Phil wrote, "No arrays in UserTalk?"

We have arrays. We call them lists. Here's a list of integers:

{1, 2, 3, 4, 5}

You can add lists together if you want:

{1, 2, 3} + {4, 5} == {1, 2, 3, 4, 5}

You can reference them by index:

local (aList = {1, 2, 3});
aList[2] = 4;

After running the above, aList will contain {1, 4, 3}.

You can also mix types:

{1, "two", 0x03}

And you can nest lists:

nestedList = {1, 2, {3.0, 3.5}, 4}

In the above example, nestedList[2][1] has a value of 3.0.

Garth: Brent has written up a bunch of tips for Frontier developers, most of which apply to Radio as well. This one in particular may be of use to you.

David Davies asked me earlier today, how to get the path to a local file, given the URL for its upstreamed and rendered version. Here's a code-snippet that does it:

local (weblogurl = radio.weblog.getUrl ());
local (relpath = string.delete (url, 1, sizeOf (weblogurl)));
local (f = radio.file.getAbsolutePath (relpath));

That will work fine for an image file, but if you need the path to a rendered file. If you need to convert an .html url back to the correct filepath. Add this extra step:

radio.file.locateFileIgnoringExtension (f, @f);

At Dave's request, I started a new category for documenting my ongoing Radio development work. It's rendered in HTML here, and you can subscribe to it by clicking this link.

New Radio 8 feature. Now you can post to categories without posting to the home page. If you have categories enabled, there's a new checkbox, the first one, called Home Page (it effectively becomes a category). By default it's checked. Now you can easily publish multiple weblogs, going to lots of different locations, from one edit box. Screen shot. [Scripting News]

Garth wants to know if it's still possible to open a Manila site in the outliner in Radio 8.0.

It is. Bring the Radio application to the front, and choose File->Open Manila Site, and then type your Manila site's URL.
