Add a period if required

[Billykid]

There should be a punctuation mark at the end of each line. If there is no period, question mark or
exclamation mark, a period should be added there:

Code: Select all

Example:
from
str := "First sentence.`nHere is something`nThird sentence!`nHere again`nLast sentence?"
becomes:
str := "First sentence.`nHere is something.`nThird sentence!`nHere again.`nLast sentence?"

What is the regular expression for doing this?
Thank you very much for your help.

Code: Select all

#Requires AutoHotkey v1.1.33.11
str := "First sentence.`nHere is something`nThird sentence!`nHere again`nLast sentence?"
MsgBox 64, Result, % str "`n`n" fix(str)

fix(str) {
 Static regex := "m`a)[^.?!]$"
 Return RegExReplace(str, regex, "$0.")
}
