Hi,

Now it seems that we have not allowed to register the callback functions since beta 2010.02.18.

For example:

\startluacode

local old_pre_linebreak_filter = callback.find ('pre_linebreak_filter')

local function my_pre_linebreak_filter (head, groupcode) if old_pre_linebreak_filter then old_pre_linebreak_filter (head, groupcode) end print ('This is my pre_linebreak_callback') return true end

callback.register ('pre_linebreak_filter', my_pre_linebreak_filter)

\stopluacode

\starttext

This is just a test!

\stoptext

The 'my_pre_linebreak_filter' function can not work again. Is this a bug?

I see. The 'pre_linebreak_filter' callback function is frozen.

indeed as otherwise you kick out functionality; there are two user hooks: tasks.appendaction("processors","before","modules.mine.whatever_a") tasks.appendaction("processors","after","modules.mine.whatever_b") as it's impossible to forsee what interference happens it will be clear that there is no support beyonf this Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
