553 @deffn {Command} edit_history options\n\ |
|
554 If invoked with no arguments, @code{edit_history} allows you to edit the\n\ |
|
555 history list using the editor named by the variable @code{EDITOR}. The\n\ |
|
556 commands to be edited are first copied to a temporary file. When you\n\ |
|
557 exit the editor, Octave executes the commands that remain in the file.\n\ |
|
558 It is often more convenient to use @code{edit_history} to define functions \n\ |
|
559 rather than attempting to enter them directly on the command line.\n\ |
|
560 By default, the block of commands is executed as soon as you exit the\n\ |
|
561 editor. To avoid executing any commands, simply delete all the lines\n\ |
|
562 from the buffer before exiting the editor.\n\ |
|
563 \n\ |
|
564 The @code{edit_history} command takes two optional arguments specifying\n\ |
|
565 the history numbers of first and last commands to edit. For example,\n\ |
|
566 the command\n\ |
529
|
567 \n\ |
3332
|
568 @example\n\ |
|
569 edit_history 13\n\ |
|
570 @end example\n\ |
|
571 \n\ |
|
572 @noindent\n\ |
|
573 extracts all the commands from the 13th through the last in the history\n\ |
|
574 list. The command\n\ |
|
575 \n\ |
|
576 @example\n\ |
|
577 edit_history 13 169\n\ |
|
578 @end example\n\ |
|
579 \n\ |
|
580 @noindent\n\ |
|
581 only extracts commands 13 through 169. Specifying a larger number for\n\ |
|
582 the first command than the last command reverses the list of commands\n\ |
|
583 before placing them in the buffer to be edited. If both arguments are\n\ |
|
584 omitted, the previous command in the history list is used.\n\ |
