With \setbuffer[ABUFFER] .. \endbuffer I can program a macro to put

But is it possible to add something at the end of this buffer at a 
later moment?


You can use the “buffers.append” and “buffers.prepend” functions to add 
text to a buffer.


\starttext

\startbuffer[a]
First
\stopbuffer

\startbuffer[b]
Second
\stopbuffer

\startbuffer[c]
Third
\stopbuffer

\startluacode

buffers.append("b",buffers.getcontent("c"))

buffers.prepend("b",buffers.getcontent("a"))

\stopluacode

\getbuffer[b]

\stoptext

or just getbuffer[a,b,c]

[NTG-context] add to \setbuffer

With \setbuffer[ABUFFER] .. \endbuffer I can program a macro to put something

But is it possible to add something at the end of this buffer at a later moment?
