Just like Tatey, I use Smultron for creating .ss files.

For CSS, I use CSSEdit.

I also have the same problems with whitespace, and indentation. Having elements indented like blocks in PHP makes tracking page flow easier, IMHO anyways.

phpDesigner 2008 with all possible add-ons =] VERY powerful. parsing the php code live is nice ;)
as for the .ss files, I have just created a new file type that is parsed similarly to html sites

After using the Mac platform for over 6 months now, I've since adopted TextMate based on the recommendations of various developers. I highly recommend it to anyone developing on OS X.

Notepad++ for all my coding.

eclipse with the Aptana plugin and additional php plug in from Aptana. Its very nice. CSS editing Live PHP error handling and add .SS to Window => preferences => General => Content Types expand >Text and select HTML Source Files to get html code complete. Also comes with built in FTP and full Ajax Server.

Exactly the info I was searching for too. I usually use NuSphere PHPEd, but for something like silverstripe, Dreamweaver would be more complete but for two problems that I can't work out:

1. How to let Dreamweaver search through .ss files (or any other non-standard extension)
2. How to setup up Dreamweaver to treat .ss files as HTML with code colouring and auto completion as SLJ stated.

SLJ, can you you comment please?

Cheers

Well, managed to setup SS files to be recognised as HTML in Dreamweaver.

Now just to work out how to colour highlight the ASP style SS tags and why I cannot do a source search in SS files.

Add SS extension to:

C:\Program Files\Adobe\Adobe Dreamweaver CS3\configuration\DocumentTypes\MMDocumentTypes.xml

<documenttype id="HTML" internaltype="HTML" winfileextension="html,htm,shtml,shtm,stm,tpl,lasso,xhtml,ss" macfileextension="html,htm,shtml,shtm,tpl,lasso,xhtml,ssi" file="Default.html" writebyteordermark="false">

Open Up C:\Documents and Settings\<username>\Application Data\Adobe\Dreamweaver 9\Configuration\CodeColoring\CodeColoring.xml

Paste the following between in the top under the <codeColoring> tag

<scheme name="SilverStripe Template" id="SilverStripe_Template" priority="21">

The above rules are a work in progress and a probably not entirely correct but is a good start.

If anyone improves on this please post back here.

Thanks
