Related to a recent question, is there a way to bookmark a spot in a
long text?

My makeshift method right now is to create a temporary subheader at
the position and then tag it, but I would like to implement tags much
like the Emacs "mark" is often implemented temporarily. Jumping to
precisely the cursor position where I was last reading.

Bookmarks are excellent for persistence.  However, if you want
robustness to filling and sorting, then implementing ID markers might
be a good way to solve it.

Strict answer: Built in functions are in source code. If you installed
emacs from apt (apt-get/synaptic etc) you probably dont and cant get
those.  If you want it compile emacs by hand which is not very hard on
linux.

A more helpful answer would be that if

then you would be better off doing:

while (fairly new to computers and emacs) do
  use emacs
  read elisp

I guess there is a confusion because the word "builtin" has two
closely related but different meanings.

Narrow meaning: "builtin" means built into the C core -- ie written in
C.
You will see this usage if you ask help on the function car or +

The looser broader meaning is: anything that comes with emacs.

If the OP meant the looser meaning then emacs23-el should (mostly)
suffice
If the narrower then he will probably need to compile emacs for
himself.
In any case etags-tagging is not necessary and if you do it it will be
a big pain to interface it with the emacs describe-fucntion etc help
system

If you want to browse emacs lisp sources, you don't need to create
tags. You can get to the definition of a command by typing
C-h f RET  then enter the name of the command.
You then get a summary of the command in a window.
Now clicking on the underlined filename on the upper right of the window
will bring you to the source.

To save space an installation of GNU Emacs can be done by only  
installing the ELC files. If you want to see the EL files, i.e., it's  
not enough for you what C-h f <function name> RET returns, then get  
the GNU Emacs source code. Which is now at #23.2.

Also, it might work to post this same question to an ubuntu list asking for what to install to get the source.

In case you didn't get the gist of the previous replies, there are two kinds of source: elisp and c.  With a nice full install (like my Mac has), I can do C-h <function> to get the built in help.  And then I'll have a link at the top that will take me to the source no matter whether it is in lisp or C.  Very very nice to have.

Good luck.

Some Linux distributions offer to install the *source* packages as well.

Hi all, after a bit of searching...the emacs .el files are available
through the ubuntu/emacs ppa. In case anyone is as ignorant as I am (I
am assuming this is archived) the files are compressed and need to be
extracted BEFORE you can create a functioning tags table.

Did you install emacs23-el? http://packages.ubuntu.com/maverick/emacs23-el
And you did you wont need ppa... etags
If you did and you dont get the el files still you probably have a
ubuntu packaging bug

Please let me know  -- What are all the emacs-related packages you
have installed?
ppa.. will give you unnecessary dependency-hell at a later point

If emacs is setup correctly the el files can stay compressed and emacs
will unzip before open-ing then.

Yes its easy to get C sources in ubuntu/debian etc but is that source
package linked with the emacs binary?  ie does help on a builtin C
function take you straight there? I would be surprised if yes.
elisp sources are much easier and you should get them in package
emacs23-el elisp-manual (at least thats what it is on debian)

Re: TAGS

[simon cossar]

Thank you for your replies, I was looking everywhere for the elisp
source code - it's good to know it isn't there. I learned a lot about my
file system in the process. It would be great to see the .el files, as
I'm finding emacs lisp combined with the C-h f function surprisingly
easy to read. 
Thanks again,
Simon

The OP uses ubuntu, which provides lisp source code in specific packages
(with names ending in -el).

depends on the Shell and number of files you're using in zsh e.g you
can just get away with
etags **/*.{c,cc,h} but if there are too many files the command line
will get overflowed.

The other thing which works 

find . -name "*.{c,cc,h}" -exec etags -a -o SOME-TAGS-FILE {} \;

which will call etags on any file and append that stuff to
SOME_TAGS-FILE, well minor errors I may have introduced ;-)

Hi all:



How to generate TAGS file in a complex directory structure (with many subdirectories)? 

I use  find . -name "*.[cch]" -print | etags - to generate TAGS file for all *.cc and *.h files. Are there any other methods?

By the way, when I use M-x tags-search to search a word, e.g., pointer_a, how to make it case-sensitive and match-word-only, so that

POINTER_A and pointer_a_1 will be skipped?



Thanks a lot.



Jack

   find . -name 'whatever' | etags -

This is fine, but for one problem: "*.[cch]" will _not_ find *.cc
files, since the "[]" group stands for a single character.  So better
use something like

    find . -name "*.[ch]" -o -name "*.cc" | etags -

What's wrong with this one?

Did you try to set tags-case-fold-search?
