@chapter Overview
|
||||
|
||||
The development of Octave code can greatly be facilitated using Emacs
|
||||
with Octave mode, a major mode for editing Octave files which can
|
||||
e.g.@: automatically indent the code, do some of the typing (with
|
||||
Abbrev mode) and show keywords, comments, strings, etc.@: in different
|
||||
faces (with Font-lock mode on devices that support it).
|
||||
|
||||
It is also possible to run Octave from within Emacs, either by
|
||||
directly entering commands at the prompt in a buffer in Inferior
|
||||
Octave mode, or by interacting with Octave from within a file with
|
||||
Octave code. This is useful in particular for debugging Octave code.
|
||||
|
||||
@node Using Octave Mode
|
||||
@chapter Using Octave Mode
|
||||
@cindex Using Octave Mode
|
||||
|
||||
In Octave mode, the following special Emacs commands can be used in
|
||||
addition to the standard Emacs commands.
|
||||
|
||||
@table @kbd
|
||||
@item C-M-j
|
||||
@kindex C-M-j
|
||||
@findex octave-indent-new-comment-line
|
||||
@vindex octave-continuation-string
|
||||
Break Octave line at point, continuing comment if within one. Insert
|
||||
@code{octave-continuation-string} before breaking the line unless
|
||||
inside a list. Signal an error if within a single-quoted string.
|
||||
|
||||
@item C-c ;
|
||||
@kindex C-c ;
|
||||
@findex octave-update-function-file-comment
|
||||
Query replace function names in function file comment.
|
||||
|
||||
@item C-c C-p
|
||||
@kindex C-c C-p
|
||||
@findex octave-previous-code-line
|
||||
Move one line of Octave code backward, skipping empty and comment
|
||||
lines (@code{octave-previous-code-line}). With numeric prefix
|
||||
argument @var{n}, move that many code lines backward (forward if
|
||||
@var{n} is negative).
|
||||
|
||||
@item C-c C-n
|
||||
@kindex C-c C-n
|
||||
@findex octave-next-code-line
|
||||
Move one line of Octave code forward, skipping empty and comment lines
|
||||
(@code{octave-next-code-line}). With numeric prefix argument @var{n},
|
||||
move that many code lines forward (backward if @var{n} is negative).
|
||||
|
||||
@item C-c C-a
|
||||
@kindex C-c C-a
|
||||
@findex octave-beginning-of-line
|
||||
Move to the beginning of the physical line
|
||||
(@code{octave-beginning-of-line}). If point is in an empty or comment
|
||||
line, simply go to its beginning; otherwise, move backwards to the
|
||||
beginning of the first code line which is not inside a continuation
|
||||
statement, i.e., which does not follow a code line ending in
|
||||
@samp{...} or @samp{\}, or is inside an open parenthesis list.
|
||||
|
||||
@item C-c C-e
|
||||
@kindex C-c C-e
|
||||
@findex octave-end-of-line
|
||||
Move to the end of the physical line (@code{octave-end-of-line}). If
|
||||
point is in a code line, move forward to the end of the first Octave
|
||||
code line which does not end in @samp{...} or @samp{\} or is inside an
|
||||
open parenthesis list. Otherwise, simply go to the end of the current
|
||||
line.
|
||||
|
||||
@item C-c M-C-h
|
||||
@kindex C-c M-C-h
|
||||
@findex octave-mark-block
|
||||
Put point at the beginning of this block, mark at the end
|
||||
(@code{octave-mark-block}). The block marked is the one that contains
|
||||
point or follows point.
|
||||
|
||||
@item C-c ]
|
||||
@kindex C-c ]
|
||||
Close the current block on a separate line (@code{smie-close-block}).
|
||||
An error is signaled if no block to close is found.
|
||||
|
||||
@item C-c C-f
|
||||
@kindex C-c C-f
|
||||
@findex octave-insert-defun
|
||||
Insert a function skeleton, prompting for the function's name, arguments
|
||||
and return values which have to be entered without parentheses
|
||||
(@code{octave-insert-defun}).
|
||||
@noindent
|
||||
in one of your Emacs startup files.
|
||||
@end table
|
||||
|
||||
A common problem is that the @key{RET} key does @emph{not} indent the
|
||||
line to where the new text should go after inserting the newline. This
|
||||
is because the standard Emacs convention is that @key{RET} (aka
|
||||
@kbd{C-m}) just adds a newline, whereas @key{LFD} (aka @kbd{C-j}) adds a
|
||||
newline and indents it. This is particularly inconvenient for users with
|
||||
keyboards which do not have a special @key{LFD} key at all; in such
|
||||
cases, it is typically more convenient to use @key{RET} as the @key{LFD}
|
||||
key (rather than typing @kbd{C-j}).
|
||||
|
||||
You can make @key{RET} do this by adding
|
||||
@lisp
|
||||
(define-key octave-mode-map "\C-m"
|
||||
'octave-reindent-then-newline-and-indent)
|
||||
@end lisp
|
||||
@noindent
|
||||
to one of your Emacs startup files. Another, more generally applicable
|
||||
solution is
|
||||
@lisp
|
||||
(defun RET-behaves-as-LFD ()
|
||||
(let ((x (key-binding "\C-j")))
|
||||
(local-set-key "\C-m" x)))
|
||||
(add-hook 'octave-mode-hook 'RET-behaves-as-LFD)
|
||||
@end lisp
|
||||
@noindent
|
||||
(this works for all modes by adding to the startup hooks, without
|
||||
having to know the particular binding of @key{RET} in that mode!).
|
||||
Similar considerations apply for using @key{M-RET} as @key{M-LFD}. As
|
||||
@email{bwarsaw@@cnri.reston.va.us, Barry A. Warsaw} says in the
|
||||
documentation for his @code{cc-mode}, ``This is a very common
|
||||
question. @code{:-)} If you want this to be the default behavior,
|
||||
don't lobby me, lobby RMS!''
|
||||
|
||||
The following variables can be used to customize Octave mode.
|
||||
|
||||
@vtable @code
|
||||
@item octave-blink-matching-block
|
||||
Non-@code{nil} means show matching begin of block when inserting a space,
|
||||
newline or @samp{;} after an else or end keyword. Default is @code{t}.
|
||||
This is an extremely useful feature for automatically verifying that the
|
||||
keywords match---if they don't, an error message is displayed.
|
||||
|
||||
@item octave-block-offset
|
||||
Extra indentation applied to statements in block structures.
|
||||
Default is 2.
|
||||
|
||||
@item octave-continuation-offset
|
||||
Extra indentation applied to Octave continuation lines.
|
||||
Default is 4.
|
||||
|
||||
@item octave-font-lock-texinfo-comment
|
||||
Highlight texinfo comment blocks. The default value is @code{t}.
|
||||
@end vtable
|
||||
|
||||
If Font Lock mode is enabled, Octave mode will display
|
||||
|
||||
@itemize @bullet
|
||||
@item
|
||||
strings in @code{font-lock-string-face}
|
||||
|
||||
@item
|
||||
comments in @code{font-lock-comment-face}
|
||||
|
||||
@item
|
||||
the Octave reserved words (such as all block keywords) and the text
|
||||
functions (such as @samp{cd} or @samp{who}) which are also reserved
|
||||
using @code{font-lock-keyword-face}
|
||||
|
||||
@item
|
||||
the built-in operators (@samp{&&}, @samp{==}, @dots{}) using
|
||||
@code{font-lock-reference-face}
|
||||
|
||||
@item
|
||||
and the function names in function declarations in
|
||||
@code{font-lock-function-name-face}.
|
||||
|
||||
@item
|
||||
Function comments blocks in @code{octave-function-comment-block}
|
||||
@end itemize
|
||||
|
||||
@cindex Imenu Support
|
||||
There is also rudimentary support for Imenu (@pxref{Imenu,,, emacs,
|
||||
The GNU Emacs Manual}). Currently, function names can be indexed.
|
||||
|
||||
@cindex ElDoc Mode Support
|
||||
@vindex octave-eldoc-message-style
|
||||
ElDoc mode (@pxref{Lisp Doc,,, emacs, The GNU Emacs Manual}) is
|
||||
supported. By customizing @code{octave-eldoc-message-style} it can be
|
||||
changed from displaying one or multi line hints.
|
||||
|
||||
@c @cindex TAGS
|
||||
@c @cindex Emacs TAGS files
|
||||
@c @cindex @file{octave-tags}
|
||||
@c You can generate TAGS files for Emacs from Octave @file{.m} files using
|
||||
@c the shell script @file{octave-tags} that is installed alongside your copy of
|
||||
@c Octave.
|
||||
@c
|
||||
@vindex octave-mode-hook
|
||||
Customization of Octave mode can be performed by modification of the
|
||||
variable @code{octave-mode-hook}.

|
||||
@cindex Inferior Octave Mode
|
||||
|
||||
Octave mode provides commands for running an inferior
|
||||
Octave process in a special Emacs buffer. Use
|
||||
@lisp
|
||||
M-x run-octave
|
||||
@end lisp
|
||||
@noindent
|
||||
to directly start an inferior Octave process.
|
||||
|
||||
@vindex inferior-octave-buffer
|
||||
This will start Octave in a special buffer the name of which is
|
||||
specified by the variable @code{inferior-octave-buffer} and defaults
|
||||
to @file{*Inferior Octave*}. From within this buffer, you can
|
||||
interact with the inferior Octave process `as usual', i.e., by
|
||||
entering Octave commands at the prompt. The buffer is in Inferior
|
||||
Octave mode, which is derived from the standard Comint mode, a major
|
||||
mode for interacting with an inferior interpreter. See the
|
||||
documentation for @code{comint-mode} for more details, and use
|
||||
@kbd{C-h b} to find out about available special keybindings.
|
||||
|
||||
You can also communicate with an inferior Octave process from within
|
||||
files with Octave code (i.e., buffers in Octave mode), using the
|
||||
following commands.
|
||||
|
||||
@table @kbd
|
||||
@item C-c C-i l
|
||||
@kindex C-c C-i l
|
||||

|
||||
@vindex octave-send-line-auto-forward
|
||||
Send the current line to the inferior Octave process
|
||||
(@code{octave-send-line}). With positive prefix argument @var{n},
|
||||
send that many lines. If @code{octave-send-line-auto-forward} is
|
||||
non-@code{nil}, go to the next unsent code line.
|
||||
|
||||
@item C-c C-i b
|
||||
@kindex C-c C-i b
|
||||
@findex octave-send-block
|
||||

|
||||
(@code{octave-send-block}).
|
||||
|
||||
@item C-c C-i f
|
||||
@kindex C-c C-i f
|
||||
@findex octave-send-defun
|
||||
Send the current function to the inferior Octave process
|
||||
(@code{octave-send-defun}).
|
||||
|

@item C-c C-i r
|
||||
@kindex C-c C-i r
|
||||
@findex octave-send-region
|
||||
Send the region to the inferior Octave process
|
||||
(@code{octave-send-region}).
|
||||
|
||||
@item C-c C-i a
|
||||
@kindex C-c C-i a
|
||||
@findex octave-send-buffer
|
||||
Send the entire buffer to the inferior Octave process
|
||||
(@code{octave-send-buffer}). If the buffer is associated with a file
|
||||
then sourcing the buffer by using @kbd{C-c C-l}
|
||||
(@code{octave-source-file}) should be preferred.
|
||||
|
||||
@item C-c C-i s
|
||||
@kindex C-c C-i s
|
||||
@findex octave-show-process-buffer
|
||||
Make sure that `inferior-octave-buffer' is displayed
|
||||
(@code{octave-show-process-buffer}).
|
||||
|
||||
@item C-c C-i q
|
||||
@kindex C-c C-i q
|
||||
@findex octave-hide-process-buffer
|
||||
Delete all windows that display the inferior Octave buffer
|
||||
(@code{octave-hide-process-buffer}).
|
||||
|
||||
@item C-c C-i k
|
||||
@kindex C-c C-i k
|
||||
@findex octave-kill-process
|
||||
Kill the inferior Octave process and its buffer
|
||||
(@code{octave-kill-process}).
|
||||
|
||||
@item C-c C-l
|
||||
@kindex C-c C-l
|
||||
@findex octave-source-file
|
||||
Parse and execute the current file in the inferior Octave buffer
|
||||
(@code{octave-source-file}). This is done using Octave's
|
||||
@code{source} function.
|
||||
|
||||
@item M-.
|
||||
@kindex M-.
|
||||
@findex octave-find-definition
|
||||
@vindex octave-source-directories
|
||||
Find the definition of a function or variable. Functions implemented
|
||||
in C++ can be found if variable @code{octave-source-directories} is
|
||||
set correctly (@code{octave-find-definition}).
|
||||
|
||||
@item C-h d
|
||||
@kindex C-h d
|
||||
@findex octave-help
|
||||
@vindex octave-help-buffer
|
||||
Display the documentation for function (@code{octave-help}). The
|
||||
buffer name can be changed by customizing @code{octave-help-buffer}.
|
||||
|
||||
@item C-h a
|
||||
@kindex C-h a
|
||||
@findex octave-lookfor
|
||||
Search for a given string in all the first sentence of function help
|
||||
strings (@code{octave-lookfor}). With a @code{universal-argument} the
|
||||
entire help string is searched.
|
||||
|
||||
@end table
|
||||
|
||||
The effect of the commands which send code to the Octave process can be
|
||||
customized by the following variables.
|
||||
|
||||
@vtable @code
|
||||
@item octave-send-echo-input
|
||||
Non-@code{nil} means echo input sent to the inferior Octave process.
|
||||
Default is @code{t}.
|
||||
|
||||
@item octave-send-show-buffer
|
||||
Non-@code{nil} means display the buffer running the Octave process after
|
||||
sending a command (but without selecting it).
|
||||
Default is @code{t}.
|
||||
@end vtable
|
||||
|
||||
If you send code and there is no inferior Octave process yet, it will
|
||||
be started automatically.
|
||||
|
||||
@vindex inferior-octave-startup-args
|
||||
The startup of the inferior Octave process is highly customizable.
|
||||
The variable @code{inferior-octave-startup-args} can be used for
|
||||
specifying command lines arguments to be passed to Octave on startup
|
||||
as a list of strings. For example, to suppress the startup message
|
||||
and use `traditional' mode, set this to @code{("-q" "--traditional")}.
|
||||
You can also specify a startup file of Octave commands to be loaded on
|
||||
startup; note that these commands will not produce any visible output
|
||||
in the process buffer. Which file to use is controlled by the
|
||||
variable @code{inferior-octave-startup-file}. The default is
|
||||
@file{~/.emacs-octave} or if this file is not found
|
||||
@file{~/.emacs.d/init_octave.m}.
|
||||
|
||||
@vindex inferior-octave-prompt-read-only
|
||||
By customizing @code{inferior-octave-prompt-read-only} the prompt can
|
||||
be changed to be read only. The default value is the same as
|
||||
@code{comint-prompt-read-only}.
|
||||
|
||||
@vindex inferior-octave-mode-hook
|
||||
And finally, @code{inferior-octave-mode-hook} is run after starting
|
||||
the process and putting its buffer into Inferior Octave mode. Hence,
|
||||
if you like the up and down arrow keys to behave in the interaction
|
||||
buffer as in the shell, and you want this buffer to use nice colors,
|
||||
add
