Hi all, I think for the sake of my sanity I am going to stop building prototypes now. I am very grateful to those who have been very helpful along the way, answering what must have seemed like foolish questions. I'd have to say that getting to grips with Context has taken longer than I bargained for, and has not been as smooth as I hoped. But without you, collectively, extreme frustration would have kicked in long ago. I am based in the UK and have a moderate budget to develop some frameworks in which to publish a series of documents that'll be up for being maintained. This will be the third iteration for some of the collection, which have appeared on CD-ROM in a Macromedia shell, then as rich pdfs with an InDesign - Acrobat Pro workflow. Now, maybe, they'll find a final home in Context, at least for the pdf versions. There are two pieces of work, I think, requiring different skill sets, I think. 1) To build some context templates, using modes and layers to give me the ability to produce pdfs of varying 'heft' by switching in and out layers. What people might read on a smartphone / iPad ought to be different to what they might get on a fast desktop / laptop running Acrobat, so permitting embedded swfs. The text is already highly structured and the trick will be to implement a document that automates much of what must be done by hand in InDesign, and to fully exploit the facilities in Context. 2) (This might be some heavy lifting, so may be best thought of separately). To build the wherewithal to allow rich swfs to be placed in the resulting pdfs by Context, at their natural size and at a specified location, and loading in poster frames and directories of assets where these exist (for which you currently have to use Acrobat Pro). It is possible that I could, eventually manage the first, but I'd expect someone with a history of working on Context to do a much more elegant, clean and maintainable job. The second task is will need some cunning coding in Lua, or equivalent, I expect. Anyone interested, please contact me off list, where we can discuss further details. I am at: Ian.Lawrence at Physics.org Two notes: Since the work is on behalf of the right kind of organisation, I'd anticipate putting the results of (2) back into the community - that's what we're doing with our other 'engine' (Flash) development. It'll be easiest for my finance department if you are a consultant or business that can raise invoices. kind regards Ian

compare locations of two pagereferences
by Daniel Schopper 02 Mar '11

02 Mar '11

Dear all, how can one compare the locations of two pagereferences for conditional processing? I tried it with this (mkiv, 2011.01.10): \starttext \pagereference[page:a]bla \pagereference[page:b]bla \at[page:a] % 1 \at[page:b] % also 1 \doifsamestringelse{\at[page:a]}{\at[page:b]}{same page}{different page} % yet, the else-branch gets executed \stoptext Of course this is clumsy, but although I tried to peek into strc-ref I couldn't quite sort out how to directly access the results of \at. Thanks Daniel

Letter with letterhead
by Roger Mason 02 Mar '11

02 Mar '11

Hello, I must write a multi-page letter with only the first page as (pre-printed) letterhead. I adapted the Letterhead example from the wiki to fit the style of my institution. I would like to know how to revert the second and subsequent pages to use a default layout. If someone know how to use Wolfgang's letter module (in MKII) with letterhead on the first page only, that would be fine. Thanks, Roger

Numbering again..
by Ian Lawrence 02 Mar '11

02 Mar '11

Sorry...Again I am stumped. I have a counter that I'd like to reset \newcounter \nuggetnumber \def \numberofnuggets{0} \definehead [nugget] [section] \setuphead [nugget] [number=yes,page=yes, before=\increment \nuggetnumber, after=\savecurrentvalue \numberofnuggets{\countervalue{nuggetnumber}},] % LO as nugget This counts the number of nuggets.. and seems to work fine. But when it gets to an episode it should reset....so, maybe like this \definehead [episode] [title] \setuphead [episode] [numberstyle=bold, textstyle=cap, number=yes,before=\resetnumber[nuggetnumber]] % may be used But \resetnumber[nuggetnumber], where-ever I put it seems to have no impact. I think the Wiki suggests that it should, and the mailing list back catalogue and the manual shed no light on the matter.... while I am at it, I am equally unsure how to reset the numberofnuggets accumulator, which should also be done on meeting the episode structural element - I'd like to insert a whole chain of commands in the before=...' Thanks Ian

ConTeXt licensing
by Joseph Wright 02 Mar '11

02 Mar '11

Hello all, A question came up recently on the tex.sx site about ConTeXt licensing: http://tex.stackexchange.com/questions/12431/using-context-commercially I have a feeling I've seen something similar elsewhere recently, but cannot be sure where. This question seems to require an 'official' response, as things do seem a little confusing (at least to me). I'm happy to post something as a reply to the question if I know what the position is (or indeed if it is "read what we've put and go with it".) -- Joseph Wright

A question about data types?
by Ian Lawrence 02 Mar '11

02 Mar '11

Sorry. me again...and I have been all over the wiki, mailing lists and manuals... I have this: \setlayer [progresssteps] % name of the layer [hoffset=904 px, voffset= 28\nuggetnumber px] % placement (from upper left corner of the layer) {\stepstack} % the actual contents of the layer And I am hoping that as I increase nuggetnumber the voffset of the layer will be 28*nuggetnumber I am setting nuggetnumber like this for the moment: \def \nuggetnumber{3} (in the other dev document it is the result of counter, so set dynamically) and this in the text \nuggetnumber which compiles to '3', so I assume the assignment is good to go. varying both nuggetnumber and the scale factor (28) shift the layer up and down, but not in a way that suggests that 28\nuggetnumber is being evaluated as a product (so a scale factor of 7 and a nuggetnumber of 2 do not give the same output as a scale factor of 2 and a nuggetnumber of 7). So I am led to think that there is something in the evaluating that is going wrong - data types / units? (if I hard code in the results I am expecting, say 28 px, 56 px or 84 px then I get exactly what I want... Thanks, as ever (Same result in ConTEXt ii or iv) Ian

breaking up long input into metapost pages
by Hans van der Meer 02 Mar '11

02 Mar '11

I now have a long input file with many independent sections. For the moment it is processed as follows: \starttext \startTEXpage \startMPcode % variable declarations % macro definitions with drawing code input input_data; \stopMPcode \stopTEXpage \stoptext Now this becomes a bit too large for one page, I tried a Metapost run in luatex but after taking some 12 GB of memory it gave up. The idea is thus to have one contiguous input which at certain points produces a new startTEXpage. That will flush the internal memory I guess and makes long documents possible. I'd rather not split the input_data in seperate files: making a thousand of more files seems no nice prospect to me. Any ideas how to best structure things? I should mention that I have a lot of control over the writing of the input_data. Hans van der Meer

Short words in word list
by Florian Wobbe 02 Mar '11

02 Mar '11

Hi, \usemodule[s-lan-03] \setupspellchecking[state=start,method=2] \setupspellchecking[list=words] \ctxlua{languages.words.tracers.showwords()} prints a word list of words with 4+ letters. Is there a way to also include 1-, 2-, and 3-letter words? Thanks, Florian

That is beside the point. The problem is not the drawing of letters, but the extraction of pixel data from a Transport Stream packets. The specification of the DVB-subtitles mentions two variants: (1) string of characters, (2) pixel colorvalues to be looked up in a 16-value CLUT. The stream I have at hand consists of pixel data in a 720x36 rectangle. Furthermore different broadcast stations use different lettertypes. Of course it would be nice if I could simply extract the letters, but for the moment this surpasses my abilities.

Re: [NTG-context] Metafun Label and externalfigure Problem
by Jeong Dalyoung 02 Mar '11

02 Mar '11

Dear Lutz, After replacing "blblogo.pdf" with a figure file in my system and tested it. Otherwise, it shows a gray rectangle. I got no error and the output is fine.( "Test" and the figure are well shown) I don't know "rev 4090" but here is the version of ConTeXt minimal in my system. ... This is LuaTeX, Version beta-0.65.0-2010121316 \write18 enabled. (testmp.tex ConTeXt ver: 2011.02.25 22:03 MKIV fmt: 2011.3.1 int: english/english ... Since I don't know deep inside ConTeXt, I can't tell you a solution. Sorry. Setup in your system may be different from mine. Cheers. Dalyoung
