I've just started a new RoR project and thought I'd try out HAML for the views instead of rhtml.
Seeing as I just switched to JEdit, I looked for a HAML language mode, and to my surprise no one had done one yet.

I imported the rest of the Textmate ruby and rails snippets I had to combine them into the one ruby file though.
I have added about 80 new ones to the existing ones by Scott Becker that I found here

OK after expounding on how much I like Epsilon as an editor, I finally hit a wall with it. I wanted tabs of the currently open files, and it simply does not provide that facility yet. (I know all modern editors do!). On X11 (IE Linux and OS/X) Epsilon is not really a graphical app, it does open an X11 window, but within it most dialogs and lists (like buffer lists etc) are text, a little like a curses app. The advantage is it opens really fast, and loads huge files pretty fast. The downside is you don't get all those nice windowing facilities like movable pop-up windows, dialogs, trees and tabs!
So after hearing so much about JEdit, I bit the bullet and gave it a whirl. Following the instructions from a number of blogs (too numerous to mention) I installed it on my KUbuntu Linux box, with all the plugins people recommend, and of course the Ruby plugin and SupperAbbrevs (The beta version), so I have my snippets!

One of the things that bugs me about Capistrano is the requirement that access to the remote subversion repository have the same path from the local machine and the remote machine. This is never the case in my experience.
I have been getting around it by setting the path to svn://localhost/... and running ssh locally to port forward the SVN port to the remote host. This sucks as I usually forget to run ssh in another window first.

Here is a good one, your users are complaining that they have spent 5 minutes filling in a web form, then lose it all by clicking on a link away from the form, and back arrow doesn't restore the fields that were entered. (At least on IE).
I saw an interesting design in the Rails Recipes book for saving form data at regular intervals, but I didn't like the overhead of that one.

This is a simple one, how do I set the focus in the first item in my form?
Put this in your app/helpers/application_helper.rb:

I just ran into this little problem which kept me scratching my head for quite a while. My flash message didn't show up on the next action.
I have a status page which polls a database for status using
periodically_call_remote, when the database reaches a certain state I
show a button which says the process is complete go to next step.

I ran into this problem a few times,and I have seen others asking the
same question, if you use text_field_with_auto_complete and the
selection list returns non-unique results, how do you reference the
actual record in the database you want?
For instance if you have text_field_with_auto_complete :customer, :name
then in your controller: name= params[:customer][:name] and
Customer.find_all_by_name(name) returns more than one entry you need
to be a little more tricky to retrieve the actual record you wanted to
select.

I ran into a problem using text_field_with_auto_complete in a view
where I wanted to have many of them created by an iteration. You can
use the :index option for the text_field, but it doesn't carry over to
the various divs used in the AJAX calls.
<typo:code lang="ruby"> <% 0.upto(10) do |legi| %> <% @leg= @mission.legs.find(:first, :conditions => ['legnum = ?', legi]) %> text_field_with_auto_complete( :leg, :name, {:index => legi, :size => 20}) <% end %> <% end %> </typo:code>

I use Lugarus excellent Epsilon Editor for most of my programming editing needs, on Win32 and Linux.
(An exception is for Java programming where I use Eclipse).
