Hi Alan,

wrapping the URL (or the footnote that contains it, it will crash inside
the footnote) with \startasciimode...\stopasciimode works too:

\setupinteraction[state=start]
\unexpanded\def\mypersonalurl#1{%
\bgroup\tt\goto{\hyphenatedurl{#1}}[url(#1)]\egroup}
\starttext

\startasciimode
\footnote{\mypersonalurl{http://a.b?hpw%20h#pw}}
\stopasciimode

\stoptext

Thomas, my apologies, because I have just remembered this. (I use
ConTeXt mainly with XML input sources.)

Just in case it helps,

Pablo

Hi,

I updated the page about URLs. Reading the text, I found the following
sentence which -- in my opinion -- does not correspond with the current
behaviour:

"You can use \url[aurl] as well, which behaves like \from[#1]."

I tried it but the \url[aurl] is not printed out in green colour as 
well as

other similar links and, moreover, it seems not to be clickable.
Could somebody confirm or disprove it?

Are there some other predefined "\letterxxx" commands?

Is (and how) possible to change the name of page from Url to URL?

this probably has come up several times now, anyway


\getfiguredimensions[test.pdf]
\dorecurse {\noffigurepages} {
 \getfiguredimensions[test.pdf][page=#1]
 \figurenaturalwidth
,\figurenaturalheight,\figureorientation,\figurerotation\par
}

in lua you can either use the img library (see luatex manual) or context
helpers

 local data = figures.push("foo.pdf")
 figures.identify()
 figures.check()
 figures.pop()
inspect(data)

i'll add:

function figures.getinfo(name,page)
 if type(name) == "string" then
 name = { name = name, page = page }
 end
 if name.name then
 local data = figures.push(name)
 figures.identify()
 figures.check()
 figures.pop()
 return data
 end
end

so that one can do

local n = "ms.pdf"
local d = figures.getinfo(n)

if d then
 for i=1,d.used.pages do
 local p = figures.getinfo(n,i)
 if p then
 local u = p.used
 print(u.width,u.height,u.orientation)
 end
 end
end

[NTG-context] having all lines with \setuptyping

Dear list,

I have the following sample:

\setuptyping[TEX][lines=no]
\definetyping[TEXlines][lines=yes, option=TEX]
\starttext
\startxtable[frame=off,option=stretch]\startxrow
\startxcell\startTEX
\starttext
Esto
es un
único párrafo.



Y aquí está el segundo.

Y el tercero.
\stoptext
\stopTEX\stopxcell
\startxcell\startTEXlines
\starttext
Esto
es un
único párrafo.



Y aquí está el segundo.

Y el tercero.
\stoptext
\stopTEXlines\stopxcell
\stopxrow\stopxtable
\stoptext

I need to show that there is more than one blank line where required.

I assumed \setuptyping[lines=yes] should do that.

Am I wrong or is there a bug here? (I’m using beta from 2017.08.15 12:35.)

Many thanks for your help,

Pablo

  drawoptions(withcolor \MPcolor{darkred}) ;

  setbounds currentpicture to p ;
\stopuniqueMPgraphic
