408 This mode makes it easier to write Octave code by helping with
409 indentation, doing some of the typing for you (with Abbrev mode) and by
410 showing keywords, comments, strings, etc. in different faces (with
411 Font Lock mode on terminals that support it).
413 Octave itself is a high-level language, primarily intended for numerical
414 computations. It provides a convenient command line interface for
415 solving linear and nonlinear problems numerically. Function definitions
416 can also be stored in files, and it can be used in a batch mode (which
417 is why you need this mode!).
419 The latest released version of Octave is always available via anonymous
420 ftp from ftp.octave.org in the directory `/pub/octave'. Complete
421 source and binaries for several popular systems are available.
423 Type \\[list-abbrevs] to display the built-in abbrevs for Octave keywords.
430 Variables you can use to customize Octave mode
431 ==============================================
434 Non-nil means indent current line after a semicolon or space.
437 `octave-auto-newline'
438 Non-nil means auto-insert a newline and indent after a semicolon.
441 `octave-blink-matching-block'
442 Non-nil means show matching begin of block when inserting a space,
443 newline or semicolon after an else or end keyword. Default is t.
445 `octave-block-offset'
446 Extra indentation applied to statements in block structures.
449 `octave-continuation-offset'
450 Extra indentation applied to Octave continuation lines.
453 `octave-continuation-string'
454 String used for Octave continuation lines.
455 Default is a backslash.
457 `octave-send-echo-input'
458 Non-nil means always display `inferior-octave-buffer' after sending a
459 command to the inferior Octave process.
461 `octave-send-line-auto-forward'
462 Non-nil means always go to the next unsent line of Octave code after
463 sending a line to the inferior Octave process.
465 `octave-send-echo-input'
466 Non-nil means echo input sent to the inferior Octave process.
468 Turning on Octave mode runs the hook `octave-mode-hook'.
470 To begin using this mode for all `.m' files that you edit, add the
471 following lines to your `.emacs' file:
473 (add-to-list 'auto-mode-alist '(\"\\\\.m\\\\'\" . octave-mode))
475 To automatically turn on the abbrev and auto-fill features,
476 add the following lines to your `.emacs' file as well:
478 (add-hook 'octave-mode-hook
483 To submit a problem report, enter \\[octave-submit-bug-report] from \
484 an Octave mode buffer.
485 This automatically sets up a mail buffer with version information
486 already added. You just need to add a description of the problem,
487 including a reproducible test case and send the message."
