问题
I use virtualenv and django in my projects and I am trying to find a more efficient way to browse django source code.
As advised here - Tools to help developers reading class hierarchy faster - I got myself set-up with ctags via
sudo port -v install ctags
and installed the vim plugin taglist via https://github.com/vim-scripts/taglist.vim
Unfortunately, it seems that ctags cannot locate my django's class when I attempted to "jump" to view a class via Ctrl+].
Any suggestions how I can get ctags to read python source code located in my virtualenv?
UPDATES
With further experimentation, I realized that ctags is some kind of "indexing" program which parses through a given directory/files/file and grabs all the keywords (class names, method names, function names etc) it finds and writes it into a file. This file can be updated and vim plugin taglist essentially reads from it to know where to send me to when I do a Ctrlt on a class/method/function name.
So I came up with a temporary and manual solution, which I execute in my vim, like this:-
:set tags=~/mytags
:! ctags -R -o ~/mytags ~/.virtualenvs/myprojectname
The first command tells my vim/taglist where my "indexed" results are stored.
The second command writes the indexed results into ~/mytags file by searching recursively (-R) down the ~/.virtualenvs/myprojectname
This works but is a very manual way to maintain tags and tags change if I happen to be in a different virtualenv environment.
Does anyone know of an automated way to manage this ctags process?
回答1:
There are many "automatic tags generation" plugins available.
TagList doesn't read from whatever tags you have manually/automatically generated: it's calling ctags itself and reads its output directly.
Also you might want to read :help autocmmand. You could setup autocommands to re-generate your tags on write like this:
autocmd BufWritePost,FileWritePost *.py :silent! !ctags -R -o ~/mytags ~/.virtualenvs/myprojectname
