About regexps on Tapestry
Hello!
I have some doubts about the regexp validators in Tapestry. I have
learnt some about regexp but after making some validating with
success, I haven't been able to do two things:
1) Which flavour of regexp does Tapestry use? I have looked for it on
the Internet but I couldn't find out. I know that there are the regexp
from Javascript, Jakarta and many others but I don't know which one of
them Tapestry's belongs to.
2) Because of the former, I can't make a correct regexp for name and
surname fields. I've tried the following:
nombre-regexp=^([a-zÑñA-Z _.-])+ // This is the name
apellidos-regexp=^([a-zÑñA-Z _.-])+ // This is the surname
I'm trying to avoid all characters which are not letters, (you
shouldn't have a name containing numbers, dots....) but this is the
more accurate I got and allow numbers (not at the beginning) and it's
not what I want.
Maybe some spanish Tapestry experts around here could help me with
getting the 'ñ' spanish letter into the regular expressión, as well as
accents.
Thank you very much on advance.

AFAIK \p{Alpha}, \p{javaLowerCase}, \p{Lower} and others mentioned
all deal with ascii
If you want to match any letter in any language then
\p{L}
and that matches accented ones as well.

Re: About regexps on Tapestry

I already use quickRex, a wonderful and handy tool but I didn't know
which flavour did I have to use, so I was confused about that.
About the \p{javaLowerCase}\p{javaUpperCase}, it seems to have
problems with 'ñ' spanish letter and letters with graphical accents.
Maybe I did something wrong. I finally put:
nombre-regexp=^[\p{javaLowerCase}\p{javaUpperCase}\p{javaWhitespace}]+$
apellidos-regexp=^[\p{javaLowerCase}\p{javaUpperCase}\p{javaWhitespace}-]+$
Only added the whitespace for composite names to be possible.
Anyway, the other pattern seems to work perfectly now.
If someone is interested, these are the patterns I use:
nombre-regexp=^([a-zÑñçÇA-ZáéíóúÁÉÍÓÚ ])+
apellidos-regexp=^([a-zÑñçÇA-ZáéíóúÁÉÍÓÚ -])+
Almost identical to the Alejandro's one.
Thanks, Thiago, Martin
and Alejandro.

There are java specific operators that match letters:
\p{javaLowerCase}
\p{javaUpperCase}
So to make sure a string only contains letters (in any language) you could do this:
^[\p{javaLowerCase}\p{javaUpperCase}]+$
If you're using Eclipse you might find this plugin handy, it allows you to test regular expressions with ease:

Tapestry uses the standard Java regex flavour, described here:
http://java.sun.com/javase/6/docs/api/java/util/regex/Pattern.html.
Reading it, it looks to be very similar to the Perl 5 regex.

Hi Madtyn
Your pattern looks OK to me, it should work, just be sure the file
where you are writing the pattern is encoded in UTF-8.
This is the pattern I use: [a-zA-ZáéíóúñçÁÉÍÓÚÑÇ]+
Again, be sure your file is correctly encoded in UTF-8 and it should work.
Saludos.
