remiah:

I've been meaning to give ctags a try, so I took a quick look via google and found that it supports perl, so I'll have to give it a try in the morning. The page I found gives a sample invocation as something like this:

ctags -f tags --recurse --totals    \
      --exclude=blib --exclude='*~' \
      --languages=Perl --langmap=Perl:+.t

Update: Another thread here on perlmonks mentions a pltags.pl script that comes with vim, and a module by osfameron. I'll have to look into those as well.

When your only tool is a hammer, all problems look like your thumb.

thanks for reply. I didn't know I already have pltags.pl .
I thought I used to create symbolic links for recursive directrories, so I did it like this.

#make tags file
find ./ | xargs pltags.pl

#replace ./ with fullpath ...space character of [] is tab...
cat tags |
sed 's^[    ]\./^[  ]'`pwd`'/^' > .buff
mv .buff tags

#create symlink
find . -type d -exec ln -s `pwd`/tags {}/tags \;

But "Another thread" told me if I set tags=path/to/tagfile value on vim, this is completly needless. "Another thread" was also good for me because I forgot the key for jump Ctrl+], back Ctrl+T. It was very helpful for me.

"I am using vim with Freebsd, but any other method than vim are welcome if it enables me to jump higher."

I personally use lightweight IDE called geany on a linux desktop. This small IDE knows about perl syntax and jumps into other files _{(with function definition)} within the project by a simple keystroke.

Also for emacs there is etags, I used to use it before.

If you intend to use it only with perl, I suggest to look closely at PADRE.

I tried PADRE. It took long time to compile but lighter than I thought. IDE with debugger is fascinating for me. For jumping through facilities it seems the same mechanism with ctags. Suppose you are editing BBB/Bar.pm and wonder what is function aaa?

#AAA/Some.pm 
package some; sub aaa{}; 1; 
#BBB/Foo.pm
package foo; sub aaa{} ; 1;
#BBB/Bar.pm
package bar; 
 use base qw(foo);
 sub bbb{
   aaa();
  }
1;

ctags generate sorted list for aaa like this.

aaa AAA/Some.pm
aaa BBB/Bar.pm

If class hierarchy took considered, they must jump to BBB/Bar.pm's function aaa, but Padre and ctags jump to AAA/Some.pm's function aaa. I guess they use same logic and jump to first line of sorted list.

Just type g+Ctrl+] show me list of functions in ctags and vim. It is enough good to me so far. In reality, we have factory class? or something, so, much or less I have to jump with my legs.
