—FIRST— I want to thank everyone for the tremendous response to HAML. I’m absolutely amazed at the sheer number of sites that have switched over to HAML. I am honestly shocked at the emails I get. This started as a passion of mine and has grown into the passion of others. Special thanks for this release goes to Nathan Wiesenbaum who gives new meaning to prolific. —THE DEAL— After nearly a 90% code-base rewrite, we find our selves with a new-and-improved HAML… codenamed The Bomb. And its features are ready to _drop_! We have many, many new features available including… - Multi-class Handling - Multi-single-lines with the - character. - Blocks via Silent Scripting - Proper Error Reporting Read all about the new features at: [http://hamptoncatlin.com/2006/haml-0-2-the-bomb](http://hamptoncatlin.com/2006/haml-0-2-the-bomb) Or, just update your code off the haml trunk: svn://hamptoncatlin.com/haml/trunk The README file is far more complete now and is almost a tutorial. So, give that a read-through to find new features. -hampton. ---

Exciting! I read the tantalizing apetizers on your blog and trac site. Can’t wait for the main course to be served. Will the trac tutorial be expanded soon? How does HAML handle if-else-then constructs? I use them to selectively show menu options, for example. \<% if current\_user.has\_permission?(‘admin’) %\> \<%= link\_to “admin menu”, :controller =\> “admin”, :action =\> “menu” %\> \<% else %\> \<%= link\_to “normal menu”, :controller =\> “welcome”, :action =\> “menu” %\> \<% end %\> -Larry On 10/18/06, removed\_email\_address@domain.invalid [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) wrote: > —THE DEAL— > > - Proper Error Reporting > give that a read-through to find new features. > > -hampton. > > > – Best Regards, -Larry “Work, work, work…there is no satisfactory alternative.” — E.Taft Benson ---

Ok, thanks (or blames to) silent-scripting, you can convert this to… - if current\_user.has\_permission?(‘admin’) = link\_to “admin menu”, :controller =\> “admin”, :action =\> “menu” - else = link\_to “normal menu”, :controller =\> “welcome”, :action =\> “menu” But, my personal style-preference is doing this with menus. File: \_admin.haml .admin.menu = link\_to “admin menu”, :controller =\> “admin”, :action =\> “menu” File: \_guest.haml .guest.menu = link\_to “normal menu”, :controller =\> “welcome”, :action =\> “menu” Then, do… = render :partial =\> (current\_user.has\_permission?(‘admin’) ? ‘admin’ : ‘guest’) Keeps it a little more D.R.Y. … and obviously you usually have more than a link-difference in a menu. Though, that’s a personal style-choice. -hampton. Then, back in your o ---

Actually, we recently created a google-group called “haml”… so that’s the best place. What kind of select tag do you mean? There are rails helpers for the basic kinds, unless you have some specific need. -hampton. ---

Thanks for the reply. And add a little bit more to my understanding, how would a dropselect tag be written in HAML? Assuming: lookup model = Service ( with id, and name) Current model = Company[service\_id] Also, what is the best way to contact you about HAML, is there a mailing list, or is posting to the RubyRails list the best place?

There is a file in the Haml trunk called “REFERENCE”. Its also one of the documents on the Haml google-group. %table %tr %td= label\_for :model, :attribute %td= select :model, :attribute, @droplist That’d be the Haml for that. -hampton. ---

Nothing special. This is what I had in mind. | \<%= label\_for 'model', 'attribute' %\> | \<%= select 'model', 'attribute', @droplist %\> | | | | Is there a tutorial, and/or a reference for the HAML DSL someplace. I didn’t see anything an the plugin. -Larry On 10/28/06, removed\_email\_address@domain.invalid [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) wrote: > > – Best Regards, -Larry “Work, work, work…there is no satisfactory alternative.” — E.Taft Benson ---

Thanks for the sample and the reference. My somewhat jaded mind is having a hard time accepting that HAML might just possibly be as easy as it looks. These code samples help a lot. -Larry On 10/29/06, Hampton [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) wrote: > That’d be the Haml for that. > > > \> -- Best Regards, -Larry "Work, work, work...there is no satisfactory alternative." --- E.Taft Benson > > > > > > > > – Best Regards, -Larry “Work, work, work…there is no satisfactory alternative.” — E.Taft Benson
