Hello,
I have bugs with indentation of php files. I use php-mode and
sometimes instead of proposing to complete a name a of function or of
a variable there is the message: Indenting region... done.
A way of making it bug at all times is to do TAB when I search
something in the page thanks to ctrl+s, if not just having a lot of
php fils opened make emacs indenting fails.
So what can I do to relaunch indenting mode, the only way I have found
to use indenting when it has bugged is to restart emacs, that's
annoying...
I am under Mac OS X 10.6 with Emacs 22.3 and in my ~/emacs/.emacs fil
I have:
---
(set-foreground-color "wheat")
(set-background-color "DarkSlateGray")
(set-cursor-color "white")
(global-set-key [(tab)] 'smart-
tab)
(defun smart-tab ()
"This smart tab is minibuffer compliant: it acts as usual in the
minibuffer. Else, if mark is active, indents region. Else if point is
at the end of a symbol, expands it. Else indents the current
line." (interactive) (if
(minibufferp)
(unless (minibuffer-
complete)
(dabbrev-expand
nil))
(if mark-
active
(indent-region (region-
beginning)
(region-
end))
(if (looking-at "\
\_>")
(dabbrev-expand
nil)
(indent-for-tab-command)))))
---
Thanks,
Vincent.

I'm not sure I understood, anyway:
- indenting with TAB is I think default in many modes, if you have
selected some text
- why would you press TAB while you search with CTRL-s?

ok, sorry but I am not fluent in english and I understood just now
what's not working:
I use tab to expand and to indent the code.
The .emacs file you can see above makes me do both by typing tab but
sometimes there is a bug and it's impossible to use tab to expand,
instead of expanding the name of a function I am writing, it will
write "Indenting region... done".
I looked for many way to use tab to expand, for example I tried to
understand this page:
http://emacsblog.org/2007/03/12/tab-completion-everywhere/
but with no success. :-(
I am under Mac OS X and I don't know how to expand, that's why I am
looking for a way to use tab to increment (by default) and to expand
as well...
How could I set a keyboard short cut to expand instead of trying to
find a way to use tab for doing both ?
Thanks,
Vincent.

Normally, `M-TAB' (hence `ESC TAB') will complete text (e.g. a function name) at
point. It is bound by default to `complete-symbol', `lisp-complete-symbol',
`completion-at-point', or something similar, depending on the current mode and
your Emacs version.

Isn't that a very inconvenient default? Almost every window manager
across platforms intercept that to switch windows...

1. don't talk about a bug, it's just the behaviour you're setting..
2. I suggest you to use auto complete instead, see here
http://www.emacswiki.org/emacs/AutoComplete
3. of course you can disable the indention I guess and only try to
complete, but I think indention with tab is also very nice..

Yes, some of us think that it is. Note hoever that it is "Meta-Tab",
not "Alt-Tab".
Personally I use the left window key (instead of Alt) as Emacs' Meta.
On ms windows that requires the patched version of Emacs+EmacsW32
however.

Thanks Lennart, this subtlety had escaped me. :-p
However I found the windows key is often not recognized properly when
using emacs in no-window mode, specially in some terminal emulator. A
remapping like that could be very inconvenient. Anyway, thanks to Drew I
heard about the feature, on my own I never would have found it. (I found
most of the "fancier" commands through typos ;) )

No, they do not intercept `ESC TAB'.
Some, such as Windows, do, by default, intercept ALT-TAB, which maps to `M-TAB'
by default (that's two "by default"s ;-)).
But you need only do this to make Windows pass `M-TAB' along to Emacs:
;; (setq w32-alt-is-meta t)
(when (fboundp 'w32-register-hot-key)
(w32-register-hot-key [M-tab]))
The first line is not really needed - t is the default value.
Variable `w32-alt-is-meta' determines whether ALT maps to Meta.
The other lines tell Windows to pass `M-TAB' to Emacs.
If ALT maps to Meta, you can register [M-tab] as a hot key.
If it does not, you can register [A-tab] as the hot key.
> Yes, some of us think that it is. Note hoever that it is "Meta-Tab",

Yes and no. It is `M-TAB' in its incarnation as ALT-TAB.
It is not `M-TAB' in its incarnation as `ESC TAB'. ;-)
Kidding aside, It's useful for users to know that they can use ESC instead of
ALT to realize Meta key sequences. Oldsters know this, because Emacs Meta
predates Meta as ALT key (AFAIK). In older versions of Emacs, Meta key bindings
are even listed as bindings on the ESC keymap.
And it is useful to know that it is the ALT key that Windows grabs by default
(e.g. ALT-TAB); it is not necessarily the Meta key - as you indicate yourself,
Lennart, in what you say next:
> Personally I use the left window key (instead of Alt) as Emacs' Meta.
In sum:
1. You can use ESC instead of the Alt key, even if Windows grabs ALT-TAB.
2. If you want, you can tell Windows not to grab ALT-TAB but to pass it along to
Emacs.
(3. If you want, Emacs will fix you a delicious bouillabaisse for supper...)

But if you use a vi emulator in Emacs like Viper (which many uses)
then you can not use ESC TAB since ESC is caught by the vi emulator.

And this does not always work (as I have told many, many times). To
make it work correctly you need the patched version of Emacs+EmacsW32
(and then the recipe is a bit different).

Hey, if something else steals ESC, then sure, it's not available for this. That
goes without saying.
But with the normal ESC map, this is not a problem.
We're not, here, going to list every possible Emacs library that might modify
the ESC map are we?
If you bind `C-h f' to `forward-char', then it won't do `describe-function'
anymore. But that's not a reason not to inform help-gnu-emacs readers that `C-h
f' is normally `describe-function'. Same thing here.

Yes, you've said that many, many times. But never (AFAIK) with any explanation
or demonstration. You've hinted that there might be some corner cases that are
problematic, but I've never heard anything more concrete.
What can I say? It's always worked for me. No doubt I just haven't run into
those corner cases.
I don't doubt that you are speaking the truth when you say you've run into a
problem, but if you aren't more specific than that, then saying that is not very
helpful.
Unless you provide some helpful info about it, this is like Chicken Little
screaming "The sky is falling!". That might scare some people away from trying
it, when trying it might actually be useful for them.
I understand that from your perspective this is a problem and Emacs+EmacsW32 is
the solution. But I've never experienced the problem, and AFAIK you have never
explained the problem.
How about a simple recipe starting with `emacs -Q' in unpatched, vanilla Emacs,
to demonstrate the problem? Then users can decide if it's something they need to
worry about.

Hello there,
Actually I have this problem really often and I have to find a
solution better than by closing a file and reopening it. I have
functions in my code with long names looking like this:
JS_dis_create_Account() so, I do need the completion to work, that's
so much useful...
I use ALT+tab to complete functions names, but after a while instead
of completing it writes "Indenting region...done", and if I go in
another buffer, and try ALT-tab it will complete my function name.
Maybe I should try to set another shortcut for completion. How do I
set for exemple CTRL-f for completion instead of having CTRL-f to go
to the next character.
Thanks,
Vincent.
