Does Emacs have a compiler?
Emacs can run compilers for languages such as C and Fortran, feeding the compilation log into an Emacs buffer. This reads a shell command line using the minibuffer, and then executes the command by running a shell as a subprocess (or inferior process) of Emacs. The output is inserted in a buffer named *compilation* .
How do I open Emacs files?
To execute a file of Emacs Lisp code, use M-x load-file . This command reads a file name using the minibuffer and then executes the contents of that file as Lisp code. It is not necessary to visit the file first; in any case, this command reads the file as found on disk, not text in an Emacs buffer.
How do I compile and run code in Emacs?

How do I run a Scheme file?

Where does the COMPILE command go in Emacs?
If you have done M-x compile before, the command that you specified is automatically stored in the variable compile-command; this is used as the default the next time you type M-x compile. A file can also specify a file-local value for compile-command (see File Variables ).
Which is the default value for the COMPILE command?
The variable ‘compile-command’ holds the default value for the `M-x compile’ command. The default value is “make -k” which is good enough for most projects, because you’ll either have a Makefile, or you can rely on the default rules within make.
