You're missing something :-) If you are using the matchText function you
must remember you still need your capturing parenthesis
\( will find a single opening parenthesis
[(] will find a single opening parenthesis
[\(] will find a single opening parenthesis or back slash
in the msg box - change the commented line to test each:
put "here is some (text in brackets) and some not." into tStore
if (matchText(tStore,"(\()",tFound) = true) then
--if (matchText(tStore,"([(])",tFound) = true) then
--if (matchText(tStore,"([\(])",tFound) = true) then
put tFound into msg
--in all cases '(text' should end up in the msg box
put "Not Found" into msg
LC uses PCRE regex which can be tested here:
Make sure PCRE is checked in the left hand column. If it works here it will
work in LC - but you still must remember to add the quotes and if you are
looking for more than a simple true or false, then you'll need to add the
capturing parenthesis - but this too can be tested at the above site, the
matches will appear in the second window down in the right hand column.
