Emacs and C++ codesense

Emacs and C++ codesense

[spamfilteraccount]

I'm looking for solutions for working with C++ code in Emacs.

I'd like the following:

- Jumping to the definition of the symbol I'm standing on when I press
a key. I know tags is useful for that, but they don''t seem to work
properly in every case, only in most of the cases and I'd like a
proper solution.

- Show the documentation of the current symbol in a tooltip when
pressing a key. The tooltip is not a big deal. I can do it if I can
get the documentation somehow.

- Inteligent completion of the current symbol when I press a key.

I don't want ECB, because I don't want separate windows within the
frame showing information. I like to work in a single frame and get
information only if I press a key explicitly.

I suspect semantic can do some or all of the above. Is it true? Is
there a solution out of the box which works like described above or I
have to learn how the semantic api works and implement my own
solution? How good is semantic's C++ parsing/support?

Are there other alternatives?

xref seems nice, but I'd like to evaluate free software first.

I'm also checking out kdevelop which I hear has good support for C++,
but I really don't want to leave emacs (iswitchb!) if I can find a
satisfactory solution.

Thanks.

Tags work for me; if they don't for you, please give an example.

There's also Ebrowse, which is more C++-aware.

Try "C-h S".

Is "M-/" intelligent enough for you?  If not, please define
``intelligent''.

I think you'll have to stick with tags, just make sure you use
exuberant-ctags, it has much more fancy support for things. A solution
based on semantic is possible, but not available as of yet.

See semantic-idle-completion-mode, semantic-ia-show-doc, although that
depends on how much info you want. You do get the prototype though.

That's good, since ECB doesn't concern itself with completion :).

Semantic should fit the bill. There's semantic-ia-complete-symbol[-menu],
and also semantic-hover-completion.el, which I'm going to post in a
minute. I'm not exactly sure how much stress the C++ support can stand, as
I don't code C++, but basic testing says it works pretty well.

cscope is the best for this IMO. Well, it is for C .....

yes. ECB is a bit in your face I agree.

I used hippy-expand for the expansion! No tooltips, but cscope worked
for me. I never used it for c++, but I believe it works ok.

No insult intended - but it takes a lot of configuring and learning to
get familiar with it. Even the very first design issue you hit - why
doesn't "switch to other buffer" include the ecb windows? After a while I
appreciated this touch. But not when I started :-; I find that the
overhead of the ascii character window splits takes too much real estate
from the editor - yes I know you can expand it .... Also, I never got
speedbar working properly with it.

In fact, I intend to be trying ecb out again soon - it will be
interesting to see how well the issues with winman integration are now.

It is still confusing, btw, on what ecb to use. The "best" way seems to
be from cedet, but cedet seems to be ancient. Could you maybe post a
"how to get up and running" update so someone can get the latest all
working and integrated in a few easy steps?

Huh? What do you mean? Go to ECB's website, everything is described there
in great detail. And there's no ECB included in CEDET, rather it's a
dependency of ECB.

Apologies. I was on crack when I posted that. I was referring more to
the links between the two. Or meant to. In addition my comments about
ecb were unfair as I was or meant to refer to the confusion with cedet
version more than ecb.

Actually, the whole bunch of cedet/winring/ecb does confuse me. I never
quite got the hang or the point of semantic either..... yes, I know its part of
cedet....

CEDET, as the name suggests, is a collection of various tools, connected
mostly by the fact they're developed together, and some depend on the
others. Semantic is the most prominent part of CEDET, which gives the
access to a complete language parser infrastructure, and subsequently to
its output, allowing for construction of language-sensitive tools (for
example, ones that know what variables are visible at any given point in
the source) without tying them to any particular language.

ECB is a collection of tools supposed to give better code browsing (hence
the name) tools, as opposed to the ones aimed at writing code.

Winring is not tied or related at all to either of the two, just that ECB
has explicit support for it because it does some heavy windows-management
magic.

Yes - I read that. I just don't see how its useful in C development. I'm
not saying it is not useful. Just that I don't see what its for. Mea
culpa. The code navigation doesn't seem to do much and the decoration
modes are not particularly helpful. I guess it could do with some sort
of tutorial as I played with it a while and didn't really see what
benefits it gave. Maybe you could describe how you use it?

Yes, I used it for a while but found the locals/files stuff to be of
limited use.

I realise that, but its kind of a must have when switching between
things like ecb and gnus IMO.

Notice how it very clearly has an idea what's going on in the C code and
reacts to that.

Locals are really useful for getting an overview what's there in the file,
and for jumps. Files stuff I don't use too much indeed.

Not using Gnus, and even if, I use separate frames for clearly separate
layouts. So far I didn't feel the need to optimise layout management
enough to take the time to evaluate and choose one of the window managers.

Not in any organised manner, no. It's just a demonstration of some simple
(more or less) functions of several packages I use, amongst them semantic
and related tools. The tooltip completion you can see I posted not so long
ago to emacs-sources, it's called semantic-hover-completion.el. Version
0.1 is very buggy, though, so it's not really very usable for anyone who
isn't me. Unfortunately, I won't have the time to fix that in the
immediate feature.

ok, so it wasn't a demo of what semantic can do. It was a mish mash of
different things not likely to be reproduced by anyone but yourself :-;

Why did you do your own completion? What was wrong with intellisense?
Have you used intellisense?

But of course, large parts of it were due to semantic usage. You asked how
it can fit C coding, this is my answer.

Uhh, this *is* intellisense. At least as long as you regard "intellisense"
as a generic description and not trademarked name by MSFT. I wrote it
because the existing completion popups for semantic were not close enonugh
to the original IntelliSense, or rather, diverged in ways that seriously
hindered their usefulness.

But which bits? I have no idea which bits were semantic and which others
were part of your "mish mash of other packages".

Well, when you say your wrote your own completion package, how is one
supposed to know the difference?

I turn the pop ups off and use tab cycle completion - works quite
nicely.

But again, could U request some sort of explanation of the demo gif?
Just looking at it tells me nothing whatsoever about how you used
semantic to do a job of work.

Semantic shines through whenever you can see emacs visibly having an idea
about the code's meaning. In this demo, it means 1) the suggestion popus
2) the second time I use `fwritex' template, in which FILE *STREAM formal
parameter is replaced by a choice of all currently visible variables of
type FILE*

"intellisense" is either 1) IntelliSense, a trademarked name for MSVS
context-sensitive completion, in which case none of the above is
intellisense 2) a generic name for a class of similarly-working packages,
in which case both are implementations of intellisense. If you want to
know the difference, download the package and read the description

Not really, I don't have the time for that now. I intend to turn it into a
properly integrated and easy to install and setup package, but it hasn't
happened yet.

Why would I be talking about Intellisense from MS? What sense would that
make when discussing semantic in an emacs NG?

Are really do not know why you appear to be so determined to make this
difficult. Do you really think I mean anything other than the
Intellisense which is part of the semantic package? And is called
"Intellisense" by cedet package itself? Here:

http://cedet.sourceforge.net/intellisense.shtml

Cheers.

Basically all you have said is "look at this gif which is made by a
mash of packages only I know about". How that is supposed to help in any
way understand semantic is beyond me. It does look impressive though and
my basic frustration is simply being unable to get it (semantic) to work
anything like you have demonstrated :-(

I used Emacs' etags first. Moving to exuberant ctags solved the
problem.

describe-syntax? Are you sure you meant that?

I was thinking of something like this:

  instance.<pressing completion key>

Only those completions should be offered which make sense in the scope
of the object (data members, member functions, inherited member
functions, etc.)

You didn't say which Emacs version you had, so I guessed, and my guess
was wrong.  I now think you use v21.x, where the command I meant is
bound to C-h TAB.

If that is what you want, why not download esense and use it?

I think you want "C-c C-m TAB" in ebrowse.el.  Read all about that in
the Ebrowse manual (which comes with Emacs).

Because it's for Erlang which is not exactly related to C++.

What does C-h TAB do? Can you please describe the function names as key
bindings change.

What has erlang got to do with C++?

Again - please list function names. It really would help.

The function is info-lookup-symbol.

It's ebrowse-tags-complete-symbol.

But please note that by insisting on function names like that you
abuse the help I give here to some extent.  The bindings I mentioned
are the default bindings, not my personal bindings.  Even though key
bindings may be different in your setup, you can always fire up
"emacs -q --no-site-file" to see what are the default bindings.  And
in the last case, where you need to load a library to have the
command, I named that library, and even pointed to the appropriate
manual.  It is not nice to require that I also write the function
names explicitly, as the information I gave originally already
provides you everything you need to find those commands by yourself.
This is not a hot help line, and you are not paying me for my time,
you know.  Please be ready to invest some of your own time and some
minimal effort into digesting the help you are given.

What is "M-/"? Not all setups have the same key bindings.

M-/ is the default binding of dabbrev-expand.
