For such a document, it can be very useful to put code snippets into
buffers and then use
\typeTEXbuffer
or
\typeLUAbuffer
and then
\getbuffer

I don't know how to answer your questions with the default syntax 
highlighting in ConTeXt, but are you willing to consider t-vim module for 
typesetting code. The output for your example is attached.


All you need to do is add the following in the document preamble:

\usemodule[vim]
\definevimtyping[TEX][syntax=context]
\definevimtyping[XML][syntax=xml]
\definevimtyping[LUA][syntax=lua]

If you have lot of code snippets, you may want to create a directory to 
store temporary files. You can do this using


\setupvimtyping[directory=output]

and then create a directory called "output" in the folder from which you 
run ConTeXt.

[NTG-context] (again) issues with typing

2017-08-16 Thread Pablo Rodriguez

Dear list,

sorry for insisting, but I need to solve this.

I have to explain to newcomers (in my Spanish introduction to ConTeXt)
what comments are and multiple lines don’t affect the final PDF document.

I have the following sample:

\setuptyping[lines=yes]
\starttext
\startTEXpage[offset=1em]
\startTEX
This is text. % and this is a comment
\stopTEX

\startXML
This is text.
\stopXML

\startLUA
if code=="code" then --this is a comment

--[[
this is a

multiline comment
--]]

---[[
this isn’t a


multiline comment
--]]
\stopLUA
\stopTEXpage
\stoptext

I have three questions:

1. How do I enable that multiple blank lines are displayed as more than
a single one?

The Lua code contains one, two and three blank lines and they are
displayed always as separation from single lines.

I thought lines=yes should do that, but it doesn’t.

2. I accidentally discovered that the block comment opening (--[[)
removes break with next line. I think it should be fixed.

3. The most important issue is that the whole comment (both markers and
content) is displayed with \darkyellow.

I wonder why comments aren’t display in typing as in any other editor.
All comment characters should be displayed the same, since none of them
would affect to the final output.

How can I get the same color for the whole comment (again, both markers
and content)?

Many thanks for your help,

Pablo

Hi Hraban,

I checked it yesterday, but I didn’t found a solution.

All I can say is that if grid is enabled, (at least) a blank line before
and after \section is added. See yourself:

 \showgrid
 \setuplayout[grid=yes,]
 \setuphead[section][page=no,before=,after=]

 \starttext

 \startchapter[title={Authors}]

 \startsection[title={Knuth}]
 \input knuth
 \stopsection

 \startsection[title={Tufte}]
 \input tufte
 \stopsection

 \setuphead[section]
 [before={\blackrule[width=\textwidth,color=green,
   height=\lineheight]},
 after={\blackrule[width=\textwidth,color=red, height=\lineheight]}]

 \startsection[title={Hawking}]
 \input hawking
 \stopsection

 \startsection[title={Zapf}]
 \input zapf
 \stopsection

 \stopchapter

 \stoptext

I would say this might be a bug. But someone with more ConTeXt knowledge
should confirm my assumption.

Sorry for not providing actual help,

Pablo


Well, for this example you can do it with a simple hack:

   \setuphead[section][page=no,before={},after={\blank[-1*line]}]

You will have to test how that works for you in a more complex document.

Hi Hraban,

if I get your question, the reply would be:

  \definehighlight[emph][style=\em]
  \setupbodyfontenvironment[default][em=italic]

Was this what you needed?

[NTG-context] context sensitive highlight styles

2017-08-16 Thread Henning Hraban Ramm

In my current project, section titles are typeset in SansBold while the body 
text (and that of the ToC) is roman.

How can I define \definehighlight[emph], so that I get SansBoldItalic in titles 
and SerifItalic in body text and ToC? (Body text is not a problem.)

MNWE:

\setuphead[chapter][page=yes,style={\ss\bfc}]
\setuphead[section][page=no,style={\ss\bfa}]
\definehighlight[emph][style=\it]

\starttext

\completecontent

\startchapter[title={My book \emph{\ConTeXt\ for Runaways}}]

\startsection[title={Knuth, \emph{the professor}}]
\input knuth

this probably has come up several times now, anyway


\getfiguredimensions[test.pdf]
\dorecurse {\noffigurepages} {
 \getfiguredimensions[test.pdf][page=#1]
 \figurenaturalwidth

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)
