I have just installed Ctags (to help with C++ development) with my Vim (or rather gVim), and would like to find out your favorite commands, macros, shortcuts, tips that go along with it...
Share your best arsenal. What other Vim add-ons you would recommend for C++ on Vim development?
EDIT What other add-on you would use in conjunction with Ctags?
EDIT2 What version of gVim you use with tags? Does it make a difference?
EDIT3 How do you enhance your programming experience for both big and small projects?
回答1:
Ctrl+] - go to definition
Ctrl+T - Jump back from the definition.
Ctrl+W Ctrl+] - Open the definition in a horizontal split
Add these lines in vimrc
map :tab split:exec("tag ".expand(""))
map :vsp :exec("tag ".expand(""))
Ctrl+\ - Open the definition in a new tab
Alt+] - Open the definition in a vertical split
After the tags are generated. You can use the following keys to tag into and tag out of functions:
Ctrl+Left MouseClick - Go to definition
Ctrl+Right MouseClick - Jump back from definition
回答2:
One line that always goes in my .vimrc:
set tags=./tags;/
This will look in the current directory for "tags", and work up the tree towards root until one is found. IOW, you can be anywhere in your source tree instead of just the root of it.

Another useful plugin for C development is cscope Just as Ctags lets you jump to definitions, Cscope jumps to the calling functions.
If you have cscope in your ~/bin/ directory, add the following to your .vimrc and use g^] to go to the calling function (see :help cscope).
if has("cscope") set csprg=~/bin/cscope set csto=0 set cst set nocsverb " add any database in current directory if filereadable("cscope.out") cs add cscope.out " else add database pointed to by environment elseif $CSCOPE_DB != "" cs add $CSCOPE_DB endif endif
Almost forgot... Just as ctags - you have to generate (and periodically update) the database. I use the following script
select_files > cscope.files ctags -L cscope.files ctags -e -L cscope.files cscope -ub -i cscope.files
Where 'select_files' is another script that extracts the list of C and header files from the Makefile. This way I index only the files actually used by the project.
回答4:
You can add directories to your ctags lookup. For example, I have a ctags index built for Qt4, and have this in my .vimrc:
set tags+=/usr/local/share/ctags/qt4
回答5:
All of the above and...
code_complete : function parameter complete, code snippets, and much more.
taglist.vim : Source code browser (supports C/C++, java, perl, python, tcl, sql, php, etc)
回答6:
I use ALT-left and ALT-right to pop/push from/to the tag stack.
" Alt-right/left to navigate forward/backward in the tags stack map map
If you use hjkl for movement you can map
回答7:
Several definitions of the same name
g open the definition in a split, but also do :tjump which either goes to the definition or, if there are several definitions, presents you with a list of definitions to choose from.
回答8:
The command I am using most is C-] which jumps to the definition of the function under the cursor. You can use it more often to follow more calls. After that, C-o will bring you back one level, C-i goes deeper again.
回答9:
I've found the taglist plug-in a must-have. It lists all tags that it knows about (files that you have opened) in a seperate window and makes it very easy to navigate larger files.
I use it mostly for Python development, but it can only be better for C/C++.
回答10:
I've encapsulated tags manipulation in an experimental plugin of mine.
Regarding C++ development in vim, I've already answered there: I use my own suite, and a few other plugins.
回答11:
I've been adapting my vim plugins for two years to support big enough c++ project. You can take a look at them.
They use ctags and cscsope.

I put the following in my .gvimrc file, which searches up the tree from any point for a tags file when gvim starts:
function SetTags() let curdir = getcwd() while !filereadable("tags") && getcwd() != "/" cd .. endwhile if filereadable("tags") execute "set tags=" . getcwd() . "/tags" endif execute "cd " . curdir endfunction call SetTags()
I then periodically regenerate a tags file at the top of my source tree with a script that looks like:
#!/bin/bash find . -regex ".*\.\(c\|h\|hpp\|cc\|cpp\)" -print | ctags --totals --recurse --extra="+qf" --fields="+i" -L -
回答13:
I use vim in macos, and the original ctags doesn't work well, so I download newest and configure make make install it. I install ctgas in /usr/local/bin/ctags(to keep original one)
"taglist let Tlist_Ctags_Cmd = "/usr/local/bin/ctags" let Tlist_WinWidth = 50 map ta :TlistToggle map bta :!/usr/local/bin/ctags -R . set tags=tags;/ map map
回答14:
I adapted the SetTags() search function above (which should be replaced by the equivalent set tags+=./tags;/) to work for cscope. Seems to work!
"cscope file-searching alternative function SetCscope() let curdir = getcwd() while !filereadable("cscope.out") && getcwd() != "/" cd .. endwhile if filereadable("cscope.out") execute "cs add " . getcwd() . "/cscope.out" endif execute "cd " . curdir endfunction call SetCscope()
回答15:
Another iteration on the SetCscope() function above. That sets cscope pre-path to get matches without being on the dir where "cscope.out" is:
function s:FindFile(file) let curdir = getcwd() let found = curdir while !filereadable(a:file) && found != "/" cd .. let found = getcwd() endwhile execute "cd " . curdir return found endfunction if has('cscope') let $CSCOPE_DIR=s:FindFile("cscope.out") let $CSCOPE_DB=$CSCOPE_DIR."/cscope.out" if filereadable($CSCOPE_DB) cscope add $CSCOPE_DB $CSCOPE_DIR endif command -nargs=0 Cscope !cscope -ub -R & endif
