Executing Lisp Expressions
Emacs has several different major modes for Lisp and Scheme. They are
the same in terms of editing commands, but differ in the commands for
executing Lisp expressions. Each mode has its own purpose.
- Emacs-Lisp mode
- The mode for editing source files of programs to run in Emacs Lisp.
This mode defines C-M-x to evaluate the current defun.
See Lisp Libraries.
- Lisp Interaction mode
- The mode for an interactive session with Emacs Lisp. It defines
C-j to evaluate the sexp before point and insert its value in the
buffer. See Lisp Interaction.
- Lisp mode
- The mode for editing source files of programs that run in Lisps other
than Emacs Lisp. This mode defines C-M-x to send the current defun
to an inferior Lisp process. See External Lisp.
- Inferior Lisp mode
- The mode for an interactive session with an inferior Lisp process.
This mode combines the special features of Lisp mode and Shell mode
(see Shell Mode).
- Scheme mode
- Like Lisp mode but for Scheme programs.
- Inferior Scheme mode
- The mode for an interactive session with an inferior Scheme process.
Most editing commands for working with Lisp programs are in fact
available globally. See Programs.
