407 This mode makes it easier to write Octave code by helping with
408 indentation, doing some of the typing for you (with Abbrev mode) and by
409 showing keywords, comments, strings, etc. in different faces (with
410 Font Lock mode on terminals that support it).
412 Octave itself is a high-level language, primarily intended for numerical
413 computations. It provides a convenient command line interface for
414 solving linear and nonlinear problems numerically. Function definitions
415 can also be stored in files, and it can be used in a batch mode (which
416 is why you need this mode!).
418 The latest released version of Octave is always available via anonymous
419 ftp from ftp.octave.org in the directory `/pub/octave'. Complete
420 source and binaries for several popular systems are available.
422 Type \\[list-abbrevs] to display the built-in abbrevs for Octave keywords.
429 Variables you can use to customize Octave mode
430 ==============================================
433 Non-nil means indent current line after a semicolon or space.
436 `octave-auto-newline'
437 Non-nil means auto-insert a newline and indent after a semicolon.
440 `octave-blink-matching-block'
441 Non-nil means show matching begin of block when inserting a space,
442 newline or semicolon after an else or end keyword. Default is t.
444 `octave-block-offset'
445 Extra indentation applied to statements in block structures.
448 `octave-continuation-offset'
449 Extra indentation applied to Octave continuation lines.
452 `octave-continuation-string'
453 String used for Octave continuation lines.
454 Default is a backslash.
456 `octave-send-echo-input'
457 Non-nil means always display `inferior-octave-buffer' after sending a
458 command to the inferior Octave process.
460 `octave-send-line-auto-forward'
461 Non-nil means always go to the next unsent line of Octave code after
462 sending a line to the inferior Octave process.
464 `octave-send-echo-input'
465 Non-nil means echo input sent to the inferior Octave process.
467 Turning on Octave mode runs the hook `octave-mode-hook'.
469 To begin using this mode for all `.m' files that you edit, add the
470 following lines to your `.emacs' file:
472 (add-to-list 'auto-mode-alist '(\"\\\\.m\\\\'\" . octave-mode))
474 To automatically turn on the abbrev and auto-fill features,
475 add the following lines to your `.emacs' file as well:
477 (add-hook 'octave-mode-hook
482 To submit a problem report, enter \\[octave-submit-bug-report] from \
483 an Octave mode buffer.
484 This automatically sets up a mail buffer with version information
485 already added. You just need to add a description of the problem,
486 including a reproducible test case and send the message."
