macros - An easy way to center text between first and last non-white word in vim? -

is there easy way using macro or ~10 line function (no plugin!) center text between first , last word (=sequence of non-blank characters) on line? e.g. turn

        >>> no user serviceable parts below.               <<< 

into

        >>>       no user serviceable parts below.         <<< 

by balancing spaces +/-1? can assume no tabs , result should not contain tabs, note first word may not start in column 1. (edit: ... in fact, both delimiter words start , end of text center may on arbitrary columns.)

source function:

fun! centerinspaces()     let l   = getline('.')     let lre = '\v^\s*\s+\zs\s*\ze'     let rre = '\v\zs\s*\ze\s+\s*$'     let sp  = matchstr(l,lre)     let sp  = sp.matchstr(l,rre)     let ln  = len(sp)     let l   = substitute(l,lre,sp[:ln/2-1],'')     let l   = substitute(l,rre,sp[ln/2:],'')     call setline('.',l) endf 

note

• this function might not work in cases. wrote quick usual case. not plugin after all

• the codes lines reduced combining function calls. think clear in way, leave this.

• if worked you, create map

• it works this: (last 2 lines typed @: repeat cmd call)
