[NTG-context] Getting the content of source lines in a \startlines \stoplines env?

2013-02-04 Thread Ingo Hohmann 

Hi,

in another thread I got an answer to the question, how to format lines 
in an environment automatically.
Is there a way to get the content of source lines? For example, to save 
the line content into a variable?



Thank you in advance,

Ingo

You can save the content in a buffer and process the content with Lua.

\startluacode

userdata  = userdata  or { }
userdata.linescontent = userdata.linescontent or { }

local linescontent = userdata.linescontent

function linescontent.process()
local lines = string.splitlines(buffers.getcontent(linescontent))
context.startlines()
for i=1,#lines do
local l = lines[i]
if i == 1 then
context({\\bf %s},l)
context(true)
elseif i == 2 then
context({\\tt %s},l)
context(true)
else
context(%s,l)
context(true)
end
end
context.stoplines()
end

\stopluacode

\def\startlinescontent
  {\grabbufferdata[linescontent][startlinescontent][stoplinescontent]}

\def\stoplinescontent
  {\ctxlua{userdata.linescontent.process()}}

\starttext

\startlinescontent
One
Two
Three
Four
Five
Six
\stoplinescontent

\stoptext

What does context(true) do?
