JScripts, my Ning app for storing JavaScript includes, has got some upgrades! At Johan‘s prodding I have added the following:

OpenID is meant as a distributed single signon protocol. Unlike corporate-only systems (ie, Google Accounts) however, you have to sign on at every single site. When I sign in to Gmail I am automatically signed in to Blogger, etc.
While the inability to store ‘cookies’ or similar across domains makes this not 100% possible, I have a suggestion that will make it easier.
Make every page on an OpenID-enabled site accept the openid_url GET parameter. If it is there, authenticate the user using that OpenID and then redirect back to the page the GET string was passed to – minus the openid_url parameter. Thus if I click a link from one OpenID-enabled site (where I am signed in) to another, I can be signed in automatically.
A browser plugin (ie, Firefox extension, or built into the browser as may come in Firefox 3) could be used to store the last-entered value into a form with text input named openid_url (dependent on user settings of course). This value would then be added to the GET request on any URL (or pertinent URL, depending) the browser goes to. OpenID-less sites won’t care, OpenID-enabled sites will automatically sign you in.

Well, not really. ‘Helper’ would be a better word. You upload an old-style template to the form and it translates most tags to the new syntax. It does not force your template to be well-formed (which is required), nor does it properly do attributes with expr: It is meant as a help for converting, not an auto-converter.
Note : especially for crufty or very-much-hacked templates (like mine was) I recommend re-engineering from scratch, from a default Blogger template, or from one of my templates. It is almost easier, and better for you in the long run.

I have added a lot of new tags and some corrections to the table.
A few people have asked for something like this. A table of Blogger Classic template tags and their new equivalent. This is not entirely possible because it is not a 1:1 relationship, but I will do my best. This is a post for those who were somewhat literate in the old Blogger and want to upgrade. Another post to check out would be Johan’s original post. Great stuff.
If you have a template tag from Blogger Classic that you don’t see here, post it in a comment and I’ll try to add it. This is a work in progress.

For how to use this syntax inside tag attributes, please see Johan at Ecmanaut. I would actually recommend that you read that whole post.

I have updated my Lightbox Comment Form (
) so that it jumps down to the form when it comes up instead of making you scroll through the comments again.
