I suppose you mean C tags. For them to work, the tags file must have
been created (preferably by Exuberant ctags) and Vim must be able to
find it.
By default, Vim looks for the tags file in the current directory (which
will be shown in answer to the :pwd command) and in the directory of the
current file. If you want to search other locations (such as the parent
directories of the current file's directory) you will have to tweak the
'tags' option yourself.
Note also that if your coworker has 'autochdir' set (which I don't
recommend) the current directory will always be changed to the directory
of the current file, which means that only one of the two "typical"
locations of the tags file will be searched.
With only an EXINIT environment variable, there are many nice features
of Vim which you won't see. In particular, it will put you in
'compatible' mode, some plugins will simply not work, and with the
values you have set, you won't even get filetype-specific behaviour. I
recommend to remove that EXINIT variable and to write the following into
a file named ~/.vimrc
runtime vimrc_example.vim
set autoindent
set ignorecase showmatch
set magic
set shiftwidth=4
If later you want more customizations, you will add them to this file,
usually after the call to vimrc_example.vim (but if you want to change
the menu and messages language, you must do it before instead). For
instance, to be able to edit files containing any kind of weird
characters you might add
if has('multi_byte')
" if the required capabilities are not available,
" we cannot use them
" is the OS locale already Unicode?
" if not, prepare to change
if &encoding !~? '^u'
" but first, avoid jamming keyboard input
if &termencoding == ""
let &termencoding = &encoding
endif
set encoding=utf-8
endif
" set a «reasonable» heuristic to determine
" the 'fileencoding of existing files
set fileencodings=ucs-bom,utf-8,default,latin1
" the following two settings are optional
" create new files in UTF-8
setglobal fileencoding=utf-8
" create new Unicode files with Byte-Order mark
setglobal bomb
" Note: certain files, including anything starting #!
" must have 'nobomb' instead (using :setlocal),
" or be created in some non-Unicode 'fileencoding'
" such as e.g. Latin1.
endif
or to use a font of your choice in gvim (the GUI version of Vim) you
would add something like what is shown under :help setting-guifont
Best regards,
Tony.
