Hello,
octave-mode seemed to have been maintained both in GNU Octave and in
GNU Emacs for a while. The Emacs code has been removed from GNU Octave
(10856:dea165ff6d74) and it is now only maintained in GNU Emacs. But the
octave-mode manual is still part of GNU Octave
http://hg.savannah.gnu.org/hgweb/octave/file/1d58abc740c0/doc/interpreter/emacs.txi
It is not included in GNU Emacs and it is partially outdated. The GNU Octave
maintainers want to get rid of it and since octave-mode is maintained within
GNU Emacs it makes sense to move it to GNU Emacs.
It currently says "Copyright (C) 1996-2013 Kurt Hornik". I have contacted him
and he agreed to change the copyright to the FSF. What is the correct
procedure for this?
(Since he is the original author of octave-mode, I assume he has already
signed the fsf papers.)
Regards,
Rüdiger

I have checked the file history in GNU Octave and besides the original import
from Kurt Hornik it only seems to contain minor changes from
* John W. Eaton (has signed the fsf papers for Emacs)
* Rik <rik@octave.org>
* Rafael Laboissiere <rafael@debian.org>

You can't assume this, because it often seems to have happened in the
past that people assigned specific things rather than doing a blanket
assignment for "Emacs" (which would still only cover things they
explicitly wanted to contribute). And indeed the relevant entry in the
copyright.list file only says "Assigns octave.el and future changes.".
Does this include any associated manual? I dunno. It probably does, but
to be safe, I would suggest you ask assign@gnu for a definitive answer.
(Eg it seems slightly odd that the manual isn't in Emacs until now.)

Sounds like only the last two are potentially an issue.
(Though same comment as above for the first one.)
If "minor changes" means "less than ~ 15 lines worth of text from each
author remains in the latest version of the file", then there's no issue
here.
(Thanks for working on this, it definitely sounds like a good thing.)

Isn't fsf-records@gnu the address for such questions?

I've asked John W. Eaton (the GNU Octave maintainer) if there was a reason why
the manual wasn't moved to Emacs and he couldn't think of any.

That's the change contributed by Rafael.
http://hg.savannah.gnu.org/hgweb/octave/rev/a441d6681364#l5.1
It changes 3 lines.
Rik seems to have contributed more than 15 lines though.

I'll contact him to check if he has signed the fsf papers or is willing to do
so.

The one you're following. Indeed Kurt's changes are already covered.

Yup.
> * Rik <rik@octave.org>
> * Rafael Laboissiere <rafael@debian.org>
For Rik's changes, you might like to take a closer look at them, in case
some of his later changes supersede text he had contributed in earlier
changes, or have been superseded by other text. Or in case some of the
changes are "re-fill" (a pretty common occurrence in such text files).
But if he can be found and is willing to assign his copyright, it's even
better,
Stefan

He confirmed his willingness to change the copyright in a private e-mail. I
guess that's not enough to simply change it and commit it to Emacs. Does he
have to sign additional papers or is it enough if he makes a public statement
or contributes the diff?

I've contacted him. Most of his changes are whitespace fixes. I've counted
only 9 line changes which change actual content. Of which at least 4 are no
longer in my updated version. So maybe an assignment isn't even needed?

His paperwork already covers all changes he contributes to Emacs.
So his saying (over email) that he wants it in Emacs is sufficient.

Indeed.

If this is acceptable I'll push it to trunk. I'm not sure if I should
put Kurt Hornik as the author of the change.

+@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
+
+In Octave mode, the following special Emacs commands can be used in
+addition to the standard Emacs commands.
+
+@table @kbd
+@item C-h m
+Describe the features of Octave mode.
+
+@item LFD
+Reindent the current Octave line, insert a newline and indent the new
+line (@code{octave-reindent-then-newline-and-indent}). An abbrev before
+point is expanded if @code{abbrev-mode} is non-@code{nil}.
+
+@item TAB
+Indents current Octave line based on its contents and on previous
+lines (@code{indent-according-to-mode}).
+
+@item ;
+Insert an ``electric'' semicolon (@code{octave-electric-semi}). If
+@code{octave-auto-indent} is non-@code{nil}, reindent the current line.
+If @code{octave-auto-newline} is non-@code{nil}, automagically insert a
+newline and indent the new line.
+
+@item `
+Start entering an abbreviation (@code{octave-abbrev-start}). If Abbrev
+mode is turned on, typing @kbd{`C-h} or @kbd{`?} lists all abbrevs.
+Any other key combination is executed normally. Note that all Octave
+abbrevs start with a grave accent.
+
+@item M-LFD
+Break line at point and insert continuation marker and alignment
+(@code{octave-split-line}).
+
+@item M-TAB
+Perform completion on Octave symbol preceding point, comparing that
+symbol against Octave's reserved words and built-in variables
+(@code{octave-complete-symbol}).
+
+@item M-C-a
+Move backward to the beginning of a function
+(@code{octave-beginning-of-defun}).
+With prefix argument @var{N}, do it that many times if @var{N} is
+positive; otherwise, move forward to the @var{N}-th following beginning
+of a function.
+
+@item M-C-e
+Move forward to the end of a function (@code{octave-end-of-defun}).
+With prefix argument @var{N}, do it that many times if @var{N} is
+positive; otherwise, move back to the @var{N}-th preceding end of a
+function.
+
+@item M-C-h
+Puts point at beginning and mark at the end of the current Octave
+function, i.e., the one containing point or following point
+(@code{octave-mark-defun}).
+
+@item M-C-q
+Properly indents the Octave function which contains point
+(@code{octave-indent-defun}).
+
+@item M-;
+If there is no comment already on this line, create a code-level comment
+(started by two comment characters) if the line is empty, or an in-line
+comment (started by one comment character) otherwise
+(@code{octave-indent-for-comment}).
+Point is left after the start of the comment which is properly aligned.
+
+@item C-c ;
+Puts the comment character @samp{#} (more precisely, the string value of
+@code{octave-comment-start}) at the beginning of every line in the
+region (@code{octave-comment-region}). With just @kbd{C-u} prefix
+argument, uncomment each line in the region. A numeric prefix argument
+@var{N} means use @var{N} comment characters.
+
+@item C-c :
+Uncomments every line in the region (@code{octave-uncomment-region}).
+
+@item C-c C-p
+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
+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
+Move to the `real' beginning of the current 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
+Move to the `real' end of the current 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-n
+Move forward across one balanced begin-end block of Octave code
+(@code{octave-forward-block}). With numeric prefix argument @var{N},
+move forward across @var{n} such blocks (backward if @var{N} is
+negative).
+
+@item C-c M-C-p
+Move back across one balanced begin-end block of Octave code
+(@code{octave-backward-block}). With numeric prefix argument @var{N},
+move backward across @var{N} such blocks (forward if @var{N} is
+negative).
+
+@item C-c M-C-d
+Move forward down one begin-end block level of Octave code
+(@code{octave-down-block}). With numeric prefix argument, do it that
+many times; a negative argument means move backward, but still go down
+one level.
+
+@item C-c M-C-u
+Move backward out of one begin-end block level of Octave code
+(@code{octave-backward-up-block}). With numeric prefix argument, do it
+that many times; a negative argument means move forward, but still to a
+less deep spot.
+
+@item C-c M-C-h
+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 ]
+Close the current block on a separate line (@code{octave-close-block}).
+An error is signaled if no block to close is found.
+
+@item C-c C-f
+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}).
+
+@item C-c C-h
+Search the function, operator and variable indices of all info files
+with documentation for Octave for entries (@code{octave-help}). If used
+interactively, the entry is prompted for with completion. If multiple
+matches are found, one can cycle through them using the standard
+@samp{,} (@code{Info-index-next}) command of the Info reader.
+
+The variable @code{octave-help-files} is a list of files to search
+through and defaults to @qcode{'("octave")}. If there is also an Octave
+Local Guide with corresponding info file, say, @file{octave-LG}, you can
+have @code{octave-help} search both files by
+@lisp
+(setq octave-help-files '("octave" "octave-LG"))
+@end lisp
+@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 Barry

+@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.
+
+@table @code
+@item octave-auto-indent
+Non-@code{nil} means auto-indent the current line after a semicolon or
+space. Default is @code{nil}.
+
+@item octave-auto-newline
+Non-@code{nil} means auto-insert a newline and indent after semicolons
+are typed. The default value is @code{nil}.
+
+@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-continuation-string
+String used for Octave continuation lines.
+Normally @samp{\}.
+
+@item octave-font-lock-texinfo-comment
+Highlight texinfo comment blocks. The default value is @code{t}.
+
+@end table
+
+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}.
+@end itemize
+
+There is also rudimentary support for Imenu (currently, function names
+can be indexed).
+
+@cindex TAGS
+@cindex Emacs TAGS files
+@cindex @code{octave-tags}
+You can generate TAGS files for Emacs from Octave @file{.m} files using
+the shell script @code{octave-tags} that is installed alongside your copy of
+Octave.
+
+Customization of Octave mode can be performed by modification of the
+variable @code{octave-mode-hook}. If the value of this variable is
+non-@code{nil}, turning on Octave mode calls its value.
+
+If you discover a problem with Octave mode, you can conveniently send a
+bug report using @kbd{C-c C-b} (@code{octave-submit-bug-report}). This
+automatically sets up a mail buffer with version information already
+added. You just need to add a description of the problem, including a
+reproducible test case and send the message.
+
+@node Running Octave from Within Emacs
+@chapter Running Octave from Within Emacs
+
+The package @file{octave} 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. If Emacs does not know
+about this command, add the line
+@lisp
+(autoload 'run-octave "octave-inf" nil t)
+@end lisp
+@noindent
+to your @file{.emacs} file.
+
+This will start Octave in a special buffer the name of which is
+specified by the variable @code{inferior-octave-buffer} and defaults to
+@qcode{"*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
+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
+Send the current block to the inferior Octave process
+(@code{octave-send-block}).
+
+@item C-c C-i f
+Send the current function to the inferior Octave process
+(@code{octave-send-defun}).
+
+@item C-c C-i r
+Send the region to the inferior Octave process
+(@code{octave-send-region}).
+
+@item C-c C-i a
+Send the entire buffer to the inferior Octave process
+(@code{octave-send-buffer}).
+
+@item C-c C-i s
+Make sure that `inferior-octave-buffer' is displayed
+(@code{octave-show-process-buffer}).
+
+@item C-c C-i q
+Delete all windows that display the inferior Octave buffer
+(@code{octave-hide-process-buffer}).
+
+@item C-c C-i k
+Kill the inferior Octave process and its buffer
+(@code{octave-kill-process}).
+
+@item C-c C-l
+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-.
+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
+Display the documentation for function (@code{octave-help}).
+
+@item C-h a
+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.
+
+@table @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 table
+
+If you send code and there is no inferior Octave process yet, it will be
+started automatically.
+
+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 @qcode{'("-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}.
+
+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}.
+
+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
+@lisp
+(add-hook 'inferior-octave-mode-hook
+ (lambda ()
+ (turn-on-font-lock)
+ (define-key inferior-octave-mode-map [up]
+ 'comint-previous-input)
+ (define-key inferior-octave-mode-map [down]
+ 'comint-next-input)))
+@end lisp
+@noindent
+to your @file{.emacs} file. You could also swap the roles of @kbd{C-a}
+(@code{beginning-of-line}) and @code{C-c C-a} (@code{comint-bol}) using
+this hook.
+
+@quotation
+@strong{Note} that if you set your Octave prompts to something different
+from the defaults, make sure that @code{inferior-octave-prompt} matches
+them. Otherwise, @emph{nothing} will work, because Emacs will not know
+when Octave is waiting for input, or done sending output.
+@end quotation
+
+@node Index

+@bye
+
+@node Using the Emacs Info Reader for Octave
+@chapter Using the Emacs Info Reader for Octave
+
+You may also use the Emacs Info reader with Octave's @code{doc} function.
+
+If @file{gnuserv} is installed, add the lines
+@lisp
+(autoload 'octave-help "octave-hlp" nil t)
+(require 'gnuserv)
+(gnuserv-start)
+@end lisp
+@noindent
+to your @file{.emacs} file.
+
+You can use either `plain' Emacs Info or the function @code{octave-help}
+as your Octave info reader (for @samp{help -i}). In the former case,
+use @code{info_program ("info-emacs-info")}.
+The latter is perhaps more attractive because it allows to look up keys
+in the indices of @emph{several} info files related to Octave (provided
+that the Emacs variable @code{octave-help-files} is set correctly). In
+this case, use @code{info_program ("info-emacs-octave-help")}.
+
+If you use Octave from within Emacs, it is best to add these settings to
+your @file{~/.emacs-octave} startup file (or the file pointed to by the
+Emacs variable @code{inferior-octave-startup-file}).

Something's wrong here with the encoding. (I received the mail

Nitpicking: if possible, try not to change more than one line when all

Yuck! Please don't do that, it's ugly and non-standard. AFAICS, this
macro is used for two purposes:
. buffer name "*Inferior Octave*", for which the alternative would be
@file{*Inferior Octave*}, as we do with "*scratch*"
. a list of strings such as '("octave") or '("-q" "--traditional"),
for which we use @code{("octave")} (note that the convention is to
not place the quote ' before literal lists)
So please use our usual practices instead of this macro.

"LFD" is a key, not a string of 3 characters, so you should give it

^^^^^^^^^^^
It is useful to have cross-references for where the features you
mention are described, in this case abbrev-mode. This is so the
reader could consult those places if she doesn't have a clear idea of
what abbrev-mode is.
In addition, every function and variable from Octave mode that you
mention should have a corresponding @findex or @vindex entry before
the text that mentions it.

No need to capitalize N in @var. It will be automatically capitalized
in Info output, but in other formats will get the slant typeface.

Not sure why "real" is in quotes. If you wanted to emphasize it, use
@emph.

This suggests that perhaps "beginning of the physical line" is a
better term than "`real' beginning of the line".

If you use @vtable instead of @table @code, all the variables you

Anything after "@bye" will be ignored, so this last node will not be

Hello Eli,
thanks for your comments. I'm not very familiar with texinfo, yet.
So your comments were very helpful. I hope I have fixed all the issues.
I have removed some more obsolete parts as well. I have also updated
octave.el to reference the manual.
> Something's wrong here with the encoding. (I received the mail

I guess that's what I get for not sending the E-Mail from Emacs. It
seems to be an issue between my mail client, imap, and git. It seems
correct in the repo, so it should be correct when I push it.
> Anything after "@bye" will be ignored, so this last node will not be
> in the output. Is this what you meant?
Yes. The section is outdated. GNU Octave calls the info(1) program
which will fail in `comint-mode'. The section described how to work
around it by using the old `gnuserv' support and a shell script. I
have an updated version of that shell script. It basically emulates
info(1) by calling emacsclient with the proper flags. But I'm not
sure how and if it should be distributed within GNU Emacs and maybe if
emacsclient one day supports elisp defined arguments it could be done
completely from emacsclient. That's why I have commented out the
node. I have now added literal @c's to make it more clear.
Regards,
Rüdiger

+@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

+@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}.
+
+@node Running Octave from Within Emacs
+@chapter Running Octave from Within Emacs
+@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
+@findex octave-send-line
+@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
+Send the current block to the inferior Octave process
+(@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
+@lisp
+(add-hook 'inferior-octave-mode-hook
+ (lambda ()
+ (define-key inferior-octave-mode-map [up]
+ 'comint-previous-input)
+ (define-key inferior-octave-mode-map [down]
+ 'comint-next-input)))
+@end lisp
+@noindent
+to your @file{.emacs} or @file{init.el} file. You could also swap the
+roles of @kbd{C-a} (@code{beginning-of-line}) and @code{C-c C-a}
+(@code{comint-bol}) using this hook.
+
+@vindex inferior-octave-prompt
+@quotation
+@strong{Note} that if you set your Octave prompts to something different
+from the defaults, make sure that @code{inferior-octave-prompt} matches
+them. Otherwise, @emph{nothing} will work, because Emacs will not know
+when Octave is waiting for input, or done sending output.
