Name of the active buffer

Name of the active buffer

[hfleming]

Suppose I want to run, from emacs, the program "prog" with the active buffer,
"buffer", say, as argument.
Of course I can do "Meta-! prog buffer". Some editors, however, have a
default name for the active buffer. In vi, for instance, one can do ":! prog
%" . In ultraedit, the buffer is called "%f". How can we do that in emacs?

Thanks!

If it is a "normal" command that reads from standard input when no file 
name argument is given: C-x h M-| prog RET

Maybe this is what you are looking for:

buffer-name is a built-in function in `C source code'.
(buffer-name &optional BUFFER)

Return the name of BUFFER, as a string.
With no argument or nil as argument, return the name of the current buffer.

I assume you want to pass the buffer /file/ name as an argument to the
program, not the name.

Normally this is what you want for the compile command. It's a good idea
to use that even if the program is not strictly a compiler.

There is no built-in feature for taking the file name and using it with
M-x compile. One way to do it is to have a local variable in the file:

    compile-command: program and arguments...

See <http://www.emacswiki.org/cgi-bin/wiki/CompileCommand> for possible
other ways.
