The source of a function that will do what you want can be found here.
You will also need this auxiliary function. |

What's your definition of sentence? Are we just talking basic alphanumerosymbolics (stuff you see printed on your keyboard, which you always want to see printed), or are you including the execution/handling of formatting control systems like ansi codes, mxp/xml/http tags, or color syntax codes across wrap boundaries?
If you are doing the former, you're only looking at like 10 lines at most:
| Code: |
#function MyWrap($column) {
#switch (!%isnumber($column)) {#return "First argument is not a number."}
(%null(%2)) {#return "No text to perform wrapping on."}
(1) {
#local $line $l
$text = %replace(%-2," ","|")
#forall $text {
#if ((%len($l) + %len(%i) + 1) <= $column) {
$l = %additem(%i,$l)
} {
$line = %additem(%replace($l,"|"," "),$line)%repeat(" ",($column - %len($l)))
$l = %i
}
}
$line = %additem(%replace($l,"|"," "),$line)%repeat(" ",($column - %len($l)))
#return %expandlist($line,%cr)
}
}
|
You can remove the %repeat() functions if you want, I put them in so that every line fills up the entire space to the wrap column. |
