Running Programs from Inside Emacs

Running Programs from Inside Emacs

[haziz]

When using emacs for programming in C, I know how to compile programs from inside emacs using Mx compile to invoke make -k which then compiles using gcc (I am running Linux Mint on a desktop machine at home and also use Mac OS X on a laptop). 

I have so far been unable to figure out how to "run" the resulting binary from inside emacs. I would like to be able to then run the binary file from inside emacs. So far I have had to exit emacs returning to my bash shell to run the binary by for e.g.    ./helloworld

Is it possible to get a shell prompt inside emacs and run the file in a secondary buffer within emacs?

I have tried to do a google search about this but most search results seem to talk only about Mx compile and stop there.

Thanks.

Sincerely,

Hany.

For non-interactive programs you can run them after the compilation:

M-x compile RET C-e && ./helloword RET

M-x shell RET

IMO, better is to use the Makefile.

all: helloworld.test

helloworld:
        cc helloworld.c -o helloworld

helloworld.test: helloworld
        ./helloworld

But if your './helloworld' is interactive console app and it ask you
for input you get can not pass input to it.

Or this possible in comiplation-mode?

Of course! M-x send-invisible <some input> RET.

No it is not.  For console applications, I advised to use M-x shell in
that case, but there are other ways.  

In emacs, you can use M-x term if the program
uses curses or in general terminal control codes beyond the dumbest
CR-LF.

Or, outside of emacs, you can launch your program via xterm or some
other terminal emulator:

    helloworld.test: helloworld
        xterm -e ./helloworld

Seems to me, that's inside emacs.
It's running under emacs from compilation mode.

You can  probably devise  something with gnuclient  running one  of the
emacs terminals.
