopItem + \StartItem + Additional information that is used in a chapter sometimes is also used elsewhere, as + in tables of contents (for instance icons). Therefore in \CONTEXT\ \MKIV\ we now have + the possibility to let userdata travel around. + \StopItem +\StopItems + +\StartItems{Bringing system in color} + \StartItem + When making a product line it helps if there is some systematic + approach in defining colors but it does not work out that way. + \StopItem + \StartItem + Unfortunately we can never use the colorpalet and colorgroup features + that have been present in \CONTEXT\ from the start. + \StopItem + \StartItem + Spotcolors are nice as they enforce a more systematic approach than + process colors. In such cases there is often some system. + \StopItem + \StartItem + With processcolors we often have to fight the \quotation {on my screen 0.01 + \letterpercent\ makes a big difference} dilemma. + \StopItem + \StartItem + Automatically converting graphics to such color spaces can save a lot of time and + money. + \StopItem +\StopItems + +\StartItems{Relations between fonts} + \StartItem + Although there is some fashion in using fonts most designs use at least + a few different ones. + \StopItem + \StartItem + Not all fonts are equally well equipped and one cannot rely too much on + features without testing them first. Although \OPENTYPE\ makes things + easier it also introduces problems due to incomplete features. + \StopItem + \StartItem + A macro package assumes some logic in sizes and relations but this is of no + use in practice. Most if the font mechanism is simply not used. + \StopItem + \StartItem + The same is true for interline spacing. Often some standard latin quote and + title is used to determine the spec. Not seldom most spacing is inconsistent. + \StopItem + \StartItem + It looks like justification is not wanted that much, let alone advanced features + like protrusion and expansion. Inter|-|character spacing is sometimes requested. + \StopItem +\StopItems + +\StartItems{Why I still use \TEX} + \StartItem + We started making \CONTEXT\ for our own use, especially complex and demanding + educational documents. + \StopItem + \StartItem + Nowadays we stick to typesetting and as we specialize in automated processing + we have to operate within strict bounds. + \StopItem + \StartItem + We use not that many handy features as there is hardly any structure in the designs + we have to implement. + \StopItem + \StartItem + But we use quite some of the manipulative power of \CONTEXT. Also, we are able to + fulfil even the most extreme demands. + \StopItem + \StartItem + It's user demand that is the driving force behind most new features. Users typically + use \CONTEXT\ in a different way than we do. + \StopItem + \StartItem + And \unknown\ some things can probably only be done with \TEX, especially in automated + workflows. + \StopItem +\StopItems + +\StartItems{Suggestions for designers} + \StartItem + Talk to those implementing the design, let them show you what can be done. Stick to + general designs and don't go into much detail. It's the look and feel that matters. + \StopItem + \StartItem + Think in systematic solutions. Lack of freedom in interactive placement of graphics can + be compensated by other variations. + \StopItem + \StartItem + Think outside the box. Use the fact that the system is programmable and can adapt. And it + probably goes beyond what you can think of. + \StopItem + \StartItem + Try to make a design extensible. There will always be more structure. Some components + will have less text that expected. Titles can be very short or quite long. Keep in mind + that you cannot tweak. + \StopItem + \StartItem + Try to see a pattern in structure and provide escapes for strange cases.
