[Apc-aa-coders] regular expressions in switch{} command

[Norbert B. <br...@ch...>]

I am not sure if my regexp is wrong (I am not very familiar with it) or =
is there an bug in regular expression implementation in the switch{} =
command.=20


I have this command in my view definition (test whether the field is =
empty or not):

    {switch({text...........8})[a-zA-Z0-9]:{text...........8}:none}=20

It work well until the text...........8 contains parenthesis "(" or ")". =
The switch will display "none" even if the filed is not empty (e.g. it =
contains string "Pastunovia (44 %), Tadzikovia (25 %), Hazarovia (10 %), =
Uzbeci (8 %)".

What you are testing below should I think match anything that 
contains at least one alpha-numeric character (unless implemented 
strangely in which cae it would  matche anything with EXACTLY one 
character).

It would help with looking at this bug if you

1: Make sure you are running the latest CVS version, since there has 
been work with string expansion, though not specifically on "switch".

2: Set up a slice with two items, the first working - i.e. no 
parenthesis, the second with parenthesis. Then run the view with 
"debug=1" in the URL, so that we can see detailed of what exactly is 
getting expanded into what - and how this changes between good and 
bad results.

The regular expression for not empty field is '.+', so

{switch({text...........8}).+:{text...........8}:none}=20

should work.

. The switch will display "none" even if the filed is not empty (e.g. it =

It seems there is some problem in the script. It tries to expand content =
of the field if it contains (). Here is url to the debug information"
