global -u : update tags

[Richard Riley-6]

I am trying to use glbal with emacs and to tage .el,.js and .php.

I have three queries and one suggestion.

Q1) Why does global -u ignore gtags.files? i.e

find . -iname "*.el" > gtags.files
gtags -f gtags.files

*fine*

but ..

then in an emacs save hook I call "global -u" and it takes about 30
seconds as it tags ALL files under my cwd. Why is "update" not
respecting the files already tagged?

Q2) can one only *include* certain wildcard patters via the .globalrc?
(The skip option needs documenting with working examples too : but a
working "only include" is far more useful - I think for sure there is an
option but I dont see it.)

Q3) Global claims to support php, but it wont locate variable
declarations. Is this for a reason or a bug?


Suggestion: gtags-find-tag should default to

    (setq tagname (region-or-word-at-point))

as tags can and do include "-" for examples.

I am new to gtags/global so sorry if any of this is blindingly obvious.

(as an emacs user I would also like to be able to specify directory
specify global config files : possible?)

^^^^^ This is the most important one.

Why does global -u not do an incremental tags? I gave an example in my
first post.

Is this understandable?

The main problem is that "global -u" does NOT do an incremental update
for files already tagged using gtags -f gatgs-files. It tags ALL files
in that directory.

The problem is, for example, that I keep certain gnus files in my
.emacs.d. I generate a small GTAGS using "gtags -f gtags.files" BUT when
I save a .el file the onsave for emacs-lisp calls "global -u" which tags
ALL files in .emacs.d. Is this clearer?

How do I tell global only to tag *.el and *.org for example from the config file?

The emacs extensions doesnt allow selection of a $phpvariable. Have you
tried it? I am talking from within emacs.

The most important is part 1)

It does.

Just do what I did on the command line.

Once more :

gtags -f gtags.files

ls -l G*

global -i

ls -l G*

HUGE!

Sorry but I cannot understand what you are saying.
Would you please explain it for example?

The current parser doesn't consider declarations of variables to be

Did you try it?

Go to a directory with MANY files in. Create a gtags.files with only a
few file names in. Then

gtags -f gtags.files

ls -l G*

*look at the tags files size*

Now,

global -u

NOW look at the tags file sizes

I dont know if its a bug. I dont understand the documentation. I am
asking how to configure global to ONLY update for the files already
tagged or, and better,  how can I specify in the .globalrc only to tag REAL source
files? Currently it is tagging every file in the directrory.

So it does use the gtags.files? Or?

And once again you have snipped my Q. This makes it very difficult as I
dont know if you have a different config.

Does this Q make sense to you :

Would you please confirm the file name is 'gtags.files'?
If it is correct, would you please do it without emacs?
If it brings the same problem, it may be a bug.

You can do it using the langmap. Please see the online manual.
The langmap has the same format as the one of Exuberant Ctags.

I try to rephrase  this.

How do I configure a project directory so that gtags only tags certain
files (currently I use gtags -f gtags.files) and then "global -u" ONLY
updates those tagged files. Currently "global -u" currently tags ALL
files. You can easily reproduce this on the command line assuming no
other global config files.

I am currently using debian squeeze.

Could you possibly explain to me how I configure global/gtags to only
tag certain file types using .globalrc. Otherwise if I use gtags.files
then *new* files wont be tagged correctly.

Debian?
Would you please use the latest version of GLOBAL?
You might be using an old verion of GLOBAL that doesn't recognize
'gtags.files'.

or possibly point me to the place in the manual which explains
which *types* of files get tagged? I really dont want to install a new
global if not necessary and feel sure there must be a simple way to
specify in the .globalrc which file types are tagged. I thought maybe
"suffixes" but that's been deprecated apparently : I'm surely missing
something obvious.

Which version of GLOBAL are you using?
The following command will show it.

global --version

The one in debian squeeze (stable).

5.7.1

but as I say, all I want to do is configure the type of files tagged by
global - something I assume is possible even on an older global?

If its not possible to tell global to only tag certain file types, then
of course I can look into moving to a new version but would prefer not
to if avoidable - but I suspect it is possible and I am missing
something in the manual since it seems such a basic configuration
requirement for any tagging system.

Many thanks for your support

r.

It is a version three years ago. It cannot understand 'gtags.files'.
It seems that you are reading the manual of a different version.

If I could just bump this : I cant find any answer than "langmap" and
that doesnt seem to work for me. I am using the default langmap and that
says

        :langmap=c\:.c.h,yacc\:.y,asm\:.s.S,java\:.java,cpp\:.c++.cc.cpp.cxx.hxx.hpp.C.H,php\:.php.php3.phtml:

so why when I save an .el file in my .emacs.d why is global -u taking 3
minutes?

This is with the debian stable global and the latest compiled from
source.

I dont want to use gtags.files as the new files wont be tagged.

It seems a very common requirement to only update tags using files of a
certain type - in this case .el files- and to my shame I cant seem to
make it work. Surely an example is possible?
