Re: what should I know if I want to wrote a simple plugin like this

thanks Ben Fritz, good article, teach me a lot, but I still has some question.

 function! ConditionalPairMap(open,  close)                                                          

   let line = getline('.')                                                                           

   let col = col('.')                                                                                

   if col < col('$') || stridx(line,  a:close,  col + 1) != -1                                       

     return a:open                                                                                   

   else                                                                                              

     return a:open . a:close . repeat("\<left>",  len(a:close))                                      

   endif                                                                                             

 endf                                                                                                

                                                                                                     

inoremap <expr> ( ConditionalPairMap('(',  ')')                                                     

inoremap <expr> { ConditionalPairMap('{',  '}')                                                     

inoremap <expr> [ ConditionalPairMap('[',  ']')                                                     

inoremap <expr> /* ConditionalPairMap('/*',  '*/')                                                  

inoremap <expr> /*<space> ConditionalPairMap('/*<space>',  '*/<space>')                             

inoremap <expr> ' ConditionalPairMap("'",  "'")                                                     

inoremap <expr> " ConditionalPairMap('\"',  '\"')                                                   

autocmd FileType javascript inoremap , ,<SPACE>                                                     

autocmd FileType javascript inoremap : <SPACE>:<SPACE>

1. not works if insert ( [ { in the center of a line, only works at the end of the line, 

2. Can I use inoremap in function too? I want add this in function

 inoremap <expr> ) strpart(getline('.'), col('.')-1, 1) == ")" ? "\<Right>" : ")"

3, how can I get some API of strpart, get line, col, all of this internal functions?

4, Where I can get the syntax of vim script, like string operation, ! # symbols means

Thanks a lot

Have a look here, it will get you started and/or walk you through
