Hi,

I am trying to achieve the following:

\setMPtext{1}{ABC} \setMPtext{2}{DEF} \setMPtext{3}{GHI}

\starttext

\startMPpage[offset=1ex,width=\paperwidth,height=\paperheight] for i=1 upto 3: draw textext(\MPstring{i}) shifted(i*cm,i*cm) ; endfor; \stopMPpage

\stoptext

There is no error but no content either. What's wrong?

Another way to do this is to use

\TeXtext{1}{ABC} etc.

and then call

draw sometxt(i)

For Sec 4.5 of Mojca's my way on sometxt http://dl.contextgarden.net/myway/sometxt.pdf

Thank you for the tip, I tried it, but sometext seems deprecated in mkiv ("[do we need TeXtexts in MkIV]").

I thought that you were using MKII.

I've different buffers named 1–12 and would like to pipe them to Metapost. I thought I could use a textext(\getbuffer[i])-construct, it failed. So I tried it with \setMPtext{}{} …

What is the approach to achieve this?

Well, if nothing else works, you can always cheat. \startluacode userdata = userdata or {} userdata.labels = { [1] = "ABC" , [2] = "DEF" , [3] = "GHI" } function userdata.shift(i) return "(" .. i .. "cm ," .. i .. "cm )" end function userdata.draw(i) return "draw btex " .. userdata.labels[i] .. " etex shifted ".. userdata.shift(i) .. ";" end \stopluacode \starttext \startluacode context.startMPpage({offset = "1ex", width = [[\paperwidth]], height = [[\paperheight]]}) for i = 1,3 do context(userdata.draw(i)) end context.stopMPpage() \stopluacode \stoptext Aditya

In the "real world“ I've stripped quotes form another document and stored them in buffer-environments (attachment).

Save them as lua tables. Much easier to manipulate than tex objects.

With your solution I've no idea how to incorporate them in a "automatic" manner.

You just need to work a little harder. \startbuffer[1] This is a test \stopbuffer \startbuffer[2] Another test \stopbuffer \startbuffer[3] And again \stopbuffer \startluacode userdata = userdata or {} function userdata.shift(i) return "(" .. i .. "cm ," .. i .. "cm )" end function userdata.buffers(i) local idx = string.format("%s",i) local b = buffers.data[idx] if b then if type(b) == "table" then return table.concat(b) else return b end else return "unknown" end end function userdata.draw_buffer(i) return "draw btex " .. userdata.buffers(i) .. " etex shifted ".. userdata.shift(i) .. ";" end \stopluacode \starttext \startluacode context.startMPpage({offset = "1ex", width = [[\paperwidth]], height = [[\paperheight]]}) for i = 1,3 do context(userdata.draw_buffer(i)) end context.stopMPpage() \stopluacode \stoptext Aditya

I'm sure that there's a workaround (or at least a dozen of other ways), but I have no time (and my computer is being repaired again) to inspect right now.

Some tips?

MKIV is both very powerful and fast, so you could probably also define strings inside metapost run, something like

string mystrings[]; strings[1] := "ABC"; strings[2] = "DEF"; draw textext(strings[1]);

Untested.

It works, but if you loop it the problem remains. Thanks! Andreas
