ConTeXt and the blind
by Alan Bowen 15 Apr '04

15 Apr '04

I have very recently launched a new journal which has been designed on the assumption that it will exist in both electronic form and in print—hence, it is produced using ConTeXt and exists natively in PDF files. This morning I was asked by a colleague who is totally blind whether it would be possible to for him have ASCII or .txt files that he could use easily with his screen reading software. (My sense is that he may be able to use PDF files with this software, but that it is not easy.) So, does anyone on the list have ideas about how to produce such files from the files I currently have in hand or any experience with this sort of problem? Is there, for instance, a way to strip away all the formatting commands from a ConTeXt source file automatically so as to leave an unencoded .txt file that I could send him? I gather that he can use .htm files, but so far as I can tell there is no path from a ConTeXt source file to an HTML file—at least, a specific query about this made recently on this list by someone else seems to have gone unanswered. Cheers, Alan

vim syntax file for ConTeXt
by Gour 15 Apr '04

15 Apr '04

By lookin' at mailing lists' archive I saw several posts regarding Scite as editor of choice for ConTeXt. Since I'm using vim, I'd like to stay with it, so does someone have some vim syntax file tailored for ConTeXt? Any ConTeXt vim user?

Generalized \installcompoundcharacter
by Matija Pretnar 15 Apr '04

15 Apr '04

With the advent of UTF-8, there comes a great possibility to improve readability of the TeX code. For example: instead of \int_a^b, you could write S_a^b, where S is the character for integral. Or greek letters and any other math symbol imaginable. I tried using \installcompoundcharacter S {\int} and similar commands and all the characters show up nicely, but the spacing is all wrong, because they are interpreted as variables instead of operations, relations, ... I think this replacement would be easy to implement (if it isn't already implemented), because with math symbols, you don't have to worry about hyphenation. You could simply replace the characters with corresponding command before sending it to TeX. I already made some kind of python script that does that, but for each file separately. And with many files, you have to preprocess each one individually, which sums up to another shell script and many temporary files. Cheers, Matija

Re: help required w.r.t " vardef "
by vinuth madinur 15 Apr '04

15 Apr '04

I'm sorry that I hadn't read the mail by Jonathan Nicholl. Yeah, that was very clear and precise . thank u all. But I still can't figure out how I can have the contents of variables or the expansion of "def" as suffixes.I now think it's not possible with "def". I'll try out somethings now. Thanks again.

Re: help required w.r.t " vardef "
by vinuth madinur 15 Apr '04

15 Apr '04

Thanks Hans! That wolud help me a lot.Also thanks for the reference u mentioned.I'll try it. Now one last thing : Is there a way of having variable arrays whose contents can be used as "suffixes"? something like , a[0]:= "A" ; a[1]:= "B" ; a[2]:= "C" ; %a variable array "a[]" there are other three "pair" variables : T.A,T.B,T.C; so now I want to have , i := 0; T.a[i] = blahblah(); so here I want to use the contents of "a[]" as suffix of variable " T " . I don't know what kind of data type to use for "a[]". I tried a[] as string type and used it with forsuffixes $=a[0],a[1],a[2]: ..... endfor; but this does not work. So, can u please help me out here? thanx in advance.

Moving chapternumber in the margin ...
by Willi Egger 13 Apr '04

13 Apr '04

Hi everybody, Studying the details manual I thought to have found a way to print the chapter number on the margin. Each increase of the chapternumber would move the figure a predefined distance downwards. Now when using a \def{\dimexpr(\realpageno\rightmarginwidth)} my chapternumber moves down. Replacing the \realpageno with \currentheadnumber the chapternumber is not moving or only after a couple of pages ... Is there someone who could hint me how to approach this? Please refer to the attached sample file "bleedingchapternumber.tex" Thanks and regards Willi % pagenumbers in the margin at half makeupheight % % Context file % filename: bleedingchapternumber.tex % W.

Two lines in header
by John Culleton 13 Apr '04

13 Apr '04

A current book has a title that is too long to fit in the textwidth when set with expanded spacing. I want to set up the even page header like this: 101 Home Based Businesses for Pet Lovers \break doesn't work. Two backslashes don't work. Suggestions? -- John Culleton Able Typesetters and Indexers http://wexfordpress.com
