| 29 ;; This package provides Emacs support for Octave. | |
| 30 ;; It defines Octave mode, a major mode for editing | |
| 31 ;; Octave code. | |
| 32 | |
| 33 ;; The file octave-hlp.el provides `octave-help', a facility for looking up | |
| 34 ;; documentation on a symbol in the Octave info files. | |
| 35 | |
| 36 ;; The file octave-inf.el contains code for interacting with an inferior | |
| 37 ;; Octave process using comint. | |
| 38 | |
| 39 ;; See the documentation of `octave-mode', `octave-help' and | |
| 40 ;; `run-octave' for further information on usage and customization. | |

| 424 | |
| 425 The latest released version of Octave is always available via anonymous | |

| 437 ============================================== | |
| 438 | |
| 6976 | 439 `octave-auto-indent' |
| 3069 | 440 Non-nil means indent current line after a semicolon or space. |
| 441 Default is nil. | |
| 442 | |
| 6976 | 443 `octave-auto-newline' |
| 2617 | 444 Non-nil means auto-insert a newline and indent after a semicolon. |
| 445 Default is nil. | |
| 446 | |
| 6976 | 447 `octave-blink-matching-block' |
| 2617 | 448 Non-nil means show matching begin of block when inserting a space, |
| 449 newline or semicolon after an else or end keyword. Default is t. | |
| 450 | |
| 6976 | 451 `octave-block-offset' |
| 2617 | 452 Extra indentation applied to statements in block structures. |
| 453 Default is 2. | |
| 454 | |
| 6976 | 455 `octave-continuation-offset' |
| 2617 | 456 Extra indentation applied to Octave continuation lines. |
| 457 Default is 4. | |
| 458 | |
| 6976 | 459 `octave-continuation-string' |
| 2617 | 460 String used for Octave continuation lines. |
| 461 Default is a backslash. | |
| 462 | |
| 6976 | 463 `octave-send-echo-input' |
| 2617 | 464 Non-nil means always display `inferior-octave-buffer' after sending a |
| 465 command to the inferior Octave process. | |
| 466 | |
| 6976 | 467 `octave-send-line-auto-forward' |
| 2617 | 468 Non-nil means always go to the next unsent line of Octave code after |
| 469 sending a line to the inferior Octave process. | |
| 470 | |
| 6976 | 471 `octave-send-echo-input' |
| 2617 | 472 Non-nil means echo input sent to the inferior Octave process. |
| 473 | |
| 474 Turning on Octave mode runs the hook `octave-mode-hook'. | |
| 475 | |
| 476 To begin using this mode for all `.m' files that you edit, add the | |
| 477 following lines to your `.emacs' file: | |
| 478 | |
| 6976 | 479 (add-to-list 'auto-mode-alist '(\"\\\\.m\\\\'\" . octave-mode)) |
| 2617 | 480 |
| 6976 | 481 To automatically turn on the abbrev and auto-fill features, |
| 2617 | 482 add the following lines to your `.emacs' file as well: |
| 483 | |
| 484 (add-hook 'octave-mode-hook | |
| 485 (lambda () | |
| 486 (abbrev-mode 1) | |

| 490 an Octave mode buffer. | |
