Template::Toolkit - uc() and lc(), other simple formatting mutators

jaa has asked for the wisdom of the Perl Monks concerning the following question:

Folks,

Blush for asking a newbie Template::Toolkit question! I am more looking for general pointers in the right direction, (I know there is always a pain barrier when getting my head around a new tool...)

As an e.g. in my playing around I want to:

  [% uc(myvar) %]
[download]

But the only way I have found to do this is:

  [% use String %]
  [% String.new(myvar).upper() %]
[download]

This is a trivial example - I can imagine that I will end up implement my own class with ALL my common view mutator - upper() lower() proper() escape() commify() etc

Yes, I know about HTML.escape() and I am sure that there are date classes with formatting mutators...

Is this what everyone else does? Is there a 'better way'?

Actually I am hoping for a 'Doh!' when you point out that these are all built-ins in TT and that I have not found the right docs!

I am reluctant to do this formatting in the Model components as I see it as part of rendering an HTML view (eg escape(). I also think it kind-of breaks the 'keep it easy for template tweakers' principle.

Many thanks for your pearls!

Jeff

You have not found the right docs assuming you mean Template::Toolkit not Toolkit::Template which AFAIK does not exist. There are a swag of standard FILTERs you can use. `[% "hello world!" FILTER ucfirst %]` [download]	[reply] [d/l]

Doh! and fab! many thanks, I knew I was missing something! And this shows me how to easily create new TT filters in the Catalyst framework... (eg commify ucwords etc!) http://readlist.com/lists/lists.rawmode.org/catalyst/2/11553.html `package myApp::View::TT; use strict; use base 'Catalyst::View::TT'; __PACKAGE__->config({ CATALYST_VAR => 'catalyst', ... FILTERS => { yesno => sub { $_[0] ? 'yes' : 'no'; }, onoff => sub { $_[0] ? 'on' : 'off'; }, }, });` [download] Many many thank Monks!	[reply] [d/l]

`[% use String %] [% String.new(myvar).upper() %]` [download] Nice, but why not use a Filter: `[% myvar \| upper %]` [download] -- Frank	[reply] [d/l] [select]

If you don't find a filter that does what you want, just make your own sub ref and pass it to the template. `my $ucfirst = sub { ucfirst($_[0]) }; $template->process($template_name, { %vars, ucfirst => \&ucfirst });` [download] And then in your template... `[% ucfirst(foo) %]` [download]	[reply] [d/l] [select]
mutex? by ForgotPasswordAgain (Vicar) on Apr 23, 2008 at 11:00 UTC
I don't know much about TT, so could only give smart-alecky advice like "use HTML::Mason instead" or something. But I'm pretty sure you're using the word "mutex" incorrectly, unless there is some subtlety about locking templates that I'm missing.	[reply]

opps - sorry! mutex -> mutator	[reply]
