We are having some practical problems with ADDTOHEAD, see Item2066. The parameter requires does not allow to insert blocks before/in between other blocks.

Solution:
  • add params before and after

-- ArthurClemens - 18 Sep 2009

I have had a need for a feature like this in my own work (making something load before TMCE).

I have some other ideas and concerns regarding ADDTOHEAD as a piece of infrastructure for skins and plugins though... but I'll work that up in the Development web one day.

is this still needed with the changes for ZonePlugin and the rest?

-- WillNorris - 03 Apr 2010

No. Custom zones could be a way to get JS in front of all the other added parts, but within a zone you still want the ability to go before certain .js files. We still need a before param.

-- PaulHarvey - 04 Apr 2010

Surely the requires param of ADDTOZONE addresses this? Assuming all ADDTOZONE calls have a tag, that is.

Marking for Paul's feedback, since he seems to understand....

-- CrawfordCurrie - 24 Jun 2010

The requires param only caters for where you want to ensure something follows a tag. It does not help when you want something prior to the tag.

For example, some jquery libs (it's been a while, but superfish I think) will use different initialisation code-paths depending on presence of other plugins. In the case of superfish, I seem to recall that it will look for and magically make use of supersubs and hoverintent.

On one hand: we do not want superfish to always require supersubs/hoverintent, because they may be superfluous to a particular application. On the other hand, there's no other way for a Foswiki dev to ensure that these are inserted before the superfish.js other than to hack the superfish dependency, maybe with a new mysuperfish plugin.

In reality, superfish has ways for a dev to force re-initialisation or otherwise manually invoke the plugin on DOM elements with forced params to use the extra plugin functionality; still, it seems like we're missing a feature here.

I'm making this confirmed, but with enhancement priority.
