Hi,
    I don not know where to ask my questions.
So please regret me for asking some easy questions, which I really do not know.


In emacs source code:
1. Where is the definition of DEFSYM, I can not find it in lisp.h now.
2. Where is the definition of the struct emacs_globals, I can not find it in all the source .c .h files 
    in emacs-master source code which I get from github.
3. Can you give me some advice for reading the emacs source code ?


Can anyone help me, a newbie emacser. Sorry for disturbing  you and thanks a lot! 


BR,
 Miracle

Don't worry, asking questions is how you learn. :)

`M-x describe-function RET defsym RET` tells me it doesn't exist at
all for me, so probably not at all for anyone.

`emacs_globals` is mentioned at:

- line 116 of src/alloc.c
- line 3, and 1009 of src/globals.h

Well, learning C and LISP is a good start, and learning to use `grep`
(I assume you're on Linux or a platform like it) is great for finding things.

This is the right place for this type of questions.

From my checkout of `master' branch:

src/lisp.h:1796:9:#define DEFSYM(sym, name) /* empty */

> 3. Can you give me some advice for reading the emacs source code ?

There is a lot of difference among the C part and the Lisp part. Even on
the C part there are areas of varying difficulty (the redisplay engine
is famous for its complexity.) IMHO best thing to do is to start by
becoming proficient with Emacs Lisp (use the Emacs Lisp info pages) and
then focus on a specific set of features and start fixing bugs on it.

The only thing that comes to my mind is to debug your .emacs file, since
I can't see anything binding the "C" key. To do that, first start emacs
with the -Q option in order to make sure that the error lies in your
personal configuration. Then, restart emacs deleting every time
different parts of the .emacs file until you find which one triggers
that behaviour.

Sorry, I think I don't understand the problem. When you write "C" here,
you mean the Control key? And once you press it, Emacs shows C- in the
"command line" (I guess this is the minibuffer, at the bottom of the
window, right?)

> Please give me a hand.

Try starting Emacs like so:

  emacs -Q

and see if the problem is still there. If it disappears, then the
problem may be coming from your .emacs.

please give detail. What exactly is the mode? and what exactly you
mean by macro? What do you mean by emacs window stuck? For how long?
Also, OS and emacs version.

you need to be specific and give concrete detail.

one thing of note is that emacs doesn't support thread. Practically
this means that most things you do in emacs, emacs needs to finish
that first. This is especially noticable when do do network related
things like ftp. Don't know what is your macro. But if that is
computationally intensive, few sec wait is prob right.

Dear All,

Let me introduce myself, I am VLSI engineer and I am fan of emacs and use it extensively for editing my code.

However, sometimes when I use emacs auto completion macros (i use verilog specific macros), emacs window gets stuck and after some time it regains. Can you please help in hunting out the reason for same.

Can somebody let me know what all functionality in such editors loads processor mostly and makes its slow? Is it LISP programming (used to code emacs) is reason or lots of functionality is one?

I will be very grateful if some body from community help me out with this.

Thanks in advance for your time and response.

Dhaval
