Here’s a TruncateAtWhitespace function that takes an incoming parameter value and an incoming max length, and returns a substring broken at a whitespace position. This way if you have “Lance has a blog” and you need to truncate it to 8 characters or less, you get “Lance…” instead of “Lance ha”.
PowerShell
function TruncateAtWhitespace{
param(
[string]$value,
[int]$maxlength=200
)
$maxlength-=3; #allow for "..." suffix
if ($value.Length -le $maxlength) {
return ($value + "...");
}
$closestwhitespaceindex = [int]$value.Substring(0, $maxlength).LastIndexOf(" ");
if ($closestwhitespaceindex -gt 0) {
$value = $value.Substring(0, $closestwhitespaceindex) + "...";
} else {
$value = $value.Substring(0, $maxlength);
}
return $value;
}
