Tip: #1107 - J2ME development

If you are same as me, using Vim to write mobile program (J2ME), you may try this.

I did a search during the weekend, no luck to find similar tips/scripts, so i tried to collect some and put it there, it works for me, but rather hardcode, especially on emulator part, it's not perfect, welcome for any comments =)

Edit: c:\progra~1\vim\_vimrc, put these:

set makeprg=jikes\ -nowarn\ -classpath\ tmpclasses\ -d\ tmpclasses\ -sourcepath\ src\ -Xstdout\ +E\ % 
set errorformat=%f:%l:%c:%*\\d:%*\\d:%*\\s%m

map <M-1> :make<CR>:cw5<CR> 
" cw5 help you to see the error, my favorite, (stolen from :help :cn) 
map <M-2> :!preverify -classpath c:\wtk22\lib\cldcapi10.jar;c:\wtk22\lib\midpapi10.jar -d bin tmpclasses<CR> 
" preverify is important before running the WTK emulator, i use Alt-2 to do this, may change. 

" This emulator is specific for ZhanGuo project: (change zhanguo.jad to yourfile.jad) 
" it's the best that the jad is generated by WTK22 such that it 
" place it in : c:\wtk22\apps\zhanguo (zhanguo is your project name) 
map <M-3> :!c:\wtk22\bin\emulator.exe -classpath bin -Xdescriptor:zhanguo.jad<CR> 

cmap %/ <C-R>=expand("%:p:h")."/"<CR>

Note on path:

You need to have path on c:\wtk22\bin (or else you need full path in many places, lazy)

SET PATH=c:\wtk22\bin;%PATH% 

Need to create 2 directories, normally created by WTK22 or by hand:

cd c:\wtk22\apps\[project] 
mkdir tmpclasses 
mkdir bin 

Also, u need to start editing in the project path, not the src path. e.g.

cd c:\wtk22\apps\[project] 
vim src\MyMidlet.java 

do not go out of the [project] path, if you need to edit another file, do:

:e %/ 

This will auto expand to the current [editing] directory. see the VimTip2, great one.
