Parallel output of source data

Parallel output of source data

[Procházka Lukáš Ing.]

Hello,

is there a way to let ConTeXt to flush the input stream in parallel into an output buffer, like:

----
\starttext

A

\startoutput{Test.mkiv}
   Hello!
   \startitemize
     \item Item
   \stopitemize
\stopoutput

B

\stoptext
----

which would produce:

---- Test.mkiv
   Hello!
   \startitemize
     \item Item
   \stopitemize
----

Thank you in advance.

Best regards,

Lukas

You can use a buffer to store content and save it in a external file.

\unexpanded\def\startcontentexport
   {\dosingleempty\dostartcontentexport}

\def\dostartcontentexport[#1]%
   {\iffirstargument
      \edef\contentexportfile{#1}%
    \else
      \let\contentexportfile\empty
    \fi
    \grabbufferdata[contentexport][startcontentexport][stopcontentexport]}

\def\stopcontentexport
   
{\doifsomething{\contentexportfile}{\savebuffer[list=contentexport,prefix=no,file=\contentexportfile]}%
    \getbufferdata[contentexport]}

\starttext

A

\startcontentexport[Test.mkiv]
   Hello!
   \startitemize
     \item Item
   \stopitemize
\stopcontentexport

B

\stoptext

Hello,

I tried to \let shortcuts for \startcontentexport and \stopcontentexport, but Ctx run fails.

I guess this is a basic misunderstanding, but - why?

----
\unexpanded\def\startcontentexport{\dosingleempty\dostartcontentexport}

\def\dostartcontentexport[#1]%
{\iffirstargument
   \edef\contentexportfile{#1}%
   \else
   \let\contentexportfile\empty
   \fi
   \grabbufferdata[contentexport][startcontentexport][stopcontentexport]
}

\def\stopcontentexport{%
   \doifsomething{\contentexportfile}{\savebuffer[list=contentexport,prefix=no,file=\contentexportfile]}%
   \getbufferdata[contentexport]
}

\let\bX=\startcontentexport % <---- Use of these two "shortcuts" is not possible,
\let\eX=\stopcontentexport  % <---- I'm getting : ! TeX capacity exceeded, sorry [input stack size=10000]

\starttext

   A

   \startcontentexport[t~.out.mkiv]
     Hello!
     \startitemize
     \item Item
     \stopitemize
   \stopcontentexport

   B

   \bX[t2~.out.mkiv]
     Ahoj
   \eX

\stoptext
----

HSo how to define "shortcuts" properly?

Best regards,

Lukas

Hi Lukas,

when you create the buffer with the grabbufferdata-command you already set
the delimiter for the environment with the third argument, in the 
example below
this is the \stopcontentexport command.

To have different start/stop-commands for your environment means you have
to change all names in the implementation of the contentxport-environment.

%%%%%%
\unexpanded\def\bH{....}

\def\dobH[#1]%
    {...
     \grabbufferdata[...][bH][eH]}

\def\eH
   {....}
%%%%%%

thank you for the explanation! - Much clearer for me how buffers work!

impossible ... just define an extra grabbuffer


what has this to do with parallel texts
