How to find all occurrences of a variable in Vim? -

-

in vim, how find occurrences of variable in files under directory?

i know vimgrep works sometimes, looks text , doesn't work if other classes have variables of same name , want variable under specific class.

what should do? or should ide instead?

why want use ide when have one? vim is ide configurable , usable different languages..

you use cscope build database of code. database

  • allows searching code for:
    • all references symbol
    • global definitions
    • functions called function
    • functions calling function
    • text string
    • regular expression pattern
    • a file
    • files including file

further features of cscope:

  • curses based (text screen)
  • an information database generated faster searches , later reference
  • the fuzzy parser supports c, flexible enough useful c++ , java, , use generalized 'grep database' (use browse large text documents!)
  • has command line mode inclusion in scripts or backend gui/frontend
  • runs on flavors of unix, plus monopoly-controlled operating systems.

once database created, browse through usages of variables, functions, etc.

edit (slightly ot):
cool thing that's quite handy when working vim on code taglist plugin uses ctags:

the "tag list" plugin source code browser plugin vim , provides overview of structure of source code files , allows efficiently browse through source code files different programming languages.
