regenerate database

Hello, which command regenerates the file database, please? I'm trying to add type-my.tex file to texmf-local tree in Context minimals. I found that luatools --generate should do that job, but it does not work for me. regards Jan -- Tato zpráva byla vytvořena převratným poštovním klientem Opery: http://www.opera.com/mail/

Hello, Here a patch for luat-cbk.lua: function callbacks.register(name,func,freeze) if frozen[name] then if trace_callbacks then frozenmessage("registering",name) end return nil, name .. " is frozen" elseif freeze then frozen[name] = (type(freeze) == "string" and freeze) or "registered" return register_callback(name,func) else return register_callback(name,func) end end function callback.register(name,func) -- original if frozen[name] then if trace_callbacks then frozenmessage("registering",name) end return nil, name .. " is frozen" else return register_callback(name,func) end end (Untested...) Cheers, Peter -- Contact information: http://pmrb.free.fr/contact/

I see! >From the info found there ----------------------------------------- there are two user hooks: tasks.appendaction("processors","before","modules.mine.whatever_a") tasks.appendaction("processors","after","modules.mine.whatever_b") ----------------------------------------- it is not clear for me how to use this. So it seems that the luatex reference is useless for a context user. Is there an other documentation on this? I have found an other mechanism in 'luat-cbk.lua' which offers a pair of functions 'callbacks.push()' and 'callbacks.pop()'. But I have not made any attempts to use them. Are they useable or are they disabled too? Wolfgang

How can one center or align a float?
by Otared Kavian 09 Apr '10

09 Apr '10

Hi all, How is it possible to have a STEPchart be midaligned, or right-aligned, as one may do this with figures, tables, and FLOWcharts? An example is here: %%%%%%%%%%%% \usemodule[steps,mathml] \starttext \startbuffer[test-chart] \startSTEPtable \cell {$c=2a+3b$} \text {with $a=5$} \cell {$c=10+3b$} \text {and $b=6$} \cell {$c=10+18$} \text {we get} \cell {$c=28$} \stopSTEPtable \stopbuffer How can one center the following \type{\STEPchart}? \getbuffer[test-chart] \stoptext %%%%%%%%%%%% I should add that \startalignment[middle], or \placefigure do not have any influence on the alignment of the above example. Thanks in advance an best regards: OK

Hallo, I tried the following -------------------------------------- \starttext \startluacode local OldPreLB function MyPreLB(head,gc) texio.write_nl("########### Here I am!") OldPreLB(head,gc) end OldPreLB = callback.find('pre_linebreak_filter') callback.register('pre_linebreak_filter',MyPreLB) \stopluacode Test \stoptext -------------------------------------- but MyPreLB() is not called. What I am doing wrong here? Wolfgang

Multiple bibliographies (bib-module, mkiv)
by marfin 08 Apr '10

08 Apr '10

Hello, I need two bibliographies for my document, »Primary sources« and »Secondary sources«. Two bibliographies was created and loaded with \setupbibtex[database={prim,sec}]. But for the last step in my intention I’m looking for something to the effect that \placepublications[database=prim] or in a similar manner to \nocite{*} for every bib-database. Is there any solution or workaround? Thanks Markus

page layout
by Sebastien Mengin 08 Apr '10

08 Apr '10

Hi, Say I want to typeset a 10 x 18 cm book and print proofs on a A4 paper. Margins : top = 1cm bottom = 1.5cm left & right = 1cm I'd like crop marks to. My attempts based on the docs fail. Sorry, but this simple request is not easy to deduce directly from the beginners doc -- although I translated the chapter about page layout (sigh...) Thanks in advance. -- Sébastien Mengin Édition et logiciels libres < Mise en page avec LaTeX > http://edilibre.net
