# Re: [NTG-context] Including part of a program source file

The verbatim commands have a range key which let you select parts of the code, you can use line numbers to include a small block (e.g. range={3,10} or range {3,+7})
or you put labels in your code.

\startbuffer
% cmd:one:begin
\define\FirstCommand
{\dosingleempty\doFirstCommand}

\def\doFirstCommand[#1]%
{This is the definition for the first command}
% cmd:one:end

% cmd:two:begin
\define\SecondCommand
{\dosingleempty\doSecondCommand}

\def\doSecondCommand[#1]%
{This is the definition for the second command}
% cmd:two:end
\stopbuffer

\starttext
\typebuffer[range={cmd:two:begin,cmd:two:end}]
\stoptext

I am writing some notes using ConTeXt, which involves displaying parts
of some program source files. At present, I am manually cutting and
pasting the parts into the ConTeXt file. Is it possible to make ConTeXt
do that for me? I am thinking of including each part of the Coq sources
between tags like this:

------------------------------------------------------------
\$ cat src-file
<tag-1>
part_to_be_included_1
</tag-2>

<tag-2>
part_to_be_included_2
</tag-2>
------------------------------------------------------------

I would like to say something like

\IncludePart{src-file}{tag-1}

in my ConTeXt file to get

part_to_be_included_1

at that place in the PDF output after I run context'. I would

Thanks,
Raghu.
