vim正确加区间注释

fun!Jzsqj() range
"\加注释区间,是不行的."
"\找匹配注释"
let z=Qzss()
let z="'<,'>norm I" . z
"这样,不行,要犯错误"
exe z
"每个都要加上let"
norm ^[
"退出esc"
endf

改成如下:

fun!Jzs()range
"加注释区间let i=0;jjI注释串<esc>"
let z=Qzss()
let k=Schs()
"z为类型的注释串,k为可视区间行差."
norm 0;
let s:ss='norm! {}jI{}'
"先选定区间,再I加上内容,最后esc"
let m=Thgs(s:ss,k,z)
exe m
norm ^[
endf
