metafun- how to pass array as an argument
by dalyoung 24 Jan '11

24 Jan '11

Dear all, I draw a simple figure using the code as below. In the code, I use "for i = 3,5,0,2,1,7:" in def draw_balls. However, if I can pass the array "3,5,0,2,1,7" as an argument for def draw_balls (expr n) and call draw_balls (3,5,0,2,1,7), then it can be used for different number of balls and number of boxes. Is there a way to do that or any suggestions? Thank you for reading. Regards, Dalyoung \startbuffer[a] path p; numeric bwidth, u, lastpoint; u :=1cm; p := fullcircle scaled .3u; lastpoint := 0; def draw_balls = %(expr s) draw (0,0) -- (0, u); for i=3,5,0,2,1,7: for j = 1 upto i: draw p shifted (lastpoint+.32*j*u,.3u); endfor; bwidth := .32i*u+.5u; draw (lastpoint,0) -- (lastpoint +bwidth,0) -- (lastpoint +bwidth,u); lastpoint := lastpoint+bwidth; endfor; enddef; draw_balls; \stopbuffer \starttext \processMPbuffer[a] \stoptext

Layer(s)
by Ian Lawrence 24 Jan '11

24 Jan '11

Morning, I am completely defeated by layers...from a more or less complete beginner.. So please be gentle. I think you ought to be able to have multiple layers and so to switch them on and off, using modes. However I can only find examples and documentation for single layers in use at any one time. If this is true then I can also see that there ought to a parameter that sets the stacking order of the layer... So I think I need to know about \setuplayer (just guessing) But: http://wiki.contextgarden.net/Command_Syntax/Missing#layer_commands So if any one of you kind people can help with the missing syntax, or a **simple example** of a multiple layered document, I'd be grateful. Thanks Ian

Vertical rules in multiple column mode
by Procházka Lukáš Ing. - Pontex s. r. o. 24 Jan '11

24 Jan '11

Hello, the following code generates 3column pages: --- \starttext \startcolumns[n=3,rule=on] \dorecurse{5}{\section{\recurselevel}\input knuth} \stopcolumns \stoptext --- You can see that the vertical bars on the page 1 don't reach the "real" bottom of the "text height", whilst they do on the next page. It seems that the length (or "range") of the vertical bar is given by the height of the FIRST column. It seems to me that the rule height should rather be given as (or related to): 1) MAXIMUM of height of all columns 2) or height of i-th rule as maximum of height of i- and (i+1)-th column (each two ADJACENT columns). Is there a way how to effect this? Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

Downloading long urls
by Aditya Mahajan 23 Jan '11

23 Jan '11

Hi, While downloading urls, context santizes the filename but does not check the length of the url. So, one can end up with a situation where the filename is too long for the operating system to handle. For example, the following fails on 32bit linux. \enabletrackers[resolvers.schemes] \startluacode local report_webfilter = logs.new("thirddata.webfilter") local url = "http://www.bing.com/search?q=Areallyreallylongstringjusttoseehowthingsworko…" local specification = resolvers.splitmethod(url) local file = resolvers.finders['http'](specification) or "" if file and file ~= "" then report_webfilter("saving file %s", file) else report_webfilter("download failed") end \stopluacode \normalend Is there a robust way to avoid this problem? One possibility is that in data-sch.lua instead of local cleanname = gsub(original,"[^%a%d%.]+","-") use local cleanname = md5sum(original) What do you think? Aditya

Forming paragraphs
by Procházka Lukáš 23 Jan '11

23 Jan '11

Hello, I would need to form paragraphs to such a shape: Abc defhi jklm nop qrst uvw xyz. ABCDE FGHIJKL MNOPQR STUW XYZ. Abc defhi jklm nop qrst uvw xyz. ABCDE FGHIJKL MNOPQR STUW XYZ. Abc defhi jklm nop qrst uvw xyz. ABCDE FGHIJKL MNOPQR STUW XYZ. <-- \textwidth ---------->| I.e. paragraphs whose first lines are always \textwidth in width and whose next lines are always somehow indented. I achieved the desired shape by the following combination of \setupnarrower and \setupindenting: --- \starttext \setupnarrower[left=2em] \startnarrower[1*left,0*right] \setupindenting[yes,-2em] \input knuth \stopnarrower \stoptext --- But I would like to ask whether this way is "clean" enough and/or there is a better way, especially via a kind of \setup<something> command, e.g. something like: \setupparagraph[MySpecialParagraph][first=0pt,next=2em] ... \startparagraph[MySpecialParagraph] Abc defhi jklm nop qrst uvw xyz. ABCDE FGHIJKL MNOPQR STUW XYZ. \stopparagraph % or: \startMySpecialParagraph Abc defhi jklm nop qrst uvw xyz. ABCDE FGHIJKL MNOPQR STUW XYZ. \stopMySpecialParagraph Kind regards, Lukas
