RE: regular expression problem

How about this one:
replace_in_selection("^(.*[^,]),?$", "input\t\\1,", "regex")

This searches for:
Beginning of line (and start memorizing)
zero or more characters,
followed by one character which may _not_ be a comma, (and stop memorizing)
optionally a comma,
followed by end of line.

Matthijs

Hi,

Thank you for your answer. What I do is the following, which seems to be
more or less the same as your last example :
replace_in_selection("^(.+),*$", "input\t\\1,", "regex")

The idea is : I take what is in (), I add "input\t" before and "," after.
But it seems to be a greedy expression which goes to the end of line and
does not stop to the first ",".

Regards.

Eric.
