float combinations
by Robert Blackstone 14 Apr '13

14 Apr '13

Dear all, A few days ago (10 April 2013, Vol.106, Issue 25) I posted a question about giving related but not necessarily adjacent floats the same number, as for example Fig. 2a and Fig. 2b. In the meantime I found a, not very elegant, solution that only partly satisfies me. Here is a working example: (I trust the cow and the mill can be found). %--------------------------------------------------- \useexternalfigure[SmallCow][cow.pdf][height=2cm] \useexternalfigure[MediumCow][cow.pdf][height=3cm] \useexternalfigure[Mill][mill.png][height=3cm] \definelist[figure] \setuplist[figure][prefix=yes,label=yes,alternative=c] \starttext This file is for testing the possibility of giving two related musical examples (in old and modern notation respectively) the same figure number with a. and b. as suffixes to the number proper. \placefigure[here][SmallCow1]{A small cow.} {\externalfigure[SmallCow]} A cow again, in two sizes. \in{Figure}[SmallCow2]a shows the same cow as \in{Figure}[SmallCow1]. \placefigure[here][SmallCow2]{{\bf a}. Another small cow.} {\externalfigure[SmallCow]} And here a larger cow (\in{Figure}[MediumCow1]b). \setnumber[figure][1] \placefigure[here][MediumCow1]{{\bf b}. A larger cow.} {\externalfigure[MediumCow]} And here comes a mill. \placefigure[here][Mill1]{A mill.} {\externalfigure[Mill]} \page {\bf List of Figures} \placelist[figure] \completecontent \stoptext %---------------------------------------------------- This way "a" and "b" become part of the caption text, resulting in: Figure 2 a A small ….. etc., and: Figure 2 b A larger …etc. Likewise in the List of Figures. This is not what I would like. Is there a possibility, when not using Combinations, to get: Figure 2a A small ….. etc? Wherever possible I use Combinations but in some cases examples to be combined are very different in size and shape and/or too large to fit on one page together, so that one of them gets cut off. Is there a possibility, when using a combination of figures, to split it, in other words, to separate the figures spatially, to allow them to appear on consecutive pages, and maybe even allowing some text in between? Thanks in advance. Best regards, Robert Blackstone

Read output of external command
by Marco Patzer 14 Apr '13

14 Apr '13

Hi, I need to read the standard output of an external command. This is what I came up with: \starttext \startluacode f = io.popen "ls" context(f:read "*a") \stopluacode \stoptext It works with luajittex, plain lua5.1 and lua5.2, but it fails with a current luatex: ! LuaTeX error [string "\directlua "]:3: attempt to index global 'f' (a nil value) stack traceback: [string "\directlua "]:3: in main chunk. Why does this fail in luatex but works in lua5.2 ? What is the correct way to obtain the output of a command? Marco

As I wrote, wherever possible I use combinations for related examples, and they only give problems when the examples are too large to fit on the same page. The solution with itemize does not help here. With small enough figures the results seems not too different from that with Combinations. With large figures stacked vertically the lower one still gets cut off (and with it also the caption when it is placed underneath the figure). If somehow a pagebreak could be inserted between the two items, then this solution would probably work. But I have no idea how to achieve this. Inserting \page between " \startitem A cow\stopitem" and "\startitem A mill \stopitem" changes nothing. Best regards Robert

Hi Alan, Thank you for your reaction and your suggestions. Indeed, it is not exactly what I envisaged. I would be happiest if there were a way to add a and b as a suffix to the number, like Figure 2a. With combinations it is easy to have a general Caption and specific captions for the components of the combination. But for the List of Figures I see no other possibility than, for instance "2 Dutch scenery. a. Cow, b. Mill". In fact I have no problems when I can make use of a combination, but, as I wrote, sometimes combinations are impossible for lack of space on the page. What you describe as a challenge for Hans could be perfect, I think, provided an itemization can be interrupted and continued on next page. (I tried your liitle code snippet but ConText would not have it.) Splitting a float combination might turn out to be simpler. Only I have no clue as to how to achieve that. Thanks again. Best regards, Robert

[***SPAM***] \setscript blocking \hskip functionality
by hwitloc＠gmail.com 13 Apr '13

13 Apr '13

I found that using \setscript{nihongo} breaks the functioning of \hskip. Here is a minimal example. MKIV required. Text source is UTF-8 encoded text. In the first case without \setscript the Japanese \hskip properly functions, but just after the \setscript macro it fails (without err or mention). However, it is interesting to note that \hfill does work in both cases with standard alphabet text. %-------------------------------- \usemodule[simplefonts] \setmainfont[ipaexm] % using a font having Japanese characters \starttext \underbars{Without setscript:} Alphabet\hskip 2cm text 漢字\hskip 2cm 文書 \setscript[nihongo] \underbars{With setscript:} Alphabet\hskip 2cm text 漢字\hskip 2cm 文書 \stoptext %-------------------------------- end

Re: [NTG-context] Too many word-breaks in consecutive lines
by "H. Özoguz" 13 Apr '13

> 100 % automated typesetting > with 100 % perfect results is impossible Hans, I dont think so. Manual typesetting is not "100 % perfect", too. Why automated typesetting shouldn't be able to obtain the same results, like men – some day. Of course that needs much more than just typesetting-rules, e.g. some times one has to rephrase some sentences to get a good result, but this will be possible for programms in future, too. For typesetting alorithms it holds the same, like for chess programms in the past, now fulfilled: They will get to the men-level, and even (far) beyond that. Huseyin

Different fonts for titles
by "H. Özoguz" 13 Apr '13

13 Apr '13

Hi there, how can I use a different font for titles using simplefont? (chapter, section, subsection, ....) At now, I use (e.g.) \definedfont[name:fontname at 12pt], but for many fonts, that results in bad kerning (empty space between characters), but for some fonts, that works. So, is there a better way to change easily the font (using Simplefont maybe), and how to set the title-fonts (no typescript, if possible :)) Thanks! Huseyin

Too many word-breaks in consecutive lines
by "H. Özoguz" 12 Apr '13

12 Apr '13

Hi (sorry for many questions today :)), with German you often have the problem, that words are long (most often much longer than english words). So ConTeXt have to break them. But there is a typographical rule: "Do not break words at the end of lines in more than three consecutive lines." So four (or more) breaks each ofter another (line), is forbidden and considered as ugly! By default, ConTeXt does this in many cases, specially with DIN A5 and long words. And I have to manually fix this in every case, that is normal and ok. Is there a way to highlight these attempts of more than three consecutive breaks in one paragraph? Would be easier to find, and to not-oversee. Future suggestion: Perfectly ConTeXt would try to avoid those breaks, but I suspect that would end in ungly kerning and unnormal gaps between words, correct? Huseyin
