Plugin: java code completion - vim7 omni complete

[Wishi]

Hi!

Currently I'm trying to install a PlugIn: http://www.vim.org/scripts/script.php?script_id=1785
It does enable code completion for my java files, which I edit with
vim since years.

Well... I did everything, as said:

1. I unzipped the .vim-files, put them to /opt/local/share/vim/vim71/
autoload

2. Than I edited my .vimrc like that

syntax on
set nocompatible
syntax on
set tabstop=4
set backspace=2
set ai
set noexpandtab

filetype plugin on
filetype plugin indent on
source $VIMRUNTIME/vimrc_example.vim

what I'm unsure about, but I don't get an error message:
autocmd Filetype java setlocal omnifunc=javacomplete#Complete

3. I restarted vim and opened a *.java File.

- I dont get any effect. I type i. e. System.out.... nothing happens.
Normally JavaIDEs would show some sub-classes or so. I think this new
omni complete-Feature should work the same way, should it?

Can somebody help me please. I builded vim7 with MacPorts recently.

btw:
Has anybody experice with that kind of project?

Does it work if you use

autocmd BufNewFile,BufRead *.java setlocal
omnifunc=javacomplete#Complete

If so, try your version with "*.java" insead of "java", but the above
version is more common. See `:he autocmd-events-abs` to see a list of
available autocmd events and their description.

HTH,

No... vim prompts me, when I edit a .java file:

--- Auto-Commands ---
filetypedetect BufNewFile
*.java setf java
filetypedetect BufRead
*.java setf java
Press ENTER or type command to continue

- After doing this change it looks like that.

What's really surprising: in my /opt/local/share/vim/vim7/autoload:
there're a lot of .vim files, but just one .java file (for the plugin).

Nevertheless, in the official instructions nothing is mentioned about
this file:

"install details

1. Unzip javacomplete.zip to an autoload directory, e.g. $VIM/
vimfiles/autoload
Move javacomplete.txt to help directory, e.g. $VIM/vimfiles/doc.

2. Set 'omnifunc' option. e.g.
set omnifunc=javacomplete#Complete
You can add this command in a ftplugin script like ftplugin/
java_xxx.vim.
Or, use autocmd: >
" Only do this part when compiled with support for autocommands.
if has("autocmd")

autocmd Filetype java setlocal omnifunc=javacomplete#Complete

endif"

Do you know whether this file has to somehwere else, maybe?

Strange. Do you have a `java` in your path? I.e. if you type `java`
in terminal, do you get something else than "command not found"?

I just installed javacomplete to see if it works for me, it does.
Here's what I did:

1. Download zip, extract it to Desktop
2. Terminal: mkdir -p ~/.vim/autoload
3. mv ~/Desktop/javacomplete/* ~/.vim/autoload
4. cd ~/.vim
5. mkdir doc
6. mv autoload/javacomplete.txt doc

After that, ~/.vim/autoload contained the files Reflection.java,
java_parser.vim and javacomplete.vim and ~/.vim/doc containted
javacomplete.txt.

Now I fired up vim (I tested both Carbon vim and MacVim) and executed
`:helptags ~/.vim/doc` (see `:he add-local-help` for more
information), opened a java file and typed in manually `:set
omnifunc=javacomplete#Complete`. After that, when I first used C-x C-
o, the java file was compiled into a class file, and then it Just
Worked (it completed System.out.pr successfully. Package name
completion didn't work for me).

Then I added

if has("autocmd")
autocmd Filetype java setlocal omnifunc=javacomplete#Complete
endif

to my ~/_vimrc , and from then on omnicompletion worked without
problems.

HTH,
Nico

ps: Always put local modifications in your ~/.vim directory, then
these settings are used by all vim instances you start. (`:he rtp`
gives a very terse overview).

As said, these are bad suggestions.

Allright, thanks a lot for that. After installing in ~/.vim/ and
changing my .vimrc everything works perfectly well. They should
replace this to vim.org.
