31.3 Indentation for Programs
The best way to keep a program properly indented is to use Emacs to reindent it as you change it. Emacs has commands to indent properly either a single line, a specified number of lines, or all of the lines inside a single parenthetical grouping.
31.3.1 Basic Program Indentation Commands | Indenting a single line. | |
31.3.2 Indenting Several Lines | Commands to reindent many lines at once. | |
31.3.3 Customizing Lisp Indentation | Specifying how each Lisp function should be indented. | |
31.3.4 Commands for C Indentation | Extra features for indenting C and related modes. | |
31.3.5 Customizing C Indentation | Controlling indentation style for C and related modes. |
Emacs also provides a Lisp pretty-printer in the library pp
