[Gambas-user] Multiline RegExp

[Demosthenes Koptsis]

i used also Multiline
http://gambasdoc.org/help/comp/gb.pcre/regexp/multiline?v3

and DotAll
http://gambasdoc.org/help/comp/gb.pcre/regexp/dotall?v3

with this code

-------------------------
' Gambas class file

Private sRegExp As Regexp

Public Sub Form_Open()

  Me.Center

End

Public Sub btnMatch_Click()

  txtResults.Clear
  
  If IsNull(txtPattern.Text) Or IsNull(txtSubject.Text) Then Return
  
  sRegExp = New Regexp(txtSubject.Text, txtPattern.Text, 4)
  
  If sRegExp.Offset = -1 Then Return
  
  txtResults.Text = sRegExp.Text

End
-------------------------

1) The Subject of RegExp is:

Here is an email dimos at ...146... and text continues
Here is an email kostas at ...146... and text continues
Here is an email petros at ...146... and text continues
Here is an email paul at ...146... and text continues

2) The Pattern i use is:
(?i)\b[a-z0-9._%\-]+@[a-z0-9._%\-]+\.[A-Z]{2,4}\b

3) The result is only one email:
dimos at ...146...

and not the rest of them.

4) if i convert this pattern to grep syntax in terminal, grep gives all
4 emails. i want to implement a grep like funtcion with Gambas3

Thanks!
