pretty-printer

Arguments: development-configuration

Returns the value of the pretty-printer property of development-configuration. The current development configuration is the value of (configuration *ide-system*) (see configuration and *ide-system*).

This property determines whether to re-wrap lines of text when re-indenting (by choosing Edit | Reindent). The value can be :reindent and :pretty-print.

If the value is :reindent, the indentation of each line will be adjusted without rearranging words onto different lines.

If the value is :pretty-print, the whole expression will be re-pretty-printed, which may change which words are grouped together on the same line. Warning: when the value is :pretty-print, any internal comments in a top-level form will be lost whenever the Edit | Reindent command is used on it, because this option causes the form to be read and then pretty-printed anew into the editor window. Also, the :pretty-print option will not properly reproduce the original source code if the code contains reader macro calls that return objects that do not print readably; for example, #.(make-position 0 0) would be reprinted non-readably as #<position 0 0>. (Use of such position constants is deprecated; see with-positions.) Therefore, this option is probably useful only for uncommented plain vanilla source code that needs to be re-wrapped.

This value can be set on the Editor tab on the Options dialog (displayed with Tools | Options).

You can examine and change configuration options in general with the inspector. Choose Tools | Inspect System Data | IDE Configuration Options.

Suppose you have this form in an editor:

(defun foo (a
     b
         c)  ;; args are a b c
          (+ a b 
      c))

If pretty-printer is :reindent, choosing Edit | Reindent while the form is selected produces:

(defun foo (a
            b
            c)  ;; args are a b c
   (+ a b 
      c)

If pretty-printer is :pretty-print, choosing Edit | Reindent while the form is selected produces (notice that the comment has disappeared):

(defun foo (a b c) (+ a b c))
