Hi all,
I have a module with a envrionment defined in the following way:
\def\startFOO#1\stopFOO{...#1...}
I try currently to write a command \defineFOO[MYFOO] that expands to
my
already created environment.
\startMYFOO#1\stopMYFOO -> \startFOO#1\stopFOO
I know it is possible to make this in the following way:
\def\startMYFOO#1\stopMYFOO{\startFOO#1\stopFOO}
but this not what I want.
Something like this
\def\defineFOO[#1]%
   {\setvalue{\c!start#1}{\startFOO}
    \setvalue{\c!stop#1} {\stopFOO}}
Hi Aditya,
this can only be used if you define your environment in this way:
\def\startFOO{...}
\def\stopFoo{...}
I defined my environment in this way:
\def\startFOO#1\stopFOO{...}
This means TeX reads everything from \startFOO till \stopFOO and looks
afterwards at the replacement text.
I am not sure how something like that you work.

I used tried the first way with saving the content into a buffer and
using the buffer content.
If you want to write to a buffer and later use it, there are low level
macros to define your own buffer commands. Have a look at the R module
to see an example. Depending on your usage, you will have to keep
track of the buffer numbers on your own.

Hi Aditya,
I tried to use a buffer but you cannot make something like this:
\starttext
\placefigure
{}
{\startbuffer{mybuffer}
 Floating text from a buffer
 \stopbuffer
 \getbuffer{mybuffer}}
\stoptext
with content saved in a buffer.
no, there is \setbuffer but in general (at least not in context mkii)
buffers are to be defined at the outer level
...
It's not a real problem but I wanted to know if it is possible to
define a environment in the way I wanted.
Hi Hans,

I looked into core-buf but this was not what I was looking for.

What I want is a command like this:

\def\defineFOO[#1]%
  {\expandafter\def\csname start#1\endcsname##1\csname stop#1\endcsname%
     {\startFOO##1\stopFOO}}

and after I wrote

\defineFOO[MYFOO]

I can use the next command

\startMYFOO...\stopMYFOO
